Is a form of pollution in which atmospheric moisture becomes chemically changed from exposure to certain toxic gasses. a. acid rain b. basic rain c. point source pollution d. non-point source pollution

A. Acid rain

Explanation:

The acid rain is a rain that is generated as a result of pollution. This rain forms when the moisture present in the atmosphere reacts with the sulphur dioxide toxic gas present as pollutant in the atmosphere. This will lead to the formation of sulphuric acid which affects the living beings and the man-made structures like buildings.

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.
