Answer #1

Answer: (b) The structure of the nasal cavity helps to cool down inhaled air on hot days

Rationale: when we inhale the air in the surroundings will goes to the lungs to the nasal cavity, We need air to consume the oxygen from it. So while doing it some times hot air will goes through the nasal cavity.

At that time our nasal cavity moisten the air. Because it consists of mucosa membrane. It will maintain both the hot and dry conditions.

Thus the air will get cool down, if it is too hot to enter into the respiratory system.
