Cause of sneezing when one inhales air:
Air is a mixture.
There are lots of dust particles present in the air.
When an individual inhales the dust enters the nose, these particles of dust pass through the hair in the nasal cavity.
These disturbances send to the brain and create sneezing.
Sneezing also helps in expelling the dust, making the air passage clean.
Therefore, the individual sneezes when he inhales unclean air

Homework answer :- The dust-laden air is not good for us because it has germs so when this happens the information goes to the brain and we sneeze to take out the germs from our nose

Hi
Mam

[@Saiyain_Gamer]

Good morning mam
The answer is :- when we inhale a lot of dust it irritates the nose because dust has so many small particles so we throw dust from the nose by sneezing

Homework Question Answer-
Sneezing:- In case, unwanted particles are not trapped in the hair, they irritate the sensory lining of the nasal cavity. This causes sneezing and unwanted particles are thrown out.
