Answer:

The answer is (a) both I and iii

Answer 2

Answer:

Only III is wrong.

Explanation:

We do have three pairs of salivary glands- parotid( near ears), submaxillary ( under jaw ) and sub lingual( under tongue ) that release saliva. Saliva makes food a soft, moist mass called bolus. It releases an enzyme salivary amylase for 30 percent digestion of starch but not fat.
