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.

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 Cookie's genotype for the body hair gene?

0. BB
1. a hairy body

[Assistant]
An organism's genotype for a gene is its combination of alleles for that gene. Cookie has two alleles for a hairy body (B). So, Cookie's genotype for the body hair gene is BB.

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 water balloon's mass did not change.
The gravitational potential energy stored between the water balloon and Earth () as the water balloon fell toward Jeremiah.

0. stayed the same
1. decreased
2. increased

[Assistant]
Think about how the distance between the water balloon and the center of Earth changed.
Jeremiah was lower than the balcony. As the water balloon fell toward Jeremiah, the distance between the water balloon and the center of Earth decreased. So, the gravitational potential energy stored between the water balloon and Earth decreased as the water balloon fell toward Jeremiah.

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.

Question:

There is a surplus if there is too much for sale at a given price.
There is a shortage if there is not enough for sale at a given price.
Surpluses and shortages usually happen when people who are selling goods or services charge too much or too little.
When the price is too high, consumers will not want to buy much of the good or service. The quantity demanded will be less than the quantity supplied. So, there will be a surplus.
When the price is too low, too many consumers will want to buy the good or service. The quantity demanded will be more than the quantity supplied. So, there will be a shortage.

Question:
Is there a surplus or a shortage of cupcakes?

0. surplus
1. shortage

[Assistant]
At the current price, there are not enough cupcakes for sale. There are 75 cupcakes for sale, but 200 people want to buy one.
So, there is a shortage of cupcakes.
Therefore my final answer is: 1

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.

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.

Chemical changes and physical changes are two common ways matter can change.
In a chemical change, the type of matter changes. The types of matter before and after a chemical change are always different.
Burning a piece of paper is a chemical change. When paper gets hot enough, it reacts with oxygen in the air and burns. The paper and oxygen change into ash and smoke.
In a physical change, the type of matter stays the same. The types of matter before and after a physical change are always the same.
Cutting a piece of paper is a physical change. The cut pieces are still made of paper.
A change of state is a type of physical change. For example, ice melting is a physical change. Ice and liquid water are made of the same type of matter: water.

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. phosphine (PH3)
1. zirconium (Zr)
2. potassium nitrate (KNO3)

[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 phosphine contains two symbols: P for phosphorus and H for hydrogen. So, phosphine is made of two chemical elements bonded together. Substances that are made of two or more chemical elements bonded together are compounds. So, phosphine is a compound, not an elementary substance. The chemical formula for zirconium contains one symbol: Zr. So, zirconium is made of one chemical element. Substances that are made of one chemical element are elementary substances. So, zirconium is an elementary substance. The chemical formula for potassium nitrate contains three symbols: K for potassium, N for nitrogen, and O for oxygen. So, potassium nitrate is made of three chemical elements bonded together. Substances that are made of two or more chemical elements bonded together are compounds. So, potassium nitrate is a compound, not an elementary substance.
Therefore my final answer is: 1

Solid and liquid are states of matter. Matter is anything that takes up space. Matter can come in different states, or forms.
When matter is a solid, it has a shape of its own.
Some solids can be bent or broken easily. Others are hard to bend or break.
A glass cup is a solid. A sock is also a solid.
When matter is a liquid, it takes the shape of its container.
Think about pouring a liquid from a cup into a bottle. The shape of the liquid is different in the cup than in the bottle. But the liquid still takes up the same amount of space.
Juice is a liquid. Honey is also a liquid.

Question:
Select the solid.

[User]
There are more than 100 different chemical elements, or types of atoms. Chemical elements make up all of the substances around you.
A substance may be composed of one chemical element or multiple chemical elements. Substances that are composed of only one chemical element are elementary substances. Substances that are composed of multiple chemical elements bonded together are compounds.
Every chemical element is represented by its own atomic symbol. An atomic symbol may consist of one capital letter, or it may consist of a capital letter followed by a lowercase letter. For example, the atomic symbol for the chemical element fluorine is F, and the atomic symbol for the chemical element beryllium is Be.
The atomic symbol for each chemical 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 atomic symbol.
The atomic symbol in a chemical formula may be followed by a small number written lower than the symbol. This number is called a subscript. A subscript is included when the atoms in the elementary substance are bonded to form molecules. The subscript shows how many atoms are in each molecule.
For example, the chemical formula for the elementary substance oxygen, O2, has a subscript of 2. This subscript shows that the atomic symbol O represents two atoms. The elementary substance O2 and the chemical element represented by the atomic symbol O are both named oxygen. So, the formula tells you that each molecule of O2 contains two oxygen atoms.
A compound is represented by a chemical formula that contains multiple atomic symbols.
The chemical elements in a compound are bonded together in a fixed ratio. This ratio is shown in a compound's chemical formula.
For example, in the compound beryllium fluoride, there is one beryllium atom for every two fluorine atoms. So, the ratio of beryllium atoms to fluorine atoms is 1 to 2. This ratio is shown in the chemical formula for beryllium fluoride, BeF2. There is no subscript following the atomic symbol Be because that symbol represents one atom. The subscript 2 follows the atomic symbol F to show that the symbol represents two atoms.

Question:
Complete the statement.
Calcium oxide is ().

0. a compound
1. an elementary substance

[Assistant]
You can tell whether calcium oxide is an elementary substance or a compound by counting the number of atomic symbols in its chemical formula. An atomic symbol consists of either one capital letter or a capital letter followed by one or two lowercase letters.
The chemical formula for calcium oxide, CaO, contains two atomic symbols: Ca for calcium and O for oxygen. So, the formula tells you that calcium oxide is composed of two chemical elements bonded together.
Since calcium oxide is composed of multiple chemical elements bonded together, calcium oxide is a compound.
Therefore my final answer is: 0

Chemical changes and physical changes are two common ways matter can change.
In a chemical change, the type of matter changes. The types of matter before and after a chemical change are always different.
Burning a piece of paper is a chemical change. When paper gets hot enough, it reacts with oxygen in the air and burns. The paper and oxygen change into ash and smoke.
In a physical change, the type of matter stays the same. The types of matter before and after a physical change are always the same.
Cutting a piece of paper is a physical change. The cut pieces are still made of paper.
A change of state is a type of physical change. For example, ice melting is a physical change. Ice and liquid water are made of the same type of matter: water.

Question:
Complete the sentence.
A piece of avocado turning brown is a ().

0. physical change
1. chemical change

[Assistant]
A piece of avocado turning brown is a chemical change. The avocado reacts with oxygen in the air to form a different type of matter.
If you scrape off the brown part of the avocado, the inside will still be green. The inside hasn't touched the air. So the chemical change hasn't happened to that part of the avocado.

Measurements are written with both a number and a unit. The unit comes after the number. The unit shows what the number means.
Imagine being told that a pencil is 16 long. You might be thinking, 16 what? Is the pencil 16 centimeters long? 16 meters? 16 kilometers?
The number 16 on its own does not give you much information about the length of the pencil. That is because the units are missing.
Now look at the drawing of the pencil and the ruler. The ruler shows that the units are centimeters. So, the length of the pencil is 16 centimeters.
There are 100 centimeters in 1 meter. So, 1 centimeter is much shorter than 1 meter.
There are 1,000 meters in 1 kilometer. So, 1 meter is much shorter than 1 kilometer.

All solids, liquids, and gases are made of matter. Matter is made up of tiny particles that are always moving. The energy from the motion of these particles is called thermal energy.
Temperature measures how hot or cold matter is. If the particles in matter slow down, the temperature goes down. The matter now has both less thermal energy and a lower temperature.

Question:
Which object has the least thermal energy?

0. a crayon at a temperature of 26C
1. a crayon at a temperature of 22C
2. a crayon at a temperature of 30C

[User]
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 Zach's mass did not change.
The gravitational potential energy stored between Zach and Earth () as he rode the escalator.

0. decreased
1. increased
2. stayed the same

[Assistant]
Think about how the distance between Zach and the center of Earth changed.
The second floor is higher than the first floor. As he rode the escalator toward the second floor, the distance between Zach and the center of Earth increased. So, the gravitational potential energy stored between Zach and Earth increased as he rode the escalator.

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 mammal traits listed above.

0. Red salamanders do not have lungs! They can breathe through their moist, smooth skin. Adult red salamanders live near rivers or ponds. They lay eggs with no shells under rocks or logs. The baby red salamanders live underwater.
1. Female cats feed their offspring milk. Adult cats have fur and hunt small animals for food. Cats can see better in the dark than people can! Seeing in the dark helps cats hunt their prey.

[Assistant]
To decide if an animal is part of a group, look at the traits of the group.
Mammals have the following traits:
They feed their offspring milk.
They have fur or hair.
Compare each animal's traits to the group's traits. Select the animal with traits similar to the group's traits.
A red salamander has the following traits:
It spends part of its life in water and part on land.
It has moist skin.
It makes eggs with no shells.
A red salamander does not have all of the traits of a mammal. A red salamander is an amphibian.

Living things are made up of four main groups of carbon-based molecules called organic compounds. One of these groups is carbohydrates. The other three groups are lipids, proteins, and nucleic acids.
All carbohydrates are made up of the same three chemical elements: carbon, hydrogen, and oxygen. But carbohydrate molecules can come in different forms. The smallest carbohydrates are called simple sugars. Simple sugars can be linked together in long chains to make larger carbohydrates, called complex carbohydrates.
Carbohydrates can also have different functions. An important function of carbohydrates is to provide the primary source of energy for cells. Cells can quickly break down many types of carbohydrates to release energy, so these carbohydrates provide energy for cells' immediate use. Carbohydrates can also form cell structures. One complex carbohydrate, called cellulose, forms the cell walls in plant cells. Cellulose helps to give plants structure and make them strong.

Question:
Which of the following is a primary function of carbohydrates?

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 this plant's phenotype for the flower form trait?

0. double flowers
1. single flowers

[Assistant]
The rose plant's genotype for the flower form gene is FF. The rose plant's genotype of FF has only F allelles. The F allele is for double flowers. So, the rose plant's phenotype for the flower form trait must be double flowers.
To check this answer, consider whether the rose plant's alleles are dominant or recessive. The allele for double flowers (F) is dominant over the allele for single flowers (f). This means F is a dominant allele, and f is a recessive allele.
The rose plant's genotype of FF 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, the rose plant's phenotype for the flower form trait must be double flowers.
Therefore my final answer is: 0
