Question 24
When a person is suffering from severe cold, he or she cannot

(a) differentiate the taste of an apple from that of an ice cream
(b) differentiate the smell of a perfume from that of an agarbatti
(c) differentiate red light from green light
(d) differentiate a hot object from a cold object

Answer 1

(b) differentiate the smell of a perfume from that of an agarbatti

During the cold, our brain does not receive the signal to identify the perfume because mucous of our nose becomes thick that blocks the passage from where odour and air molecules reach the receptor cells of the olfactory nerves.
