in a population of sexually reproducing bacteria how can we select for the resistant ones by only taking antibiotics for 2 days
VladimirAG [237]

We can select the resistant microbes that were survived on the second day of antibiotic application.

<h3>How can we select for the resistant ones?</h3>

We can select for the resistant ones by only taking antibiotics for 2 days instead of the full 10 days that the drugs were prescribed in order to see the microorganism that survived on the second day. Bacteria get resistance when they are exposed to similar type of chemicals for a long time. Some of bacteria mutate and make defenses against the chemical which leads to survival of that organism.

So we can conclude that We can select the resistant microbes that were survived on the second day of antibiotic application.
