This mutation has introduce a new allele into the population that increases genetic variation and may be passed on to the next generation.
The answer is D. Extracellular,
the main ions involve in osmoregulation in a cell are sodium and chloride. Intra-and extracellular distribution of K+ is
influenced, for example, by Na+/K+-ATPase
