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.
its members must possess inheritable variation.
D.
it must be in an unstable environment.
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 causes no change in the genetic variability within a population because it is a case of artificial selection.
B.
Migration of individuals into a population generally decreases 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.
Only choices a) and c) are correct.
E.
Migration of individuals into a population generally increases the genetic variability within a population.
Question #9
Evolutionary change as a result of natural selection ALWAYS leads to:

organisms that are perfectly adapted to their environments
B.
uniformity.
C.
more intricate adaptations.
D.
organisms that are stronger.
E.
None of the above is correct.
Question #10
Natural selection can only act on traits:
A.
that reduce mortality.
B.
that are acquired in an individual's lifetime.
C.
that are adaptive.
D.
that are heritable.
E.
that confer a reproductive advantage.
Question #11
If two organisms are closely related, we would expect them to have:
A.
very similar DNA
B.
very different DNA
C.
very different proteins
D.
none of these, their is no relationship between DNA and relatedness
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.
Fish, penguins, and dolphins all faced the same physical constraints during their evolution and converged upon the same body plan.
D.
Divergent evolution and adaptive radiation into new niches often result in convergent evolution.
E.
The basic shapes of fish, penguins, and dolphins are vestigial structures.
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:

not a heritable trait.
B.
subject to stabilizing selection.
C.
a strong predictor of adult weight.
D.
subject to disruptive selection.
E.
subject to directional selection.
Question #14
The rise of antibiotic-resistant bacteria demonstrates which of the following?
A.
Resistance alleles in the bacterial populations in the human body are in Hardy-Weinberg equilibrium.
B.
Humans have provided the selection pressure that results in more harmful strains of bacteria.
C.
Bacteria can mutate in order to be immune to antibiotics.
D.
It takes decades or longer for organisms to evolve by natural selection.
E.
Bacteria are becoming resistant to antibiotics much more slowly than humans can invent new antibiotics.
