AP BIO FINAL EXAM QUESTIONS AND
ANSWERS
the food web represented above does not include bacteria and fungi. whcih of the
following best describes a consequence of having no bacteria and fungi in the food
web? - Correct Answers -grasses will have no direct access to chemical components
recycled from dead organisms
the following DNA sequence is a small part of the coding (nontemplate) strand from the
open reading fram of the B-hemoglobin gene. Given the codon chart listed below, what
would be the effect of a mutation that deletes the G at the beginning of the DNA
sequence? - Correct Answers -the reading frame of the sequence would shift, causeing
a change in the amino acid sequence after that point
which of the following questions might scientists ask to most reliably determin if there
has ever been life on Mars? - Correct Answers -did Mars have elements present in its
atmosphere to support life?
Cortisol is a hormone produced in response to stress, including starvation, in humans.
Which of the following is most likely an immediate effect of a starvation induced
increase in cortisol secretion? - Correct Answers -increased mobilization of gatty acids
from fat cells
which of the following is the most likely consequence of adding ciproflozacin to animal
feed? - Correct Answers -ciprofloxacin resistant strains of C. jejuni will have a selective
advantage in the digestive tracts of livestock, increasing the risk of serious infection in
people
the table above shows derived characters for selected organisms. Based on the
information in the table, which of the following cladograms best represents the
evolutionary relationships among the organisms? - Correct Answers -Fish breaks off
first
damaged tissue releases chemicals that activate platelets and stimulate the formation of
blood clots. WHich of the following predictions about the activity of platelets best
describes a positive feedback mechanism? - Correct Answers -activated platelets
release chemicals that activate more platelets
based on the results of the experiment, which of the following types of molecules did the
bacteriophages most likely inject into the bacteria cells? - Correct Answers -DNA
, which of the following conclusions is best supported by the results of the experiment? -
Correct Answers -neither population grows as large when cultured together as each
does when cultured separately
bacterial cells that contain green fluorescent protein (GFP) will fluoresce under
ultraviolet light. Which of the following is the most likely outcome of replacing the lacZ
gene in the E. coli lac operon with the gene encoding GRP? - Correct Answers -beta
galactosidase will be made only when bacteria are cultured under ultraviolet light
which of the following predics the most likely outcome of moving a population of guppies
from a pool with pike cichilids to a pool with killifish? - Correct Answers -after many
generations, the offspring of the introduced guppies will mature at an older age and
larger size because of selective pressure from the new predator
which of the following questions will best direct an investigation of the mechanism of
ATP synthase? - Correct Answers -is the phosphorylation of ADP by ATP synthase
dependent on the formation of a proton gradient?
the difference in carrying capacity between the two species when cultured separately is
closests to which of the following values? - Correct Answers -350 individuals per 5.0 mL
which of the following statements best justifies th euse of the experimental results in an
investigation of interspecies competition? - Correct Answers -when two populations use
the same sources of energy, resource availability in a shared environment limits the
growth of both populations
if the mixed populations were cultured for an additional 25days, which of the following
predictions would be consistent with the data? - Correct Answers -one population would
stabilize at a large size, and the other population would be eliminated from the culture
based on the experimental results, which of the following statements best describes the
relationship of the two populations that were studies in the investigation? - Correct
Answers -the populations have a competitive relationship in which each species limits
the ability of the other to reproduce
Percent of moths recaptured in two different environments which of the following claims
is best supported by the data? - Correct Answers -dark colored moths were more likely
to be recaptured in the polluted environment than in the unpolluted environment,
suggesting an increased chance of reproductive success
which of the following question about the origin of life on Earth is most scientifically
testable? - Correct Answers -can simple organic molecules form spontaneously in an
oxygen free atmosphere
a microelectrode is inserted into a neruon. A voltage recorder then measure the voltage
difference between the microelectrode inside the cell and an electrode placed outside
the cell. Which of the following plots most accurately represents the changes in
