  • Photosynthesis, cellular respiration, food webs, trophic levels, energy transfer, decomposers, and nutrient cycling
  • DNA, RNA, protein synthesis, heredity, Punnett squares, mutations, meiosis, natural selection, and common ancestry
  • Population growth, carrying capacity, symbiosis, habitat fragmentation, carbon cycling, biodiversity, and conservation
  • Integrated biology reasoning with experimental variables, ecosystem services, evidence, models, and claim-evidence-reasoning explanations

How to use this page

Complete one 10-question set at a time. Use the model, data, or biological process in each question as evidence. Review the explanation after each response and note whether the missed skill involves structure, energy, inheritance, ecology, or investigation.

This is supplemental State Test Practice, State Assessment Practice, and Standardized Test Practice for Florida Biology 1 EOC preparation. It does not replace current Florida Department of Education guidance, official assessment materials, accommodations, or testing policies.

1. QuestionMultiple choice

A student places identical plant cuttings in different light conditions and measures oxygen bubbles. Which result would best support the claim that light affects photosynthesis?

Please select an answer first.

Correct answer: A

The correct answer is Cuttings in brighter light produce more oxygen bubbles when other conditions are controlled..

  1. Identify the biology concept: Read the process, model, data, or organism interaction carefully and identify the biological relationship being tested.
  2. Choose the best answer: More oxygen in brighter light supports a relationship between light and photosynthesis.
  3. Check the evidence: Make sure the answer matches the structure, process, energy flow, inheritance pattern, or evidence described in the question.

More oxygen in brighter light supports a relationship between light and photosynthesis.

2. QuestionMultiple choice

A mutation changes a protein that controls cell division. Which outcome is most concerning?

Please select an answer first.

Correct answer: B

The correct answer is Uncontrolled cell division.

  1. Identify the biology concept: Read the process, model, data, or organism interaction carefully and identify the biological relationship being tested.
  2. Choose the best answer: A damaged cell-division control protein can contribute to uncontrolled growth.
  3. Check the evidence: Make sure the answer matches the structure, process, energy flow, inheritance pattern, or evidence described in the question.

A damaged cell-division control protein can contribute to uncontrolled growth.

3. QuestionMultiple choice

A pesticide kills many insects, but a few resistant insects survive and reproduce. What is the likely long-term result?

Please select an answer first.

Correct answer: C

The correct answer is Resistance becomes more common in the insect population..

  1. Identify the biology concept: Read the process, model, data, or organism interaction carefully and identify the biological relationship being tested.
  2. Choose the best answer: Surviving resistant insects pass the trait to offspring, increasing its frequency.
  3. Check the evidence: Make sure the answer matches the structure, process, energy flow, inheritance pattern, or evidence described in the question.

Surviving resistant insects pass the trait to offspring, increasing its frequency.

4. QuestionMultiple choice

A food web includes grass, rabbits, snakes, and hawks. If grass decreases greatly, which immediate effect is most likely?

Please select an answer first.

Correct answer: D

The correct answer is Rabbit numbers may decrease because less food is available..

  1. Identify the biology concept: Read the process, model, data, or organism interaction carefully and identify the biological relationship being tested.
  2. Choose the best answer: Rabbits depend directly on grass, so a decrease in grass can reduce rabbit numbers.
  3. Check the evidence: Make sure the answer matches the structure, process, energy flow, inheritance pattern, or evidence described in the question.

Rabbits depend directly on grass, so a decrease in grass can reduce rabbit numbers.

5. QuestionMultiple choice

A cell is placed in a solution and gains water until it swells. What can be inferred about the solution?

Please select an answer first.

Correct answer: A

The correct answer is The solution has a lower solute concentration than the cell..

  1. Identify the biology concept: Read the process, model, data, or organism interaction carefully and identify the biological relationship being tested.
  2. Choose the best answer: Water enters a cell when the surrounding solution has lower solute concentration.
  3. Check the evidence: Make sure the answer matches the structure, process, energy flow, inheritance pattern, or evidence described in the question.

Water enters a cell when the surrounding solution has lower solute concentration.

6. QuestionMultiple choice

A researcher compares the growth of bacteria at four temperatures and repeats each temperature five times. Why are repeated trials useful?

Please select an answer first.

Correct answer: B

The correct answer is They improve reliability by showing whether the pattern is consistent..

  1. Identify the biology concept: Read the process, model, data, or organism interaction carefully and identify the biological relationship being tested.
  2. Choose the best answer: Repeated trials help determine whether results are consistent rather than due to chance.
  3. Check the evidence: Make sure the answer matches the structure, process, energy flow, inheritance pattern, or evidence described in the question.

Repeated trials help determine whether results are consistent rather than due to chance.

7. QuestionMultiple choice

A diagram shows a gene being copied into mRNA and mRNA being used at a ribosome. Which sequence is represented?

Please select an answer first.

Correct answer: C

The correct answer is Transcription followed by translation.

  1. Identify the biology concept: Read the process, model, data, or organism interaction carefully and identify the biological relationship being tested.

DNA information is transcribed into mRNA, which is translated into a protein at a ribosome.

8. QuestionMultiple choice

A wetland is drained for construction. Which combined effect is most likely?

Please select an answer first.

Correct answer: D

The correct answer is Loss of habitat and reduced water filtration..

  1. Identify the biology concept: Read the process, model, data, or organism interaction carefully and identify the biological relationship being tested.
  2. Choose the best answer: Wetlands provide habitat and filter water, so drainage can reduce both services.
  3. Check the evidence: Make sure the answer matches the structure, process, energy flow, inheritance pattern, or evidence described in the question.

Wetlands provide habitat and filter water, so drainage can reduce both services.

9. QuestionMultiple choice

A student compares the DNA sequences of two species and finds many similar sections. What conclusion is most supported?
