1. QuestionMultiple choice

Which process helps an organism maintain a stable internal condition?

Please select an answer first.

Correct answer: A

The correct answer is Homeostasis.

  1. Identify the evidence: Read the model, data, or scenario and identify the scientific quantities and relationships provided.
  2. Apply the science idea: Homeostasis uses feedback and regulation to keep internal conditions within a suitable range.
  3. Check the result: Make sure the conclusion or calculation is consistent with the evidence and units.

Homeostasis uses feedback and regulation to keep internal conditions within a suitable range.

2. QuestionMultiple choice

Why can an enzyme speed up a biochemical reaction?

Please select an answer first.

Correct answer: B

The correct answer is It lowers the activation energy required.

  1. Identify the evidence: Read the model, data, or scenario and identify the scientific quantities and relationships provided.
  2. Apply the science idea: Enzymes provide a pathway with lower activation energy and are not consumed by the reaction.
  3. Check the result: Make sure the conclusion or calculation is consistent with the evidence and units.

Enzymes provide a pathway with lower activation energy and are not consumed by the reaction.

3. QuestionMultiple choice

What is the main purpose of DNA replication before cell division?

Please select an answer first.

Correct answer: C

The correct answer is To provide each new cell with a copy of genetic information.

  1. Identify the evidence: Read the model, data, or scenario and identify the scientific quantities and relationships provided.
  2. Apply the science idea: Replication copies DNA so daughter cells can receive genetic instructions.
  3. Check the result: Make sure the conclusion or calculation is consistent with the evidence and units.

Replication copies DNA so daughter cells can receive genetic instructions.

4. QuestionMultiple choice

Which molecule carries instructions from DNA to a ribosome during protein synthesis?

Please select an answer first.

Correct answer: D

The correct answer is Messenger RNA.

  1. Identify the evidence: Read the model, data, or scenario and identify the scientific quantities and relationships provided.
  2. Apply the science idea: Messenger RNA carries a copied sequence from DNA to the ribosome.
  3. Check the result: Make sure the conclusion or calculation is consistent with the evidence and units.

Messenger RNA carries a copied sequence from DNA to the ribosome.

5. QuestionMultiple choice

What is the main product of cellular respiration that cells use for immediate work?

Please select an answer first.

Correct answer: A

The correct answer is ATP.

  1. Identify the evidence: Read the model, data, or scenario and identify the scientific quantities and relationships provided.
  2. Apply the science idea: Cellular respiration transfers energy from food into ATP, which powers cellular work.
  3. Check the result: Make sure the conclusion or calculation is consistent with the evidence and units.

Cellular respiration transfers energy from food into ATP, which powers cellular work.

6. QuestionMultiple choice

A population has very little genetic variation. Which risk increases?

Please select an answer first.

Correct answer: B

The correct answer is A single disease or environmental change may affect many individuals.

  1. Identify the evidence: Read the model, data, or scenario and identify the scientific quantities and relationships provided.
  2. Apply the science idea: Low variation can reduce the number of traits available to help a population respond.
  3. Check the result: Make sure the conclusion or calculation is consistent with the evidence and units.

Low variation can reduce the number of traits available to help a population respond.

7. QuestionMultiple choice

Which evidence most directly supports the idea that two species share a common ancestor?

Please select an answer first.

Correct answer: C

The correct answer is Similar DNA sequences and homologous structures.

  1. Identify the evidence: Read the model, data, or scenario and identify the scientific quantities and relationships provided.
  2. Apply the science idea: Shared genetic sequences and structural patterns can reflect inherited ancestry.
  3. Check the result: Make sure the conclusion or calculation is consistent with the evidence and units.

Shared genetic sequences and structural patterns can reflect inherited ancestry.

8. QuestionMultiple choice

In an energy pyramid, why is less energy available at higher trophic levels?

Please select an answer first.

Correct answer: D

The correct answer is Much energy is used for life processes and released as heat at each level.

  1. Identify the evidence: Read the model, data, or scenario and identify the scientific quantities and relationships provided.
  2. Apply the science idea: Energy transfer between trophic levels is inefficient because organisms use energy for metabolism.
  3. Check the result: Make sure the conclusion or calculation is consistent with the evidence and units.

Energy transfer between trophic levels is inefficient because organisms use energy for metabolism.

9. QuestionMultiple choice

What happens when a population exceeds the carrying capacity of its environment?

Please select an answer first.

Correct answer: A

The correct answer is Limited resources can cause population size to decline.

  1. Identify the evidence: Read the model, data, or scenario and identify the scientific quantities and relationships provided.
  2. Apply the science idea: Food, water, space, or other limits can increase competition and reduce population size.
  3. Check the result: Make sure the conclusion or calculation is consistent with the evidence and units.

Food, water, space, or other limits can increase competition and reduce population size.

10. QuestionMultiple choice

Why can a diverse ecosystem be more resilient after a disturbance?

Please select an answer first.

Correct answer: B

The correct answer is Multiple species and interactions can support continued ecosystem functions.

  1. Identify the evidence: Read the model, data, or scenario and identify the scientific quantities and relationships provided.
  2. Apply the science idea: Biodiversity provides different roles and responses that can help an ecosystem recover.
  3. Check the result: Make sure the conclusion or calculation is consistent with the evidence and units.
