All living things are made up of four classes of biological macromolecules: carbohydrates, lipids, proteins, and nucleic acids.
macromolecules are large molecules composed of thousands of covalently connected atoms, also called polymers. a polymer is a long molecule
consisting of many similar building blocks; the small building block molecules are called monomers.
all cells have thousands of different macromolecules, that vary among cells of an organism, vary more within a species, and vary even more between
species. a huge variety of polymers can be built from a small set of monomers. what statement are true about the biology macromolecules
