AP BIOLOGY EXAM ESSAY (FREE RESPONSE) QUESTIONS
General directions:
Answers must be in essay form. Labeled diagrams may be used to supplement discussion, but in no case will a diagram alone suffice. It is important that you read each question completely, and answer each section of the question. When giving examples, the first ones you give will be the ones graded. (if two examples are asked for, and you write about 4, make sure the first two are the best ones; they are the only ones counted!)
UNIT 1 BIOCHEMISTRY, WATER, ENZYMES
#1 (1996)
The unique properties of water make life possible on earth. Select three properties of water and
a. for each property, identify and define the property and explain it in terms of the physical/chemical …show more content…
Choose THREE of the following four types of cellular transport.
Osmosis
Active transport
Facilitated diffusion
Endocytosis/ Exocytosis
For each of the three types of transport you choose, a. describe the transport process and explain how the organization of cell membranes functions in the movement of specific molecules across membranes, and
b. explain the significance of each type of transport to a specific cell (you may use different cell types as examples)
#7 (2004)
Organisms differ from one another and yet share common characteristics. a. Select two kingdoms and briefly describe three characteristics used to distinguish between members of one kingdom and members of the other. b. Describe 3 characteristics (at least one cellular and one molecular) that members of these two kingdoms share. c. Propose an explanation for the existence of similarities and differences between the two kingdoms.
