1. QuestionMultiple choice

How are photosynthesis and cellular respiration related?

Please select an answer first.

Correct answer: A

The correct answer is The products of one process can serve as reactants for the other.

  1. Identify the evidence: Read the observation, model, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: Photosynthesis stores energy in glucose and produces oxygen; respiration uses glucose and oxygen to release energy.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

Photosynthesis stores energy in glucose and produces oxygen; respiration uses glucose and oxygen to release energy.

2. QuestionMultiple choice

What is one possible effect of a mutation in DNA?

Please select an answer first.

Correct answer: B

The correct answer is It may change a protein or have no noticeable effect.

  1. Identify the evidence: Read the observation, model, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: A mutation can alter genetic instructions, but its effect depends on where it occurs.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

A mutation can alter genetic instructions, but its effect depends on where it occurs.

3. QuestionMultiple choice

Which statement illustrates Newton's third law?

Please select an answer first.

Correct answer: C

The correct answer is A swimmer pushes water backward and the water pushes the swimmer forward.

  1. Identify the evidence: Read the observation, model, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: The swimmer and water exert equal and opposite forces on each other.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

The swimmer and water exert equal and opposite forces on each other.

4. QuestionMultiple choice

Which energy transformation occurs in a flashlight?

Please select an answer first.

Correct answer: D

The correct answer is Chemical energy becomes electrical energy and then light energy.

  1. Identify the evidence: Read the observation, model, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: The battery stores chemical energy that the circuit converts into light and some heat.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

The battery stores chemical energy that the circuit converts into light and some heat.

5. QuestionMultiple choice

A substance with a pH of 3 is best described as what?

Please select an answer first.

Correct answer: A

The correct answer is Acidic.

  1. Identify the evidence: Read the observation, model, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: Values below 7 on the pH scale are acidic.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

Values below 7 on the pH scale are acidic.

6. QuestionMultiple choice

How does burning fossil fuel affect the carbon cycle?

Please select an answer first.

Correct answer: B

The correct answer is It moves stored carbon into the atmosphere as carbon dioxide.

  1. Identify the evidence: Read the observation, model, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: Combustion releases carbon that was stored in fossil fuels into the atmosphere.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

Combustion releases carbon that was stored in fossil fuels into the atmosphere.

7. QuestionMultiple choice

Why can increased greenhouse gases warm Earth's atmosphere?

Please select an answer first.

Correct answer: C

The correct answer is They absorb and re-emit some outgoing infrared energy.

  1. Identify the evidence: Read the observation, model, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: Greenhouse gases interact with outgoing infrared radiation and can increase heat retained in the atmosphere.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

Greenhouse gases interact with outgoing infrared radiation and can increase heat retained in the atmosphere.

8. QuestionMultiple choice

What happens when a population reaches its carrying capacity?

Please select an answer first.

Correct answer: D

The correct answer is Resources limit further long-term population growth.

  1. Identify the evidence: Read the observation, model, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: Carrying capacity is the largest population an environment can support over time.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

Carrying capacity is the largest population an environment can support over time.

9. QuestionMultiple choice

Why can biodiversity help an ecosystem recover from disturbance?

Please select an answer first.

Correct answer: A

The correct answer is Different species may perform overlapping roles and respond differently.

  1. Identify the evidence: Read the observation, model, or scenario and identify the scientific evidence provided.
  2. Apply the science idea: A diverse ecosystem may have more pathways and species able to continue functioning after change.
  3. Check the conclusion: Make sure the conclusion is supported by the evidence and matches the question.

A diverse ecosystem may have more pathways and species able to continue functioning after change.

10. QuestionMultiple choice

What makes a scientific explanation strong?

Please select an answer first.

Correct answer: B

The correct answer is It connects a claim to relevant evidence and scientific reasoning.

  1. Identify the evidence: Read the observation, model, or scenario and identify the scientific evidence provided.
