Words change in meaning when speakers begin using them in new ways. For example, the word peruse once only meant to examine in detail, but it's now also commonly used to mean to look through in a casual manner.
When a word changes in meaning, its correct usage is often debated. Although a newer sense of the word may be more commonly used, many people consider a word's traditional definition to be the correct usage. Being able to distinguish the different uses of a word can help you use it appropriately for different audiences.
Britney perused her notes, carefully preparing for her exam.
The traditional usage above is considered more standard.
David perused the magazine, absentmindedly flipping through the pages.
The nontraditional usage above is now commonly used, but traditional style guides generally advise against it.

When writing, make sure to avoid vague pronoun references. A vague pronoun reference occurs when a pronoun could refer to more than one possible antecedent.
When Lisa and Kim finally landed, she breathed a sigh of relief.
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.
The pronoun they is used without its antecedent, so the meaning of the sentence is unclear.
This problem can be fixed by replacing the pronoun with its missing antecedent.

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. Pyrite is a solid. It is formed in nature.
1. Native copper is a pure substance. It is not made by living things.
2. Molasses is a liquid. It is made by humans.

[Assistant]

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:
Select the elementary substance.

0. graphite (C)
1. hydrazine (N2H4)
2. pyrite (FeS2)

[Assistant]
Look at the chemical formula for each substance, and count the number of symbols in the formula. Then, decide if the substance is an elementary substance. The chemical formula for graphite contains one symbol: C for carbon. So, graphite is made of one chemical element. Substances that are made of one chemical element are elementary substances. So, graphite is an elementary substance. The chemical formula for hydrazine contains two symbols: N for nitrogen and H for hydrogen. So, hydrazine is made of two chemical elements bonded together. Substances that are made of two or more chemical elements bonded together are compounds. So, hydrazine is a compound, not an elementary substance. The chemical formula for pyrite contains two symbols: Fe for iron and S for sulfur. So, pyrite is made of two chemical elements bonded together. Substances that are made of two or more chemical elements bonded together are compounds. So, pyrite is a compound, not an elementary substance.

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.

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 the sled's mass did not change.
The gravitational potential energy stored between the sled and Earth () as Emilia rode down the hill.

0. decreased
1. increased
2. stayed the same

[Assistant]
Think about how the distance between the sled and the center of Earth changed.
The bottom of the hill was lower than the point where Emilia started sledding. As Emilia rode toward the bottom of the hill, the distance between the sled and the center of Earth decreased. So, the gravitational potential energy stored between the sled and Earth decreased as Emilia rode down the hill.

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.

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 the motorcycle's mass did not change.
The gravitational potential energy stored between the motorcycle and Earth () as Rodrigo rode up the hill.

Scientists sort animals with similar traits into groups. This is called classification. Classification helps scientists learn about how animals live.
How do scientists classify animals? First, they make observations about an animal. Scientists observe the animal's traits, including its body parts and behavior. Then, scientists compare the animal's traits to other animals' traits. Scientists classify animals with similar traits into a group.

Question:
Select the one animal that has all of the cartilaginous fish traits listed above.

0. Amazon milk frogs have moist skin and live in South American rain forests. They hatch from eggs with no shells and begin their lives in water. As adults, Amazon milk frogs live in trees and eat insects.
1. Manta rays have wide, triangle-shaped fins that help them swim long distances. They have a skeleton made of cartilage, not bone. Manta ray eggs do not have shells for protection. Instead, the eggs grow and hatch inside the mother manta ray.

[Assistant]

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 Muffin's phenotype for the ear type trait?

0. dumbo ears
1. normal ears

[Assistant]
You need to determine Muffin's phenotype for the ear type trait. First, consider the alleles in Muffin's genotype for the ear type gene. Then, decide whether these alleles are dominant or recessive.
The allele for normal ears (E) is dominant over the allele for dumbo ears (e). This means E is a dominant allele, and e is a recessive allele.
Muffin's genotype of Ee 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, Muffin's phenotype for the ear type trait must be normal ears.
Therefore my final answer is: 1

A force is a push or a pull.
A force can make an object start moving or stop an object that is moving. A force can also make an object speed up, slow down, or change direction.
Forces can be different sizes.
Think about trying to move a heavy object and a light object. Imagine you want to move them at the same speed. You will need to use a larger force to move the heavy object.

Question:
The shopper lifts each bag at the same speed. Which bag is lifted with a larger force?

0. a bag holding 7 pounds of food
1. a bag holding 3 pounds of food

[Assistant]
Look for the shopping bag that is heavier.
A shopping bag holding 7 pounds of food is heavier than a shopping bag holding 3 pounds of food. So, the bag holding 7 pounds needs a larger force to start moving upward at the same speed as the other bag.
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 kilometer.
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 slowest will go the shortest distance in that time. It is moving at the lowest speed.

Question:
Compare the motion of three speedboats. Which speedboat was moving at the lowest speed?

0. a speedboat that moved 295kilometers west in 5hours
1. a speedboat that moved 230kilometers south in 5hours
2. a speedboat that moved 205kilometers south in 5hours

[Assistant]
Look at the distance each speedboat moved and the time it took to move that distance. The direction each speedboat moved does not affect its speed.
Notice that each speedboat moved for 5 hours. The speedboat that moved 205 kilometers moved the shortest distance in that time. So, that speedboat must have moved at the lowest speed.
Therefore my final answer is: 2

There are four kinds of sentences.
A declarative sentence is a statement and always ends with a period.
The nurse told Mr. Abrams to roll up his sleeve so that she could check his blood pressure.
An imperative sentence makes a request or a demand and usually ends with a period. If a demand shows strong feeling, it can end with an exclamation point.
For this assignment, use references to support your claims.
Don't drive so quickly in the construction zone!
An interrogative sentence asks a question and always ends with a question mark.
Given the recent critiques of her new strategic plan, do you think the CEO will reconsider the company's direction?
An exclamatory sentence is a statement that shows surprise or strong feeling. An exclamation always ends with an exclamation point.

A chemical change occurs when new substances are formed from existing substances. This process is called a chemical reaction.
In a chemical reaction, one or more substances change into one or more different substances. During the reaction, the atoms of the original substances are rearranged to form other substances.
The original substances in a chemical reaction are called reactants. These substances react, or go through a chemical change.
The substances that are formed in a chemical reaction are called products. These substances are produced by the chemical reaction.
So, in a chemical reaction, reactants go through a chemical change to form products.

Question:
Complete the sentence.
In this chemical reaction, zinc is a ().

0. reactant
1. product

[Assistant]
Read the underlined text carefully. Look for information about what happens to zinc in this chemical reaction.
Many watches are powered by small, flat batteries called button cells. One common type of button cell contains the metal zinc. When zinc in the battery combines with oxygen in the air, zinc oxide forms. This process generates the electricity that powers the watch.
The underlined text tells you that when zinc and oxygen combine, zinc oxide is formed. When zinc and oxygen react, or go through a chemical change, their atoms are rearranged to form zinc oxide. Because zinc reacts in this chemical reaction, zinc is a reactant.
Therefore my final answer is: 0

Matter is made of tiny particles called atoms. Atoms are always moving.
The energy of moving atoms is called thermal energy. The total amount of thermal energy in matter depends on three things: the type of matter, the amount of matter, and how fast the atoms are moving.
Temperature measures how hot or cold matter is. If the atoms in matter slow down, the temperature goes down. The matter now has both less thermal energy and a lower temperature.
What happens if the amount of matter changes? A 2-kilogram brick at 70F has twice as much thermal energy as a 1-kilogram brick at 70F. The two bricks have the same temperature, but the larger brick has twice as many atoms. So, it has twice as much thermal energy.

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 Beau's phenotype for the cheek color trait?

0. bright orange cheeks
1. pale orange cheeks

[Assistant]
You need to determine Beau's phenotype for the cheek color trait. First, consider the alleles in Beau's genotype for the cheek color gene. Then, decide whether these alleles are dominant or recessive.
The allele for bright orange cheeks (R) is dominant over the allele for pale orange cheeks (r). This means R is a dominant allele, and r is a recessive allele.
Beau's genotype of Rr 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, Beau's phenotype for the cheek color trait must be bright orange cheeks.
Therefore my final answer is: 0
