Why does saliva help us taste our food?
c.Because it helps break down our food into chemicals that we can sense

Which of the following statements is true?
b.Taste is well developed in infants
The idea of the gatekeeper function of taste is illustrated by the association of sweetness with compounds that have _____.

c. orbitofrontal cortex
Leo and Mindy have just tasted a salad. Leo maintains that the greens in the salad are very bitter, while Mindy continues to enjoy the salad. Their different reactions seem to be a result of differences in the types and numbers of taste receptors, which causes them to have different _____.
