APFIVE Antibiotic Resistance and Natural Selection
How does the evolution of antibiotic resistance in bacteria demonstrate the principle of natural selection?
A
All bacteria in a population simultaneously develop resistance through horizontal gene transfer
B
Antibiotics directly cause beneficial mutations in bacterial DNA, leading to resistance
C
Bacteria with genetic variations conferring antibiotic resistance survive and reproduce, passing on the resistant trait to offspring
D
Bacteria actively modify their genes to develop resistance in response to antibiotic exposure
