Will geographical isolation be a major factor in the speciation of an organism that reproduces asexually? why or why not?

Geographical isolation would have more of an impact on speciation if it was an organism that reproduced sexually. If a positive mutation were to occur in an asexually reproducing organism that allowed it to survive better, evolution would be very sudden. There are many factors that can impact whether an organism is more fit and I do believe geographical differences can influence this. If the climate of an area suddenly drops but one organism can survive, they will pass their genes on and the rest will not.

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
