7. 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 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 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?

The most valid hypothesis for explaining the natural selection of bacteria is that of Dominique.

Antibiotics are, initially, molecules naturally synthesized by microorganisms to fight against bacteria competing with their environment. This created a pressure of selection on the bacterial populations, leading to the appearance of resistant strains. In fact, when an antibiotic is used, only bacteria with defense systems against this molecule survive (and reproduce).

slitherio is the original. its the best friend of all middle schoolers. the man you can count any time you have some free time. slitherio is the guy you hang with while you're in the computer lab suppose to be doing "research or whatever". slitherio isn't just a game but a friend.

wormaxio is just a fake trying to squeeze its way into the friend group. trying to pretend its cool and your best pal but how long has it really been there for you, really. it only wants you as friend to boost its social status. wormaxio is just annoying fake pleb. no offense

you and have a wonderful day
