Within a population of field mice, some individuals have brown fur and some have
white fur. How would the population be affected if a change in the environment causes
natural selection to favor the white-furred mice?
A
The brown-furred mice would begin to grow white fur.
B
The white-furred mice would kill off the brown-furred mice.
C
The brown- and white-furred mice would begin to produce more offspring with
white fur.
D The brown-furred mice would be less likely to survive to produce offspring with
brown fur.

The study of the fossil record provides evidence of evolution and common ancestry. A
very large fraction of all fossils discovered have been found in sedimentary rock. This
rock is deposited in layers, one on top of the other. The fossils are embedded within
the different layers.
In sedimentary rocks, fossils in the lower layers represent fossils that are
_______________ fossils in the upper rock layers.
F
the same age as
G more closely related
H younger than
J
older than

A certain species of rabbit has either white (F) or brown fur (f) and either a round (T)
or square tail (t).
White fur is dominant to black fur and a round tail is dominant to a square tail.
A cross is performed with one rabbit that is homozygous dominant for both traits and
a second rabbit that is homozygous recessive for both traits. If one offspring is picked
at random, what is the most likely genotype that it will have?
F
The rabbit will be homozygous dominant for both traits.
G The rabbit will be homozygous dominant for fur color, but heterozygous for tail
shape.
H The rabbit will be heterozygous for both traits.
J
The rabbit will be heterozygous for fur color, but homozygous dominant for tail
shape.

Look at the food chain on the right. Which of the following statements about the
movements of energy in the food chain is TRUE? Assume that there are no other
organisms in this ecosystem.
A
Most of the energy the deer obtains from the shrubs is passed onto the wolves
later.
B
Energy must pass to the shrubs before it can be obtained by the deer.
C
When they die, the energy in the deer return to the shrubs.
D The only relationships between the wolf and the sun is that the wolf can obtain
energy directly by sunning itself.

To the right is a picture of two organisms that have an ecological relationship. Use this
picture and the information below to answer the question that follows.
Ants collect food on the forest floor. Sometimes, an ant will pick up fungus cells while
scavenging. The fungus grows inside the ants, releases chemical signals, and
eventually takes over the ant's behavior. The ant climbs onto the underside of a leaf
and latches on. As the ant dies, the fungus produces a spore-bearing stalk. The spores
are released and fall below to be picked up by new ants.
What relationship exists between the ants and the fungus?
F
commensalism
G parasitism
H mutualism
J
predation

Which of the following is NOT a true statement about the process of DNA replication?
F
DNA replication is needed so that a new cell receives a copy of the DNA.
G DNA replication occurs within the nucleus of the cell.
H Each new double helix of DNA contains one strand from the original molecule and
one newly created stand.
J
In the last step DNA replication, the two strands of DNA "unzip."
