The circulatory system moves oxygen, nutrients, and wastes between body systems.

3. QuestionMultiple choice

A population of rabbits has more brown fur than white fur after many generations in a forest. Which explanation is best?

Please select an answer first.

Correct answer: C

The correct answer is Brown fur can help rabbits blend into the forest..

  1. Read the ILEARN science task: Identify the system, evidence, variables, model, or phenomenon described in the question.
  2. Use the evidence: If brown fur improves camouflage, those rabbits may survive and reproduce more often.
  3. Check the claim: Confirm that the answer is supported by the information in the question and matches the scientific concept.

If brown fur improves camouflage, those rabbits may survive and reproduce more often.

4. QuestionMultiple choice

Which process produces two genetically identical body cells?

Please select an answer first.

Correct answer: D

The correct answer is Mitosis.

  1. Read the ILEARN science task: Identify the system, evidence, variables, model, or phenomenon described in the question.
  2. Use the evidence: Mitosis makes two cells with the same genetic information as the original cell.
  3. Check the claim: Confirm that the answer is supported by the information in the question and matches the scientific concept.

Mitosis makes two cells with the same genetic information as the original cell.

5. QuestionMultiple choice

Why are decomposers important in an ecosystem?

Please select an answer first.

Correct answer: A

The correct answer is They return matter to the environment..

  1. Read the ILEARN science task: Identify the system, evidence, variables, model, or phenomenon described in the question.
  2. Use the evidence: Decomposers break down dead matter and return nutrients to soil and water.
  3. Check the claim: Confirm that the answer is supported by the information in the question and matches the scientific concept.

Decomposers break down dead matter and return nutrients to soil and water.

6. QuestionMultiple choice

A student observes that a bean plant grows taller when it receives more light. Which variable is being changed?

Please select an answer first.

Correct answer: B

The correct answer is Amount of light.

  1. Read the ILEARN science task: Identify the system, evidence, variables, model, or phenomenon described in the question.
  2. Use the evidence: The amount of light is the independent variable because the student changes it.
  3. Check the claim: Confirm that the answer is supported by the information in the question and matches the scientific concept.

The amount of light is the independent variable because the student changes it.

7. QuestionMultiple choice

Which statement describes a food web?

Please select an answer first.

Correct answer: C

The correct answer is It shows connected feeding relationships in an ecosystem..

  1. Read the ILEARN science task: Identify the system, evidence, variables, model, or phenomenon described in the question.
  2. Use the evidence: A food web combines several food chains and shows how organisms are connected.
  3. Check the claim: Confirm that the answer is supported by the information in the question and matches the scientific concept.

A food web combines several food chains and shows how organisms are connected.

8. QuestionMultiple choice

What is one likely result if a disease greatly reduces the number of insects in a meadow?

Please select an answer first.

Correct answer: D

The correct answer is Some insect-eating birds may have less food..

  1. Read the ILEARN science task: Identify the system, evidence, variables, model, or phenomenon described in the question.
  2. Use the evidence: Birds and other insect eaters may have less available energy when insect numbers fall.
  3. Check the claim: Confirm that the answer is supported by the information in the question and matches the scientific concept.
