(25 points) a carbohydrate molecule is; a. a macromolecule made of amino acids that provides structure for a cell and is not soluble in water b. made up of a chain of monosaccharides that transport genetic coding from one end of the cell to another c. made up of the monosaccharide glucose and serves as an energy reserve in plants and animals d. a chain of amino acids that can be used for protein synthesis, protection, and increasing reaction speeds

I legit just did this TODAY in biology class so I gotchu.

The correct answer will be option- C.

Explanation:

The carbohydrate molecule is one of the four macromolecules present in the living organism which performs several functions from storage to structural components.

The carbohydrate molecules are composed of structural units called monosaccharides which are usually glucose and fructose bonded with the glycosidic bond.  These monosaccharides form polysaccharides which can be stored in plants as starch and in animals as glycogen.

Thus, Option-C is the correct answer.

poor water quality affects most estuarine organisms, including commercially important fish and shellfish. the pollutants that have the greatest impact on the health of estuaries include toxic substances like chemicals and heavy metals, nutrient pollution (or eutrophication), and pathogens such as bacteria or viruses.

i'd say that the moon rock is about 2.2 billion years old.
