Question

multiple choice question
which process is responsible for the evolution of antibiotic resistance in pathogenic bacteria?
the founder effect
the bottleneck effect
natural selection
binary division

Explanation:

Natural selection is the process by which organisms with traits that give them an advantage in their environment are more likely to survive and reproduce. In the case of pathogenic bacteria, some bacteria may have genetic mutations that confer antibiotic - resistance. When exposed to antibiotics, non - resistant bacteria are killed, while resistant bacteria survive and reproduce, passing on their resistance genes. The founder effect and bottleneck effect are related to genetic drift in populations and not directly responsible for the evolution of antibiotic resistance. Binary division is a form of asexual reproduction in bacteria but does not explain the evolution of resistance.

Answer:

C. Natural selection
