Answer 1

Explanation:

When an animal cell is kept in distilled water, i.e. in the hypotonic solution for a longer time, the water will move into the cell by the process of endosmosis, which will cause swelling of the cell. After the maximum amount of water enters the cell, the cell bursts as it can no longer absorb water.

The wall of the large intestine is lined with simple columnar epithelium. Instead of having the evaginations of the small intestine (villi), the large intestine has invaginations (the intestinal glands).

Answer 2

the inner surface of large intestine is lined with mucosa .
