Answer to Question 1

Answer: Potassium ions would leave the cell, making the interior even more negative. This in turn would limit the excitability of the nerve cell.

Answer to Question 2

Answer: Because the blood-brain barrier is weak near this structure, toxins in blood can stimulate this brain region to cause emesis, which would void the stomach and in turn may reduce the total amount of toxicity to the organism.
