Organisms, including people, have both inherited and acquired traits. Inherited and acquired traits are gained in different ways.
Inherited traits are passed down from biological parents to their offspring through genes. Genes are pieces of hereditary material that contain the instructions that affect inherited traits. Offspring receive their genes, and therefore gain their inherited traits, from their biological parents. Inherited traits do not need to be learned.
Acquired traits are gained during a person's life. Some acquired traits, such as riding a bicycle, are gained by learning. Other acquired traits, such as scars, are caused by the environment. Parents do not pass acquired traits down to their offspring.

Question:
What information supports the conclusion that Dirk acquired this trait?

0. Dirk's brother has scars on both of his knees.
1. Dirk's scar is on his left knee. His mother also has a scar on her left knee.
2. Dirk's scar was caused by an accident. He cut his leg when he fell off his skateboard.

The pronoun she could refer to either Lisa or Kim, so the meaning of the sentence is unclear.
Vague pronoun references can be corrected in one of two ways:
1. Replace the pronoun with its correct antecedent:
When Lisa and Kim finally landed, Lisa breathed a sigh of relief.
2. Rewrite the sentence:
Lisa breathed a sigh of relief when she and Kim finally landed.
A vague pronoun reference also occurs when they, them, their, theirs, it, or its is used without its antecedent.
They say that this nail polish dries in less than five minutes.

An object's speed tells you how fast the object is moving. Speed depends on both distance and time.
Distance tells you how far the object has moved. One unit used to measure distance is the mile.
Time tells you how long the object has spent moving. One unit used to measure time is the hour.
Think about objects moving for the same amount of time. The object that is moving the fastest will go the farthest distance in that time. It is moving at the highest speed.

Question:
Compare the motion of three sailboats. Which sailboat was moving at the highest speed?

0. a sailboat that moved 15miles north in 5hours
1. a sailboat that moved 40miles north in 5hours
2. a sailboat that moved 45miles west in 5hours

[Assistant]
Look at the distance each sailboat moved and the time it took to move that distance. The direction each sailboat moved does not affect its speed.
Notice that each sailboat moved for 5 hours. The sailboat that moved 45 miles moved the farthest distance in that time. So, that sailboat must have moved at the highest speed.
Therefore my final answer is: 2

Minerals are the building blocks of rocks. A rock can be made of one or more minerals.
Minerals and rocks have the following properties:
Property | Mineral | Rock
It is a solid. | Yes | Yes
It is formed in nature. | Yes | Yes
It is not made by organisms. | Yes | Yes
It is a pure substance. | Yes | No
It has a fixed crystal structure. | Yes | No
You can use these properties to tell whether a substance is a mineral, a rock, or neither.
Look closely at the last three properties:
Minerals and rocks are not made by organisms.
Organisms make their own body parts. For example, snails and clams make their shells. Because they are made by organisms, body parts cannot be  minerals or rocks.
Humans are organisms too. So, substances that humans make by hand or in factories are not minerals or rocks.
A mineral is a pure substance, but a rock is not.
A pure substance is made of only one type of matter.  Minerals are pure substances, but rocks are not. Instead, all rocks are mixtures.
A mineral has a fixed crystal structure, but a rock does not.
The crystal structure of a substance tells you how the atoms or molecules in the substance are arranged. Different types of minerals have different crystal structures, but all minerals have a fixed crystal structure. This means that the atoms and molecules in different pieces of the same type of mineral are always arranged the same way.
However, rocks do not have a fixed crystal structure. So, the arrangement of atoms or molecules in different pieces of the same type of rock may be different!

Question:
Select the one substance that is not a mineral.

0. Native gold is not made by living things. It is a pure substance.
1. Diamond is formed in nature. It is a solid.
2. Paper is made by humans. It is not a pure substance.

[Assistant]
Compare the properties of each substance to the properties of minerals. Select the substance whose properties do not match those of minerals.
Paper is made by humans. But minerals are not made by living things.
Paper is not a pure substance. But all minerals are pure substances.
So, paper is not a mineral.
Diamond is a mineral.
Native gold is a mineral.

Gravitational potential energy is stored between any two objects. So, for every object on or near Earth, there is gravitational potential energy stored between the object and Earth.
The amount of gravitational potential energy stored between an object and Earth depends on the mass of the object. The amount of gravitational potential energy also depends on the distance between the object and the center of Earth. This distance increases when the object moves higher and decreases when the object moves lower.
If the distance between an object and the center of Earth changes, the gravitational potential energy stored between the object and Earth will change. The table below shows how this change can happen.
When an object's mass stays the same and its distance from the center of Earth... | Gravitational potential energy stored between the object and Earth...
increases | increases
decreases | decreases
stays the same | stays the same

Question:
Complete the statement. Assume that Logan's mass did not change.
The gravitational potential energy stored between Logan and Earth () as he hiked toward the summit.

All organisms have pieces of hereditary material called genes, which are passed from parents to offspring. Genes contain instructions for building the parts of an organism. An organism's genes affect its observable traits, including its appearance, its behavior, and which diseases it may have. Genes may have different alleles, or forms, that can cause different versions of a trait.
For example, flower color is a trait in pea plants. The gene for this trait has two possible alleles. Each allele is represented by an uppercase or lowercase letter. The allele F is for purple flowers, and the allele f is for white flowers. Each pea plant has two alleles for the flower color geneone allele inherited from each parent.
An organism's genotype for a gene is its combination of alleles for that gene. So, a pea plant may have a genotype of FF, Ff, or ff for the flower color gene.
An organism's phenotype for a trait is its observable version of that trait, which depends on the organism's combination of alleles. A pea plant may have a phenotype of purple flowers or white flowers for the flower color trait.
Some traits, like flower color in pea plants, are controlled by a single gene. Most plants and animals have a genotype made up of two alleles for these traits. These two alleles determine whether an organism is homozygous or heterozygous for the gene.
An organism with two identical alleles for a gene is homozygous for that gene. A pea plant with the genotype FF or ff is homozygous for the flower color gene.
An organism with two different alleles for a gene is heterozygous for that gene. A pea plant with the genotype Ff is heterozygous for the flower color gene.
The types of alleles in an organism's genotype determine the organism's phenotype. Some alleles have types called dominant and recessive. These two types can cause different versions of a trait to appear as the organism's phenotype.
A dominant allele causes its version of the trait to appear even when the organism also has a recessive allele for the gene. In pea plants, the F allele, which causes purple flowers, is dominant over the f allele. A pea plant with at least one F allele will have the F allele's version of the flower color trait. So, a plant with the genotype FF or Ff will have purple flowers.
A recessive allele causes its version of the trait to appear only when the organism does not have any dominant alleles for the gene. In pea plants, the f allele, which causes white flowers, is recessive to the F allele. A pea plant with only f alleles will have the f allele's version of the flower color trait. So, a plant with the genotype ff will have white flowers.

Question:
Based on this information, what is Malia's phenotype for the Thomsen disease trait?

0. not having Thomsen disease
1. having Thomsen disease

[Assistant]
You need to determine Malia's phenotype for the Thomsen disease trait. First, consider the alleles in Malia's genotype for the Thomsen disease gene. Then, decide whether these alleles are dominant or recessive.
The allele for having Thomsen disease (M) is dominant over the allele for not having Thomsen disease (m). This means M is a dominant allele, and m is a recessive allele.
Malia's genotype of Mm has one dominant allele and one recessive allele. An organism with at least one dominant allele for a gene will have the dominant allele's version of the trait. So, Malia's phenotype for the Thomsen disease trait must be having Thomsen disease.

People around the world live in three main kinds of places: urban areas, suburban areas, and rural areas.
An urban area is a city. It has many people and businesses. The buildings are close to each other. The buildings are often tall and have many floors. Since there are so many people, traffic is usually bad. People will walk or take the bus, train, or subway to avoid traffic.
A suburban area, or suburb, is near a city. It is quieter and less crowded than an urban area. People usually live in houses with yards. Most people drive to get places.
A rural area is less crowded than both urban and suburban areas. Houses are much more spread out. People usually have to drive to get places. People in rural areas often live on farms or ranches.
Some places, like small towns, don't really fit into any of the types. A small town does not have as many people as an urban area, but it has more people than a rural area. It is not near a city, so it is not called a suburb.

Question:
In which place would you be more likely to drive to see your neighbors?

0. a rural area
1. an urban area

[Assistant]
You would be more likely to drive to see your neighbors in a rural area. In urban areas, your neighbors live right next to you. In rural areas, houses are farther apart.

So, a plant with the genotype ff will have white flowers.

Question:
Based on this information, what is Jasmine's phenotype for the fur color trait?

0. white fur
1. orange fur

[Assistant]
Jasmine's genotype for the fur color gene is ff. Jasmine's genotype of ff has only f alleles. The f allele is for white fur. So, Jasmine's phenotype for the fur color trait must be white fur.
To check this answer, consider whether Jasmine's alleles are dominant or recessive. The allele for white fur (f) is recessive to the allele for orange fur (F). This means F is a dominant allele, and f is a recessive allele.
Jasmine's genotype of ff has only recessive alleles. An organism with only recessive alleles for a gene will have the recessive allele's version of the trait. So, Jasmine's phenotype for the fur color trait must be white fur.

All organisms have pieces of hereditary material called genes, which are passed from parents to offspring. Genes contain instructions for building the parts of an organism. An organism's genes affect its observable traits, including its appearance, its behavior, and which diseases it may have. Genes may have different alleles, or forms, that can cause different versions of a trait.
For example, flower color is a trait in pea plants. The gene for this trait has two possible alleles. Each allele is represented by an uppercase or lowercase letter. The allele F is for purple flowers, and the allele f is for white flowers. Each pea plant has two alleles for the flower color geneone allele inherited from each parent.
An organism's genotype for a gene is its combination of alleles for that gene. So, a pea plant may have a genotype of FF, Ff, or ff for the flower color gene.
An organism's phenotype for a trait is its observable version of that trait, which depends on the organism's combination of alleles. A pea plant may have a phenotype of purple flowers or white flowers for the flower color trait.
Some traits, like flower color in pea plants, are controlled by a single gene. Most plants and animals have a genotype made up of two alleles for these traits. These two alleles determine whether an organism is homozygous or heterozygous for the gene.
An organism with two identical alleles for a gene is homozygous for that gene. A pea plant with the genotype FF or ff is homozygous for the flower color gene.
An organism with two different alleles for a gene is heterozygous for that gene. A pea plant with the genotype Ff is heterozygous for the flower color gene.
The types of alleles in an organism's genotype determine the organism's phenotype. Some alleles have types called dominant and recessive. These two types can cause different versions of a trait to appear as the organism's phenotype.
A dominant allele causes its version of the trait to appear even when the organism also has a recessive allele for the gene. In pea plants, the F allele, which causes purple flowers, is dominant over the f allele. A pea plant with at least one F allele will have the F allele's version of the flower color trait. So, a plant with the genotype FF or Ff will have purple flowers.
A recessive allele causes its version of the trait to appear only when the organism does not have any dominant alleles for the gene. In pea plants, the f allele, which causes white flowers, is recessive to the F allele. A pea plant with only f alleles will have the f allele's version of the flower color trait. So, a plant with the genotype ff will have white flowers.

Question:
Based on this information, what is Cupcake's phenotype for the eye color trait?

0. brown eyes
1. red eyes

[Assistant]
Cupcake's genotype for the eye color gene is EE. Cupcake's genotype of EE has only E allelles. The E allele is for brown eyes. So, Cupcake's phenotype for the eye color trait must be brown eyes.
To check this answer, consider whether Cupcake's alleles are dominant or recessive. The allele for brown eyes (E) is dominant over the allele for red eyes (e). This means E is a dominant allele, and e is a recessive allele.
Cupcake's genotype of EE has two dominant alleles. An organism with at least one dominant allele for a gene will have the dominant allele's version of the trait. So, Cupcake's phenotype for the eye color trait must be brown eyes.
Therefore my final answer is: 0

To stay alive, animal cells must get water and oxygen. Animal cells also produce carbon dioxide, a waste that must be removed. An animal's respiratory and circulatory systems work together to do these jobs.
An animal's respiratory system is made up of organs that work together to bring in oxygen gas from the environment. The respiratory system also removes carbon dioxide gas from the animal's body. Some animals have lungs to exchange oxygen and carbon dioxide with the air. Other animals have gills to exchange oxygen and carbon dioxide with water.
An animal's circulatory system is made up of organs that work together to move blood through its body. The heart pumps blood through blood vessels throughout the body. As blood moves through blood vessels, it delivers oxygen, nutrients from food, and water to cells. Blood also absorbs waste, including carbon dioxide. When the blood is pumped into the lungs or gills, it releases carbon dioxide and absorbs oxygen.

Question:
Which job does the circulatory system do?

0. It brings oxygen to cells.
1. It breaks down food into small pieces.

[Assistant]
The circulatory system brings oxygen, nutrients, and water to cells. It also helps remove carbon dioxide waste.
The circulatory system does not break down food into small pieces. This job is done by the digestive system. After the digestive system breaks down food, blood vessels in the intestines absorb the nutrients from the food. The blood then carries the nutrients to cells throughout the body.
Therefore my final answer is: 0

An object's speed tells you how fast the object is moving. Speed depends on both distance and time.
Distance tells you how far the object has moved. One unit used to measure distance is the mile.
Time tells you how long the object has spent moving. One unit used to measure time is the hour.
Think about objects moving for the same amount of time. The object that is moving the fastest will go the farthest distance in that time. It is moving at the highest speed.

Question:
Compare the motion of three ships. Which ship was moving at the highest speed?

0. a ship that moved 215miles north in 10hours
1. a ship that moved 355miles east in 10hours
2. a ship that moved 365miles north in 10hours

[Assistant]
Look at the distance each ship moved and the time it took to move that distance. The direction each ship moved does not affect its speed.
Notice that each ship moved for 10 hours. The ship that moved 365 miles moved the farthest distance in that time. So, that ship must have moved at the highest speed.
Therefore my final answer is: 2

Every substance around you is made of one or more chemical elements, or types of atoms. Substances that are made of only one chemical element are elementary substances. Substances that are made of two or more chemical elements bonded together are compounds.
Every chemical element is represented by its own symbol. For some elements, the symbol is one capital letter. For other elements, the symbol is one capital letter and one lowercase letter. For example, the symbol for the element fluorine is F, and the symbol for the element beryllium is Be.
The symbol for each element in a substance is shown in the substance's chemical formula.
An elementary substance is represented by a chemical formula that contains only one symbol.
The symbol may be followed by a subscript. A subscript is text that is smaller and placed lower than the normal line of text. A subscript is included when the atoms in the elementary substance are bonded to form molecules. The subscript tells you the number of atoms in each molecule.
For example, the chemical formula for the elementary substance oxygen is O2. The formula has a subscript of 2. This subscript tells you that there are two atoms in the molecule represented by this chemical formula.
The chemical element represented by the symbol O is also called oxygen. So, the formula O2 tells you that each molecule of O2 contains two oxygen atoms.
A compound is represented by a chemical formula that contains multiple symbols.
For example, in the compound beryllium fluoride, there is one beryllium atom for every two fluorine atoms. This combination is shown in the compound's chemical formula, BeF2. In the formula, the symbol Be represents one beryllium atom. The symbol F followed by the subscript 2 represents two fluorine atoms.

Think about two objects moving for the same amount of time. The object that is moving slower will go a shorter distance in that time. It is moving at a lower speed.

Question:
Compare the motion of two speedboats. Which speedboat was moving at a lower speed?

0. a speedboat that moved 460miles in 10hours
1. a speedboat that moved 555miles in 10hours

[Assistant]
Look at the distance each speedboat moved and the time it took to move that distance.
One speedboat moved 460 miles in 10 hours.
The other speedboat moved 555 miles in 10 hours.
Notice that each speedboat spent the same amount of time moving. The speedboat that moved 460 miles moved a shorter distance in that time. So, that speedboat must have moved at a lower speed.
Therefore my final answer is: 0

All organisms have pieces of hereditary material called genes, which are passed from parents to offspring. Genes contain instructions for building the parts of an organism. An organism's genes affect its observable traits, including its appearance, its behavior, and which diseases it may have. Genes may have different alleles, or forms, that can cause different versions of a trait.
For example, flower color is a trait in pea plants. The gene for this trait has two possible alleles. Each allele is represented by an uppercase or lowercase letter. The allele F is for purple flowers, and the allele f is for white flowers. Each pea plant has two alleles for the flower color geneone allele inherited from each parent.
An organism's genotype for a gene is its combination of alleles for that gene. So, a pea plant may have a genotype of FF, Ff, or ff for the flower color gene.
An organism's phenotype for a trait is its observable version of that trait, which depends on the organism's combination of alleles. A pea plant may have a phenotype of purple flowers or white flowers for the flower color trait.

Question:
Based on this information, what is Briar's genotype for the fur texture gene?

Every substance around you is made of one or more chemical elements, or types of atoms. Substances that are made of only one chemical element are elementary substances. Substances that are made of two or more chemical elements bonded together are compounds.
Every chemical element is represented by its own symbol. For some elements, the symbol is one capital letter. For other elements, the symbol is one capital letter and one lowercase letter. For example, the symbol for the element fluorine is F, and the symbol for the element beryllium is Be.
The symbol for each element in a substance is shown in the substance's chemical formula.
An elementary substance is represented by a chemical formula that contains only one symbol.
The symbol may be followed by a subscript. A subscript is text that is smaller and placed lower than the normal line of text. A subscript is included when the atoms in the elementary substance are bonded to form molecules. The subscript tells you the number of atoms in each molecule.
For example, the chemical formula for the elementary substance oxygen is O2. The formula has a subscript of 2. This subscript tells you that there are two atoms in the molecule represented by this chemical formula.
The chemical element represented by the symbol O is also called oxygen. So, the formula O2 tells you that each molecule of O2 contains two oxygen atoms.
A compound is represented by a chemical formula that contains multiple symbols.
For example, in the compound beryllium fluoride, there is one beryllium atom for every two fluorine atoms. This combination is shown in the compound's chemical formula, BeF2. In the formula, the symbol Be represents one beryllium atom. The symbol F followed by the subscript 2 represents two fluorine atoms.

Question:
Complete the statement.
Hydrazine is ().

0. an elementary substance
