Question

what are nondisjunction disorders?
what is hydrolysis/dehydration?

Answer 1

Dehydration - removal of water, in the chemical sense, it's the removal of H molecule. We can achieve this by Hydrolysis - "breaking of the "hydrogen bond" between the Hydrogen molecule and 2 molecules of Oxygen. Synthesis - is the opposite, it involves "building" instead of breaking.
for example Protein synthesis: involves building Proteins from it's basic units called amino acids. So, leucine + valine (Amino acids) = PROTEIN
