Sparky and Bailey are bacteria that represent two extremes of antibiotic sensitivity. Sparky cannot survive any exposure to penicillin at all, while Bailey can survive exposure to twice the concentration of penicillin used to treat most infections. In a healthy person who has never taken penicillin, is Sparky or Bailey most likely to survive and reproduce? Why?

Bailey is most likely to survive

Explanation:

Bailey can survive exposure to twice the concentration of penicillin used to treat most infections. In addition, this would increase the chances of Bailey surviving with the example of a healthy person who has never taken penicillin.
