Skills covered

  • Connecting cell structures, membranes, enzymes, osmosis, mitosis, and cell-cycle regulation to function
  • Explaining DNA replication, transcription, translation, mutations, gene regulation, and inheritance evidence
  • Applying natural selection, genetic drift, gene flow, Hardy-Weinberg ideas, speciation, and phylogenetic reasoning
  • Analyzing homeostasis, feedback, immunity, circulation, respiration, nervous systems, and endocrine regulation
  • Interpreting energy flow, population limits, biodiversity, biomagnification, controls, uncertainty, and biological data

How to use these practice tests

Identify the biological scale first, from molecule and cell to organism, population, or ecosystem. Then connect the evidence to the relevant mechanism and distinguish correlation from a supported causal explanation.

1. QuestionMultiple choice

What is the main function of the cell membrane?

Please select an answer first.

Correct answer: A

The correct answer is Regulating movement of substances into and out of the cell.

  1. Identify the biological system: Determine the cell process, inheritance pattern, physiological system, population, or ecosystem being described.
  2. Apply the biological principle: The selectively permeable membrane controls exchange with the environment and helps maintain internal conditions.
  3. Check evidence and scale: The correct answer is Regulating movement of substances into and out of the cell.

The selectively permeable membrane controls exchange with the environment and helps maintain internal conditions.

2. QuestionMultiple choice

What is the role of mitochondria in eukaryotic cells?

Please select an answer first.

Correct answer: B

The correct answer is Producing much of the cell's ATP through cellular respiration.

  1. Identify the biological system: Determine the cell process, inheritance pattern, physiological system, population, or ecosystem being described.
  2. Apply the biological principle: Mitochondria use energy-rich molecules and oxygen in aerobic respiration to produce ATP for cellular work.
  3. Check evidence and scale: The correct answer is Producing much of the cell's ATP through cellular respiration.

Mitochondria use energy-rich molecules and oxygen in aerobic respiration to produce ATP for cellular work.

3. QuestionMultiple choice

What is the function of ribosomes?

Please select an answer first.

Correct answer: C

The correct answer is Synthesizing proteins from messenger RNA information.

  1. Identify the biological system: Determine the cell process, inheritance pattern, physiological system, population, or ecosystem being described.
  2. Apply the biological principle: Ribosomes translate mRNA codons and join amino acids into a polypeptide.
  3. Check evidence and scale: The correct answer is Synthesizing proteins from messenger RNA information.

Ribosomes translate mRNA codons and join amino acids into a polypeptide.

4. QuestionMultiple choice

What is the endoplasmic reticulum with ribosomes attached called?

Please select an answer first.

Correct answer: D

The correct answer is Rough endoplasmic reticulum.

  1. Identify the biological system: Determine the cell process, inheritance pattern, physiological system, population, or ecosystem being described.
  2. Apply the biological principle: Ribosomes give the rough ER its appearance and allow synthesis and initial processing of many secreted or membrane proteins.
  3. Check evidence and scale: The correct answer is Rough endoplasmic reticulum.

Ribosomes give the rough ER its appearance and allow synthesis and initial processing of many secreted or membrane proteins.

5. QuestionMultiple choice

What is osmosis?

Please select an answer first.

Correct answer: A

The correct answer is The net movement of water across a selectively permeable membrane.

  1. Identify the biological system: Determine the cell process, inheritance pattern, physiological system, population, or ecosystem being described.
  2. Apply the biological principle: Osmosis is passive water movement driven by differences in water potential or solute concentration.
  3. Check evidence and scale: The correct answer is The net movement of water across a selectively permeable membrane.

Osmosis is passive water movement driven by differences in water potential or solute concentration.

6. QuestionMultiple choice

What happens to an animal cell in a strongly hypertonic solution?

Please select an answer first.

Correct answer: B

The correct answer is It loses water and shrinks.

  1. Identify the biological system: Determine the cell process, inheritance pattern, physiological system, population, or ecosystem being described.
  2. Apply the biological principle: A hypertonic external solution has lower water availability, so water leaves the cell by osmosis.
  3. Check evidence and scale: The correct answer is It loses water and shrinks.

A hypertonic external solution has lower water availability, so water leaves the cell by osmosis.

7. QuestionMultiple choice

What do enzymes do in biochemical reactions?

Please select an answer first.

Correct answer: C

The correct answer is They lower activation energy without being consumed.

  1. Identify the biological system: Determine the cell process, inheritance pattern, physiological system, population, or ecosystem being described.
  2. Apply the biological principle: Enzymes are biological catalysts that provide a lower-energy pathway and remain available after the reaction.
  3. Check evidence and scale: The correct answer is They lower activation energy without being consumed.

Enzymes are biological catalysts that provide a lower-energy pathway and remain available after the reaction.

8. QuestionMultiple choice

What happens when an enzyme is denatured?

Please select an answer first.

Correct answer: D

The correct answer is Its three-dimensional shape changes and its function can be reduced.

  1. Identify the biological system: Determine the cell process, inheritance pattern, physiological system, population, or ecosystem being described.
  2. Apply the biological principle: Changes in temperature, pH, or chemicals can disrupt bonds that maintain an enzyme's active shape.
  3. Check evidence and scale: The correct answer is Its three-dimensional shape changes and its function can be reduced.

Changes in temperature, pH, or chemicals can disrupt bonds that maintain an enzyme's active shape.

9. QuestionMultiple choice
