Question

how can we detect the smell of an agarbatti (incense stick ) in 1 mark ​

Answer 1

Explanation:

It is so because the particles of incense stick get mixed with air and as we all know the particles move from high concentration to lower concentration through diffusion. Hence, due to this we can detect the smell of incense stick.

Answer 2

The smell of agarbatti diffuses in the air . It is detected by olfactory receptors present in the nose . This information is sent to olfactory lobe by sensory nerves located in the forebrain which further responds to the information .
