Question

Quizplus · Accepted Answer

The physical stimuli for the sense of taste are chemical substances that are soluble in water. When we consume food, the molecules dissolve in saliva and come into contact with the taste buds, which are located on the tongue and in the mouth. These molecules then bind to specific receptors on the taste buds, which send signals to the brain to interpret the taste.

Note: Choice A (insoluble in water) is not correct because these substances would not be able to dissolve in saliva and therefore would not come into contact with the taste buds. Choice C (vibrations of molecules) is incorrect because this describes the physical stimuli for the sense of hearing, not taste. Choice D (tactile stimulation) is incorrect because this refers to the sense of touch, not taste.
