Answer:
This description needs a unit describing the system of measurement.
The answer is Cl- or A. Hope it helps
Starch is easily digested by humans due to the presence of enzymes breaking its α-glucose bonds, while humans lack the enzymes to break the β-glucose bonds in cellulose, rendering it indigestible but essential as dietary fiber.
Starch and cellulose are both polysaccharides produced by plants. Their structural differences, however, determine how they can be digested by animals. Starch is made up of α-glucose molecules, which are joined together by 1-4 and 1-6 glycosidic bonds, forming a helical structure. The human digestive system has enzymes like amylase that can break these bonds, enabling the digestion of starch.

Answer:
The net ionic equation for the reaction of solid iron with aqueous copper sulfate:
Explanation:
Solid iron = Fe
Copper sulfate =
In an aqueous solution of copper sulfate we have copper (II) ions and sulfate ions.
In an aqueous solution of ferrous sulfate we have ion (II) ions and sulfate ions.
Cancelling out the common ions from both sides, we get the net ionic equation:
