Most macromolecules are polymers of simple molecules (monomers). There is not a great variety of simple molecules, but their structure determines the macromolecule. For example, proteins are macromolecules synthesized from amino acids. There are only 20 amino acids and a great number of proteins made of different combinations of those 20 amino acids.
Answer:
C
Explanation:
The rough endoplasmic reticulum contains ribosomes that synthesize proteins then transports them.
The genes are from the nuclei of the egg (from the female) and the sperm (from the male) the different traits are joined to create the particular genes.
(I might be right.)
Answer:
Cell
Explanation:
A cell is the smallest unit of a living thing.
Prokaryotic cells also have loose/free/a ring of DNA (not confined to a nucleus) and they can also sometimes have a capsule (slimy outer layer). Also they have slightly smaller ribosomes- 70s instead of 80s.
