Answer 1

False

Question 2

What is the function of the basal cells of the taste buds?

A) They are the taste receptor cells.
B) They transmit sensory impulses from the taste receptor cells to the 3 cranial nerves associated with gustation.
C) They surround and protect the taste buds.
D) They replace damaged taste cells every 7-10 days.
E) They provide physical support to the taste receptor cells.

Answer 2

D
