The review session for the final exam will be held on Wednesday November 29th at 6-8pm in Willamette 100. There were no questions given out for this discussion section. We discussed the midterm exam instead.
Many answers are acceptable.
One possibility is that this animal lives in an environment low in peppermint, yet peppermint is the animal's primary nutrition source. Perhaps an even better answer was created by one of the students. He suggested that the animal in question preys on another animal that lives in peppermint leaves. As the preying animal gets closer and closer to peppermint leaves, its acuity for the scent of peppermint decreases in order for it to be able to smell its prey. Again, many answers are possible, but a necessary inclusion is the existence of inhibitory neuronal hookups.
