1. QuestionMultiple choice

Which cell structure captures light energy for photosynthesis in a plant cell?

Please select an answer first.

Correct answer: A

The correct answer is Chloroplast.

  1. Identify the evidence: Read the observation, model, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: Chloroplasts contain pigments that capture light energy used in photosynthesis.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

Chloroplasts contain pigments that capture light energy used in photosynthesis.

2. QuestionMultiple choice

In the food chain grass → rabbit → hawk, which organism gets energy directly from the grass?

Please select an answer first.

Correct answer: B

The correct answer is Rabbit.

  1. Identify the evidence: Read the observation, model, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: The rabbit is the consumer that eats the grass directly.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

The rabbit is the consumer that eats the grass directly.

3. QuestionMultiple choice

Which example is an inherited trait?

Please select an answer first.

Correct answer: C

The correct answer is A child having a gene-linked blood type.

  1. Identify the evidence: Read the observation, model, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: Inherited traits are passed through genetic information from parents.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

Inherited traits are passed through genetic information from parents.

4. QuestionMultiple choice

What is the most likely result if a predator is removed from an ecosystem?

Please select an answer first.

Correct answer: D

The correct answer is The prey population may increase.

  1. Identify the evidence: Read the observation, model, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: With fewer predators, prey may survive and reproduce in greater numbers.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

With fewer predators, prey may survive and reproduce in greater numbers.

5. QuestionMultiple choice

Why do scientists use microscopes to study many cells?

Please select an answer first.

Correct answer: A

The correct answer is Cells are often too small to see clearly without magnification.

  1. Identify the evidence: Read the observation, model, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: Magnification reveals structures that are too small for the unaided eye.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

Magnification reveals structures that are too small for the unaided eye.

6. QuestionMultiple choice

Which body system exchanges oxygen and carbon dioxide with the environment?

Please select an answer first.

Correct answer: B

The correct answer is Respiratory system.

  1. Identify the evidence: Read the observation, model, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: The respiratory system brings oxygen into the body and removes carbon dioxide.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

The respiratory system brings oxygen into the body and removes carbon dioxide.

7. QuestionMultiple choice

How do cactus spines help a cactus survive in a dry environment?

Please select an answer first.

Correct answer: C

The correct answer is They reduce water loss and discourage herbivores.

  1. Identify the evidence: Read the observation, model, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: Spines are modified leaves that reduce exposed surface area and can protect the plant.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

Spines are modified leaves that reduce exposed surface area and can protect the plant.

8. QuestionMultiple choice

What is the role of decomposers in an ecosystem?

Please select an answer first.

Correct answer: D

The correct answer is They return nutrients to the environment by breaking down dead matter.

  1. Identify the evidence: Read the observation, model, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: Decomposers break down dead material and recycle nutrients.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

Decomposers break down dead material and recycle nutrients.

9. QuestionMultiple choice

How does natural selection change a population over many generations?

Please select an answer first.

Correct answer: A

The correct answer is Traits that improve survival and reproduction become more common.

  1. Identify the evidence: Read the observation, model, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: Individuals with advantageous inherited traits are more likely to pass those traits on.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

Individuals with advantageous inherited traits are more likely to pass those traits on.

10. QuestionMultiple choice
