please help with this assignment. this is animal nutrition. please explain why you put the answer you did and if you don't know the answer please don't guess. if you have a hunch, please state that.
thanks in advance and I'll be sure to give a thumbs up.

Answer 1

22) Amylopectin

Amylose and Amylopectin are polysaccharides that can be found in the starch granules.The content of Amylopectin in starch is about 80% and the rest 20% is amylose.So Amylopectin is found in greater quantity in plants.

25) Simple lipids.

Fats and oils are come under the classification simple lipids.Simple lipids mainly consists of some non polar compounds which are mostly insoluble in water but get soluble in some non polar organic solvents like benzene, chloroform etc.

26) Hydrophilic

It is because the carboxyl end in fatty acid is actually a polar end.So it associates with water easily.Hence that end is Hydrophilic.
