ANSWER: WATER is not a biomolecule
EXPLANATION: There are four major biological molecules in nature namely: proteins, lipids, carbohydrates and nucleic acids. These four biomolecules are polymers, meaning that they are made up of monomeric units.
* Proteins are made up of monomers called amino acids.
* Lipids are made up of monomers called fatty acids.
* Carbohydrates are made up of monomers called monosaccharides
* Nucleic acids are made up of monomers called nucleotides.
Based on the above explanation, it shows that WATER is not one of the four biomolecules.
