8. which of the following pairs accurately connects a macromolecule to its monomer? a. carbohydrates–amino acids b. nucleic acids–nucleotides c. lipids–phosphate groups d. proteins–nitrogenous bases

The correct answer is option B. "Nucleic acids–nucleotides".

Explanation:

Nucleic acids are macromolecules used by living organisms to store its genetic information and translate it into active molecules such as proteins. The most common and abundant nucleic acids are DNA and RNA. Nucleic acids are comprised of nucleotides, therefore these two terms represent a macromolecule and its monomer.

nucleic acid molecules are incredibly complex, containing the code that guarantees the four different nucleotide units comprise dna, the nucleic acid of interest to the genealogist. and one of four nitrogen-containing molecules called nucleotides
