Question

1. which of the following explains why bacteria populations are able to become antibiotic resistant so quickly?

they have so many types of proteins.
they have so much dna.
their reproduction is simple and fast.
they can change shapes and sizes easily.

Explanation:

To determine why bacteria become antibiotic - resistant quickly, we analyze each option:

• Option 1: The number of protein types is not the main reason for rapid antibiotic resistance. Antibiotic resistance is related to genetic changes and reproduction rate, not protein variety.
• Option 2: Bacteria have relatively small genomes (less DNA compared to eukaryotes), so having “so much DNA” is incorrect.
• Option 3: Bacteria reproduce asexually (binary fission) quickly. This rapid reproduction means that any beneficial mutation (like one conferring antibiotic resistance) can be passed on and spread through the population in a short time.
• Option 4: The ability to change shape and size easily has no direct relation to developing antibiotic resistance.

Answer:

Their reproduction is simple and fast.
