Question

1. Hydrochloric acid is present in the stomach.
2. Assimilation is completed in the small intestine​

Answer 1

Explanation:

Hydrochloric acid is present in the stomach

The hydrochloric acid in the gastric juice breaks down the food and the digestive enzymes split up the proteins. The acidic gastric juice also kills bacteria. The mucus covers the stomach wall with a protective coating.

Assimilation is completed in the small intestine

Moreover, in the small intestine, the complete digestion process occurs in the duodenum, followed by 90% of the assimilation of nutrients including protein, carbohydrates, vitamins, and minerals is achieved in the jejunum.
