The four major classes of biological macromolecules are carbohydrates, lipids, proteins, and nucleic acids.
Answer:
Prokaryotes.
Explanation:
Most of the Eukaryotes most likely to evolve from the Prokaryotes. Prokaryotes are basically unicellular organisms that lack internal membrane-bound structures. So, they do not carry nucleus and generally have a single chromosome. Most of them have a cell wall outside the plasma membrane, which is a thin layer of lipid that completely surrounds the cell. Prokaryotes reproduce by binary fission method.
Sex is important because its how we reproduce we create new life so that they can create new life and so on with out sex theres no life if that makes sense
