AP BIOLOGY FINAL EXAM QUESTIONS AND CORRECT
ANSWERS
Question 1
Humans produce sweat as a cooling mechanism
to maintain a stable internal temperature. Which
of the following best explains how the properties
of water contribute to this physiological process?
Correct Answer
The high heat of vaporization of water
allows the body to remove excess heat
through a phase change of water from
liquid to gas

,Question 2
A student placed a semipermeable membrane
inside a U-shaped channel with two chambers,
as shown. The membrane permits the movement
of water but not salt. The student wants to vary
the rate of osmosis that occurs across the
membrane. Which of the following
experimental designs will result in the fastest net
rate of water movement into chamber A?
Correct Answer
Placing salt water in chamber A and
distilled water in chamber B

,Question 3
Which of the following best describes the role of
water in photosynthesis?
Correct Answer
Water molecules donate electrons to the
electron transport chain
Question 4
What evolutionary advantage does
compartmentalization of core metabolic
processes offer eukaryotes?
Correct Answer
Evolution of a nucleus in eukaryotes
separates the processes of transcription
and translation and they can be regulated
separately

, Question 5
Which of the following best describes the
cellular location where pyruvate dehydrogenase
is most likely active?
Correct Answer
The mitochondrial matrix
