AIts nutrients are finally absorbed
BIt is broken down by stomach acid
CIt is returned to the small intestine
DMost of its water is reabsorbed
Answer & Solution
Correct answer: D. Most of its water is reabsorbed
1. Undigested food material passes into the colon after the small intestine.
2. There most of the water it still contains is reabsorbed.
3. That leaves a semi-solid waste rather than a liquid one.
4. The colon also hosts the intestinal flora that assist digestion.
