Which of the following species of Clostridium produces a toxin that binds to neuromuscular junctions and prevents the release of acetylcholine, causing muscle paralysis?

The cervical lymph nodes should be palpated:

Pyroderma and erysipelas is caused by which bacterial species? 

Your TAs have just graded the current exam and submit the grades to the professor. The grades have already been sorted increasingly and stored in an array A. Out of curiosity, the professor wants to know how many students get a specific grade x. Denote the number of students as n, which is assumed to be a power of 2. Take A and x as input, your task is to design a divide and conquer algorithm such that it outputs the number of students who get grade x. Explain your design with words (no pseudocode!) and justify its correctness. Stat and analyse its runtime. Faster (and correct) solutions are worth more credit.

Why does use of broad-spectrum antibacterial drugs increase the likelihood of a patient developing an opportunistic infection with C. diff?
