Lecture 28 - Quorum sensing (participation)

I realize in the lecture I said this would be a discussion board, but we're going to do it as a quiz because student-student interaction isn't super important on this one.

Within this 'quiz' you will be asked to respond to the prompt from Lecture 28 - Quorum Sensing.

Think it over, and respond with your best guess. 

I will be grading this based on correctness (1 point) and a give-a-darn level of response (3 points).  If you're correct and you describe your rationale, you'll get the full 4 points.  Otherwise, you'll get partial credit if you're off-base or do not fully rationalize your response.
