Answer:
D.) Water is recovered.
Explanation:
Large intestine is a part of alimentary canal. The food gets digested by the time it reaches here. So large intestine has no role in digestion. Its main function is to absorb water from the remaining undigested food matter so that solid stool can be produced and wastes be eliminated from the body. The absorbed water is returned to the body and reutilized.
Large intestine has a lining of mucosa which has tiny indentations called as crypts of Lieberkühn. They have many glands and goblets cells that are involved in absorption of fluids and secretion.
Answer: C
An amino acid has a central carbon atom surrounded by a hydrogen atom, a carboxyl group (-COOH) , an amino group(-NH2) and an alkyl group(-R). Hence if an a molecule has a singlt hydrogen atom which is bonded to a central carbon atom, an amino group and a carboxyl group both bonded to the same carbon atom, a R group which is also attached to the central carbon atom, the molecule is an amino acid(a monomer).
