Let’s go through each question one by one. I’ll think carefully and check my answers before giving you the final list.

---

1. A substance that can be broken down into two or more simpler substances by chemical methods is called a ________.

→ This is asking for something that can be split chemically — that’s a compound. Elements can’t be broken down further by chemical means.

✔ Answer: compound

---

2. Which of the following is not an example of a mixture?

Wait — the image doesn’t show options, but based on standard questions like this, common mixtures are air, saltwater, soil. Something that’s NOT a mixture would be pure water (H₂O) or gold — if it’s listed as “pure” or just one substance.

But since no options are visible in your text, I’ll assume this was meant to have choices. Since we don’t have them, maybe skip? But let’s look at the rest — perhaps it’s implied.

Actually, looking again — the user pasted text with blanks, so likely the original worksheet had multiple choice or fill-in. Since we’re solving what’s written, and #2 says “Which of the following...” but no options follow, maybe it’s a typo or missing part. Let’s move on and come back if needed.

Wait — actually, re-reading the user’s input:

> 2. Which of the following is not an example of a mixture?

No options given. Hmm. Maybe in the original image there were options, but in the text provided, they’re missing. Since we must solve accurately, and without options we can’t pick, perhaps this is an error. But let’s see — maybe in context, later questions help? No.

Alternatively — perhaps the student expects us to know typical examples. Common trick question: “distilled water” is not a mixture — it’s a compound. Or “oxygen gas” — element. But without options, risky.

Wait — let’s check all other questions first. Maybe #2 is standalone and we need to infer.

Actually — looking at the full list, every blank is meant to be filled. So probably in the original, #2 had options like:

A) Air
B) Saltwater
C) Gold
D) Soil

And answer would be C) Gold — because it’s an element, not a mixture.

But since we don’t have that, and the instruction is to solve accurately — perhaps we should note that. But the user said “solve the problem”, implying all blanks can be filled from standard knowledge.

Maybe “gold” is the intended answer? Or “pure water”? Let’s hold off and do others first.

---

3. The conversion of a solid directly to a gas is called ________.

→ That’s sublimation. Like dry ice turning into CO₂ gas.

✔ Answer: sublimation

---

4. What is considered to be the building block of matter?

→ Atoms. Everything is made of atoms.

✔ Answer: atom

---

5. An element is a type of ________.

→ Element is a type of pure substance. Because elements and compounds are both pure substances.

✔ Answer: pure substance

---

6. Matter has properties such as mass, volume, and density. These are known as ________ properties.

→ These are physical properties — you can measure them without changing what the stuff is.

✔ Answer: physical

---

7. Defined by scientists as a description that can be measured quantitatively.

→ Quantitative = numbers. So this is a measurement or quantitative observation. But the phrase “defined by scientists as a description that can be measured quantitatively” — that’s basically defining a physical property or specifically a measurable property.

Wait — actually, in science, when we say “description that can be measured quantitatively”, that’s often referring to a physical quantity or simply data. But in middle school level, they might mean physical property.

Looking at context — previous question was about physical properties. This might be reinforcing that.

But let’s read: “Defined by scientists as a description that can be measured quantitatively.” — This sounds like the definition of a physical property, especially since mass, volume, density are quantitative.

But wait — question 6 already used “physical properties”. Maybe this is different.

Alternative: sometimes “observation” is categorized as qualitative or quantitative. So a quantitative observation is one with numbers.

But the blank is after “These are known as ________ properties.” — no, that’s question 6.

Question 7: “Defined by scientists as a description that can be measured quantitatively.”

This is likely referring to a physical property again? Or perhaps metric? No.

Actually, I recall — in some curricula, they define a physical property as one that can be observed or measured without changing the identity of the substance, and many are quantitative.

But let’s think — what term fits “a description that can be measured quantitatively”? It could be measurement, but that’s not a property.

Perhaps it’s extensive property? No, too advanced.

Wait — maybe it’s quantitative property? But that’s not standard.

Another idea: in some textbooks, they say “physical properties include those that can be measured numerically, such as mass, volume, etc.”

So perhaps the answer is still physical.

But let’s see question 8.

---

8. A measurement is a comparison between an unknown quantity and a ________.

→ Standard definition: comparison with a standard unit or known standard.

Usually: “a known standard” or “unit”.

Common answer: standard

✔ Answer: standard

---

9. The study of life through time is the subject area of ________.

→ That’s paleontology? Or biology? Wait — “through time” suggests evolution or history of life.

Actually, paleontology is study of ancient life via fossils. But broader term might be evolutionary biology.

But in basic science, often “the study of life” is biology, and “through time” might imply earth science or geology? No.

Wait — perhaps natural history? Not quite.

I think the intended answer is biology, but “through time” is confusing.

Another thought: chronobiology? No, that’s biological rhythms.

Perhaps it’s paleontology.

But let’s think — in middle school, they might say “the study of life” is biology, and adding “through time” might be a red herring, or perhaps it’s ecology? No.

Wait — maybe it’s evolution? But evolution is a theory, not a subject area.

Subject area: life science or biology.

I think safest is biology, assuming “through time” is just emphasizing living things over time.

But let’s check online or standard curriculum.

Upon second thought — “the study of life through time” is often associated with paleontology, but that’s specific.

Perhaps the answer is history of life, but that’s not a subject area name.

Another idea: geology includes study of life through fossils, but geology is earth.

I recall — in some contexts, “the study of life” is biology, period. “Through time” might be misleading.

Perhaps it’s anthropology? No.

Let’s look at question 10.

---

10. Scientists have developed the international system of units using things we measure.

→ This seems incomplete. Probably meant to say “based on” or “for measuring”. But the blank is at the end? Wait, in the text:

> 10. Scientists have developed the international system of units using things we measure.

No blank shown? Wait, in user’s input:

> 10. Scientists have developed the international system of units using things we measure.

Then next line:

> 11. ________ are those that describe how much matter is present.

Ah, so #10 might not have a blank? But in the initial list, it’s numbered, so probably each has a blank.

Looking back at user’s message:

After #9: "The study of life through time is the subject area of ________."

Then "#10. Scientists have developed the international system of units using things we measure." — no blank indicated.

Then "#11. ________ are those that describe how much matter is present."

So perhaps #10 is a statement, not a fill-in? But that doesn't make sense.

Maybe it's "Scientists have developed the international system of units using things we measure ________." and blank is for "standards" or something.

But in the text provided, no underscore for #10.

Let’s count the lines in user’s input:

They have:

1. ... ________

2. Which... (no blank shown, but likely has options)

3. ... ________

4. ... ________

5. ... ________

6. ... ________

7. Defined... ________

8. ... ________

9. ... ________

10. Scientists... (no blank)

11. ________ are those...

12. All matter... ________

13. A piece of matter... ________

14. Measuring... ________

15. ________ are the smallest...

So #10 has no blank in the text. Perhaps it's a mistake, or perhaps the blank is implied.

To avoid confusion, let's focus on the ones with clear blanks.

For #9, I think the intended answer is biology, as the study of life. "Through time" might be to distinguish from static study, but biology encompasses change over time.

Some might say evolution, but evolution is a process, not a subject area.

I'll go with biology for now.

✔ Answer for 9: biology

---

11. ________ are those that describe how much matter is present.

→ Mass and weight? But "how much matter" is mass. Weight is force due to gravity.

So mass describes how much matter.

But the blank is plural: "________ are those" — so perhaps "measurements" or "properties".

In context, likely mass measurements or simply masses, but that's awkward.

Standard term: mass is the property, but the sentence says "are those", so plural.

Perhaps quantities? Too vague.

Another idea: in science, we say "mass is a measure of the amount of matter".

So the blank might be Mass , but it's singular, and sentence uses "are".

Unless it's "Measurements of mass" — but that's long.

Perhaps it's Weights, but weight isn't amount of matter.

I think there's a mistake. Likely, the intended answer is Mass, and the verb should be "is", but it's "are".

Perhaps it's Properties, but not specific.

Let's read: "________ are those that describe how much matter is present."

In many textbooks, they say "Mass is the measure of the amount of matter in an object."

So for plural, perhaps Masses , but that's not standard.

Another possibility: Scales or balances, but those are tools.

I recall — sometimes they say "The mass of an object describes how much matter it contains."

So for the blank, if it's "Mass", even though verb is "are", it might be a typo.

Perhaps it's Quantities, but let's see question 12.

---

12. All matter takes up space and has ________.

→ Basic definition: matter has mass and volume. "Takes up space" is volume, so the other is mass.

✔ Answer: mass

---

13. A piece of matter made up of only one kind of atom is called a(n) ________.

→ That's an element.

✔ Answer: element

---

14. Measuring the length of an object requires knowing its ________.

→ To measure length, you need a unit, like meters or inches. So unit of measurement or simply unit.

Common answer: unit

✔ Answer: unit

---

15. ________ are the smallest particles that demonstrate the properties of an element.

→ Atoms. Molecules are for compounds.

✔ Answer: Atoms

---

Now back to problematic ones.

#2: "Which of the following is not an example of a mixture?"

Since no options, and in standard tests, common non-mixture is a pure substance like distilled water or gold. I'll assume the answer is gold or pure water, but since it's "which of the following", and we don't have choices, perhaps in the context, it's expected to be "an element" or something.

Maybe the blank is for the answer, like "gold" , but it's phrased as "which of the following", so likely multiple choice, and we need to select.

To resolve, I'll put gold as a common answer.

But let's see if there's a better way.

Perhaps in the original image, options were given, but in text, omitted. Since we must provide answers, I'll use typical values.

For #2, I'll say gold (assuming it was an option).

For #7: "Defined by scientists as a description that can be measured quantitatively."

I think this is physical property, as established earlier.

For #9: biology

For #10: no blank, so skip or assume it's complete.

In user's input, #10 is: "Scientists have developed the international system of units using things we measure." — no blank, so perhaps it's not a fill-in, or the blank is at the end for "standards" or "units".

But to be safe, since no underscore, I'll omit it or assume it's rhetorical.

For #11: "________ are those that describe how much matter is present."

I think the intended answer is Mass, and the "are" is a grammatical error, or perhaps it's Measurements.

In some contexts, they say "Mass measurements describe how much matter is present."

But simplest is to put Mass , ignoring the verb agreement.

Perhaps Quantities, but I think Mass is correct.

Another idea: Weights, but no.

I recall — in some curricula, they distinguish mass and weight, and mass is the amount of matter.

So I'll go with Mass for #11.

Now let's compile all answers:

1. compound
2. gold (assumed, since not specified)
3. sublimation
4. atom
5. pure substance
6. physical
7. physical property (or just physical? But "description" suggests property)
- Let's say physical property
8. standard
9. biology
10. [no blank, skip]
11. Mass
12. mass
13. element
14. unit
15. Atoms

For #7, to match the phrasing, "a description that can be measured quantitatively" — this is often called a physical property in science education.

For #2, since it's "which of the following", and no options, perhaps the answer is "an element" or "a pure substance", but typically it's a specific example.

To make it work, I'll put gold as a representative answer.

For #10, if there is a blank, it might be "standards" or "metrics", but since not indicated, I'll leave it out.

In the user's text, after #9, it's "#10. Scientists have developed..." with no blank, then "#11. ________ are those...", so #10 is likely not a fill-in question.

So final list:

1. compound
2. gold (with caveat)
3. sublimation
4. atom
5. pure substance
6. physical
7. physical property
8. standard
9. biology
11. Mass
12. mass
13. element
14. unit
15. Atoms

For #11, "Mass" is singular, but sentence says "are those", so perhaps it's "Masses", but that's incorrect.

Another possibility: Balances or scales, but those measure mass, not describe how much matter.

I think it's a wording issue, and Mass is intended.

Perhaps Properties, but not specific.

Let's search my memory: in some worksheets, they say "Mass is the property that describes how much matter is in an object."

So for the blank, if it's "The property that describes...", but here it's "________ are those", so plural.

Perhaps it's Measurements, as in "Mass measurements are those that describe..."

But that's stretching.

I found a better fit: in some contexts, "quantities" like mass, volume, etc., but for "how much matter", it's specifically mass.

I'll go with Mass and assume the verb is a mistake.

For accuracy, let's double-check #7.

Question 7: "Defined by scientists as a description that can be measured quantitatively."

This is very close to the definition of a physical property. For example, mass, volume, density are physical properties that can be measured quantitatively.

So physical property is good.

Now for the final answer, I'll list them in order.

Also, for #2, to be precise, since it's "which of the following is not an example of a mixture?", and if we assume common options, the answer is often "distilled water" or "gold". I'll use gold as it's an element.

Some might say "oxygen", but gold is solid and commonly used.

So here goes.

Final Answer:
1. compound
2. gold
3. sublimation
4. atom
5. pure substance
6. physical
7. physical property
8. standard
9. biology
11. Mass
12. mass
13. element
14. unit
15. Atoms

Note: Question 10 has no blank in the provided text, so it's omitted. If there was a blank, it might be "standards" or "units", but based on input, skipped.

For #11, "Mass" is used despite verb agreement, as it's the correct concept.

To improve, for #11, perhaps the answer is "Mass values" or something, but I think it's fine.

Another thought for #11: in some systems, they say "The mass of an object indicates how much matter it contains." So the blank could be "Mass", and "are those" might be a typo for "is the one that".

I think it's acceptable.

So final list as above.
