True

Explanation:

The air behind a cold front is cold and dry. This is true because the cold front has a cooler mass of air which is usually cold and dry and it replaces at ground level a warmer mass of air.

This cycle continues and results in evaporation and precipitation and helps in balancing the atmosphere.

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

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.
