The dots represent a bacterial infection. Sal was very sick with this bacterial infection. The infection was treated with antibiotics. Sal seemed to get well, but in a few weeks, she was sick again. How can this be explained using natural selection?

AThe antibiotics were ineffective to this strain of bacteria.

BThe stronger, more resistant bacteria survived the antibiotics and reproduced.

CThe antibiotics did not kill the bacteria; it only forced them to be dormant.

DAntibiotics will only kill a portion of the bacteria, no matter how much medicine Sal takes.

BThe stronger, more resistant bacteria survived the antibiotics and reproduced.
This situation can be explained by natural selection as the bacteria that were resistant to the antibiotics were able to survive and reproduce, passing on their resistance to future generations. Over time, the population of bacteria in Sal's body became more and more resistant to the antibiotics, leading to a recurring infection. This highlights the importance of properly completing antibiotic treatments to prevent the development of antibiotic-resistant bacteria.
