Okay i don't know how to answer this question:
Explain how its possible to have so many different types of biological molecules from a limited amount of monomers.
I've put this, but don't think its correct:
It’s possible to have so many different types of biological molecules from a limited amount of monomers as monomers can form long chains to form a polymer. For instance, fatty acids (monomer/monosaccaride) can form a Polymer to produce Triglycerides (Carbohydrate). Also, monomers can break and form bonds via condensation reaction and hydrolysis.
(as Glucose is a type of Carbohydrate) as monomers can form long chains
