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.

Recently, crops of vegetables such as lettuce and green onions have been contaminated, while they are still on the farm, with bacteria that cause food poisoning. how will science influence the way the government responds to prevent an increase in food-borne diseases? because science has shown that lettuce and green onions are not nutritionally valuable, the government may pass laws that ban the sale of lettuce and green onions. because science has shown that there is no way to prevent bacterial contamination, the government may pass laws that punish businesses that buy lettuce and green onions. because science has shown that the washing of hands prevent the spread of infectious diseases among people, the government may pass laws that require hand washing by everyone who handles food. because science has shown there are ways to find the source of the contamination, the government may pass laws that require farm practices that reduce the contamination of lettuce and green onions.
