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 Luke acquired this trait?

0. Luke's brother has scars on both of his knees.

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 John.

0. stayed the same
1. increased
2. decreased

[Assistant]
Think about how the distance between the water balloon and the center of Earth changed.
John was lower than the balcony. As the water balloon fell toward John, 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 John.
Therefore my final answer is: 2

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 rose plant's genotype for the flower color gene?

0. dark yellow flowers
1. ff

[Assistant]
An organism's genotype for a gene is its combination of alleles for that gene. The rose plant has two alleles for dark yellow flowers (f). So, the plant's genotype for the flower color gene is ff.

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 mile.
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 runners. Which runner was moving at a lower speed?

0. a runner who moved 35miles in 5hours
1. a runner who moved 25miles in 5hours

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...

Organisms that carry out photosynthesis are called photosynthetic organisms. During photosynthesis, these organisms use light energy to turn water and carbon dioxide into 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. Producers don't usually eat other organisms.
Their cells contain chloroplasts. Chloroplasts are cell parts where photosynthesis occurs.
Their chloroplasts often contain chlorophyll, which is green. Chlorophyll captures energy from sunlight to power photosynthesis.
They use the sugars they make during photosynthesis as food. This food provides the organisms with the energy they need to live.

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

0. Palm trees are commonly found on tropical beaches. Palm trees use carbon dioxide and water to make their food.

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 Scott acquired this trait?

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

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

0. a bag holding 6 pounds of food
1. a bag holding 3 pounds of food

[Assistant]
Look for the shopping bag that is heavier.
A shopping bag holding 6 pounds of food is heavier than a shopping bag holding 3 pounds of food. So, the bag holding 6 pounds needs a larger force to start moving upward at the same speed as the other bag.
Therefore my final answer is: 0


[User]
An object's velocity describes its speed and its direction.
An object has a constant velocity when neither its speed nor its direction is changing. So, an object has a constant velocity when the object is:
moving in a straight line at a constant speed, or
remaining motionless.
If an object does not have a constant velocity, the object is accelerating. An object is accelerating when either its speed or its direction is changing. So, an object is accelerating when the object is:
speeding up,
slowing down, or
changing direction.

Question:
Which statement describes the clown's motion?

[User]
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 Rollo's phenotype for the whisker type trait?

0. straight whiskers
1. curved whiskers

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

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. Peregrine falcons are the fastest animals in the world! They use their wings to fly quickly and hunt prey. Peregrine falcons also have a beak and feathers. They hatch from eggs with speckled or spotted shells.
1. Western gorillas have black, gray, or brown fur. Adult males are sometimes called silverbacks because they have often have gray fur on their backs. Female western gorillas feed their offspring milk.

[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 peregrine falcon has the following traits:
It has feathers.
It has wings.
It has a beak.
It makes eggs with shells.
A peregrine falcon does not have all of the traits of a mammal. A peregrine falcon is a bird.
A western gorilla has the following traits:
It feeds its offspring milk.
It has fur.
A western gorilla has the traits of a mammal. A western gorilla is a mammal.

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

0. brown eyes
1. red eyes

[Assistant]
The fruit fly's genotype for the eye color gene is ee. The fruit fly's genotype of ee has only e alleles. The e allele is for brown eyes. So, the fruit fly's phenotype for the eye color trait must be brown eyes.
To check this answer, consider whether the fruit fly's alleles are dominant or recessive. The allele for red eyes (E) is dominant over the allele for brown eyes (e). This means E is a dominant allele, and e is a recessive allele.
The fruit fly's genotype of ee has only recessive alleles. An organism with only recessive alleles for a gene will have the recessive allele's version of the trait. So, the fruit fly's phenotype for the eye color trait must be brown eyes.
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.
There are 60 minutes in 1 hour. So, 1 minute is much less than 1 hour.

Question:
How long does it take to wash your hands?

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.

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.

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

Gravitational potential energy is stored between any two objects. So, for every object on or near Earth, there is gravitational potential energy stored between the object and Earth.
The amount of gravitational potential energy stored between an object and Earth depends on the mass of the object. The amount of gravitational potential energy also depends on the distance between the object and the center of Earth. This distance increases when the object moves higher and decreases when the object moves lower.
If the distance between an object and the center of Earth changes, the gravitational potential energy stored between the object and Earth will change. The table below shows how this change can happen.
When an object's mass stays the same and its distance from the center of Earth... | Gravitational potential energy stored between the object and Earth...
increases | increases
decreases | decreases
stays the same | stays the same

Question:
Complete the statement. Assume that the motorcycle's mass did not change.
The gravitational potential energy stored between the motorcycle and Earth () as Lamar rode up the hill.

0. decreased
1. increased
2. stayed the same

[Assistant]
Think about how the distance between the motorcycle and the center of Earth changed.
The top of the hill is higher than the bottom of the hill. As Lamar rode toward the top of the hill, the distance between the motorcycle and the center of Earth increased. So, the gravitational potential energy stored between the motorcycle and Earth increased as Lamar rode up the hill.

All organisms have pieces of hereditary material called genes, which are passed from parents to offspring. Genes contain instructions for building the parts of an organism. An organism's genes affect its observable traits, including its appearance, its behavior, and which diseases it may have. Genes may have different alleles, or forms, that can cause different versions of a trait.
For example, flower color is a trait in pea plants. The gene for this trait has two possible alleles. Each allele is represented by an uppercase or lowercase letter. The allele F is for purple flowers, and the allele f is for white flowers. Each pea plant has two alleles for the flower color geneone allele inherited from each parent.
An organism's genotype for a gene is its combination of alleles for that gene. So, a pea plant may have a genotype of FF, Ff, or ff for the flower color gene.
An organism's phenotype for a trait is its observable version of that trait, which depends on the organism's combination of alleles. A pea plant may have a phenotype of purple flowers or white flowers for the flower color trait.

Question:
Based on this information, what is this pea plant's phenotype for the pea shape trait?

0. round peas
1. EE

[Assistant]
An organism's phenotype for a trait is its observable version of that trait. The pea plant's observable version of the pea shape trait is round peas. So, the plant's phenotype for the pea shape trait is round peas.

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:
Complete the statement.
Carbon dioxide is ().

0. a compound
1. an elementary substance

[Assistant]
You can tell whether carbon dioxide is an elementary substance or a compound by counting the number of symbols in its chemical formula. A symbol contains either one capital letter or a capital letter followed by one or two lowercase letters.
The chemical formula for carbon dioxide is CO2. This formula contains two symbols: C for carbon and O for oxygen. So, the formula tells you that carbon dioxide is made of two chemical elements bonded together.
Substances made of two or more chemical elements bonded together are compounds. So, carbon dioxide is a compound.

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

Question:
Which object has more thermal energy?

0. a 225-gram baked potato at a temperature of 100F
1. a 225-gram baked potato at a temperature of 115F

[Assistant]
The two baked potatoes have the same mass but different temperatures. Since the 115F potato is hotter than the 100F potato, it has more thermal energy.
Therefore my final answer is: 1

Poetry is a special kind of writing. It has many elements that make it different from ordinary writing. Knowing these elements can help you talk about poetry, understand it better, and enjoy it more.
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 has a regular rhythm, or a pattern of sound like a beat.

0. Within a green and shady bed
A modest violet grew;
Its stalk was bent, it hung its head,
As if to hide from view.
1. It was all so dull
Except a few gray legs under shiny black umbrellas
Running along the gray shiny sidewalks.

[Assistant]
This poem has a regular rhythm, or a pattern of sound like a beat. The parts in bold show the strong syllables. The pattern is a weak syllable followed by a strong syllable. It sounds like da-DUM da-DUM.

Informal writing is typically used in casual situations or when communicating with someone you know well. Informal language often expresses familiarity and tends to sound more like speech. It uses more conversational language, such as slang, idioms, abbreviations, imprecise language, and contractions.
Formal writing is typically used in academic and business writing or when writing directly to an authority figure. It tends to be more courteous and impersonal, avoiding overly familiar or conversational language.
Compare the following sentences.
Informal: Yeah, ostriches can't fly, but I think they're awesome.
More formal: Ostriches may be flightless, but they're remarkable runners.
Most formal: Though flightless, ostriches are remarkable runners.

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 sailboats. Which sailboat was moving at a lower speed?

0. a sailboat that moved 65kilometers in 5hours
1. a sailboat that moved 90kilometers in 5hours

[Assistant]
Look at the distance each sailboat moved and the time it took to move that distance.
One sailboat moved 65 kilometers in 5 hours.
The other sailboat moved 90 kilometers in 5 hours.
Notice that each sailboat spent the same amount of time moving. The sailboat that moved 65 kilometers moved a shorter distance in that time. So, that sailboat must have moved at a lower speed.

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.
