Question #6

A.
Genital herpes can be treated and cured with antibiotics.
B.
Nearly all STIs have severe and obvious ongoing symptoms.
C.
STIs can be transmitted through the mouth or the anus.
D.

Question #7
For a population to evolve through natural selection:
A.
individuals must be migrating in and out of the population.
B.
the mutation rate must be low.
C.
its members must possess inheritable variation.
D.
it must have a small population size.
E.
it must be in an unstable environment.
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 increases the genetic variability within a population.
B.
Migration of individuals into a population generally decreases the genetic variability within a population.
C.
Only choices a) and c) are correct.
D.
Migration of individuals into a population generally causes that population to diverge to the extent that it becomes a new species.
E.
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.
Question #9
Evolutionary change as a result of natural selection ALWAYS leads to:
A.
organisms that are perfectly adapted to their environments
B.
more intricate adaptations.
C.
uniformity.
D.
organisms that are stronger.
E.
None of the above is correct.
Question #10
Natural selection can only act on traits:
A.
that are heritable.
B.
that reduce mortality.
C.
that confer a reproductive advantage.
D.
that are adaptive.
E.
that are acquired in an individual's lifetime.
Question #11
If two organisms are closely related, we would expect them to have:
A.
very different proteins
B.
very different DNA
C.
very similar DNA
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 basic shapes of fish, penguins, and dolphins are vestigial structures.
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 similarities are probably due to random chance.
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.
not a heritable trait.
B.
a strong predictor of adult weight.
C.
subject to directional selection.
D.
subject to disruptive selection.
E.
subject to stabilizing 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 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.
Bacteria can mutate in order to be immune to antibiotics.
