Maria has a sore throat. her father takes her to the doctor and she is given an antibiotic. after ten days, maria is still sick. use the model seen here and describe what has happened to maria in terms of natural selection.

The answer to this question would be: Some of the bacteria are resistant to the antibiotic. They survive and reproduce, keeping Maria sick.

In this case, the bacteria that infect Maria vary in the level of resistance to the antibiotics. When antibiotic administered, the bacteria with a low level of resistance killed but bacteria with a high level of resistance survive. These bacteria continue the infection so Maria is still sick.

B. would complete your answer. give me brainliest!

Where are the options?
