Answer 2

a. is increased when nostrils are closed

Explanation:

• The frogs are amphibians that is they can live in both land as well as in water.
• The frogs are able to respire through their nostrils, skin and lining of the mouth.
• The respiration through lining of the mouth is called as buccopharyngeal respiration. This can occur when the frogs are not submerged in water.
• The lining of the mouth can be used to obtain the oxygen and transferring the oxygen to the bloodstream.
• Thus the oxygen directly enters into the blood capillaries.
• The effect of such respiration will get enhanced when one of the sense organ that are nostrils which are ideally responsible for obtaining the oxygen from air get closed.
