Question

At the beginning, there was variation in the bacteria population in which both resistant and non-resistant bacteria existed.


True


False

Answer 1

True. In a bacterial population, there is often genetic variation, which can include differences in resistance to antibiotics. Some bacteria may possess genes that confer resistance, while others do not. This variation is a key factor in the process of natural selection, as antibiotic pressure can lead to a higher survival rate for resistant bacteria.
