BIO 1500 FINAL EXAM PREP
1. True or False: Bacteria possess a nuclear envelope that surrounds their chro-
mosomes, keeping their DNA separate from the cytoplasm.: false
2. True or False: chromosome replication is required for reproduction.: true
3. Which of the following provides the correct sequence of events during in-
terphase and mitosis?: DNA replicates, nuclear membrane dissolves, spindle fibers attach to centromeres,
mitotic spindles pull chromatids to opposite poles
4. Honeybees are important pollinators of many cash crops and are necessary
for high yield. A farmer in New York noted that the honeybees on his farm were
all found dead underneath windows and concluded that they were running into
windows and dying. Based on this observation, he recommended that no farm
buildings should have windows. This is an example of:: inductive reasoning

,5. The frequency of antibiotic-resistant bacteria has been increasing at an aston-
ishing rate and projections are that they could kill as many as 40 million people
by 2050. One group studying the situation has asked, "When did antibiotic
resistance become common?" This represents:: a descriptive question
6. The frequency of antibiotic-resistant bacteria has been increasing at an as-
tonishing rate and projections are that they could kill as many as 40 million
people by 2050. Another group focused on antibiotic resistance in bacteria
designed experiments to determine if two common bacteria, Staphylococcus
aureus (MRSA) and Clostridium difficile (C. diff), are resistant to antibiotics. They
were able to resurrect samples of these two bacteria from samples frozen in the
1950s and compared their antibiotic resistance with present day strains (2024).

, Comparisons of growth rate strains showed that 2024 strains of MRSA and C.
diff grew 10x and 8x more, respectively, than strains from the 1950s. Statistical
analysis of these differences yields probabilities (P-values) for the comparison
with 1950s strains: MRSA, 1950s vs 2024, P = 0.01, C.diff, 1950s vs 2024, P =
0.03. Based on these results you would conclude that:: Both evolved antibiotic resistance.
7. (Fill in the blanks) There are several disadvantages to sexual reproduction,
yet it is the primary mode of reproduction in animals. This is because lev-
els of genetic variation are higher when organisms reproduce due to
.: sexually, independent assortment
