There are several meanings of the word sense. This page is for disambiguation - there are more detailed articles on each meaning:
|
2 |

|
3 |

When a word has several meanings, one can refer to it as being used "in the sense of..." some context or other. In Simple English for instance we avoid using words in unusual senses.

|

The human sensory system is usually said to have six senses:
|
6 |
+
|
7 |
+
Other animals may have other senses. Fish have lateral lines which detect changes in the water pressure around them, and some can detect changes in electric fields around them.
|
8 |
+
|
9 |
+
Sense in this context is the meaning conveyed by language.
|
10 |
+
|
11 |
+
Another use is to flag whether an argument or statement is correct and understood. "That makes no sense" or "That is nonsense" are examples from everyday speech.
|
12 |
+
|
13 |
+
A variation of this is to say that something does not make "economic sense". Usually these words signal a political dispute or some failure to define terms correctly.
|
14 |
+
|
15 |
+
The term "common sense" is thinking based on a wide experience of life. It used to mean practical wisdom. It has a long history of being used in politics, often to mean that some idea will be accepted or rejected because of human nature (what people are like).

Separation of Powers means that the three branches of government are separated.
|
2 |
+
|
3 |
+
The three branches are as follows:-
|
4 |
+
|
5 |
+
Separation of Powers helps to protect freedom. The executive branch carries out the laws but cannot make laws to make themselves powerful. Also the judiciary is responsible for making sure that criminals are punished, so that members of the government or legislature cannot ignore the law as the judiciary can check on them.
|
6 |
+
|
7 |
+
Separation of powers is also called a system of checks and balances because the branches can check up on each other and if any of the branches get too strong, that branch will be balanced by the others.
|
8 |
+
|
9 |
+
In the United States the three branches of government are completely separate except for the Vice President who is President of the Senate. In the United Kingdom the three branches of Government are mixed but the checks and balances are provided by history and custom (the rule that says something should happen because that is how it has been done for a long time). The Queen is Head of State (the executive), but is also part of Parliament (the legislative branch) and is the Fountain of Justice (the head of the judicial branch). But by convention she does not do anything without the advice of Ministers and never refuses to pass an Act of Parliament. The Queen has a lot of power but the power is controlled and balanced by the need to act in certain ways or only use the power at certain times.
|
10 |
+
|
11 |
+
In some countries the leaders of the executive branch are members of the legislature. This system is called responsible government.
|
12 |
+
The first to talk about separation of powers in the modern age was Charles-Louis Montesquieu. Montesquieu published his book De l'esprit des lois (The Spirit of Laws) in 1748.

September (Sep.) is the ninth month of the year in the Gregorian calendar, coming between August and October. It has 30 days. Its name comes from the Latin word sept for "seven" (it was the seventh month of the year, before January and February were added to the beginning of the year.)
|
2 |
+
|
3 |
+
September always begins on the same day of the week as December, but never ends on the same day of the week as any other month.
|
4 |
+
|
5 |
+
In the old Roman calendar, September was the seventh month, which is where it got its name ("Septem" means "seventh"). The ninth month at the time was November ("Novem" means "ninth"). With Julius Caesar's calendar reform, September became the ninth month, with 30 days. September comes after August and before October.
|
6 |
+
|
7 |
+
September begins on the same day of week as December every year, as each other's first days are 13 weeks (91 days) apart. No other month in any year, common or leap year, ends on the same day of the week as September.
|
8 |
+
|
9 |
+
In common years, September starts on the same day of the week as April and July of the previous year, and in leap years, October of the previous year. In common years, September finishes on the same day of the week as April and December of the previous year, and in leap years, July of the previous year. In leap years and years immediately after that, September starts on the same day of the week as January of the previous year.
|
10 |
+
|
11 |
+
In years immediately before common years, September starts on the same day of the week as June of the following year, and in years immediately before leap years, March and November of the following year. In years immediately before common years, September finishes on the same day of the week as March and June of the following year, and in years immediately before leap years, August and November of the following year.

September is one of two months to have an equinox (the other is March, its seasonal equivalent in both hemispheres), where both day and night are roughly of equal length, occurring either on the 22nd or 23rd, halfway between the June and December solstices. In the Northern Hemisphere, Autumn (Fall) begins in this month, while in the Southern Hemisphere, this is the beginning of Spring. For meteorologists, the people who study the weather, these seasons begin on September 1 in those hemispheres. In most Northern Hemisphere countries, school starts in this month, following the summer holidays.
|
14 |

|
15 |

In Ancient Greece, September was called Boedromion. The Anglo-Saxons called it Gerstmonath, meaning "Barley month", referring to the harvest. In other countries, it is referred to as Autumn Month, such as in Finland (Syyskuu) and German-speaking parts of Switzerland (Herbstmonat).

Ethiopian New Year occurs in September. Jewish New Year also often occurs in this month.

The Seven Wonders of the World (or the Seven Wonders of the Ancient World) is a widely-known list of seven great buildings or structures from the classical time period.

This is a list put together in the 2nd century BC by

Antipater of Sidon and Philon of Byzantium. This explains why it only lists monuments of the Mediterranean world. There are other slightly different versions: this is the most usual one.
|
5 |

New7Wonders of the World was an idea to choose new wonders of the world from a selection of 200 existing monuments.[1] The mission began in 2001 and ended in 2007 with the announcement of the winners. The popularity poll was led by Canadian-Swiss Bernard Weber and organized by the New7Wonders Foundation in Zürich, Switzerland. Voting took place through the Internet or by telephone.

There is no comparison between Mr. Weber's mediatised campaign and the scientific and educational work resulting from the inscription of sites on UNESCO's World Heritage List.

The Baltic Sea is a sea in northern Europe between Scandinavia, Finland, Russia, the Baltic countries, Poland, and Germany.
|
2 |
+
|
3 |
+
Many big rivers in the surrounding countries drain into the Baltic Sea. The Baltic Sea is connected to the ocean through the narrow and shallow Danish straits and belts. For this reason, the water has a low amount of salt, so the northern parts of the sea freeze over in the winter. The ice can carry cars, and roads are established every winter between the islands in the archipelagos between Sweden and Finland.
|
4 |
+
|
5 |
+
For several thousand years, the Baltic Sea has connected the countries at her shores. For that reason there are many cultural similarities in these countries. Since all of these countries are European, this sea is also considered European.

White Serbs, an early Slavic tribe from Northern Europe, came to Northern Greece in the 6th century. By the 8th century they had created the Serbian Principality, a Serbian country, in the Balkans.[9] The Serbs became Christian around the 10th century. For 200 years, the Nemanjić dynasty ruled. They made Serbia a kingdom, built new towns, monasteries, and forts, and made Serbia bigger. In 1371 the Nemanjic Dynasty died out. Serbia became unsafe and local leaders fought each other for control. In 1389 the Ottoman Empire invaded Serbia. They fought against Serbia, Bosnia, the Knights Hospitaller, and the forces of many other local leaders, and won. The Turks fought the Serbs for 70 years until in 1459 the Ottoman Turks conquered Serbia.[10]

Once the Ottomans conquered Serbia, they got rid of the Serbian upper class. Most Serbs worked as farmers on land owned by Turks. They had to pay high taxes to the Turks. Some Serbs were forced to become Muslims. But the Serbs had their own laws in the Ottoman Empire through the millet system.[11][12] During the 19th century Serbia gradually became independent. During World War I Austria conquered Serbia but lost the bigger war. Serbia joined other Balkan countries to form Yugoslavia.

Sexual reproduction is how most animals and plants reproduce.[1] Some protists and fungi also reproduce this way. Organisms that reproduce sexually have two different sexes: male and female.
|
2 |
+
|
3 |
+
In sexual reproduction, offspring are produced when sperms fertilise eggs from the female. Various steps are involved in this process.[2]
|
4 |
+
|
5 |
+
The cells of an animal or higher plant have two sets of chromosomes: they are diploid. When gametes (sex cells) are produced, they have only one set of chromosomes: they are haploid. They have undergone a process of cell division called meiosis. Two things happen during meiosis, each of which makes the offspring more variable. That means they are different from the parents and from each other.
|
6 |
+
|
7 |
+
Assortment is when the double set of chromosomes becomes a single set in each gamete. Of each pair of chromosomes, which one goes into a single gamete is random. Because the gene alleles on each chromosome are not always the same, this means that there is genetic variation between gametes. This process was Mendel's 'first law', the law of segregation.
|
8 |
+
|
9 |
+
Because crossing over occurs during meiosis, this increases the variety of the chromosomes. This makes recombination possible.
|
10 |
+
|
11 |
+
The consequence of assortment and crossing over makes it certain that no two offspring of the same mother and father are identical. Identical twins are the exception. They are identical genetically because they developed from the same fertilised egg.

There are advantages and disadvantages of sexual reproduction, compared to asexual reproduction. The main issues are:

Snakes are reptiles. They are part of the order Squamata. They are carnivores, with long narrow bodies and no legs. There are at least 20 families, about 500 genera and 3,400 species of snake.[2][3]
|
4 |
+
|
5 |
+
The earliest known fossils are from the Jurassic period. This was between 143 and 167 million years ago.[4]
|
6 |
+
|
7 |
+
Their long, slender body has some special features.[5] They have overlapping scales which protect them, and help them move and climb trees. The scales have colours which may be camouflage or warning colours.
|
8 |
+
|
9 |
+
Many species have skulls with more joints than the skulls of their lizard ancestors. This allows the snakes to swallow prey much larger than their heads. In their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side. Most have only one working lung. Some species have kept a pelvic girdle with a pair of vestigial claws on either side of the cloaca. They have no eyelids or external ears. They can hiss, but otherwise make no vocal sounds.
|
10 |
+
|
11 |
+
They are very mobile in their own way. Most of them live in the tropics. Few snake species live beyond the Tropic of Cancer or Tropic of Capricorn, and only one species, the common viper (Vipera berus) lives beyond the Arctic Circle.[5] They can see well enough, and they can taste scents with their tongues by flicking them in and out. They are very sensitive to vibrations in the ground. Some snakes can sense warm-blooded animals by thermal infrared.
|
12 |
+
|
13 |
+
Most snakes live on the ground, and in the trees. Others live in the water, and a few live under the soil. Like other reptiles, snakes are ectotherms. They control their body temperature by moving in and out of the direct sunshine. That is why they are rare in cold places.[6]
|
14 |
+
|
15 |
+
Snakes range in size from the tiny, 10.4 cm (4 inch)-long thread snake[7] to the reticulated python of 6.95 meters (22.8 ft) in length.[8] The extinct snake Titanoboa was 12.8 meters (42 ft) long.[9]
|
16 |

|
17 |

Snakes are thought to have evolved from lizards. The earliest snake fossils are from the Lower Cretaceous.[10] A wide range of snakes appeared during the Paleocene period (c 66 to 56 million years ago).

The Squamata are definitely a monophyletic group: it is a sister group to the Tuatara. Judged by their fossil record, the squamates were present in the Mesozoic, but had a minor place in the land ecology. Three of the six lines are recorded first in the Upper Jurassic, the others in the Cretaceous. Probably all, certainly the lizards, arose earlier in the Jurassic.[11] The Mosasaurs of the Upper Cretaceous were by far the most successful of all the lizards, becoming the top predator in their ecosystem.

Although snakes and lizards look very different, neither is a proper clade. Snakes did descend from early lizards, not once, but a number of times.

There is a monophyletic clade within the Squamata. It is the Toxicofera. It includes all venomous snakes and lizards, and many related non-venomous species. The evidence for this is in recent molecular analyses.[12][13][14][15][16][17][18]

The fossil of a primitive snake from the Lower Cretaceous has been found. It lived about 113 million years ago.[19] It had rather small front and rear legs. Several other fossil snakes have been found with small rear legs, but this is the first one with all four legs. The snake, Tetrapodophis amplectus, lived on land and was adapted to burrowing. The researcher said there were "a lot of very advanced snake features, including its hooked teeth, flexible jaw and spine – and even snake-like scales. And there's the gut contents – it's swallowed another vertebrate. It was preying on other animals, which is a snake feature".[20] The snake came from the Crato Formation in Brazil, and lay in a private collection for many years. It was re-discovered in a museum at Solnhofen, Bavaria.

Most snakes are nonvenomous. Those that have venom use it mainly to kill and subdue prey rather than for self-defense. Some have venom potent enough to cause painful injury or death to humans. Nonvenomous snakes either swallow prey alive or kill by squeezing.

Many snakes have skulls with more joints than their lizard ancestors. This helps them swallow prey much larger than their heads. The bones of the head and jaws can move apart to let large prey move into their body. The throat, stomach and intestines can also expand in a most extraordinary manner. In this was, a thin-looking snake can swallow and digest a larger animal.

To fit their narrow bodies, snakes' paired organs (such as kidneys) are one in front of the other instead of side by side, and most snakes have only one working lung.

Snakes need to shed their skin regularly while they grow. This is called moulting. Snakes shed their skin by rubbing their head against something rough and hard, like a piece of wood or a rock. This causes the skin, which is already stretched, to split open. The snake keeps on rubbing its skin on various rough objects until the skin peels off from its head. This lets it crawl out, turning the skin inside out.
|
38 |
+
|
39 |
+
All snakes are carnivorous; they eat other animals. Some are venomous; they inject poison along grooves in their teeth. Some snakes are constrictrors. Constrictors are not venomous, so they squeeze their prey to death. Snakes swallow their food whole, and they cannot chew.[23] Because snakes are cold-blooded, they do not have to eat as regularly as mammals. People who own pet snakes feed them as infrequently as once per month. Some snakes can go as long as six months without a good meal.
|
40 |
+
|
41 |
+
Snakes have a very flexible lower jaw, the two halves of which are not rigidly attached, and many other joints in their skull. They can open their mouths wide enough to swallow their prey whole, even if the prey is larger in diameter than the snake itself.[24]
|
42 |
+
|
43 |
+
Not having arms and legs doesn't stop snakes from moving. They have developed several different ways of moving to deal with particular environments. Each type of snake movement is discrete and distinct from the others.[25][26]
|
44 |
+
|
45 |
+
Lateral undulation is a snake's only way of moving in water, and the most common way of moving altogether.[26] In this mode, the body of the snake alternately bends to the left and right, resulting in a series of rearward-moving "waves".[25] While this movement appears rapid, snakes have rarely been seen moving faster than two body-lengths per second, often much less.[27] This mode of movement has the same amount of calories burned per meter moved as running in lizards of the same mass.[28]
|
46 |
+
|
47 |
+
Terrestrial lateral undulation is the most common mode of moving for most snake species.[25] In this mode, the posteriorly moving waves push against contact points in the environment, such as rocks, twigs, irregularities in the soil, etc.[25] Each of these environmental objects, in turn, generates a reaction force directed forward and towards the midline of the snake, resulting in forward thrust while the lateral components cancel out.[29] The speed of this movement depends upon the density of push-points in the environment, with a medium density of about 8 along the snake's length being ideal.[27] The wave speed is precisely the same as the snake speed, and as a result, every point on the snake's body follows the path of the point ahead of it, allowing snakes to move through very dense vegetation and small openings.[29]
|
48 |
+
|
49 |
+
Snakes move forward in water by moving their bodies in a wave-like motion. The waves become larger as they move down the snake's body, and the wave travels backwards faster than the snake moves forwards.[30] Thrust is got by pushing their body against the water: this results in the observed slip. In spite of overall similarities, studies show that the pattern of muscle activation is different in aquatic versus terrestrial lateral undulation, which justifies calling them separate modes.[31] All snakes can laterally undulate forward (with backward-moving waves), but only sea snakes have been observed reversing the motion (moving backwards with forward-moving waves).[25]
|
50 |
+
|
51 |
+
This is most often used by colubroid snakes (colubrids, elapids, and vipers). They use it when the environment lacks anything firm to push against, such as a slick mud flat, or a sand dune. Sidewinding is a modified form of lateral undulation in which all of the body segments oriented in one direction remain in contact with the ground, while the other segments are lifted up. This results in a peculiar "rolling" motion.[32][33] This mode of moving overcomes the slippery nature of sand or mud by pushing off with only static portions on the body, thereby minimizing slipping.[32] The static nature of the contact points can be shown from the tracks of a sidewinding snake, which show each belly scale imprint, without any smearing. This mode of moving has very low caloric cost, less than ⅓ of the cost for a lizard or normal snake to move the same distance.[28]
|
52 |
+
|
53 |
+
When push-points are absent, but the space is too narrow for sidewinding, such as in tunnels, snakes rely on concertina moving.[25][33] In this mode, the snake braces the back part of its body against the tunnel wall while the front of the snake extends and straightens.[32] The front portion then flexes and forms an anchor point, and the back part is straightened and pulled forwards. This mode of moving is slow and very demanding, needing up to seven times the energy of laterally undulating over the same distance.[28] This high cost is due to the repeated stops and starts of portions of the body as well as the need to use the muscles to brace against the tunnel walls.
|
54 |
+
|
55 |
+
The slowest mode of snake moving is rectilinear moving, which is also the only one where the snake does not need to bend its body laterally, though it may do so when turning.[34] In this mode, the belly scales are lifted and pulled forward before being placed down and the body pulled over them. Waves of movement and stasis pass posteriorly, resulting in a series of ripples in the skin.[34] The ribs of the snake do not move in this mode of moving and this method is most often used by large pythons, boas, and vipers when stalking prey across open ground as the snake's movements are subtle and harder to detect by their prey in this manner.[32]
|
56 |
+
|
57 |
+
The movement of snakes in trees has only recently been studied.[35] While on tree branches, snakes use several modes of moving depending on species and bark texture.[35] In general, snakes will use a modified form of concertina moving on smooth branches, but will laterally undulate if contact points are available.[35] Snakes move faster on small branches and when contact points are present, in contrast to limbed animals, which do better on large branches with little 'clutter'.[35]
|
58 |
+
|
59 |
+
Gliding snakes (Chrysopelea) of Southeast Asia launch themselves from branch tips, spreading their ribs and laterally undulating as they glide between trees.[32][36][37] These snakes can perform a controlled glide for hundreds of feet depending upon launch altitude and can even turn in midair.[32][36]

This results in a peculiar "rolling" motion.[32][33] This mode of moving overcomes the slippery nature of sand or mud by pushing off with only static portions on the body, thereby minimizing slipping.[32] The static nature of the contact points can be shown from the tracks of a sidewinding snake, which show each belly scale imprint, without any smearing. This mode of moving has very low caloric cost, less than ⅓ of the cost for a lizard or normal snake to move the same distance.[28]

52 |

|
53 |

When push-points are absent, but the space is too narrow for sidewinding, such as in tunnels, snakes rely on concertina moving.[25][33] In this mode, the snake braces the back part of its body against the tunnel wall while the front of the snake extends and straightens.[32] The front portion then flexes and forms an anchor point, and the back part is straightened and pulled forwards. This mode of moving is slow and very demanding, needing up to seven times the energy of laterally undulating over the same distance.[28] This high cost is due to the repeated stops and starts of portions of the body as well as the need to use the muscles to brace against the tunnel walls.

The slowest mode of snake moving is rectilinear moving, which is also the only one where the snake does not need to bend its body laterally, though it may do so when turning.[34] In this mode, the belly scales are lifted and pulled forward before being placed down and the body pulled over them. Waves of movement and stasis pass posteriorly, resulting in a series of ripples in the skin.[34] The ribs of the snake do not move in this mode of moving and this method is most often used by large pythons, boas, and vipers when stalking prey across open ground as the snake's movements are subtle and harder to detect by their prey in this manner.[32]

The movement of snakes in trees has only recently been studied.[35] While on tree branches, snakes use several modes of moving depending on species and bark texture.[35] In general, snakes will use a modified form of concertina moving on smooth branches, but will laterally undulate if contact points are available.[35] Snakes move faster on small branches and when contact points are present, in contrast to limbed animals, which do better on large branches with little 'clutter'.[35]

Gliding snakes (Chrysopelea) of Southeast Asia launch themselves from branch tips, spreading their ribs and laterally undulating as they glide between trees.[32][36][37] These snakes can perform a controlled glide for hundreds of feet depending upon launch altitude and can even turn in midair.[32][36]

Snakes are reptiles. They are part of the order Squamata. They are carnivores, with long narrow bodies and no legs. There are at least 20 families, about 500 genera and 3,400 species of snake.[2][3]
|
4 |
+
|
5 |
+
The earliest known fossils are from the Jurassic period. This was between 143 and 167 million years ago.[4]
|
6 |
+
|
7 |
+
Their long, slender body has some special features.[5] They have overlapping scales which protect them, and help them move and climb trees. The scales have colours which may be camouflage or warning colours.
|
8 |
+
|
9 |
+
Many species have skulls with more joints than the skulls of their lizard ancestors. This allows the snakes to swallow prey much larger than their heads. In their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side. Most have only one working lung. Some species have kept a pelvic girdle with a pair of vestigial claws on either side of the cloaca. They have no eyelids or external ears. They can hiss, but otherwise make no vocal sounds.
|
10 |
+
|
11 |
+
They are very mobile in their own way. Most of them live in the tropics. Few snake species live beyond the Tropic of Cancer or Tropic of Capricorn, and only one species, the common viper (Vipera berus) lives beyond the Arctic Circle.[5] They can see well enough, and they can taste scents with their tongues by flicking them in and out. They are very sensitive to vibrations in the ground. Some snakes can sense warm-blooded animals by thermal infrared.
|
12 |
+
|
13 |
+
Most snakes live on the ground, and in the trees. Others live in the water, and a few live under the soil. Like other reptiles, snakes are ectotherms. They control their body temperature by moving in and out of the direct sunshine. That is why they are rare in cold places.[6]
|
14 |
+
|
15 |
+
Snakes range in size from the tiny, 10.4 cm (4 inch)-long thread snake[7] to the reticulated python of 6.95 meters (22.8 ft) in length.[8] The extinct snake Titanoboa was 12.8 meters (42 ft) long.[9]
|
16 |
+
|
17 |
+
Snakes are thought to have evolved from lizards. The earliest snake fossils are from the Lower Cretaceous.[10] A wide range of snakes appeared during the Paleocene period (c 66 to 56 million years ago).

The Squamata are definitely a monophyletic group: it is a sister group to the Tuatara. Judged by their fossil record, the squamates were present in the Mesozoic, but had a minor place in the land ecology. Three of the six lines are recorded first in the Upper Jurassic, the others in the Cretaceous. Probably all, certainly the lizards, arose earlier in the Jurassic.[11] The Mosasaurs of the Upper Cretaceous were by far the most successful of all the lizards, becoming the top predator in their ecosystem.
|
20 |

|
21 |
+
Although snakes and lizards look very different, neither is a proper clade. Snakes did descend from early lizards, not once, but a number of times.
|
22 |
+
|
23 |
+
There is a monophyletic clade within the Squamata. It is the Toxicofera. It includes all venomous snakes and lizards, and many related non-venomous species. The evidence for this is in recent molecular analyses.[12][13][14][15][16][17][18]
|
24 |

The fossil of a primitive snake from the Lower Cretaceous has been found. It lived about 113 million years ago.[19] It had rather small front and rear legs. Several other fossil snakes have been found with small rear legs, but this is the first one with all four legs. The snake, Tetrapodophis amplectus, lived on land and was adapted to burrowing. The researcher said there were "a lot of very advanced snake features, including its hooked teeth, flexible jaw and spine – and even snake-like scales. And there's the gut contents – it's swallowed another vertebrate. It was preying on other animals, which is a snake feature".[20] The snake came from the Crato Formation in Brazil, and lay in a private collection for many years. It was re-discovered in a museum at Solnhofen, Bavaria.

Most snakes are nonvenomous. Those that have venom use it mainly to kill and subdue prey rather than for self-defense. Some have venom potent enough to cause painful injury or death to humans. Nonvenomous snakes either swallow prey alive or kill by squeezing.

Many snakes have skulls with more joints than their lizard ancestors. This helps them swallow prey much larger than their heads. The bones of the head and jaws can move apart to let large prey move into their body. The throat, stomach and intestines can also expand in a most extraordinary manner. In this was, a thin-looking snake can swallow and digest a larger animal.
|
34 |
+
|
35 |
+
To fit their narrow bodies, snakes' paired organs (such as kidneys) are one in front of the other instead of side by side, and most snakes have only one working lung. Some species have a pelvic girdle with a pair of vestigial claws on either side of the cloaca. This is a relic of the legs which do not appear in modern snakes.
|
36 |
+
|
37 |

Snakes need to shed their skin regularly while they grow. This is called moulting. Snakes shed their skin by rubbing their head against something rough and hard, like a piece of wood or a rock. This causes the skin, which is already stretched, to split open. The snake keeps on rubbing its skin on various rough objects until the skin peels off from its head. This lets it crawl out, turning the skin inside out.
|
38 |
+
|
39 |
+
All snakes are carnivorous; they eat other animals. Some are venomous; they inject poison along grooves in their teeth. Some snakes are constrictrors. Constrictors are not venomous, so they squeeze their prey to death. Snakes swallow their food whole, and they cannot chew.[23] Because snakes are cold-blooded, they do not have to eat as regularly as mammals. People who own pet snakes feed them as infrequently as once per month. Some snakes can go as long as six months without a good meal.
|
40 |
+
|
41 |
+
Snakes have a very flexible lower jaw, the two halves of which are not rigidly attached, and many other joints in their skull. They can open their mouths wide enough to swallow their prey whole, even if the prey is larger in diameter than the snake itself.[24]
|
42 |
+
|
43 |
+
Not having arms and legs doesn't stop snakes from moving. They have developed several different ways of moving to deal with particular environments. Each type of snake movement is discrete and distinct from the others.[25][26]
|
44 |
+
|
45 |
+
Lateral undulation is a snake's only way of moving in water, and the most common way of moving altogether.[26] In this mode, the body of the snake alternately bends to the left and right, resulting in a series of rearward-moving "waves".[25] While this movement appears rapid, snakes have rarely been seen moving faster than two body-lengths per second, often much less.[27] This mode of movement has the same amount of calories burned per meter moved as running in lizards of the same mass.[28]
|
46 |
+
|
47 |
+
Terrestrial lateral undulation is the most common mode of moving for most snake species.[25] In this mode, the posteriorly moving waves push against contact points in the environment, such as rocks, twigs, irregularities in the soil, etc.[25] Each of these environmental objects, in turn, generates a reaction force directed forward and towards the midline of the snake, resulting in forward thrust while the lateral components cancel out.[29] The speed of this movement depends upon the density of push-points in the environment, with a medium density of about 8 along the snake's length being ideal.[27] The wave speed is precisely the same as the snake speed, and as a result, every point on the snake's body follows the path of the point ahead of it, allowing snakes to move through very dense vegetation and small openings.[29]
|
48 |
+
|
49 |
+
Snakes move forward in water by moving their bodies in a wave-like motion. The waves become larger as they move down the snake's body, and the wave travels backwards faster than the snake moves forwards.[30] Thrust is got by pushing their body against the water: this results in the observed slip. In spite of overall similarities, studies show that the pattern of muscle activation is different in aquatic versus terrestrial lateral undulation, which justifies calling them separate modes.[31] All snakes can laterally undulate forward (with backward-moving waves), but only sea snakes have been observed reversing the motion (moving backwards with forward-moving waves).[25]
|
50 |
+
|
51 |
+
This is most often used by colubroid snakes (colubrids, elapids, and vipers). They use it when the environment lacks anything firm to push against, such as a slick mud flat, or a sand dune. Sidewinding is a modified form of lateral undulation in which all of the body segments oriented in one direction remain in contact with the ground, while the other segments are lifted up. This results in a peculiar "rolling" motion.[32][33] This mode of moving overcomes the slippery nature of sand or mud by pushing off with only static portions on the body, thereby minimizing slipping.[32] The static nature of the contact points can be shown from the tracks of a sidewinding snake, which show each belly scale imprint, without any smearing. This mode of moving has very low caloric cost, less than ⅓ of the cost for a lizard or normal snake to move the same distance.[28]

The serval (Leptailurus serval) is a medium-sized wild cat which lives in sub-Saharan Africa. It is the only species in its genus.
|
4 |
+
|
5 |
+
The serval has the longest legs of all cats, relative to its size.[3] Not only can it run fast, but it is an amazing jumper: two to three metres from a standing start.
|
6 |
+
|
7 |
+
Its length as an adult is about 32 inches (body) and 16 inches (tail). It weighs about four pounds.[4] There are a number of subspecies, and its geographical range is from the Cape of South Africa to Algeria, wherever the circumstances are right for it.
|
8 |
+
|
9 |
+
It is lightly built, with very large ears and long legs. The back of the ears is black with a big white spot, and the tip of the tail is black. These signs serve as signals to other servals, including kittens.[4]
|
10 |
+
|
11 |
+
The serval needs access to water, and dense grassland. Reed beds, scrub or high grass are typical habitats. It is territorial.[4]
|
12 |
+
|
13 |
+
The serval is nocturnal, and hunts mostly at night. The serval is an opportunistic predator whose diet includes rodents, hares, hyraxes, birds, reptiles, insects, fish, and frogs.[5]
|
14 |
+
|
15 |
+
As part of its adaptations for hunting in the savannas, the serval's long legs help it achieve a top speed of 80 kilometres per hour (50 mph), and has large ears with acute hearing. Its long legs and neck allow the serval to see over tall grasses, while its ears are used to detect prey, even those burrowing underground. Servals have been known to dig into burrows in search of underground prey, and to leap 2 to 3 metres (7 to 10 ft) into the air to grab birds in flight.[6] Using its spectacular jumping ability, the serval leaps into the air and bats the bird with its front paws. When the bird is on the ground, it bites its neck, killing it.
|
16 |
+
|
17 |
+
Like most cats, the serval is a solitary animal. It travels as much as 3 to 4 kilometres (1.9 to 2.5 mi) each night in search of food. The female defends home ranges of 9.5 to 19.8 square kilometres (3.7 to 7.6 sq mi), depending on local prey availability. The male defends larger territories of 11.6 to 31.5 square kilometres (4.5 to 12.2 sq mi), and marks its territory by spraying urine onto bushes.

Slavery is when a person is treated as the property of another person. This person is usually called a slave, with the owner being called a slavemaster. It often means that slaves are forced to work, or else they will be punished by the law (if slavery is legal in that place) or by their master.

There is evidence that even before there was writing, there was slavery.[1] There have been different types of slavery, and they have been in almost all cultures and continents.[2] Some societies had laws about slavery, or they had an economy that was built on it. Ancient Greece and Ancient Rome had many slaves.
|
4 |
+
|
5 |
+
During the 20th century almost all countries made laws forbidding slavery. The Universal Declaration of Human Rights says that slavery is wrong. Slavery is now banned by international law.[3] Nevertheless, there are still different forms of slavery in some countries.[4]

The English word "slave" comes from the medieval word for the Slavic peoples of Central Europe and Eastern Europe, because these were the last ethnic group to be captured and enslaved in Central Europe.[5][6] According to Adam Smith and Auguste Comte, a slave was mainly defined as a captive or prisoner of war. Slave-holders used to buy slaves at slave auctions. In many cases slaves are not allowed rights.

Slavery has existed for a long time.[7] Early hunter-gatherers had no use for slaves.[8] They did everything for themselves. Having another pair of hands to help them meant another mouth to feed. Slavery or owning another person made no sense to these people.[8] Once men gathered in cities and towns and there was more than enough food, having a cheap supply of labor made sense.[8] This is when the earliest forms of slavery appeared. Slavery can be traced back to the earliest records, such as the Code of Hammurabi (c. 1760 BC). This refers to it as an established institution.[9]

In the Ancient Near East, captives obtained through warfare often became slaves. This was seen by the laws in the Bible book of Deuteronomy as a legal form of slavery. But the Israelites were not allowed to enslave other Israelites. The Deuteronomic Code calls for the death penalty for the crime of kidnapping Israelites to enslave them.

In Ancient Egypt, slaves were mainly prisoners of war. Other ways people could become slaves was by inheriting the status from their parents who were slaves. Someone could become a slave if he could not pay his debts. People also sold themselves into slavery because they were poor peasants and needed food and shelter. The lives of slaves were normally better than that of peasants.[10] Young slaves could not be put to hard work, and had to be brought up by the mistress of the household. Not all slaves went to houses. Some also sold themselves to temples, or were assigned to temples by the king. Slave trading was not very popular until later in Ancient Egypt. Afterwards, slave trades sprang up all over Egypt.

In many places, citizens were partly or fully protected from being enslaved, so most slaves were foreigners.

Roman slaves played an important role in society and the economy. Besides manual labor, slaves performed many domestic services. They could work at highly skilled jobs and professions. Teachers, accountants, and physicians were often slaves. Greek slaves were often highly educated. Unskilled slaves, or those sentenced to slavery as punishment, worked on farms, in mines, and at mills. Their living conditions were brutal, and their lives short.

Slaves were considered property under Roman law and had no legal personhood. Unlike Roman citizens, they could be subjected to corporal punishment, sexual exploitation (prostitutes were often slaves), torture, and summary execution. The testimony of a slave could not be accepted in a court of law unless the slave was tortured—a practice based on the belief that slaves in a position to be privy to their masters' affairs would be too virtuously loyal to reveal damaging evidence unless coerced. Over time, however, slaves gained increased legal protection, including the right to file complaints against their masters. Attitudes changed in part because of the influence among the educated elite of the Stoics, whose egalitarian views of humanity extended to slaves.

Roman slaves could hold property which, even though it belonged to their masters, they were allowed to use as if it were their own. Skilled or educated slaves were allowed to earn their own money. With enough money they could buy their freedom.[11]

After the Roman Empire broke up, slavery gradually changed into serfdom.

Historians estimate that between 650 AD and the 1960s, 10 to 18 million people were enslaved by Arab slave traders. They were taken from Europe, Asia and Africa across the Red Sea, Indian Ocean, and Sahara desert. Male slaves were often employed as servants, soldiers, or workers by their owners. Many male slaves were castrated.[12] It is estimated that as many as 6 out of every 10 boys bled to death during the process.[12] But the high price of Eunuchs made it worthwhile. According to Ronald Segal, author of Islam’s Black Slaves: The Other Black Diaspora (2002), "The calipha in Baghdad at the beginning of the 10th Century had 7,000 black eunuchs and 4,000 white eunuchs in his palace”.[12] Women and children taken as slaves were mainly used as servants and concubines. While the later Atlantic slave trade concentrated on men for labor, the Arab slave trade started with men and boys, but shifted over time to concentrate more on woman and young girls for sexual purposes. By the 1900s, Arab slave traders had taken between 10 and 20 million slaves out of Africa.[12]

For four centuries, beginning in the late 15th century, millions of Africans were taken as slaves by Europeans.[13] Europeans began exporting Africans to the New World as a source of cheap labor on colonial plantations.[13]
|
28 |

|
29 |
+
Between 1452 and 1455, Pope Nicolas V issued a series of papal bulls authorizing the Portuguese to take African slaves.[14] At first slave traders raided coastal areas and carried black people off. But the mines and fields of the colonies needed more and more slaves. In the early 16th century Spain began to issue licenses and contracts to supply slaves. By the 1750s large slaving companies were established. Most of Europe at the time was involved in the slave trade.[14]

Many Europeans who arrived in North America during the 17th and 18th centuries came under contract as indentured servants.[15] The change from indentured servitude to slavery was a gradual process in Virginia. The earliest legal documentation of such a shift was in 1640. This is where an African, John Punch, was sentenced to lifetime slavery for attempting to run away. This case also marked the disparate treatment of Africans as held by the Virginia County Court, where two white runaways received far lesser sentences.[16] After 1640, planters started to ignore the expiration of indentured contracts. They kept their servants as slaves for life. This was demonstrated by the case Johnson v. Parker. The court ruled that John Casor, an indentured servant, be returned to Johnson who claimed that Casor belonged to him for his life.[17][18] According to the 1860 U. S. census, 393,975 individuals, representing 8% of all US families, owned 3,950,528 slaves.[19] One-third of Southern families owned slaves.[20] Slavery in United States was legally abolished by Thirteenth Amendment to the United States Constitution in 1865.[21][unreliable source?]

Millions of people are still slaves in some parts of the world, mostly in South Asia and Africa. It is less common in the developed world because of better law enforcement, but it still happens there as well.[4] The ways in which it is done have changed. Today, slaves may work because of things like a high debt (for example, slaves have to work to pay off a debt). Many victims are told that their families will be harmed if they report the slave owners. Many slaves are forced to be domestic servants. In some cases, their families sell them to the slave owners. Some slaves have been trafficked from one part of the world to another. These people are illegally in their host country, and therefore do not report the abuse. Forced prostitution is a type of slavery. Another form of slavery still happening today is forced child labor. Some children have to work in mines or in plantations, or they have to fight wars as child soldiers, for no pay.

Some of the countries where there is still slavery are in Africa, the Middle East, and South Asia.[23] In summer 2007, 570 people were found to be slaves for brick makers in China.[24] They included 69 children.[25] The Chinese government made a force of 35,000 police check northern Chinese brick kilns for slaves, and sent lots of kiln supervisors and officials to prison and sentenced one kiln foreman to death for killing a worker who was a slave.[24]

In Mauritania, it is thought that up to 600,000 men, women and children, or 20% of the population, are slaves, and that many of them are used as bonded labour.[26][27] Slavery in Mauritania was made illegal in August 2007.[28] In Niger, there is also much slavery. A Nigerian study has found that more than 800,000 people are slaves, almost 8% of the population.[29][30][31] Child slavery has commonly been used when making cash crops and mining. According to the United States Department of State, more than 109,000 children were working on cocoa farms alone in Côte d'Ivoire (Ivory Coast) in 'the worst forms of child labour' in 2002.[32]

In November 2006, the International Labour Organization said that it would prosecute members of the junta that rules Myanmar (also called Burma) at the International Court of Justice for "Crimes against Humanity". This is because the military makes some citizens do forced labour.[33][34] The International Labour Organisation says that it thinks that about 800,000 people are forced to work this way.[35][36]

An agitation called Abolitionism against slavery began in Christian countries in the 18th century. First they abolished the slave trade so more people wouldn't become slaves. In 1833, the British Empire stopped slavery. Several other countries followed. In the United States, disagreement over slavery led to the American Civil War and the Emancipation Proclamation. In 1865, when the North won, all slaves were made free. Still more countries abolished slavery afterwards. Pedro II of Brazil abolished it in 1888. Forced labor however continued, either against the law or by debt peonage or other methods which the laws of the various countries did not count as slavery.

Severus Snape is a character from J.K. Rowling's fictional book series Harry Potter.
|
2 |
+
Snape is the Potions master at Hogwarts in the series. He is also known to be a Death Eater but after Voldemort started hunting James Potter and Lily J. Potter, the woman Snape had loved since he was a child, he asked Albus Dumbledore to find a safe place for the Potters to hide because he knew Voldemort wanted to kill their son, Harry Potter. As Dumbledore was not able to save the Potters, Snape's sorrow was extremely deep, he gained Dumbledore's trust. Snape was loyal to Dumbledore after this event. Snape killed Dumbledore in the sixth book on Dumbledore's request. Voldemort believed Snape killed him because Voldemort had planned Snape to do that. Snape had let it slip in the third book that Remus Lupin was a werewolf.

The last thing Snape's eyes ever saw were Lily's green eyes. Later, Harry Potter and Ginny Weasley named their youngest son after Albus Dumbledore and Severus Snape. Harry confesses to his son Albus Severus that Severus Snape was the bravest man he ever knew even though while still at school, Snape had been the teacher that Harry had hated the most because of Snape's bad behaviour towards Harry. Snape was so mean to Harry because of Harry's father, James Potter, that had bullied Snape while they were at Hogwarts. Snape was more than a cruel, heartless death eater but rather a brave and sincere victim to the perils of love in the reign of a power obsessed and heartless dictator.

Seville (Spanish: Sevilla) is a big city in the South of Spain, in Europe. A big river called the Guadalquivir River goes through Seville.
|
2 |
+
|
3 |

The city of Seville is the capital of the Spanish region called Andalusia and of the province of Sevilla. The people who live in the city are called Sevillanos and there are almost a million of them: 700,000.
|

|
5 |

A very old story says that the city was started by the famous hero of Greece, named Hercules. The Romans when they came to Spain gave it the Latin name of Hispalis. Over time this changed to be spelled in English as Seville. The Arab Moors took the city when they invaded the country, and you can still see a lot of the buildings they built during their 800-year stay in Spain (711-1492).

A banana is the common name for a type of fruit and also the name for the herbaceous plants that grow it. These plants belong to the genus Musa. They are native to the tropical region of southeast Asia.
|
4 |
+
|
5 |
+
It is thought that bananas were grown for food for the first time in Papua New Guinea.[1] Today, they are cultivated in tropical regions around the world.[2] Most banana plants are grown for their fruits, which botanically are a type of berry. Some are grown as ornamental plants, or for their fibres.
|
6 |
+
|
7 |
+
There are about 110 different species of banana. In popular culture and commerce, "banana" usually refers to the soft and sweet kind, also known as dessert bananas. Other kinds, or cultivars, of banana have a firmer, starchier fruit. Those are usually called plantains. Plantains are mostly used for cooking or fibre.
|
8 |
+
|
9 |
+
Other than being used as food, beer can be made by fermenting the juice of certain cultivars in Africa, known as beer bananas.[3] The ash of bananas can be used to make soap.[3] In Asia, bananas are often planted to provide shade to plants that like shade, for example coffee, cocoa, nutmeg or black pepper.[3] Because of this, banana plants can often be found in plantations of other crops.
|
10 |
+
|
11 |
+
The banana plant is the largest herbaceous flowering plant.[4] Banana plants are often mistaken for trees. Bananas have a false stem (called pseudostem), which is made by the lower part of the leaves. This pseudostem can grow to be two to eight meters tall. Each pseudostem grows from a corm. A pseudostem is able to produce a single bunch of bananas. After fruiting, the pseudostem dies and is replaced. When most bananas are ripe, they turn yellow or, sometimes, red. Unripe bananas are green.
|
12 |
+
|
13 |
+
Banana leaves grow in a spiral and may grow 2.7 metres (8.9 feet) long and 60 cm (2.0 ft) wide.[5] They are easily torn by the wind, which results in a familiar, frayed look.[6]
|
14 |
+
|
15 |
+
The banana fruits grow from a banana blossom in hanging clusters, also called a bunch or banana stem. The fruits grow in rows called tiers or hands. There can be as many as twenty fruits to a hand, and as many as twenty tiers in a bunch. A bunch usually weighs between 30 and 50 kilograms (65 to 110 pounds).
|
16 |
+
|
17 |
+
A single fruit weighs about 125 grams (4.4 ounces) on average; about three quarters of this is water.
|
18 |
+
|
19 |
+
Each banana (or finger) has a protective outer layer (called peel or skin). There is a fleshy part inside that readily spilts into three segments. It is the only known tri-segmented fruit in the world. Both the skin and inner part can be eaten. Western cultures generally eat the inside raw and throw away the skin. Some Asian cultures eat both the skin and the inside cooked.[7] Each fruit has many strings that run between the skin and the inner part.
|
20 |
+
|
21 |
+
Bananas have a lot of vitamin B6, vitamin C, and potassium.[8]
|
22 |
+
|
23 |
+
Bananas are grown in at least 107 countries.[9] The banana species growing in the wild have fruits with many hard, large seeds, but almost all bananas grown to be eaten have seedless fruits. Bananas are classified either as dessert bananas or as green cooking bananas. Almost all export bananas are of the dessert types. Only about ten to fifteen percent of all production is for export.[5][10] Dessert bananas change their color and usually turn yellow, when they are ripe; plantains and bananas generally used for cooking stay green. Certain bananas have other colors when ripe.
|
24 |
+
|
25 |
+
The countries that produce the most bananas include India, Brazil, China, Ecuador and the Philippines.[11] The top five countries that exported bananas were Ecuador, Costa Rica, the Philippines, Colombia and Guatemala.[12] The United States, the European Union and Japan buy the most bananas.[10] Bananas are among the most valuable agricultural export products; They provided about sixty percent of export earnings of Saint Lucia and about twelve percent of the Gross Domestic Product of the country, between 1994 and 1996.[10]

Some people are allergic to bananas. There are two basic forms of these allergies. The first is known as oral allergy syndrome. Within an hour of eating a banana, swelling starts inside the mouth or throat. This allergy is related to allergies caused by pollen, like that of the birch tree. The other is similar to latex allergies. It causes urticaria and potentially serious upper gastrointestinal symptoms.[13]

The fibre gained from the banana plant has been used to make textiles for a long time. In Japan, bananas have been grown to be used for clothing and in the house since at least the 13th century. In the Japanese system, the leaves and shoots are cut from the plant periodically to make sure they are soft. The harvested shoots must first be boiled in lye to prepare the fibres for the making of the yarn. These banana shoots produce fibres of varying degrees of softness. They can be used for yarns and textiles of different qualties, and for specific uses. For example, the outermost fibres of the shoots are the coarsest - they are good for tablecloths. The softest innermost fibres are desirable for kimono and kamishimo. This traditional Japanese banana cloth making process has many steps, all performed by hand.[14]
|
30 |
+
|
31 |
+
Another system is used in Nepal. There the trunk of the banana plant is harvested instead. Small pieces of this trunk are then softened. The fibres are extracted mechanically, bleached, and dried. They are then sent to the Kathmandu Valley, where high-end rugs are produced. These rugs have a texture and general qualities similar to that of silk. These banana fibre rugs are woven by traditional Nepalese hand-knotted methods.

A medium-sized banana will provide around 320-400 mg of potassium, which meets about 10% of your daily potassium needs. Potassium helps your body maintain a healthy heart and blood pressure. In addition, bananas are low in sodium. The low sodium and high potassium combination helps to control high blood pressure.
|
34 |
+
|
35 |

Banana fiber is also used to make banana paper. There are two different kinds of banana paper: paper made from the bark, and paper made from the fibre and from unused fruits.

Seychelles is an African country in the Indian Ocean. Its capital city is Victoria. The official languages are Creole, English, and French.
|
2 |
+
|
3 |
+
The country is to the east of the African continent. The islands of Madagascar and Mauritius lie to the south. The republic is made up of 115 islands. The biggest part of the population is a mix of freed slaves from the African Continent and Madagascar and European settlers. They make up about 90%. There are small minorities of immigrants from Europe, China and India. Most people are Roman Catholics, about 90% of them. About 8% are Protestants.
|
4 |
+
|
5 |
+
Other nearby island countries and territories include Zanzibar to the west, Mauritius, Rodrigues, Agalega and Réunion to the south, and Comoros and Mayotte to the southwest. Seychelles has an estimated population of 86,525. It is the smallest population of any African state.[4]
|
6 |
+
|
7 |
+
Seychelles is to the northeast of Madagascar and about 1,600 km (994 mi) east of Kenya. The number of islands in the archipelago is often given as 115 but the Constitution of the Republic of Seychelles lists 155.
|
8 |

|
9 |

According to the president of Nauru, the Seychelles has been ranked the ninth most endangered nation due to flooding from climate change.[5]

|

Some of the districts in Seychelles include: Anse Boileau, Takamaka and Cote D’Or.
|
12 |
+
|
13 |
+
Seychelles is divided into twenty-five administrative regions. Eight of the districts make up the capital of Seychelles. They are called Greater Victoria. Another 14 districts are considered the rural part of the main island of Mahé. There are two districts on Praslin and one on La Digue which also include satellite islands. The rest of the Outer Islands are not considered part of any district.

During the plantation era, cinnamon, vanilla, and copra were the main exports. In the 1960s, about 33% of the working population worked at plantations, and 20% worked in the public or government sector. In 1971, with the opening of Seychelles International Airport, tourism became a serious industry.

Like many fragile island ecosystems, the Seychelles had loss of biodiversity during early human history. This included the disappearance of most of the giant tortoises from the granitic islands. There was also the extinction of species such as the chestnut flanked white eye, the Seychelles Parakeet, the Seychelles Black Terrapin and the saltwater crocodile. However, extinctions were far fewer than on islands such as Mauritius or Hawaii. This was partly due to a shorter period of human occupation being only since 1770. The Seychelles today is known for success stories in protecting its flora and fauna. The rare Seychelles Black Parrot, the national bird of the country, is now protected.
|
22 |
+
|
23 |
+
The granitic islands of Seychelles are home to about 75 endemic plant species. There are a further 25 or so species in the Aldabra group. Particularly well-known is the Coco de Mer, a species of palm that grows only on the islands of Praslin and neighbouring Curieuse. The jellyfish tree is to be found in only a few locations on Mahe. This strange and ancient plant is in a genus of its own (Medusagynaceae). Other unique plant species include the Wright's Gardenia Rothmannia annae found only on Aride Island Special Reserve.
|
24 |

|
25 |

The freshwater crab genus Seychellum is endemic to the granitic Seychelles. There are a further 26 species of crabs and 5 species of hermit crabs that live on the islands.[6]
|
26 |

|
27 |

The Aldabra Giant Tortoise now lives on many of the islands of the Seychelles. The Aldabra population is the largest in the world. These unique reptiles can be found even in captive herds.
|
28 |
+
|
29 |
+
There are several unique varieties of orchids on the Islands.
|
30 |
+
|
31 |
+
The marine life around the islands, especially the more remote coral islands, can be spectacular. More than 1,000 species of fish have been recorded. Since the use of spearguns and dynamite for fishing was banned in the 1960s, the wildlife is unafraid of snorkelers and divers. Coral bleaching in 1998 has damaged most reefs, but some reefs show healthy recovery.
|
32 |
+
|
33 |

The main natural resources of the Seychelles are fish, copra, cinnamon, coconuts, salt and iron.

William Shakespeare (bapt. 26 April 1564 – 23 April 1616)[a] was an English playwright, poet, and actor. He wrote 39 plays (with about half of them considered comedies) and two long poems in his lifetime. He lived in Stratford-upon-Avon, in Warwickshire, England. His plays are still performed today. He is often quoted in modern writing.
|
4 |
+
|
5 |
+
By 1594 he was an actor in The Chamberlain's Men acting company.
|
6 |
+
|
7 |
+
His plays are of different kinds, or genres. There are histories, tragedies and comedies. These plays are among the best known in English literature and are studied in schools around the world. Shakespeare wrote his works between about 1590 and 1613. He is considered the first writer who wrote a tragicomedy. (A tragicomedy is a play that mixes comedy and tragedy, with a happy ending.)
|
8 |
+
|
9 |
+
Shakespeare's plays are written in poetic language. Many of the plays are set in strange, distant places and times. They are still popular today. The stories are often exciting, very funny (in the comedies), or very sad (in the tragedies) and make people want to know what happens to his characters. He says much about things that are still important today, like love, sadness, hope, pride, hatred, jealousy, and foolishness.
|
10 |
+
|
11 |
+
Shakespeare added new words and phrases to the English language. He also made some words more popular.[2] He created over 1,700 English words.[3]
|
12 |
+
|
13 |
+
He married Anne Hathaway, a woman eight years older than he was. He had three children, Susanna (married John Hall), Hamnet Shakespeare (died at the age of 11 due to unknown reasons) and Judith (married Thomas Quiney). By 1592 he had become an actor and was becoming well known as a writer of plays. At the time of his death in 1616, only some of his plays had been published in single editions. The plays were collected and published in 1623, seven years after he died.
|
14 |
+
There is proof that people in Shakespeare's time thought highly of him. After his death, even his rival Ben Jonson said,[4]
|
15 |
+
|
16 |
+
He was involved in the building of the Globe Theatre in 1599. It burned down a few years later. His plays are performed at a new Globe built nearby in 1997.
|
17 |
+
|
18 |
+
Although Shakespeare was married to a woman and fathered three children, Susanna, Hamnet and Judith, people have debated his sexuality. Some people, such as Peter Holland of the Shakespeare Institute at Birmingham University, have argued that Shakespeare was possibly bisexual because of some of the sonnets he wrote that were directed towards young men.[5]
|
19 |
+
|
20 |
+
About 150 years after Shakespeare died, some writers began to say that the work called "Shakespeare" were not really written by William Shakespeare. They had various reasons for saying this. For example, the person who wrote "Shakespeare" knew a lot about other countries (especially Italy and France), but William Shakespeare never left England.
|
21 |
+
Several other writers of "Shakespeare" have been suggested, such as Francis Bacon, Christopher Marlowe, and Edward de Vere, 17th Earl of Oxford. Most scholars believe that William Shakespeare did write the works that bear his name.[6]

Shanghai (Chinese: 上海, Shanghainese pronunciation: [zɑ̃.hɛ] (listen); Mandarin pronunciation: [ʂâŋ.xài] (listen)) is the biggest city in China and one of the world's largest cities. It had about 24,000,000 people in 2017. It is so big and important that it is a special province-level city ("municipality"), like Beijing, Tianjin, and Chongqing. Right now, it is the biggest port in the world.

The Mandarin Chinese name of Shanghai is Shànghǎi,[a] which is written as 上海 in Chinese characters. This name means "On-the-Sea" because Shanghai used to be next to the East China Sea. Today, dirt from the Yangtze River has made Pudong much bigger and downtown Shanghai is about 40 kilometers (25 mi) from the open sea. The city has become so big, though, that its government now controls other areas like Pudong and Fengxian that are still beside the sea.

Shanghai's name is a little simpler than most other Chinese cities' names, because it was a small fishing village for a long time. The short way to say its name in Chinese is still Hù[a] (沪). A hu was an old kind of fishing trap that was made with bamboo and nets. The people around Shanghai used to use them to catch fish and crabs in Suzhou Creek and other waterways.

Shanghai is at the mouth of the Yangtze River, where it meets the East China Sea in the middle of China's east coast. Downtown Shanghai is located just south of the place where Suzhou Creek meets the Huangpu River. This is about 20 kilometers (12 mi) southwest of where the Huangpu meets the Yangtze River. The area between downtown and the Yangtze used to be farmland and other cities like Wusong and Baoshan, but now Shanghai is so big that they are part of it.

For most of China's history, Shanghai was a small fishing village. The big cities nearby were Suzhou and Hangzhou. Under the Ming and Qing, Shanghai had a big city wall and started to grow.

Under the Ming and the Qing, people from other countries could only buy and sell things with China on an island near Guangzhou. The British began selling Indian drugs to pay for all the tea and other things they were buying from China. In the 1840s, China tried to stop them and the British started a war. To keep them from hurting Nanjing, the Chinese agreed to let them keep selling drugs. They also let the British start buying and selling things at four other cities, including Shanghai. Soon, parts of Shanghai were controlled by the UK, the US, and France. This control was ended by the Japanese during World War II.

The Holocaust, sometimes called The Shoah (Hebrew: השואה), was a genocide in which Nazi Germany systematically killed people during World War II. About six million Jews were killed,[a][13][14] as well as five million others that the Nazis claimed were inferior (mostly Slavs, communists, Romani/Roma people, people with disabilities, homosexuals, and Jehovah's Witnesses). These people were rounded up, put in ghettos, forced to work in concentration camps, and then killed in gas chambers.[15] Jews were forced to wear the yellow Star of David, a symbol of their religion.
|

+
|
3 |
+
There was hatred and persecution of Jews (anti-Semitism) in Europe for hundreds of years. Many people wrongly thought that all Jews became rich by stealing money from other people, such as Christians; that they did not like people other than their fellow Jews; and that they harmed children to use their blood for religious rituals (blood libel). These beliefs were not true, and were based on stereotypes and prejudices.
|
4 |
+
|
5 |
+
However these beliefs were popular in the German-speaking world and elsewhere in the late 1800s.
|
6 |
+
|

Adolf Hitler was born in Austria during this time, when many people disliked Jews. He may have been jealous of Jewish success in Austria. However, in a book he wrote called Mein Kampf ("My Struggle"), he said it was the Jews' fault that Germany and Austria lost World War I. He also wrote that Germany's economic problems were the Jews' fault. Many people agreed with Hitler’s ideas and supported him as the leader of the Nazi Party.[16][17]

Not all deaths were written down, so the exact numbers are not known. However various sources approximate:

Led by Hitler, the Nazis killed millions of Jews. They forced Jews to wear the golden Star of David on their upper bodies. Jews were rounded up by the thousands and crammed into trains that took them to concentration camps like Auschwitz as well as death camps. Most of the Jews killed in the Holocaust were not German. They were from Poland or the Soviet Union.
|
12 |
+
|
13 |
+
The Nazis killed millions of people, hundreds at a time, with poison gas in special rooms called gas chambers. They forced others to dig giant holes in the ground where, after days of hard work, Jews and other prisoners were shot, buried, and burned in a mass grave. The Nazis executed many others by shooting, stabbing, or beating them to death. Still others died in forced marches from one camp to another. Many other people died of starvation, diseases, and freezing to death because of the terrible conditions in the concentration camps.
|
14 |
+
|
15 |
+
On the other hand, there were people who saved Jews from the Holocaust, because they thought it was the right thing to do. Some of them were later given "Righteous Among the Nations" awards by Yad Vashem.
|
16 |
+
|
17 |
+
Some people say the Holocaust did not happen at all,[20] or was not as bad as historians say it was. This is called Holocaust denial. However, almost all historians agree that the Holocaust did happen and has been described correctly.[21] Many Holocaust deniers profess that the Nazis did not kill as many people as historians say. Instead, they claim many of these people died from disease or lack of food, usually in order to shift blame from the Nazis. These ideas have been disproven by historical accounts, eyewitness evidence, and documentary evidence from the Nazis themselves. Also many Jews were killed because Hitler ordered it. In some countries in Europe, including Germany,[22] it is against the law to say that the Holocaust never happened.[23]

A banana is the common name for a type of fruit and also the name for the herbaceous plants that grow it. These plants belong to the genus Musa. They are native to the tropical region of southeast Asia.
|
4 |
+
|
5 |
+
It is thought that bananas were grown for food for the first time in Papua New Guinea.[1] Today, they are cultivated in tropical regions around the world.[2] Most banana plants are grown for their fruits, which botanically are a type of berry. Some are grown as ornamental plants, or for their fibres.
|
6 |
+
|
7 |
+
There are about 110 different species of banana. In popular culture and commerce, "banana" usually refers to the soft and sweet kind, also known as dessert bananas. Other kinds, or cultivars, of banana have a firmer, starchier fruit. Those are usually called plantains. Plantains are mostly used for cooking or fibre.
|
8 |
+
|
9 |
+
Other than being used as food, beer can be made by fermenting the juice of certain cultivars in Africa, known as beer bananas.[3] The ash of bananas can be used to make soap.[3] In Asia, bananas are often planted to provide shade to plants that like shade, for example coffee, cocoa, nutmeg or black pepper.[3] Because of this, banana plants can often be found in plantations of other crops.
|
10 |
+
|
11 |
+
The banana plant is the largest herbaceous flowering plant.[4] Banana plants are often mistaken for trees. Bananas have a false stem (called pseudostem), which is made by the lower part of the leaves. This pseudostem can grow to be two to eight meters tall. Each pseudostem grows from a corm. A pseudostem is able to produce a single bunch of bananas. After fruiting, the pseudostem dies and is replaced. When most bananas are ripe, they turn yellow or, sometimes, red. Unripe bananas are green.
|
12 |
+
|
13 |
+
Banana leaves grow in a spiral and may grow 2.7 metres (8.9 feet) long and 60 cm (2.0 ft) wide.[5] They are easily torn by the wind, which results in a familiar, frayed look.[6]
|
14 |
+
|
15 |
+
The banana fruits grow from a banana blossom in hanging clusters, also called a bunch or banana stem. The fruits grow in rows called tiers or hands. There can be as many as twenty fruits to a hand, and as many as twenty tiers in a bunch. A bunch usually weighs between 30 and 50 kilograms (65 to 110 pounds).
|
16 |
+
|
17 |
+
A single fruit weighs about 125 grams (4.4 ounces) on average; about three quarters of this is water.
|
18 |
+
|
19 |
+
Each banana (or finger) has a protective outer layer (called peel or skin). There is a fleshy part inside that readily spilts into three segments. It is the only known tri-segmented fruit in the world. Both the skin and inner part can be eaten. Western cultures generally eat the inside raw and throw away the skin. Some Asian cultures eat both the skin and the inside cooked.[7] Each fruit has many strings that run between the skin and the inner part.
|
20 |
+
|
21 |
+
Bananas have a lot of vitamin B6, vitamin C, and potassium.[8]
|
22 |
+
|
23 |
+
Bananas are grown in at least 107 countries.[9] The banana species growing in the wild have fruits with many hard, large seeds, but almost all bananas grown to be eaten have seedless fruits. Bananas are classified either as dessert bananas or as green cooking bananas. Almost all export bananas are of the dessert types. Only about ten to fifteen percent of all production is for export.[5][10] Dessert bananas change their color and usually turn yellow, when they are ripe; plantains and bananas generally used for cooking stay green. Certain bananas have other colors when ripe.
|
24 |
+
|
25 |
+
The countries that produce the most bananas include India, Brazil, China, Ecuador and the Philippines.[11] The top five countries that exported bananas were Ecuador, Costa Rica, the Philippines, Colombia and Guatemala.[12] The United States, the European Union and Japan buy the most bananas.[10] Bananas are among the most valuable agricultural export products; They provided about sixty percent of export earnings of Saint Lucia and about twelve percent of the Gross Domestic Product of the country, between 1994 and 1996.[10]
|
26 |

|

Some people are allergic to bananas. There are two basic forms of these allergies. The first is known as oral allergy syndrome. Within an hour of eating a banana, swelling starts inside the mouth or throat. This allergy is related to allergies caused by pollen, like that of the birch tree. The other is similar to latex allergies. It causes urticaria and potentially serious upper gastrointestinal symptoms.[13]

The fibre gained from the banana plant has been used to make textiles for a long time. In Japan, bananas have been grown to be used for clothing and in the house since at least the 13th century. In the Japanese system, the leaves and shoots are cut from the plant periodically to make sure they are soft. The harvested shoots must first be boiled in lye to prepare the fibres for the making of the yarn. These banana shoots produce fibres of varying degrees of softness. They can be used for yarns and textiles of different qualties, and for specific uses. For example, the outermost fibres of the shoots are the coarsest - they are good for tablecloths. The softest innermost fibres are desirable for kimono and kamishimo. This traditional Japanese banana cloth making process has many steps, all performed by hand.[14]
|
30 |
+
|
31 |
+
Another system is used in Nepal. There the trunk of the banana plant is harvested instead. Small pieces of this trunk are then softened. The fibres are extracted mechanically, bleached, and dried. They are then sent to the Kathmandu Valley, where high-end rugs are produced. These rugs have a texture and general qualities similar to that of silk. These banana fibre rugs are woven by traditional Nepalese hand-knotted methods.

A medium-sized banana will provide around 320-400 mg of potassium, which meets about 10% of your daily potassium needs. Potassium helps your body maintain a healthy heart and blood pressure. In addition, bananas are low in sodium. The low sodium and high potassium combination helps to control high blood pressure.
|
34 |
+
|
35 |
+
Banana fiber is also used to make banana paper. There are two different kinds of banana paper: paper made from the bark, and paper made from the fibre and from unused fruits.

Sicily[p] is the largest island in the Mediterranean. Along with some smaller islands it is an autonomous region of Italy. The capital city of Sicily is Palermo. The population was about 5,087,000 (over 5 million) in 2004. Sicily is the biggest region in the nation of Italy.

Phoenician and Greek people colonized the island in the 8th Century BC and sometimes fought wars there. Carthage controlled most of the island until ancient Rome conquered it. In later centuries Saracens fought against the Byzantine Greeks, and Normans ruled it for a few centuries. Garibaldi in the Risorgimento conquered it and brought it into the Kingdom of Italy.

Acquired immunodeficiency syndrome or Acquired immune deficiency syndrome (AIDS) is a disease caused by a virus called HIV.
|
2 |
+
|
3 |
+
As of 2018, it is estimated that there are 39.7 million people worldwide infected with HIV.[1] The HIV pandemic is most severe in Sub-Saharan Africa. Over 60% of all people with HIV live in the region.
|
4 |
+
|
5 |
+
Many people with HIV do not know they have it. Because of this, the exact number of people with HIV is unknown.
|

Scientists believe the first human who got HIV was a person in Africa in the early 1900’s. It infected only a small amount of people (disease not recognised), until it then turned into an epidemic reported to have started in New York (USA) in 1981. It then very quickly started spreading to other countries. This happened when Simian Immunodeficiency Virus (SIV) went from apes or chimpanzees to humans. This virus probably crossed to humans when a hunter came into contact with monkey blood while cutting up monkeys to eat.[2] Research in October 2014 shows that the virus started in Kinshasa during the 1920s.[2] It was quickly spread by unprotected sex, dirty needles used by intravenous drug users, and it then made its way into the medical blood supply .[2] Some people described the spread of the disease as a sexidemic (widespread).[3]

Not everyone who has HIV has AIDS. When people first get HIV, they can be healthy for years. A person is diagnosed as having AIDS when he or she gets specific types of illnesses or gets sick in certain ways due to their HIV. Once a person's HIV progresses to (or turns into) AIDS, the person will continue to have AIDS for the rest of their life. While there are many treatments for HIV/AIDS, at this point there is no cure.
|
10 |
+
|
11 |
+
If someone has HIV they are called HIV-positive.
|
12 |
+
|

Someone has AIDS if they have HIV and either:
|

+
|

If a person gets an "AIDS-defining illness," this is usually a sign that the person has AIDS. Healthy people do not get these illnesses, because a healthy immune system is strong enough to fight off these diseases. Because of this, getting an AIDS-defining illness is a sign that a person's immune system is seriously damaged. In a person with HIV, getting an AIDS-defining illness signals that the HIV has damaged the immune system badly enough that the person now has AIDS.
|
16 |
+
|
17 |
+
Some AIDS defining illnesses are:
|
18 |
+
|
19 |
+
HIV can be spread by some body fluids that have HIV in them:[4]
|
20 |
+
|
21 |
+
This means a person can get HIV by:[4]
|
22 |
+
|
23 |
+
HIV is NOT spread by:[4]
|
24 |
+
|
25 |
+
There are medicines that help people with AIDS. These are called antiretroviral medicines (or antiretrovirals.) Anti- means against. HIV is a retrovirus. So antiretroviral means it fights retroviruses.
|
26 |
+
|
27 |
+
Antiretrovirals cannot cure AIDS. This means they cannot make all of the virus leave a person's body. But they can make people with AIDS more healthy. Antiretrovirals help people fight the HIV virus. This makes their immune systems work better. So antiretrovirals are a treatment but not a cure for HIV.
|
28 |
+
|
29 |
+
People with HIV/AIDS who take antiretroviral medicines live longer. They live longer without getting AIDS defining illnesses. But after a long time, the HIV virus learns how to fight the antiretrovirals. The HIV virus is not killed by this medicine. HIV becomes resistant to the medicine. Then the resistant HIV hurts the immune system and the person may get AIDS.
|
30 |
+
|
31 |
+
Sometimes when HIV is resistant to one medicine, another medicine can be used. To make less resistance happen, people with AIDS take more than one medicine at the same time. They may take 2–4 medicines at once. This is sometimes called a cocktail or AIDS cocktail.
|
32 |
+
|
33 |
+
When HIV gets resistant to one medicine, this is changed to another medicine. So the AIDS cocktail that people with AIDS take changes over time. But after a long time, the HIV learns to be resistant to many drugs. This is called multi-drug-resistant (acronym MDR) HIV. After the HIV in a person has MDR-HIV there may be no more medicines to treat them. So scientists keep trying to find new medicines to fight HIV.
|
34 |
+
The five most important HIV medicines are:
|
35 |
+
|
36 |
+
Many people who die of AIDS, especially in Africa, leave behind children who are still alive, and may need help. These children are called AIDS orphans.
|
37 |
+
|
38 |
+
There are many ways people fight the AIDS epidemic.
|
39 |
+
|
40 |
+
The most important way to stop HIV/AIDS is education. People can get HIV from the exchange of bodily fluids and from sharing needles. Children can also get HIV from their mothers (when they grow inside pregnant mothers and when they drink breast milk.)
|
41 |
+
Sex is one way to get HIV. If people use condoms when they have sex, there is a much smaller chance of catching HIV.
|
42 |
+
|
43 |
+
A person can also get HIV by sharing needles. This means using a needle that has not been cleaned after someone else has used it. Some people who take illegal drugs like heroin and cocaine take these drugs by needle. Some of these people share needles. If one person has HIV and he shares his needles, he can give HIV to other people. But if people have clean needles or if they know how to clean needles, they do not get HIV as much.
|
44 |
+
|
45 |
+
Many people do not know that condoms and clean needles help stop HIV. They may not even know that sharing needles and sex with someone who has HIV can make them get HIV. Even if people know about condoms and clean needles, they may not have condoms and clean needles.
|
46 |
+
|
47 |
+
There are some people who do not want people to know about condoms or clean needles. They believe that if people know about condoms and have condoms they will have more sex. They believe that if people have clean needles they will use illegal drugs more. Many of these people think this because of their religion. For example, the Catholic church does not want people to have or use condoms.[5] They do not want people to have condoms because they do not think people should have sex unless they are married. They also think that married people should not use condoms, because they believe that if people have sex, they should be prepared to accept a possible pregnancy.
|
48 |
+
|
49 |
+
Scientists who study (look at and learn about) people who use condoms, see that if teenagers (children 13–19) learn about condoms (and other birth control) they have less unsafe sex. Scientists see that learning about these things does not make teenagers start having sex earlier. The teenagers also have safer sex. Safer sex means doing things (like wearing condoms) to try not to get pregnant or get sexually transmitted diseases (STDs or STIs) like HIV, gonorrhea, and syphilis. Using a condom works very well for keeping people from getting pregnant or getting STDs if people know how to use a condom the right way.[1] [2]
|
50 |
+
|
51 |
+
Scientists have also learned that if a city has a needle exchange program it will have fewer people who use illegal drugs. Needle exchange programs are where people can come in and trade dirty needles for clean needles. This means that if they use drugs they will be more safe. But needle exchange programs do more than give people clean needles. They teach people about drugs. If people want to stop using drugs, they help them.
|
52 |
+
|
53 |
+
The best way to stop HIV is thought to be a vaccine. There is no vaccine for HIV yet. Many scientists are looking for an HIV vaccine. Even one that protected some people from HIV would save millions of people's lives.
|
54 |
+
|
55 |
+
Some people think that HIV is not the cause of AIDS. They dispute the connection between HIV and AIDS,[6] the existence of HIV itself, or the validity of HIV testing and treatment methods.[7][8] These claims, known as "AIDS denialism", are rejected by the scientific community.[9] However, they have had a significant impact, particularly in South Africa. There the government's official embrace of AIDS denialism (1999–2005) was responsible for its weak response to that country's AIDS epidemic. It has been blamed for hundreds of thousands of avoidable deaths and HIV infections.[10][11][12]
|
56 |
+
|
57 |
+
Some conspiracy theories have been put about. Operation INFEKTION was a worldwide Soviet active measures operation to spread the claim that the United States had created HIV/AIDS. Surveys show that a significant number of people believed – and continue to believe – in such claims.[13]

The Age of Enlightenment was an 18th century cultural movement in Europe. It was most popular in France, where its leaders included philosophers like Voltaire and Denis Diderot. Diderot helped spread the Enlightenment's ideas by writing the Encyclopédie, the first big encyclopedia that was available to everyone. The Enlightenment grew partly out of the earlier scientific revolution and the ideas of René Descartes.

|
3 |

The Enlightenment's most important idea was that all people can reason and think for themselves. Because of this, people should not automatically believe what an authority says. People do not even have to believe what churches teach or what priests say. This was a very new idea at the time.
|

|
5 |
+
Another important idea was that a society is best when everyone works together to create it. Even people with very little power or money should have the same rights as the rich and powerful to help create the society they live in.[1] The nobility should not have special rights or privileges any more.
|

These were very new ideas at the time. They were also dangerous thoughts for the people in power. Many Enlightenment philosophers were put in prison or were forced to leave their home countries.

Many of the Founding Fathers of the United States believed the Enlightenment's ideas. For example, the idea that a government's job is to benefit all of a country's people not just the people in power was very important to them. They made this idea about a government "for the people" one of the most important parts of the new United States Constitution and the new American government they created.

In some countries, kings and queens took some of the Enlightenment's ideas and made changes to their governments. However, they still kept power for themselves. These kings and queens were called "enlightened despots." Examples include Catherine the Great of Russia, Frederick the Great of Prussia, and Gustav III of Sweden.

During the Age of Enlightenment, as more and more people began to use reason, some began to disagree with the idea that God created the world. This caused conflicts - and, later, war.

Many ideas that are important today were created during the Enlightenment. Examples of these ideas include:

The Enlightenment's ideas about thinking with reason, having personal freedoms, and not having to follow the Catholic Church were important in creating capitalism and socialism.

Important people in the Enlightenment came from many different countries and shared ideas in many different ways. Some of the best-known Enlightenment figures, organized by home country, are:

Sierra Leone is a country in West Africa. Its capital is Freetown. The official language is English.
|
4 |
+
|
5 |
+
The country was first made as a place where freed slaves could live. From 1991 until 2000, there was a civil war in Sierra Leone between rebels and the government. The war is now over. Sierra Leone is known for its blood diamonds. These were mined and sold during the civil war. This was in order to buy the weapons for the civil war.[2]
|
6 |
+
|
7 |
+
There are 71,740 square kilometres of land in Sierra; In terms of land area it is similar in size to Ireland.
|
8 |
+
|
9 |
+
Sierra Leone has relied on mining, especially diamonds, for its economic base. The country is among the largest producers of titanium and bauxite, and a major producer of gold. The country has one of the world's largest deposits of rutile. Sierra Leone is also home to the third largest natural harbour in the world. Shipping from all over the globe goes to Freetown's famous Queen Elizabeth II Quay. Despite this natural wealth, 70% of its people live in poverty.[3]

|
23 |
+
December and January are prefably the best times to visit Sierra Leone as temperatures and humidity are much lower and reasonable due to the hammattan breeze from the sahara desert, although afternoon temperatures can still climb up to 40 °C and above, the hammattan breeze stops it from getting too humid, even though it will still be hot, humidity would be can be lowered down to 39% meaning you'll sweat less during this time than you would when the climate goes back to its original state, so therefore the heat would be more endurable especially around coastal areas.
|
24 |
+
|
25 |
+
When the hammattan breeze has lowered the heat and the humidity to its base, the highest average daily temperature in December and January will only reach a maximum of 31 °C (88 °F) and night time temperatures will be 24 °C (75 °F), although it can seldomly drop down to 21 °C (70 °F) at night, and sometimes in the morning which is the lowest the temperature can get. During this time, humidity is 70% & it is pleasantly warm and enjoyable.
|
26 |
+
|
27 |
+
The rainy season from May-November, average temperatures are 27 °C (81 °F) - 29 °C (84 °F) with humidity 95% - 100%. Some days when it doesn't rain, temperatures can climb up to 32 °C (90 °F) and humidity can be moderate around 75%.

Subtraction is the arithmetic operation for finding the difference between two numbers. The special names of the numbers in a subtraction expression are, minuend - subtrahend = difference. The expression 7 - 4 = 3 can be spoken as "seven minus four equals three," "seven take away four leaves three," or "four from seven leaves three."
|
2 |
+
|
3 |
+
If the minuend is less than the subtrahend, the difference will be a negative number. For example, 17 - 25 = ( -8 ). We can say this as, "Seventeen minus twenty-five equals negative eight." This is how cash registers determine the change you receive when you pay with more money than your purchase costs.

Chert is a type of rock that includes flint and agate. It sometimes has fossils in it, usually shells. It is a sedimentary rock, and it is very hard. It is made from quartz. People used chert to make arrow heads because it was hard and sharp when broken. The color of chertz is usually white or gray, but can be red, yellow or dark grey. If there is a lot of iron oxide in the chert it can be dark red; this type of chert is called "jasper."[1]

Silicon Valley is the southern part of the San Francisco Bay Area in California in the United States. The term originally meant the innovators and manufacturers of silicon chip who worked here, but now means all the high tech businesses in the area. Even though it's not truly a valley, it is a term for the high-tech sector generally.

Silicon Valley includes the northern part of Santa Clara Valley and adjacent communities in the southern parts of the San Francisco Peninsula and East Bay. It reaches from Menlo Park (on the Peninsula) and the Fremont/Newark area in the East Bay down to San Jose.

The term Silicon Valley was coined by journalist Don Hoefler in 1971. He used it as the title of a series of articles "Silicon Valley USA" in a weekly trade newspaper Electronic News which started with the January 11, 1971 issue. Valley refers to the Santa Clara Valley, located at the southern end of San Francisco Bay, while Silicon refers to the high concentration of semiconductor and computer-related industries in the area. These and similar technology firms slowly replaced the orchards which gave the area its initial nickname, the Valley of Heart's Delight.

The San Francisco Bay Area had long been a major site of U.S. Navy work, as well as the site of the Navy's large research airfield at Moffett Field. A number of technology firms had set up shop in the area around Moffett to serve the Navy. When the Navy moved most of its West Coast operations to San Diego, NASA took over portions of Moffett for aeronautics research. Many of the original companies stayed, while new ones moved in. The immediate area was soon filled with aerospace firms.

However, there was almost no civilian "high-tech" industry in the area. Although there were a number of excellent schools in the area, graduating students almost always moved east or south (that is, to Los Angeles County) to find work. This was particularly annoying to Frederick Terman, a professor at Stanford University. He decided that a vast area of unused Stanford land was perfect for real estate development, and set up a program to encourage students to stay in the area by enabling them to easily find venture capital. One of the major success stories of the program was that it convinced two students to stay in the area, William Hewlett and David Packard. In 1939, they founded Hewlett-Packard in Packard's garage, which would go on to be one of the first "high tech" firms in the area that was not directly related to NASA or the U.S. Navy.

Simón Bolívar (1783 - 1830) was a Venezuelan military and political leader. He was born in Caracas, Venezuela. He liberated many countries from Spain in South America. Those countries included Venezuela, Colombia, Ecuador, Peru, and Bolivia. For a few years he was president of Gran Colombia, a country that no longer exists. The country Bolivia is named after Bolívar.

White people felt ignored because Spaniards were sent by their governor, and resented wealthy mixed heritage people who could “buy” whiteness. The creoles started calling themselves Americans and not Spaniards to demonstrate that they wanted independence. In 1808, Napoleon conquered Spain, and made his brother, Joseph Bonaparte the new king. The colonies in Latin America rebelled because they said they were loyal to the old king, Charles IV of Spain and not Napoleon.

On September 6th 1815 Simón Bolívar wrote a letter from Jamaica. He explained the causes and reasons why all of South America or parts of it should be independent (free from Spain's ruling). Simón Bolívar was tired of how Venezuela and other countries were treated like slaves and how they were not free. He said “We have been harassed by a conduct which has not only deprived us of our rights but has kept us in a sort of permanent infancy with regard to public affairs.” He kept saying in the Jamaica letter why it's important to be free. “We are still in a position lower than slavery, and therefore it is more difficult for us to rise to the enjoyment of freedom.” This means they could not even enjoy freedom. "Because successes have been partial and spasmodic, we must not lose faith. We are young in the ways of almost all the arts and sciences, although, in a certain manner, we are old in the ways of civilized society."

Crossing plains on August 7, they encountered the royalists and won the battle in Boyacá on August 10. Bolívar then occupied Boyoca, Colombia. Bolivar won the fight of Carabobo in June 1821, and after that Caracas fell. A few days later and Venezuela was free of the Spanish royalists, then Bolívar went South and conquered Quito. On July 27, 1822 Simón Bolívar and José de San Martín met in the Guayaquil Conference. Bolivar came in as a military leader. Bolivar and San Martin went back to Europe where they both had a meeting. They were preparing to march across the Andes to Peru to defeat the Spanish royalists in August of 1824. Bolivar launched his campaign and soon he won a small but important battle at Junin.

Bolivar’s legacy is that he helped many of the Latin American countries achieve independence. People called him "El Liberator" because he freed the people. Some people hated him because they thought he was a traitor, and he was going to be a dictator.

White people felt ignored because Spaniards were sent by their governor, and resented wealthy mixed heritage people who could “buy” whiteness. The creoles started calling themselves Americans and not Spaniards to demonstrate that they wanted independence. In 1808, Napoleon conquered Spain, and made his brother, Joseph Bonaparte the new king. The colonies in Latin America rebelled because they said they were loyal to the old king, Charles IV of Spain and not Napoleon.

On September 6th 1815 Simón Bolívar wrote a letter from Jamaica. He explained the causes and reasons why all of South America or parts of it should be independent (free from Spain's ruling). Simón Bolívar was tired of how Venezuela and other countries were treated like slaves and how they were not free. He said “We have been harassed by a conduct which has not only deprived us of our rights but has kept us in a sort of permanent infancy with regard to public affairs.” He kept saying in the Jamaica letter why it's important to be free. “We are still in a position lower than slavery, and therefore it is more difficult for us to rise to the enjoyment of freedom.” This means they could not even enjoy freedom. "Because successes have been partial and spasmodic, we must not lose faith. We are young in the ways of almost all the arts and sciences, although, in a certain manner, we are old in the ways of civilized society."
