Quizplus · Accepted Answer

As more and more antibiotics are prescribed natural selection acts on the bacterial populations to select for those that have a resistance. Typically antibiotics act on some molecule in the bacterium such as an enzyme that plays an important role in the bacterium's functioning. Bacteria that have a mutation in this molecule are not susceptible to the antibiotic and are the ones that survive and pass on this mutation to future generations. Over time, more and more of the population have the mutation and eventually the antibiotic will no longer affect the bacterial population.Bloom's
