Giving brainliest!! The monomers, or small units, used in the synthesis of DNA molecules are called

disaccharides
amino acids
nitrogenous bases
nucleotides

the answer is nucleotides

D. nucleotides

Explanation:

The monomers of DNA are called nucleotides. Nucleotides have three components: a base, a sugar (deoxyribose) and a phosphate residue. The four bases are adenine (A), cytosine (C), guanine (G) and thymine (T). The sugar and phosphate create a backbone down either side of the double helix.

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a

the answer is:

carbon dioxide
