You are analyzing an unknown substance. You determine that it is made up of sugars, phosphates, and nitrogenous bases. What type of molecule is this substance most likely to be

a nucleic acid

Explanation:

A nucleic acid is a biomolecule composed of subunits called nucleotides. Nucleotides are made of three types of molecules: a 5-carbon sugar molecule, a phosphate group, and a nitrogenous base. There are two types of nucleic acids: ribonucleic acid (RNA) and deoxyribonucleic acid (DNA) and they are involved in the genetic information transfer in living organisms.

this age may represent the age of the earth's accretion, of core formation, or of the material from which the earth formed. this dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.
