1 . Suppose a population of bacteria, called “ population
A ”, ARE exposed to an antibiotic that disrupts the cell wall
structure, causing the bacteria to lyse (die). Another population
of bacteria, called “ population B ”, ARE NOT exposed
to any antibiotics. Over time, a small sub-population of
population A is observed to survive the antibiotic. When
researchers examine the sub-population, they find an antibiotic-
resistant gene, responsible for their survival. However, when they

investigate population B, no such antibiotic-resistant gene is
found.
How would modern evolution theory explain the difference in
resistance?
A. When population A is exposed to the antibiotic, it causes
the population to develop a helpful gene mutation in
order to survive. Since Population B was not exposed to
the antibiotic, no such gene was needed and therefore
was not found.
B. Mutations that offer resistance to antibiotics have likely
occurred in both populations (A & B). Individuals in
population A with the mutation conferring resistance
have a survival advantage compared to those without
the mutation, whereas those in population B with the
mutation conferring resistance do not have a survival
advantage when compared to those without the
mutation. Therefore, the antibiotic resistant gene is found
in population A but not population B.
C. It was possible for both populations (A & B) to develop
the mutation. But since population A was exposed to the
antibiotic, it increased the likelihood of developing a
helpful antibiotic resistant gene, whereas population B
was not exposed to the antibiotic, so the probability of
developing an antibiotic resistant gene did not change.
Due to the difference in probabilities, population A
developed the resistant gene, whereas population B did
not.
D. The antibiotic resistant gene should be found in
Population B NOT Population A, so a mistake must
have occurred in the experimental process.

2 . Unlike other types of infections, viral infections are
particularly difficult to treat with vaccines, since variants of the
virus develop so easily and quickly. One example of this is with
COVID-19 and the many variants including Omicron which had
many mutations in certain proteins, making it more easily
transmittable, even with vaccinated individuals.
What about viruses, such as HIV, make them so hard to treat
or to develop vaccines for?
1 . They are unlike human cells
2 . They do not contain genes
3 . They use forward transcription
4. They have high rates of mutation
A. 1, 2, and 3
B. 1 and 3
C. 2 and 4
D. 4 only
E. All of 1, 2, 3, and 4 are correct

3. What structure or process in cells is NOT also a characteristic
of viruses?
1. Nucleic acid genome
2. Cytoplasm
3. Reproduction or replication
4. Ribosomes
A. 1, 2, and 3
