Journal Entry:

If you were to place a sugar cube in your mouth, the sugar would dissolve in your saliva. Some of the molecules of sucrose would attach to specific taste receptors on your tongue. This produces a signal to the brain of a sweet taste. Eventually, the sweet taste will fade. Why do you think the perception of sweetness wears off after a certain span of time?
