Question

the model shows the chemical structure of a molecule. this molecule is a building block of which type of biomolecule? carbohydrate protein lipid nucleic acid

Explanation:

Carbohydrates have a general formula of (CH₂O)ₙ and are composed of carbon, hydrogen, and oxygen in a 1:2:1 ratio. Proteins are made up of amino - acid monomers with an amino group, a carboxyl group, a hydrogen atom, and a variable R - group attached to a central carbon. Nucleic acids are composed of nucleotides. The given molecule is a fatty acid, which is a building block of lipids. Fatty acids have a long hydrocarbon chain with a carboxyl group at one end.

Answer:

lipid
