Question

which could best be used to explain why bacteria can infect a person very quickly?
outer capsule
binary fission
protective covering
genetic recombination

Explanation:

To determine the answer, we analyze each option:

• "Outer capsule" and "protective covering" relate to bacterial structure for protection, not rapid infection (due to quick multiplication).
• "Genetic recombination" is about genetic variation, not rapid population growth.
• "Binary fission" is the asexual reproduction method of bacteria, where one cell divides into two. This process is rapid (e.g., some bacteria divide every 20 minutes), leading to a quick increase in bacterial population, which explains why they can infect a person rapidly.

Answer:

B. binary fission
