Below are the questions for the exam with the choices of answers:
Question #1
A Bacteria are becoming resistant to antibiotics much more slowly than humans can invent new antibiotics.
B Bacteria can mutate in order to be immune to antibiotics.
C It takes decades or longer for organisms to evolve by natural selection.
D Resistance alleles in the bacterial populations in the human body are in Hardy-Weinberg equilibrium.
E Humans have provided the selection pressure that results in more harmful strains of bacteria.
Question #2
A not a heritable trait.
B a strong predictor of adult weight.
C subject to stabilizing selection.
D subject to directional selection.
E subject to disruptive selection.
Question #3
A The basic shapes of fish, penguins, and dolphins are vestigial structures.
B Parallel evolution is common among aquatic mammals.
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 #4
A very similar DNA
B none of these, their is no relationship between DNA and relatedness
C very different DNA
D very different proteins
Question #5
A that confer a reproductive advantage.
B that are adaptive.
C that are heritable.
D that are acquired in an individual’s lifetime.
E that reduce mortality.
Question #6
A organisms that are stronger.
B more intricate adaptations.
C organisms that are perfectly adapted to their environments
D uniformity.
E None of the above is correct.
Question #7
A Only choices a) and c) are correct.
B 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.
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 increases the genetic variability within a population.
E Migration of individuals into a population generally decreases the genetic variability within a population.
Question #8
A it must be in an unstable environment.
B the mutation rate must be low.
C individuals must be migrating in and out of the population.
D it must have a small population size.
E its members must possess inheritable variation.
Question #9
A STIs are annoying and uncomfortable but they are never fatal.
B STIs can only be transmitted through sexual intercourse.
C Genital herpes can be treated and cured with antibiotics.
D STIs can be transmitted through the mouth or the anus.
E Nearly all STIs have severe and obvious ongoing symptoms.
Question #10
A sperm; menstruation
B none of these is correct
C sperm; ovulation
D testosterone; menstruation
E testosterone; ovulation
Question #11
A uterus; oviduct
B vagina; uterus
C vagina; oviduct
D cervix; uterus
E uterus; ovary
Question #12
A urethra
B prostate
C epididymis
D seminal vesicles
E bulbourethral glands
Question #13
A organogenesis
B blastulation
C gastrulation
D fertilization
Question #14
A The offspring of sexual reproduction are genetically different.
B Finding a mate can consume lots of energy and time.
C The offspring are better suited to survival in a changing environment.
D None – all of these are advantages.
