Answer 2

Answer:

Receptors for the sense of smell are located at the upper end or at the top of the nasal cavity.

Explanation:

One can smell any thing due to the sensory receptors that recognise the chemicals present in air.

These are also called chemo receptors.

This tissue is in the size of a postal stamp.
