You have Strep Throat—Streptococcus pyogenes. This is a bacterial infection transferred through airborne droplets, sneezes, coughs, and sharing of foods and beverages. A doctor prescribes the antibiotic Amoxicillin and tells you to take it twice daily for ten days. After only six days you are feeling better, so you stop taking the medication. Within a few days you become violently ill—another, more severe case of Strep Throat. You try taking the rest of your Amoxicillin, but it appears to do nothing at all. Which statement best describes why the Amoxicillin is no longer killing the bacteria.
The amoxicillin still works just as effectively as before, but you need to take it for at least six days
before the bacteria will die.
The bacteria gained the ability to fight off Amoxicillin. This acquired trait is now passed on to offspring
as the dominant characteristic in the new population of Streptococcus pyogenes.
The majority of bacteria died, but some bacteria had mutated DNA that allowed them to resist the
effects of Amoxicillin. This mutated DNA was passed on creating a stronger population of
Streptococcus pyogenes.
Because bacteria don’t have an immune system, so they cannot establish a resistance to antibiotics.
However, the human body can transfer resistance to medications to bacteria on accident through
normal physiological processes.

If a new river forms, splitting an ecosystem in half, what is likely to occur over time?
Divergent evolution, resulting in speciation.
Elimination of all species.
Increased stability of current populations.
Bird populations will no longer interbreed, so new species of bird will form.
