Question 2

Pick a biological situation where a positive feedback loop controls a response. Show how this loop operates to bring about the response.

Accepted Answer

Most of the possible responses are those involving development or reproduction. Possible examples are:1) courtship and mating, 2) molting of the cuticle in insects, 3) metamorphosis in insects, frogs, or any animal with a larval form, 4) childbirth, intercourse and orgasm, a sneeze, nerve impulse transmission. Any process that involves a directional change can qualify. A complete answer should include information showing that the animal passes through this directional change in controlled stages, sensing the completion of one step before proceeding to the next.
