Imagine you are a biologist who is working with a colony of 100 billion bacterial cells. This colony is entirely descended from a single bacterial cell that was not resistant to penicillin. You treat the colony with penicillin and eventually find that one of the cells is able to resist the effects of penicillin. Explain how that cell could be resistant if the first cell in the colony was not.

the cells over time had grew to resist penicillin and that is why they are resistant

Explanation:

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
