Biological macromolecules are organized into four main categories. What type of macromolecule contains phosphorus as part of a phosphate group? 1.) lipids
2.) proteins
3.) nucleic acid
4.) carbohydrates

3.) nucleic acid

Explanation:

Biological macromolecules can be defined as a very large molecule (structure) that comprises of covalently bonded organic atoms and smaller molecular structures (monomers).

Biological macromolecules are organized into four main categories and these includes;

I. Lipids: these categories of biological molecules is mainly made up of fats and it is responsible for providing the body with long-term energy.

II. Carbohydrates: it is contained in energy-giving foods and it aids the functioning of the muscles, nervous system and other organs found in the body.

III. Proteins: it contains amino acids and it is responsible for maintaining the functioning of the body system.

IV. Nucleic acid: it comprises of deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) which are the genetic codes (blueprints) for living organisms.

Hence, the type of macromolecule that contains phosphorus as part of a phosphate group (sugar 2-deoxyribose) is nucleic acid.

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms
