Question
How do we detect the smell of an agarbatti (incense stick)?
Advertisements
Solution
When the smell of the incense stick reaches our nose, then the factory receptors present in our nose detect it and send this information to the forebrain in the form of electrical signals. The brain interprets this information as the smell of incense sticks where it is already stored.
