The classification system for organisms has changed from seven to eight. this happened because
a. scientific consensus changed as scientists learned more about organisms.
b. scientist did not test the seven level system often enough to lead consensus.
c. the eight level system of classification is an emerging idea that needs more testing.
d. the seven level system of classification was not supported by scientist.

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.

i dont know it at allnow im just getting points at this pint
