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 Austen inherited this trait?

0. Austen's mother has blue eyes. She passed this trait down to Austen.
1. Austen likes to wear a blue sweater to match his blue eyes.

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 Abigail's genotype for the albinism gene?

0. Aa
1. not having albinism

[Assistant]
An organism's genotype for a gene is its combination of alleles for that gene. Abigail has one allele for not having albinism (A) and one allele for having albinism (a). So, Abigail's genotype for the albinism gene is Aa.

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 mole's mass did not change.
The gravitational potential energy stored between the mole and Earth () as the mole dug toward the surface.

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:

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.
Crushing a mineral into powder is a ().

Authors use different text structures to organize their ideas in writing. Learning to identify these structures will help you to understand the relationships between ideas in informational texts. You can also use these structures to organize your own writing.
A cause-effect structure presents the causes and the effects of a particular event, trend, or situation. This structure often uses words and phrases such as because, since, as a result, due to, or consequently.
A compare-contrast structure presents similarities (comparisons) and differences (contrasts) between two or more things. This structure often uses words and phrases such as like, similarly, or in the same way (for comparing) or on the other hand, in contrast, or unlike (for contrasting).
A problem-solution structure presents a problem and suggests one or more possible solutions. This structure often uses words such as issue, question, puzzle, propose, and answer.
A sequential structure describes a series of events that happens in a certain order. This structure often uses specific dates and times or words such as first, next, during, finally, and while.

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 8 long. You might be thinking, 8 what? Is the pencil 8 inches long? 8 feet? 8 miles?
The number 8 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 inches. So, the length of the pencil is 8 inches.
There are 12 inches in 1 foot. So, 1 inch is much shorter than 1 foot.
There are 3 feet in 1 yard. So, 1 foot is shorter than 1 yard.

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.

A poem rhymes when it has a pattern of words that end in the same sound.
End rhyme is when the rhymes appear at the end of a poem's lines.
Little Betty Blue,
Lost her holiday shoe.
From Mother Goose
Internal rhyme is when at least one of the rhyming words appears inside the poem's lines.
Sweet dreams of pleasant streams.
From William Blake, "A Cradle Song"
Rhythm is the pattern of strong and weak syllables, or stress, in a poem. You can recognize rhythm in a poem by listening to how it sounds. Poems with regular rhythm have a beat, like in music.
He watches from his mountain walls,
And like a thunderbolt he falls.
From Alfred, Lord Tennyson, "The Eagle"
The syllables in bold are strong. We say them with more force than the other syllables. In this poem, every weak syllable is followed by a strong syllable. Each line sounds like da-DUM da-DUM da-DUM da-DUM. To better hear the rhythm, try reading it aloud while clapping on each strong syllable.
Free verse is when a poem has neither a regular rhythm nor a rhyme pattern.
The old bridge has a wrinkled face.
He bends his back
For us to go over.
From Hilda Conkling, "The Old Bridge"
The syllables in bold are strong. You can see this poem does not have a regular rhythm. It also doesn't have a rhyme pattern.
Repetition is when words, phrases, or whole lines are repeated.
The dainty flying squirrel
In vest of shining white,
In coat of silver gray,
And vest of shining white.
Adapted from Mary E. Burt, "The Flying Squirrel"
Alliteration is when beginning consonant sounds are repeated in words that are close together.
Where the wild men watched and waited
Wolves in the forest, and bears in the bush.
From Bayard Taylor, "A Night with a Wolf"
Onomatopoeia is when language sounds like what it talks about.
Sometimes the onomatopoeia uses made-up words:
Tlot-tlot! tlot-tlot! Had they heard it? The horse hoofs ringing clear.
From Alfred Noyes, "The Highwayman"
Sometimes the onomatopoeia uses real words:
Hark! the honey bee is humming.
From Mary Howitt, "The Voice of Spring"

Question:
Choose the poem that uses repetition.

0. The lonely bridge cuts dark across the marsh
Whose long pools glow with the light
Of a flaming summer sunset.

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.
The advertisements say that this nail polish dries in less than five minutes.

A force is a push or a pull that acts on an object. Every force has a direction and a magnitude, or strength. If two forces act on an object in opposite directions, the forces are called opposing forces.
When opposing forces have the same magnitude, they are balanced. If all the forces on an object are balanced, there is no net force on the object.
When opposing forces have different magnitudes, the forces are unbalanced. If any forces on an object are unbalanced, there is a net force on the object.

Question:
Assume all other forces on Mackenzie are balanced. Which statement describes the forces on Mackenzie?

0. The forces are unbalanced, so there is a net force on Mackenzie.
1. The forces are balanced, so there is no net force on Mackenzie.

[Assistant]
To determine if there is a net force on Mackenzie, look at the forces:
Earth's gravity is pulling Mackenzie down with a force of 600 N.
The seat of the cart is pushing Mackenzie up with a force of 1,200 N.
The forces are in opposite directions, and the forces have different magnitudes: 600 N and 1,200 N. This means that the forces are unbalanced, so there is a net force on Mackenzie.
Therefore my final answer is: 0

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.
Deep-frying chicken is a ().

0. chemical change

Measurements are written with both a number and a unit. The unit comes after the number. The unit shows what the number means.
When you are using metric units, length can be written with units of millimeters, centimeters, meters, or kilometers. One meter contains 100 centimeters or 1,000 millimeters. So, 1 meter is larger than 1 centimeter, and 1 centimeter is larger than 1 millimeter.
The tip of the pencil shown here is only 1 millimeter wide, but the pencil is about 16 centimeters long.
A red fox is about 1 meter long. The Sydney Harbour Bridge in Australia is about 1,000 meters, or 1 kilometer, in length.

Question:
How long is a paper clip?

0. 27 kilometers
1. 27 meters

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.
Sodium hydroxide is ().

0. an elementary substance
1. a compound

[Assistant]
You can tell whether sodium hydroxide 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 sodium hydroxide, NaOH, contains three atomic symbols: Na for sodium, O for oxygen, and H for hydrogen. So, the formula tells you that sodium hydroxide is composed of three chemical elements bonded together.
Since sodium hydroxide is composed of multiple chemical elements bonded together, sodium hydroxide is a compound.
Therefore my final answer is: 1


[User]
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.

Question:
How long is a long-distance running race?

0. 28 kilometers
1. 28 centimeters

[Assistant]
The better estimate for the length of a long-distance running race is 28 kilometers.
28 centimeters is too short.
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 this tomato plant's genotype for the fruit texture gene?

0. fuzzy fruit

A vertebrate has a backbone. The backbone is made of many bones in an animal's back. A vertebrate's backbone helps connect the different parts of its body. In the drawings below, each vertebrate's backbone is colored orange.
An invertebrate does not have a backbone. In fact, invertebrates do not have any bones! Some invertebrates have an outer cover on their body called an exoskeleton. Other invertebrates have a soft body.

Question:
Select the vertebrate.

0. hissing cockroach
1. mosquito
2. forest scorpion
3. cardinalfish

[Assistant]
A mosquito is an insect. Like other insects, a mosquito is an invertebrate. It does not have a backbone. It has an exoskeleton.
Like other scorpions, a forest scorpion is an invertebrate. It does not have a backbone. It has an exoskeleton.
A cardinalfish is a fish. Like other fish, a cardinalfish is a vertebrate. It has a backbone.
A hissing cockroach is an insect. Like other insects, a hissing cockroach is an invertebrate. It does not have a backbone. It has an exoskeleton.

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.
Dichloromethane is ().

0. an elementary substance
1. a compound

[Assistant]
You can tell whether dichloromethane 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 dichloromethane, CH2 Cl2, contains three atomic symbols: C for carbon, H for hydrogen, and Cl for chlorine. So, the formula tells you that dichloromethane is composed of three chemical elements bonded together.
Since dichloromethane is composed of multiple chemical elements bonded together, dichloromethane is a compound.
Therefore my final answer is: 1

Similes and metaphors are figures of speech that compare two things that are not actually alike.
A simile compares two things by saying that one is like the other. Similes often use the words like and as.
My sister runs like a cheetah.
The sister's running and a cheetah's running are compared using the word like.
A cheetah is known for running fast, so the simile means that the sister also runs fast.
The cat's fur was as dark as the night.
The cat's fur and the night are compared using the word as.
The night is dark, so the simile means that the cat's fur is also dark.
A metaphor compares two things by saying that one of them is the other. Unlike similes, metaphors don't use the word like or as.
The snow formed a blanket over the town.
The snow and a blanket are compared without the word like or as.
A blanket is a large piece of cloth that completely covers a bed. The metaphor makes the reader imagine that the snow becomes a blanket, covering the town completely.
Using similes and metaphors in your writing can help you create an interesting picture for the reader.

Question:
Does the sentence use a simile or a metaphor?
Mrs. Hutchinson is an owl, working at night and sleeping during the day.

0. metaphor
1. simile

[Assistant]
Mrs. Hutchinson is an owl, working at night and sleeping during the day.
The words Mrs. Hutchinson and owl are compared without the word like or as. So, the sentence uses a metaphor.

Measurements are written with both a number and a unit. The unit comes after the number. The unit shows what the number means.
Mass is a measurement of how much matter something contains.
There are many different units of mass. When you are using customary units, mass may be written with units of ounces, pounds, or tons.
There are 16 ounces in 1 pound and 2,000 pounds in 1 ton.
So, 1 ounce is less than 1 pound and much less than 1 ton.
A slice of bread has a mass of about 1 ounce, while a can of beans has a mass of about 1 pound. A small car has a mass of about 1 ton.

Question:
What is the mass of a skateboard?

0. 5 pounds
1. 5 tons

[Assistant]
The best estimate for the mass of a skateboard is 5 pounds.
5 ounces is too light and 5 tons is too heavy.
Therefore my final answer is: 0


[User]
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.
Ice crystals forming on a window is a ().

0. chemical change
1. physical change

[Assistant]
Ice crystals forming on a window is a change of state. So, it is a physical change. Water vapor in the air can change directly into ice when it touches a very cold window! A change of state from a gas to a solid is called depositing.
Therefore my final answer is: 1

A force is a push or a pull that acts on an object. Every force has a direction and a magnitude, or strength. If two forces act on an object in opposite directions, the forces are called opposing forces.
When opposing forces have the same magnitude, they are balanced. If all the forces on an object are balanced, there is no net force on the object.
When opposing forces have different magnitudes, the forces are unbalanced. If any forces on an object are unbalanced, there is a net force on the object.

Question:
Assume all other forces on Reba are balanced. Which statement describes the forces on Reba?

0. The forces are unbalanced, so there is a net force on Reba.
1. The forces are balanced, so there is no net force on Reba.

[Assistant]
To determine if there is a net force on Reba, look at the forces:
Earth's gravity is pulling Reba down with a force of 600 N.
The seat of the cart is pushing Reba up with a force of 1,200 N.
The forces are in opposite directions, and the forces have different magnitudes: 600 N and 1,200 N. This means that the forces are unbalanced, so there is a net force on Reba.
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 blue jays. Which blue jay was moving at the lowest speed?

0. a blue jay that moved 400kilometers west in 10hours
1. a blue jay that moved 405kilometers south in 10hours
2. a blue jay that moved 335kilometers east in 10hours

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 Dusty's phenotype for the body hair trait?

0. a hairless body
1. a hairy body

[Assistant]
Dusty's genotype for the body hair gene is bb. Dusty's genotype of bb has only b alleles. The b allele is for a hairless body. So, Dusty's phenotype for the body hair trait must be a hairless body.
To check this answer, consider whether Dusty's alleles are dominant or recessive. The allele for a hairless body (b) is recessive to the allele for a hairy body (B). This means B is a dominant allele, and b is a recessive allele.
Dusty's genotype of bb has only recessive alleles. An organism with only recessive alleles for a gene will have the recessive allele's version of the trait. So, Dusty's phenotype for the body hair trait must be a hairless body.
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 the bus leaves in 7. You might be thinking, 7 what? Does the bus leave in 7 minutes? 7 seconds?
The number 7 on its own does not give you much information about when the bus is leaving. That is because the units are missing.
Time is usually measured in units of seconds, minutes, or hours. It takes about 1 second to sneeze and 1 minute to get dressed in the morning. It takes about 1 hour to bake a pie in the oven.
There are 60 seconds in 1 minute. So, 1 second is much less than 1 minute.
