AP BIO MOCK EXAM QUESTIONS
AND ANSWERS
Thirds feed on rose pollen. Scientists noted that the thirds population increased in the
spring and decreased dramatically during the summer. The researchers hypothesized
that food abundance was the limiting factor for the population. Which type of data would
be most useful for the scientists to collect at regular intervals on a designated test plot
of rose plants? - Correct Answers -Density of rose pollen produced (g/m^2)
NOT: The amount of pollen produced by each flower
Undersea landslides can disrupt marine habitats by burying organisms that live on the
ocean floor. The population in the graph was affected by a recent landslide. What is the
best prediction on how the population will be affected by the landslide? - Correct
Answers -The reduced population will likely have allelic frequencies that are different
from the initial population.
NOT: The population will adapt to deeper waters to avoid future landslides.
Describe the Calvin Cycle - Correct Answers -The reactions of the Calvin cycle add
carbon to a simple five-carbon molecule called RuBP. These reactions use chemical
energy from NADPH and ATP that were produced in the light reactions. The final
product of the cycle is glucose.
What is apoptosis? - Correct Answers -Apoptosis involves the regulated activation of
proteins in specific cells of the developing forelimb that leads to the death of those cells.
"Programmed cell death"
What is pre-zygotic isolation? - Correct Answers -It is a type of reproductive isolation
that occurs before the formation of a zygote can take place. In most cases mating does
not even occur.
The observation that the rabbit mRNA was successfully translated in the frog tissues
supports which conclusion? - Correct Answers -Rabbits and frogs share a common
genetic code for expressing heritable information.
NOT: Frog cells are able to replace their own hemoglobin with rabbit hemoglobin.
Which conclusion is most consistent with the results of the experiment? - Correct
Answers -The subunits of hemoglobin differ in size, shape, or charge.
