Question

1. which of the following factors will most increase the rate at which a bacterial population develops antibiotic resistance?

○ environmental temperature
○ the bacteria’s size and shape
○ exposure to antibiotics (medications)
○ the amount of dna their parent bacteria has

Explanation:

Antibiotic resistance in bacteria develops mainly due to natural selection. When bacteria are exposed to antibiotics, those with mutations that confer resistance survive and reproduce, increasing the resistant population. Environmental temperature, bacteria’s size/shape, and parent’s DNA amount don’t directly drive resistance development as exposure to antibiotics does.

Answer:

C. Exposure to antibiotics (medications)
