Pollination.....................
A salt or ester of phosphoric acid, containing PO43− or a related anion or a group such as —OPO(OH)2.
Answer:
The correct answer will be option a and b.
Explanation:
The food is digested and absorbed in the small intestine, a long folded tube which lengths about 20 ft or 6m.
The small intestine increases the surface area for food absorption as they have circular folding as well as the finger-like projections called villi and microvilli in the lumen of the intestine. These villi help in absorption of the nutrients from the intestine.
Thus, option a and b are the correct options.
