Biology: Advanced Topics Practice Tests

These Grade 11 Science practice tests examine cell biology, enzymes, cell division, molecular genetics, evolution, physiology, homeostasis, ecology, biodiversity, and experimental analysis.

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 homeostasis?

Please select an answer first.

Correct answer: A

The correct answer is Maintaining relatively stable internal conditions.

  1. Identify the biological system: Determine the cell process, inheritance pattern, physiological system, population, or ecosystem being described.
  2. Apply the biological principle: Homeostasis uses feedback and regulation to keep variables within suitable ranges despite external changes.
  3. Check evidence and scale: The correct answer is Maintaining relatively stable internal conditions.

Homeostasis uses feedback and regulation to keep variables within suitable ranges despite external changes.

2. QuestionMultiple choice

What is negative feedback?

Please select an answer first.

Correct answer: B

The correct answer is A response that counteracts a change and returns a variable toward a set range.

  1. Identify the biological system: Determine the cell process, inheritance pattern, physiological system, population, or ecosystem being described.
  2. Apply the biological principle: Negative feedback reduces deviation from a target or range and stabilizes physiological conditions.
  3. Check evidence and scale: The correct answer is A response that counteracts a change and returns a variable toward a set range.

Negative feedback reduces deviation from a target or range and stabilizes physiological conditions.

3. QuestionMultiple choice

What is the role of insulin in blood-glucose regulation?

Please select an answer first.

Correct answer: C

The correct answer is It promotes uptake and storage of glucose when blood glucose is high.

  1. Identify the biological system: Determine the cell process, inheritance pattern, physiological system, population, or ecosystem being described.
  2. Apply the biological principle: Insulin lowers blood glucose by promoting cellular uptake and storage, including glycogen formation.
  3. Check evidence and scale: The correct answer is It promotes uptake and storage of glucose when blood glucose is high.

Insulin lowers blood glucose by promoting cellular uptake and storage, including glycogen formation.

4. QuestionMultiple choice

What is the main function of hemoglobin?

Please select an answer first.

Correct answer: D

The correct answer is Transporting oxygen in red blood cells.

  1. Identify the biological system: Determine the cell process, inheritance pattern, physiological system, population, or ecosystem being described.
  2. Apply the biological principle: Hemoglobin binds oxygen reversibly, allowing red blood cells to transport it from lungs to tissues.
  3. Check evidence and scale: The correct answer is Transporting oxygen in red blood cells.

Hemoglobin binds oxygen reversibly, allowing red blood cells to transport it from lungs to tissues.

5. QuestionMultiple choice

What is the role of alveoli in the lungs?

Please select an answer first.

Correct answer: A

The correct answer is Providing a large surface for gas exchange by diffusion.

  1. Identify the biological system: Determine the cell process, inheritance pattern, physiological system, population, or ecosystem being described.
  2. Apply the biological principle: Thin, moist alveolar surfaces and dense capillary networks support diffusion of oxygen and carbon dioxide.
  3. Check evidence and scale: The correct answer is Providing a large surface for gas exchange by diffusion.

Thin, moist alveolar surfaces and dense capillary networks support diffusion of oxygen and carbon dioxide.

6. QuestionMultiple choice

What is an antibody?

Please select an answer first.

Correct answer: B

The correct answer is A protein made by B cells that binds a specific antigen.

  1. Identify the biological system: Determine the cell process, inheritance pattern, physiological system, population, or ecosystem being described.
  2. Apply the biological principle: Antibodies recognize molecular features on antigens and can help neutralize or mark pathogens.
  3. Check evidence and scale: The correct answer is A protein made by B cells that binds a specific antigen.

Antibodies recognize molecular features on antigens and can help neutralize or mark pathogens.

7. QuestionMultiple choice

What is the role of a neuron's axon?

Please select an answer first.

Correct answer: C

The correct answer is Conducting electrical signals away from the cell body.

  1. Identify the biological system: Determine the cell process, inheritance pattern, physiological system, population, or ecosystem being described.
  2. Apply the biological principle: An axon carries action potentials from the cell body toward axon terminals and target cells.
  3. Check evidence and scale: The correct answer is Conducting electrical signals away from the cell body.

An axon carries action potentials from the cell body toward axon terminals and target cells.

8. QuestionMultiple choice

What is a synapse?

Please select an answer first.

Correct answer: D

The correct answer is A junction where a neuron communicates with another cell.

  1. Identify the biological system: Determine the cell process, inheritance pattern, physiological system, population, or ecosystem being described.
  2. Apply the biological principle: At a synapse, electrical or chemical signals cross a junction to influence a postsynaptic cell.
  3. Check evidence and scale: The correct answer is A junction where a neuron communicates with another cell.

At a synapse, electrical or chemical signals cross a junction to influence a postsynaptic cell.

9. QuestionMultiple choice

What is the function of thyroid hormone in general metabolism?

Please select an answer first.
