Answer:
Protein evolution is inescapably tied to changes and selection of DNA polymorphisms and mutations because protein sequences change in response to alterations in the DNA sequence.
Amino acid sequences and nucleic acid sequences do not mutate at the same rate.
The surviving species evolve more rapidly
Osmosis is the spontaneous net movement of solvent molecules through a semi-permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides.It may also be used to describe a physical process in which any solvent moves across a semipermeable membrane (permeable to the solvent, but not the solute) separating two solutions of different concentrations.Osmosis can be made to do work.
Osmotic pressure is defined as the external pressure required to be applied so that there is no net movement of solvent across the membrane.
