Answer:

Option). the mucus coating secreted by the epithelial cells of the stomach

Explanation:

Stomach produces gastric juices, which is very acidic in nature, due to hydrochloric acid.

In normal conditions, surface epithelial cells of stomach are present in stomach inner wall, which are mucus-producing cells. These cells secret mucus and protect the inner side of stomach from concentrated gastric acid.

Stomach ulcers are sores in stomach wall, due to break in its inner lining by gastric acid, due to inhibition of mucus secretion due to various factors.

Thus, the correct answer is second option.

victus00 [196]

Answer:

The correct answer will be option-C.

Explanation:

The race is a term used to denote the group of people who share common ancestors and descended from it. The groups are based on the physical appearance and social qualities as a result of adaptation and natural selection which led to the variation in the species of humans.

Although humans show variation, they all belong to the same species and same genus- Homo sapiens. The sapiens share 99% DNA as well they can successfully reproduce with each other which shows that they have descended from a common ancestor.

Thus, Option-C is the correct answer.
