What biological macromolecule is made up of monomers like the one shown below? A molecule with an amino group, carboxylic acid, hydrogen atom, and R group bonded to a central carbon atom.

Lipid
Nucleic acid
Protein
Carbohydrate

Protein.

Explanation:

Proteins consist of an R group/carboxylic acid  unlike any of these. Look at this image- hope it helps

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

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

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.
