Question

Quizplus · Accepted Answer

Range fractionation is a strategy in which multiple receptor cells are used to cover a larger range of stimuli instead of a single receptor cell. Each receptor cell is sensitive to only a small portion of the range, resulting in a better discrimination of stimuli. Therefore, the correct option is A.
