Question

how many nostrils do you have?​

Answer 1

Answer:

Answer 2

$\large\fbox\red{Answer}$

Two nostrils

The short answer is two nostrils provide a better sense of smell than just one. Studies have found that one nostril will generally operate better than the other on any given day. Thus, two nostrils provide a better ability to detect scents than one.
