Organisms, including people, have both inherited and acquired traits. Inherited and acquired traits are gained in different ways.
Inherited traits are passed down through families. Children gain these traits from their 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. Children do not inherit their parents' acquired traits.

Question:
Is the following trait inherited or acquired?
Evan knows how to type.

0. acquired
1. inherited

[Assistant]
People are not born knowing how to type. Instead, many people learn how to type. So, typing is an acquired trait.

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 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 bowhead whales. Which bowhead whale was moving at a lower speed?

0. a bowhead whale that moved 45kilometers in 10hours
1. a bowhead whale that moved 65kilometers in 10hours

[Assistant]
Look at the distance each bowhead whale moved and the time it took to move that distance.
One bowhead whale moved 45 kilometers in 10 hours.
The other bowhead whale moved 65 kilometers in 10 hours.
Notice that each bowhead whale spent the same amount of time moving. The bowhead whale that moved 45 kilometers moved a shorter distance in that time. So, that bowhead whale must have moved at a lower speed.
Therefore my final answer is: 0

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 trucks begin to move at the same speed. Which truck needs a larger force to start moving?

0. a mail truck carrying 250 pounds of mail
1. a mail truck carrying 350 pounds of mail

[Assistant]
Look for the mail truck that is heavier.
A mail truck carrying 350 pounds of mail is heavier than a mail truck carrying 250 pounds of mail. So, the mail truck carrying 350 pounds needs a larger force to start moving at the same speed as the other mail truck.
Therefore my final answer is: 1

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. Plagioclase is not made by living things. It is a solid.
1. Glue is made in a factory. It is not a pure substance.
2. Graphite is formed in nature. It is 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.
Graphite is a mineral.
Glue is not a pure substance. But all minerals are pure substances.
Glue is made in a factory. But all minerals are formed in nature.
So, glue is not a mineral.
Plagioclase is a mineral.

Matter is made of very small particles called atoms. Atoms can be linked together by chemical bonds. When two or more atoms link together, they form a molecule.
In a chemical change, the chemical bonds in the molecules break. The atoms then link together to form new molecules. The types of molecules in matter before and after a chemical change are always different.
Burning a piece of paper is a chemical change. As paper burns, paper molecules react with oxygen molecules in the air. This reaction breaks the chemical bonds in the molecules. The atoms then relink and form different molecules. For example, carbon dioxide molecules are created when paper burns.
In a physical change, chemical bonds do not break. The types of molecules in matter before and after a physical change are always the same.
A change of state is a type of physical change. For example, water vaporizing is a physical change. Liquid water and water vapor are made of the same type of matter: water.

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 Sidney 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 Sidney started sledding. As Sidney 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 Sidney rode down the hill.
Therefore my final answer is: 0

Climate is the pattern of weather in a certain place. For example, summer temperatures in New York are usually higher than winter temperatures.

Question:
Does this passage describe the weather or the climate?
Where Audrey lives, winter is the rainiest season of the year.

0. climate
1. weather

[Assistant]
Read the text carefully.
Where Audrey lives, winter is the rainiest season of the year.
This passage tells you about the usual precipitation where Audrey lives. It does not describe what the weather is like on a particular day. So, this passage describes the climate.

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 Booster's phenotype for the horns trait?

0. having horns
1. not having horns

[Assistant]
Booster's genotype for the horns gene is hh. Booster's genotype of hh has only h alleles. The h allele is for having horns. So, Booster's phenotype for the horns trait must be having horns.
To check this answer, consider whether Booster's alleles are dominant or recessive. The allele for having horns (h) is recessive to the allele for not having horns (H). This means H is a dominant allele, and h is a recessive allele.
Booster's genotype of hh has only recessive alleles. An organism with only recessive alleles for a gene will have the recessive allele's version of the trait. So, Booster's phenotype for the horns trait must be having horns.
Therefore my final answer is: 0


[User]
Organisms, including people, have both inherited and acquired traits. Inherited and acquired traits are gained in different ways.
Inherited traits are passed down through families. Children gain these traits from their 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. Children do not inherit their parents' acquired traits.

Question:
Is the following trait inherited or acquired?
Raymond plays baseball.

0. inherited
1. acquired

[Assistant]
People are not born knowing how to play baseball. Instead, some people learn how to play baseball. Playing the sport takes practice. So, playing baseball is an acquired trait.
Therefore my final answer is: 1

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.

Formal writing is used for essays, business letters, and reports. The following types of informal language should be avoided in formal writing:
Type | Examples
slang | cool, awesome
idioms | knock your socks off
conversational language | gonna, kinda, yeah
abbreviated language | ASAP, FYI
overly simple or imprecise language | he got some stuff at the store
contractions | can't, won't
Contractions are not as informal as the other types, but they should be used sparingly in formal writing.
Compare the following sentences. The first is informal. The second is formal.
Informal: Yeah, ostriches can't fly, but they're awesome runners.
Formal: Though ostriches are flightless, they are remarkably adept runners.

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 move faster, the temperature goes up. The matter now has both more thermal energy and a higher 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.

Question:
Which wax candle has a higher temperature?

0. the wax candle with less thermal energy

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. Gypsum is a solid. It is not made by living things.
1. Native gold is a pure substance. It is not made by living things.
2. Brass is made in a factory. It is a solid.

[Assistant]
Compare the properties of each substance to the properties of minerals. Select the substance whose properties do not match those of minerals.
Native gold is a mineral.
Gypsum is a mineral.
Brass is made in a factory. But all minerals are formed in nature.
So, brass is not a mineral.

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 Fieval's phenotype for the fur color trait?

0. brown fur
1. black fur

[Assistant]
You need to determine Fieval's phenotype for the fur color trait. First, consider the alleles in Fieval's genotype for the fur color gene. Then, decide whether these alleles are dominant or recessive.
The allele for brown fur (f) is recessive to the allele for black fur (F). This means F is a dominant allele, and f is a recessive allele.
Fieval's genotype of Ff 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, Fieval's phenotype for the fur color trait must be black fur.

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

0. pale orange cheeks
1. bright orange cheeks

[Assistant]
You need to determine Tweety's phenotype for the cheek color trait. First, consider the alleles in Tweety'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.
Tweety'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, Tweety's phenotype for the cheek color trait must be bright orange cheeks.

Matter is made of very small particles called atoms. Atoms can be linked together by chemical bonds. When two or more atoms link together, they form a molecule.
In a chemical change, the chemical bonds in the molecules break. The atoms then link together to form new molecules. The types of molecules in matter before and after a chemical change are always different.
Burning a piece of paper is a chemical change. As paper burns, paper molecules react with oxygen molecules in the air. This reaction breaks the chemical bonds in the molecules. The atoms then relink and form different molecules. For example, carbon dioxide molecules are created when paper burns.
In a physical change, chemical bonds do not break. The types of molecules in matter before and after a physical change are always the same.
A change of state is a type of physical change. For example, water vaporizing is a physical change. Liquid water and water vapor are made of the same type of matter: water.

Question:
Complete the sentence.

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 Mabel acquired this trait?

0. Mabel's sister has a bruise from falling on her elbow.
1. Mabel's scar was caused by an accident. She cut her arm when she fell off her bicycle.

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.
