Every substance around you is made of one or more chemical elements, or types of atoms. Substances that are made of only one chemical element are elementary substances. Substances that are made of two or more chemical elements bonded together are compounds.
Every chemical element is represented by its own symbol. For some elements, the symbol is one capital letter. For other elements, the symbol is one capital letter and one lowercase letter. For example, the symbol for the element fluorine is F, and the symbol for the element beryllium is Be.
The symbol for each element in a substance is shown in the substance's chemical formula.
An elementary substance is represented by a chemical formula that contains only one symbol.
The symbol may be followed by a subscript. A subscript is text that is smaller and placed lower than the normal line of text. A subscript is included when the atoms in the elementary substance are bonded to form molecules. The subscript tells you the number of atoms in each molecule.
For example, the chemical formula for the elementary substance oxygen is O2. The formula has a subscript of 2. This subscript tells you that there are two atoms in the molecule represented by this chemical formula.
The chemical element represented by the symbol O is also called oxygen. So, the formula O2 tells you that each molecule of O2 contains two oxygen atoms.
A compound is represented by a chemical formula that contains multiple symbols.
For example, in the compound beryllium fluoride, there is one beryllium atom for every two fluorine atoms. This combination is shown in the compound's chemical formula, BeF2. In the formula, the symbol Be represents one beryllium atom. The symbol F followed by the subscript 2 represents two fluorine atoms.

Question:
Select the elementary substance.

0. hydrogen peroxide (H2O2)
1. beryllium (Be)
2. fluoromethane (CH3F)

[Assistant]
Look at the chemical formula for each substance, and count the number of symbols in the formula. Then, decide if the substance is an elementary substance. The chemical formula for beryllium contains one symbol: Be. So, beryllium is made of one chemical element. Substances that are made of one chemical element are elementary substances. So, beryllium is an elementary substance. The chemical formula for hydrogen peroxide contains two symbols: H for hydrogen and O for oxygen. So, hydrogen peroxide is made of two chemical elements bonded together. Substances that are made of two or more chemical elements bonded together are compounds. So, hydrogen peroxide is a compound, not an elementary substance. The chemical formula for fluoromethane contains three symbols: C for carbon, H for hydrogen, and F for fluorine. So, fluoromethane is made of three chemical elements bonded together. Substances that are made of two or more chemical elements bonded together are compounds. So, fluoromethane is a compound, not an elementary substance.
Therefore my final answer is: 1

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 sailboats. Which sailboat was moving at the lowest speed?

0. a sailboat that moved 50kilometers north in 5hours
1. a sailboat that moved 70kilometers west in 5hours
2. a sailboat that moved 25kilometers east in 5hours

[Assistant]
Look at the distance each sailboat moved and the time it took to move that distance. The direction each sailboat moved does not affect its speed.
Notice that each sailboat moved for 5 hours. The sailboat that moved 25 kilometers moved the shortest distance in that time. So, that sailboat must have moved at the lowest speed.
Therefore my final answer is: 2


[User]
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 Jennifer are balanced. Which statement describes the forces on Jennifer?

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

[Assistant]
To determine if there is a net force on Jennifer, look at the forces:
Earth's gravity is pulling Jennifer down with a force of 600 N.
The seat of the cart is pushing Jennifer 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 Jennifer.
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 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:

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. Ff

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:

All three fish tanks have the same mass but different temperatures. Since the 17C fish tank is the coldest, it has the least thermal energy.
Therefore my final answer is: 0


[User]
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 bucket of water has a higher temperature?

0. the bucket of water with less thermal energy
1. the bucket of water with more thermal energy

[Assistant]
The two buckets of water are made of the same material and have the same mass. So, the bucket of water with more thermal energy has a higher temperature.

Solid, liquid, and gas are states of matter. Matter is anything that takes up space. Matter can come in different states, or forms.
When matter is a solid, it has a definite volume and a definite shape. So, a solid has a size and shape of its own.
Some solids can be easily folded, bent, or broken. A piece of paper is a solid. Also, some solids are very small. A grain of sand is a solid.
When matter is a liquid, it has a definite volume but not a definite shape. So, a liquid has a size of its own, but it does not have a shape of its own. Think about pouring juice from a bottle into a cup. The juice still takes up the same amount of space, but it takes the shape of the bottle.
Some liquids do not pour as easily as others. Honey and milk are both liquids. But pouring honey takes more time than pouring milk.
When matter is a gas, it does not have a definite volume or a definite shape. A gas expands, or gets bigger, until it completely fills a space. A gas can also get smaller if it is squeezed into a smaller space.
Many gases are invisible. Air is a gas.

Question:
Select the solid.

0. pencil
1. rain puddle
2. helium
3. wet paint

[Assistant]
Helium is a gas. A gas expands to fill a space. Helium is lighter than air. So, if you fill a balloon with helium, the balloon will rise. If helium leaks out of the balloon, the helium will expand into the space around the balloon.
A pencil is a solid. You can break a pencil into pieces. But each piece will still have a size and shape of its own.
Wet paint is a liquid. A liquid takes the shape of any container it is in. If you pour wet paint out of a can, the paint will change shape. But the wet paint will still take up the same amount of space.
A rain puddle is a liquid. A liquid takes the shape of any container it is in. If you collect rainwater in a bucket, the rainwater will take the shape of the bucket. But the rainwater will still take up the same amount of space.
Therefore my final answer is: 0

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 Jordan acquired this trait?

0. Jordan's neighbor taught him how to repair a kite.
1. Jordan likes to fly a kite with his younger brother.
2. Jordan's friend taught him how to fly a kite.

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

Question:
Which object has less thermal energy?

0. an 800-gram rock at a temperature of 270F
1. an 800-gram rock at a temperature of 250F

Words change in meaning when speakers begin using them in new ways. For example, the word peruse once only meant to examine in detail, but it's now also commonly used to mean to look through in a casual manner.
When a word changes in meaning, its correct usage is often debated. Although a newer sense of the word may be more commonly used, many people consider a word's traditional definition to be the correct usage. Being able to distinguish the different uses of a word can help you use it appropriately for different audiences.

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

0. green body feathers
1. blue body feathers

[Assistant]
Babel's genotype for the body feather color gene is BB. Babel's genotype of BB has only B allelles. The B allele is for green body feathers. So, Babel's phenotype for the body feather color trait must be green body feathers.
To check this answer, consider whether Babel's alleles are dominant or recessive. The allele for green body feathers (B) is dominant over the allele for blue body feathers (b). This means B is a dominant allele, and b is a recessive allele.
Babel's genotype of BB has two dominant alleles. An organism with at least one dominant allele for a gene will have the dominant allele's version of the trait. So, Babel's phenotype for the body feather color trait must be green body feathers.
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.

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 Greg inherited this trait?

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

There are four kinds of sentences.
A declarative sentence is a statement, and it always ends with a period.
The nurse told Mr. Abrams to roll up his sleeve so that she could check his blood pressure.
An interrogative sentence is a question, and it always ends with a question mark.
Do you have any plans for the upcoming weekend?
An imperative sentence is a command. It makes a request or tells someone to do something, and it usually ends with a period. If the command shows strong feeling, it ends with an exclamation point.
For this assignment, use references to support your claims.
Don't drive so quickly in the construction zone!
An exclamatory sentence is like a statement, but it shows surprise or strong feeling. An exclamatory sentence always ends with an exclamation point.
I can't wait to travel through Europe this summer!

Question:
What kind of sentence is this?
Call a plumber as soon as you can and explain that the pipes are clogged.

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 kitchen table?

0. 9 inches

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.

Poets often use the sounds of words to create interesting effects and to express moods and emotions. Understanding these elements of poetry can help you better interpret and appreciate poetic forms.
Anaphora is the repetition of words or sequences of words at the beginning of multiple phrases, sentences, or lines.
Out of the cradle endlessly rocking,
Out of the mocking-bird's throat, the musical shuttle,
Out of the Ninth-month midnight

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.

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"
Assonance is the repetition of vowel sounds. Often, assonance can create rhymes or near-rhymes within lines.
I wandered lonely as a Cloud
That floats on high o'er Vales and Hills,
When all at once I saw a crowd,
A host of golden Daffodils.
From William Wordsworth, "I Wandered Lonely as a Cloud"
Meter is a poem's rhythm, or the pattern of strong and weak syllables. Strong syllables are stressed, while weak syllables are unstressed.
A poem has an iambic meter when the beat sounds like da-DUM. A weak syllable is followed by a strong syllable. Occasionally, a line may begin with a strong syllable.
He watches from his mountain walls,
And like a thunderbolt he falls.
From Alfred, Lord Tennyson, "The Eagle"
A poem has a trochaic meter when the beat sounds like DUM-da. A strong syllable is followed by a weak syllable. Occasionally, a line may end in a strong syllable.
Back into the chamber turning, all my soul within me burning,
Soon again I heard a tapping somewhat louder than before.
From Edgar Allen Poe, "The Raven"
Free verse is when a poem has neither a regular rhythm nor a rhyme pattern.

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 pod color trait?

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.

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:
Which text uses the word unique in its traditional sense?

0. Alan custom ordered his unique coffee table from a master craftsman in Allenville.
1. Alan bought his unique coffee table from a factory outlet store in Allenville.

[Assistant]
The first text uses unique in its traditional sense: being the only one of its kind.

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 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 ships. Which ship was moving at the lowest speed?

0. a ship that moved 310miles east in 10hours
1. a ship that moved 265miles east in 10hours
2. a ship that moved 145miles north in 10hours

[Assistant]
Look at the distance each ship moved and the time it took to move that distance. The direction each ship moved does not affect its speed.
Notice that each ship moved for 10 hours. The ship that moved 145 miles moved the shortest distance in that time. So, that ship must have moved at the lowest speed.

All organisms need food. Food gives organisms the energy they need to survive.
Animals get their food by eating other organisms. An animal's digestive system breaks down food into small particles of fat, protein, sugar, and other nutrients. The blood carries these small particles to cells throughout the animal's body.
Inside cells, nutrient particles can be broken down to release energy. Cells need energy to do their jobs. A cell's job might include sending signals to other cells, rearranging chemicals to make new substances, or moving substances from place to place.
Cells also use nutrient particles as building materials. Cells use building materials to help the animal grow and to replace worn-out parts.

Question:
Which job does the digestive system do?

0. helps cells get energy from food
1. helps make food

[Assistant]
The digestive system breaks down food into small particles of nutrients. Cells can get energy and building materials from these small particles.
