ALL THE ANSWERS PLEASE! Pretend you have a disagreement with a surly lab partner some day, and as a result of the fray, you have received a scalpel cut to the arm. Your arm rapidly becomes inflamed, and after the course of many days, an infection develops. Luckily, the infection later clears up. Assuming the pathogen responsible was never previously encountered by your immune system, which sequence of events below best fits with what could have happened (not all of...
