16) Which of the following statements best explains how the sense of taste works?
Molecules of taste are absorbed through receptors on the roof of the mouth and transmitted to the stomach.
Olfactory bulbs absorb molecules of taste and then send signals to the brain.
Molecules of food fit into receptors on taste buds, and neural signals are fired to the brain.
