fatty acids
nucleic acid
dna
rna
nucleotides
monosaccharides

polymers
fructose
lipid
amino acids
protein
glucose
starch

match the molecule with the elements that make it up

Explanation:

First, classify molecules into monomers (building blocks) and polymers (large molecules made of monomers):

1. Monomers: These are the small, repeating subunits that form polymers.

• Fatty acids are subunits for lipids; nucleotides are subunits for nucleic acids; monosaccharides (fructose, glucose) are subunits for carbohydrates; amino acids are subunits for proteins.

1. Polymers: These are large molecules formed by linking monomers.

• Lipids are formed from fatty acids; proteins from amino acids; starch (a carbohydrate) from monosaccharides; nucleic acids (DNA, RNA) from nucleotides.

Then, match each molecule to its constituent elements (standard biological composition):

• Carbohydrates (fructose, glucose, starch): Composed of carbon (C), hydrogen (H), oxygen (O)
• Lipids (fatty acids, lipid): Composed of carbon (C), hydrogen (H), oxygen (O) (some have phosphorus)
• Proteins (amino acids, protein): Composed of carbon (C), hydrogen (H), oxygen (O), nitrogen (N) (some have sulfur)
• Nucleic Acids (nucleotides, nucleic acid, DNA, RNA): Composed of carbon (C), hydrogen (H), oxygen (O), nitrogen (N), phosphorus (P)

Answer:
