Question

what is the evolutionary process that causes antibiotic - resistant bacteria to increase and antibiotic - sensitive bacteria to decrease in an environment where antibiotics are present?
○ bacterial selection
○ environmental selection
○ evolutionary selection
○ natural selection
○ antibiotic selection

Explanation:

The process where antibiotic-resistant bacteria survive and reproduce (increasing their numbers) while sensitive bacteria die (decreasing their numbers) in an antibiotic-containing environment is natural selection. Antibiotics act as a selective pressure favoring resistant traits, which is a classic example of natural selection.

Answer:

natural selection
