Over the past several decades, natural selection has caused populations of
Staphylococcus aureus (a type of bacteria that causes infectious wounds)
to evolve resistance to most antibiotics. If antibiotic use were stopped,
what would you predict would happen to these S. aureus populations? *
m
O
They will go extinct without the antibiotic
O
The frequency of resistant forms will increase in these populations
The populations will begin colonizing new environments
The frequency of nonresistant forms will increase in these populations
