An individual is exposed to a pathogen and takes five days to recover. When exposed a year later they again take five

days to recover. Would you suspect that adaptive immunity was involved? Why or why not? What will be an ideal response?


ANSWER: No, in cases where adaptive immunity is involved the recovery to the second exposure would
be much quicker. It is likely that innate immune responses were involved.
