Two students are discussing natural selection in bacteria and how it can relate to antibiotic resistance in bacteria.
Bernadette states that when antibiotics are used, bacteria can respond by developing traits to help them

Dominique states that there is already a variety of traits among the bacteria. Bacteria that have traits that
allow them to survive the antibiotic and reproduce may have higher fitness.
Which individual's reasoning do you agree with more and why?
