Regarding the sense of taste, which statement is true?

• A. People without tongues are unable to sense taste.
• B. The receptors for taste are located mostly on the tongue.
• C. When taste receptors are "killed off" by hot foods, they remain inactive.
• D. Genetic factors do not play a large role in taste sensitivity.

Answer: (B)

The statement that the receptors for taste are located mostly on the tongue is accurate because the majority of taste buds, which contain the sensory receptors responsible for detecting taste stimuli, are found on the tongue's surface. These taste buds can also be found in smaller numbers on the roof of the mouth and in the throat, but the tongue is the primary organ responsible for taste perception. While it's true that people without tongues might experience diminished taste sensitivity, they can still detect some flavors through other means, such as through the olfactory system, which plays a significant role in flavor perception. Additionally, taste receptors can adapt and recover from overstimulation; hot foods can temporarily affect taste sensitivity, but they do not permanently "kill off" taste receptors. Genetic factors indeed play a crucial role in an individual's taste sensitivity, influencing how intensely different tastes are perceived by different people.
