Group the following carbohydrates based on their characteristics and examples: monosaccharide, disaccharide, polysaccharide.
monosaccharide: formed from two monosaccharide units, table sugar
disaccharide: single sugar molecule, glucose
polysaccharide: three or more sugar molecules, starch
monosaccharide: single sugar molecule, glucose
disaccharide: formed from two monosaccharide units, table sugar
polysaccharide: three or more sugar molecules, starch
monosaccharide: single sugar molecule, glucose
disaccharide: three or more sugar molecules, starch
polysaccharide: formed from two monosaccharide units, table sugar

Explanation:

Carbohydrates are defined as the compounds that consists of carbon, hydrogen and oxygen atom which are neutral in nature.

Carbohydrates are of three types. That is, monosaccharide, disaccharide, and polysaccharride.

Monosaccharide : Carbohydrates which contain only one or single monomer unit are known as monosaccharide. For example, glucose.

Disaccharide : Carbohydrates which contain two monosaccharide units or two monomer units are called disaccharides. For example, sucrose which is a sugar is a disaccharide.

Polysaccharide : Carbohydrates which contain more than two monomer units is known as a polysaccharide. For example, starch, glycogen etc are polysaccharides.

Thus, we distinguish the given groups as follows.

well, that's easy; the answer's c, "it reduces contamination of the water and substrate of the estuary."
