Question 1
The phrase “survival of the fittest” is somewhat misleading because it implies that:
Answer: C. The best possible organism will evolve
Question 2
Choose the best answer. The logic of natural selection predicts that a population of organisms
will undergo evolution if, and only if, which of the following condition(s) exist?
Answer: D. Both b and c.
Question 3
Your friend was diagnosed with strep throat 2 months ago. She was treated with antibiotics for
10 days, but 2 weeks after treatment, the symptoms returned. She was given a different
antibiotic, and her symptoms again initially improved but then got worse. What is happening?
Choose the best answer.
Answer: D. Your friend was originally infected with bacteria that are resistant to at least two
antibiotics.
, Which of the following occurs after the creation of a new allele?
Answer: A. The gene pool becomes more diverse.
Question 5
A biologist has been studying two populations of trout in Montana for the last 25 years, when the
two populations were established from one common population. In the southern population, the
fish now have a slightly different mouth shape. But the northern population hasn’t changed from
the original type. The new shape works well in catching the type of prey common in the habitat
of the southern population. Which explanation is the most likely explanation of the gene
differences in the two populations?
Answer: B. The gene that produces the variation is probably still present in a small percentage of
the northern population, but since there’s no advantage to having it, individuals with the variation
aren’t preferentially selected.
Question 6
A key prediction/implication of evolutionary theory is that:
Answer: D. The frequency of alleles in a population changes over time in response to the
environment
