2. QuestionMultiple choice

Why should a controlled experiment include repeated trials?

Please select an answer first.

Correct answer: B

The correct answer is Repeated trials improve reliability by showing whether a pattern is consistent..

  1. Identify the biology concept: Determine whether the question focuses on cells, heredity, evolution, ecology, or scientific modeling.
  2. Use evidence and vocabulary: Repeating trials helps identify random variation and increases confidence in a pattern.
  3. Check the conclusion: Confirm that the selected answer matches the biological relationship, process, or evidence described in the Georgia Milestones Biology EOC task.

Repeating trials helps identify random variation and increases confidence in a pattern.

3. QuestionMultiple choice

A graph shows enzyme activity increasing with temperature until 37 degrees Celsius, then rapidly decreasing. What is a reasonable explanation?

Please select an answer first.

Correct answer: C

The correct answer is The enzyme works best near an optimum and may lose shape at higher temperatures..

  1. Identify the biology concept: Determine whether the question focuses on cells, heredity, evolution, ecology, or scientific modeling.
  2. Use evidence and vocabulary: High temperatures can disrupt protein structure, while an intermediate temperature may support maximum activity.
  3. Check the conclusion: Confirm that the selected answer matches the biological relationship, process, or evidence described in the Georgia Milestones Biology EOC task.

High temperatures can disrupt protein structure, while an intermediate temperature may support maximum activity.

4. QuestionMultiple choice

A mutation changes a protein binding site and the protein no longer functions. What is the most direct cause?

Please select an answer first.

Correct answer: D

The correct answer is The amino acid sequence or folding of the protein was altered..

  1. Identify the biology concept: Determine whether the question focuses on cells, heredity, evolution, ecology, or scientific modeling.
  2. Use evidence and vocabulary: A DNA change can alter an amino acid sequence or protein shape and affect function.
  3. Check the conclusion: Confirm that the selected answer matches the biological relationship, process, or evidence described in the Georgia Milestones Biology EOC task.

A DNA change can alter an amino acid sequence or protein shape and affect function.

5. QuestionMultiple choice

A farmer grows the same crop repeatedly and adds nitrogen fertilizer. Which cycle is most directly involved?

Please select an answer first.

Correct answer: A

The correct answer is The nitrogen cycle.

  1. Identify the biology concept: Determine whether the question focuses on cells, heredity, evolution, ecology, or scientific modeling.
  2. Use evidence and vocabulary: Nitrogen fertilizer adds a nutrient used to build proteins and nucleic acids.
  3. Check the conclusion: Confirm that the selected answer matches the biological relationship, process, or evidence described in the Georgia Milestones Biology EOC task.

Nitrogen fertilizer adds a nutrient used to build proteins and nucleic acids.

6. QuestionMultiple choice

A population contains 80 organisms with a recessive phenotype controlled by a recessive allele. What additional information is needed before calculating allele frequency?

Please select an answer first.

Correct answer: B

The correct answer is The total population genotype or allele counts.

  1. Identify the biology concept: Determine whether the question focuses on cells, heredity, evolution, ecology, or scientific modeling.
  2. Use evidence and vocabulary: Phenotype counts alone may not identify all heterozygotes, so genotype or allele information is needed.
  3. Check the conclusion: Confirm that the selected answer matches the biological relationship, process, or evidence described in the Georgia Milestones Biology EOC task.

Phenotype counts alone may not identify all heterozygotes, so genotype or allele information is needed.

7. QuestionMultiple choice

A student claims that a larger animal must always have a higher metabolic rate than a smaller animal. Which evidence would best evaluate the claim?
