Will give brainliest to a clear explain answer.

Which receptor listed DOES NOT adapt?

a. olfactory receptor

b. internal thermoreceptor

c. external thermoreceptor

The right answer is internal thermoreceptors

The olfactory receptor adapts to the external environment in which we are, for example, when we put perfume on ourselves, we feel it at the beginning and then we do not smell it anymore.

External thermoreceptors such as those located in the hand adapt to the temperature to which it is in contact. When we put our hands on a cold object we just feel it at the beginning.

The good example to explain the non-adaptability of the internal thermoreceptors is when you have a fever, for several days you have this sensation of heat inside our body. It disappears only when the temperature drops
