Tanya Hahn · Answer 1

a. are quick to adapt to a particular stimulus intensity.

Explanation:

Phasic receptors are the one that first generates an action potential in response to the stimulus. However, they adapt to that intensity of the first stimulus and reduce signaling. Slowly, they even stop signaling irrespective of the presence of stimulus of the same intensity.

This is the reason that we get adapted to the specific odor such as gas leakage after some time even if the leakage continues.
