Question #7
For a population to evolve through natural selection:
A.
it must have a small population size.
B.
the mutation rate must be low.
C.
it must be in an unstable environment.
D.
its members must possess inheritable variation.
E.
individuals must be migrating in and out of the population.
Question #8
Select from the choices below the statement that best describes the effect of the migration of individuals into a population.
A.
Migration of individuals into a population generally decreases the genetic variability within a population.
B.
Migration of individuals into a population generally increases the genetic variability within a population.
C.
Migration of individuals into a population generally causes that population to diverge to the extent that it becomes a new species.
D.
Migration of individuals into a population generally causes no change in the genetic variability within a population because it is a case of artificial selection.
E.
Only choices a) and c) are correct.

organisms that are stronger.
B.
more intricate adaptations.
C.
uniformity.
D.
organisms that are perfectly adapted to their environments
E.
None of the above is correct.
Question #10
Natural selection can only act on traits:

that are adaptive.
B.
that confer a reproductive advantage.
C.
that reduce mortality.

If two organisms are closely related, we would expect them to have:
A.
very different DNA
B.
very similar DNA

Question #12
The fact that fish, penguins, and dolphins all have the same basic shape is BEST explained by which of the following?
A.
Parallel evolution is common among aquatic mammals.
B.
The similarities are probably due to random chance.
C.
Divergent evolution and adaptive radiation into new niches often result in convergent evolution.
D.
The basic shapes of fish, penguins, and dolphins are vestigial structures.
E.
Fish, penguins, and dolphins all faced the same physical constraints during their evolution and converged upon the same body plan.
Question #13
Exceptionally large babies increase a mother's mortality risk when giving birth and exceptionally small babies tend to die at birth or shortly afterward. For these reasons, birth weight in human babies is generally:

a strong predictor of adult weight.
B.
subject to stabilizing selection.
C.
subject to disruptive selection.

not a heritable trait.
E.
subject to directional selection.

The rise of antibiotic-resistant bacteria demonstrates which of the following?
A.
Bacteria can mutate in order to be immune to antibiotics.
B.
Resistance alleles in the bacterial populations in the human body are in Hardy-Weinberg equilibrium.
C.
Bacteria are becoming resistant to antibiotics much more slowly than humans can invent new antibiotics.
D.
It takes decades or longer for organisms to evolve by natural selection.
E.
Humans have provided the selection pressure that results in more harmful strains of bacteria.
