1. QuestionMultiple choice

Where is genetic information stored in a cell?

Please select an answer first.

Correct answer: A

The correct answer is DNA.

  1. Identify the science idea: Decide whether the question is about ecosystems, matter, energy, Earth systems, forces, heredity, or scientific evidence.
  2. Use the evidence: DNA stores instructions that influence traits and cell functions.
  3. Check the claim: Make sure the answer matches the model, observation, data, or system described.

DNA stores instructions that influence traits and cell functions.

2. QuestionMultiple choice

What is a gene?

Please select an answer first.

Correct answer: B

The correct answer is A section of DNA that contains instructions for a trait or function.

  1. Identify the science idea: Decide whether the question is about ecosystems, matter, energy, Earth systems, forces, heredity, or scientific evidence.
  2. Use the evidence: Genes are segments of DNA that provide instructions for proteins or functional products.
  3. Check the claim: Make sure the answer matches the model, observation, data, or system described.

Genes are segments of DNA that provide instructions for proteins or functional products.

3. QuestionMultiple choice

If two parents each pass one allele for a trait to their child, what does the child receive?

Please select an answer first.

Correct answer: C

The correct answer is One allele from each parent.

  1. Identify the science idea: Decide whether the question is about ecosystems, matter, energy, Earth systems, forces, heredity, or scientific evidence.
  2. Use the evidence: Offspring inherit genetic information from both biological parents.
  3. Check the claim: Make sure the answer matches the model, observation, data, or system described.

Offspring inherit genetic information from both biological parents.

4. QuestionMultiple choice

Which trait is most clearly inherited rather than learned?

Please select an answer first.

Correct answer: D

The correct answer is Natural eye color.

  1. Identify the science idea: Decide whether the question is about ecosystems, matter, energy, Earth systems, forces, heredity, or scientific evidence.
  2. Use the evidence: Natural eye color is strongly influenced by inherited genetic information.
  3. Check the claim: Make sure the answer matches the model, observation, data, or system described.

Natural eye color is strongly influenced by inherited genetic information.

5. QuestionMultiple choice

Why can siblings have different combinations of traits?

Please select an answer first.

Correct answer: A

The correct answer is They may inherit different combinations of alleles from the same parents.

  1. Identify the science idea: Decide whether the question is about ecosystems, matter, energy, Earth systems, forces, heredity, or scientific evidence.
  2. Use the evidence: Different allele combinations can produce differences among siblings.
  3. Check the claim: Make sure the answer matches the model, observation, data, or system described.

Different allele combinations can produce differences among siblings.

6. QuestionMultiple choice

What is an adaptation?

Please select an answer first.

Correct answer: B

The correct answer is An inherited characteristic that helps an organism survive and reproduce.

  1. Identify the science idea: Decide whether the question is about ecosystems, matter, energy, Earth systems, forces, heredity, or scientific evidence.
  2. Use the evidence: Adaptations are inherited traits that can improve an organism’s success in its environment.
  3. Check the claim: Make sure the answer matches the model, observation, data, or system described.

Adaptations are inherited traits that can improve an organism’s success in its environment.

7. QuestionMultiple choice

A population of insects includes some individuals resistant to a pesticide. After repeated spraying, resistant insects become more common. What best explains this pattern?

Please select an answer first.

Correct answer: C

The correct answer is Natural selection favored the inherited resistance.

  1. Identify the science idea: Decide whether the question is about ecosystems, matter, energy, Earth systems, forces, heredity, or scientific evidence.
  2. Use the evidence: Resistant individuals were more likely to survive and reproduce, increasing the frequency of resistance.
  3. Check the claim: Make sure the answer matches the model, observation, data, or system described.

Resistant individuals were more likely to survive and reproduce, increasing the frequency of resistance.

8. QuestionMultiple choice

Which evidence most strongly supports that two species share a common ancestor?

Please select an answer first.

Correct answer: D

The correct answer is Similar underlying structures with different functions.

  1. Identify the science idea: Decide whether the question is about ecosystems, matter, energy, Earth systems, forces, heredity, or scientific evidence.
  2. Use the evidence: Homologous structures can reveal inherited similarities from a common ancestor.
  3. Check the claim: Make sure the answer matches the model, observation, data, or system described.

Homologous structures can reveal inherited similarities from a common ancestor.

9. QuestionMultiple choice

What does a fossil record provide evidence about?

Please select an answer first.

Correct answer: A

The correct answer is How organisms and environments have changed over time.

  1. Identify the science idea: Decide whether the question is about ecosystems, matter, energy, Earth systems, forces, heredity, or scientific evidence.
  2. Use the evidence: Fossils provide evidence of past organisms, traits, and environmental conditions.
  3. Check the claim: Make sure the answer matches the model, observation, data, or system described.

Fossils provide evidence of past organisms, traits, and environmental conditions.

10. QuestionMultiple choice

Why is variation important to a population facing a new environmental change?

Please select an answer first.

Correct answer: B

The correct answer is Some inherited traits may help individuals survive and reproduce.

  1. Identify the science idea: Decide whether the question is about ecosystems, matter, energy, Earth systems, forces, heredity, or scientific evidence.
  2. Use the evidence: Variation gives natural selection differences on which it can act.
  3. Check the claim: Make sure the answer matches the model, observation, data, or system described.

Variation gives natural selection differences on which it can act.
