What are some examples of FRQ (free response questions) on the AP biology exam?

The Advanced Placement Biology Exam free-response sections include questions relating to describing the process of embryological development in vertebrates, identifying the developmental origins of tissue in vertebrates and explaining properties of embryonic cells. The questions may require essay response with labeling of related diagrams as needed.

Examples of free response questions for the AP Biology Exam are released each year from the previous year's test by College Board. These samples give test-takers a good sense of how questions may be worded and areas that may be covered on the test. However, exact content and wording of the exam questions changes each year.
