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 defeat the antibiotic, which then may increase their fitness. Dominique states that there is already a variety of traits among the bacteria. Bacteria that already have traits that allow them to survive the antibiotic will reproduce at a faster rate. Is either student correct? Are both incorrect? Respond to both students' claims using plenty of evidence.
