According to Newton's third law, for every force, there is an equal and opposite force. This means that if one object is applying a force on a second object, the second object must also be applying a force on the first object, but in the opposite direction.
For example, if your hand is pushing down on a table, the table is also pushing up on your hand. Or, if you are pulling forward on a rope, the rope is also pulling back on you.

Question:
According to Newton's third law, what other force must be happening?

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 Quincy acquired this 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 faster will go a farther distance in that time. It is moving at a higher speed.

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 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.

Question:
Which metal paper clip has less thermal energy?

0. the colder metal paper clip

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 Squirt's phenotype for the tail spots trait?

0. a spotted tail
1. an unspotted tail

[Assistant]
You need to determine Squirt's phenotype for the tail spots trait. First, consider the alleles in Squirt's genotype for the tail spots gene. Then, decide whether these alleles are dominant or recessive.
The allele for a spotted tail (I) is dominant over the allele for an unspotted tail (i). This means I is a dominant allele, and i is a recessive allele.
Squirt's genotype of Ii 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, Squirt's phenotype for the tail spots trait must be a spotted tail.

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.

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 Holly's phenotype for the whisker type trait?

0. straight whiskers
1. curved whiskers

[Assistant]
You need to determine Holly's phenotype for the whisker type trait. First, consider the alleles in Holly's genotype for the whisker type gene. Then, decide whether these alleles are dominant or recessive.
The allele for curved whiskers (h) is recessive to the allele for straight whiskers (H). This means H is a dominant allele, and h is a recessive allele.
Holly's genotype of Hh 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, Holly's phenotype for the whisker type trait must be straight whiskers.
Therefore my final answer is: 0

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.

Measurements are written with both a number and a unit. The unit comes after the number. The unit shows what the number means.
Volume is a measurement of how much space something takes up.
There are many different units of volume. When you are using customary units, volume may be written in units of fluid ounces, cups, or gallons.
As the diagram shows, there are 8 fluid ounces in 1 cup and 16 cups in 1 gallon. So, 1 fluid ounce is less than 1 cup and much less than 1 gallon.
A glass of milk has a volume of about 8 fluid ounces, or 1 cup. A jug of milk has a volume of 1 gallon.

Question:
What is the volume of a bowl of soup?

0. 8 gallons

1. a movement demanding that the Catholic Church change some of its practices
2. a period when people asked Protestant churches to reform their teachings
3. a conflict between Protestants and people who separated from the Catholic Church

[Assistant]
The Protestant Reformation was a movement demanding that the Catholic Church reform, or change, some of its practices. Catholic leaders were asked to reform, or change, what they were teaching and how they led the Catholic community. Choice "a period when people asked Protestant churches to reform their teachings" is incorrect. The Reformation was a period when people asked the Catholic Church to reform. Choice "a conflict between Protestants and people who separated from the Catholic Church" is incorrect. The people who left the Catholic Church were not in conflict with Protestants. They were Protestants. Choice "a war fought between Catholics in northern and western Europe" is incorrect. Before the Reformation, most people in northern and western Europe were Catholics, but they were not fighting with each other during this time.

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:
Each bus takes the same amount of time to stop. Which school bus needs a larger force to come to a stop?

0. a school bus carrying 700 pounds
1. a school bus carrying 500 pounds

[Assistant]
Look for the school bus that is heavier.
A school bus carrying 700 pounds is heavier than a school bus carrying 500 pounds. So, the school bus carrying 700 pounds needs a larger force to come to a stop in the same amount of time as the other bus.
Therefore my final answer is: 0

Organisms that carry out photosynthesis are called photosynthetic organisms. During photosynthesis, these organisms use light energy, carbon dioxide, and water to produce sugars and oxygen.
Photosynthetic organisms also often have the following characteristics:
They are producers, which are organisms that make their own food inside their cells. Because producers make their own food, they typically do not eat other organisms.
Their cells contain chloroplasts, which are cell structures where photosynthesis occurs.
Their chloroplasts often contain a green substance called chlorophyll. Chlorophyll captures light energy from the Sun to power photosynthesis.
They use the sugars they produce during photosynthesis as food. This food provides energy that helps the organisms live, grow, and reproduce.

Question:
Use the evidence in the text to select the photosynthetic organism.

0. Javan green magpies get their green color from the food they eat, which includes insects and lizards.
1. Bee orchid leaves are green because they contain chlorophyll. Chlorophyll captures energy from sunlight.

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.

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.
Making whipped cream is a ().

0. chemical change
1. physical change

[Assistant]
Making whipped cream is a physical change. Whipped cream is a mixture of cream and air. But making a mixture does not form a different type of matter.
As cream is whipped, its molecules begin to stick together. But the bonds between the atoms in the molecules do not change. Air gets trapped between the molecules in the cream. This makes the cream fluffy.
