Sample Questions with Correct
Answers
The Evolution Canyons found in Israel are natural laboratories for exploring evolution
and adaptation because _________________________ when you compare organisms
that live in both environments.
A) north-facing (European) and south-facing (African) slopes share the same
environmental conditions, so you expect to see the same adaptations
B) conditions on the north-facing (European) slope are much more variable than those
on the south-facing (African) slope, so you expect to find that organisms from the north-
slope are better adapted to harsh climates
C) conditions on the south-facing (African) slope are much more variable than those on
the north-facing (European) slope, so you expect to find organisms from the south-slope
are better adapted to harsh climates
D) Only mammals are affected by the different conditions on the north-facing
(European) and south-facing (African) slopes, so these canyons are of limited use -
ANSWERSAnswer: C
Ice floats in liquid water because:
A) ice contains air bubbles that reduce its density, making it less dense than liquid
water.
B) it is held on top of the liquid water by the high surface tension of liquid water.
C) the water molecules in ice are held further apart than the molecules in liquid water.
D) there are fewer hydrogen bonds between water molecules in ice than there are in
liquid water. - ANSWERSAnswer: C

___________________ fat and fat comprised of only this type of molecule is expected
to be _____________ at room temperature.
A) unsaturated ; solid

The polar region of this phospholipid is indicated by the letter ______ -
ANSWERSAnswer: D
A mutation in the PHEX gene leads to a form of rickets. The mutation leads to a change
in the amino acid at position 720 in the polypeptide from an Ala (normal protein) to a
Thr. What effect would you predict this mutation to have on the protein produced by this
gene?
A) It will make the protein slightly more hydrophobic.
B) It will make the protein slightly less hydrophobic.
C) It will make the protein much shorter.
D) It will not have an effect on the solubility of the protein. - ANSWERSAnswer: B
Based upon these results from a study that compared the effect of a statin alone for
three different statins (RSV, ATV, SMV) against each statin plus ezetimibe (EZE), which
of these statements are true for the percent reduction of LDL-C? The * represents a
probability (p) less than 0.0001. Choose all that apply.
A) Individuals treated with SMV, either alone or in combination, had the greatest percent
reduction in their cholesterol.
B) Individuals treated with SMV plus EZE always showed a greater reduction in their
cholesterol level than treatment with a statin alone.
C) The statin RSV is the most effective of the three statins at reducing an individual's
cholesterol level when used alone.
D) There is no statistically significant difference between treatment with a statin alone
versus SMV plus EZE for any of these comparisons.
E) Individuals treated with SMV alone had the lowest percent reduction in their choleste
- ANSWERSAnswer: B, E, F
, A paleontologist is radiometrically dating three rocks from three different sites using the
Potassium-Argon "clock", which has a half life of 1.25 billion years. The data she has
obtained is shown in the table below. Based upon these data, which rock is the oldest?
Rock being test
Amount of parent element (Potassium) present
Rock A 50%
Rock B 12.5%
Rock C 25%
A) Rock A
B) Rock B

D) You cannot determine this from the information given. - ANSWERSAnswer: B
You are examining this recent core from a pine tree in North America. It spans three
decades, 1950 to 1980. Which of the following statements is supported by the pattern of
the rings in this core?
A) The climate conditions were very consistent across all three decades.
B) The climate was cooler and drier in the 1970s than in the 1960s and 1950s.
C) The climate was cooler and drier in the 1950s than in the 1960s and 1970s.
D) The climate was very warm and wet only during the 1960s. - ANSWERSAnswer: C
You are an archaeologist who has just found an ancient fire ring containing charcoal
fragments. You send these fragments to the lab for Carbon-14 analysis. The report you
receive from the lab states that these fragments have 25% of the amount of Carbon-14
compared to modern wood. Using 5730 years as the half-life of Carbon-14, you
conclude that these charcoal fragments are about ______ years old. -
