a. rate of expansion.

Explanation:

The various theories of the final destination of the universe depend on the current current of the universe, known as the rate of expansion.

We then use the term expansion rate which is related to the measure of how much the total space of the universe has increased over time. It is also necessary to clarify that relativity only restricts the speed at which bodies move through space, but it does not in any way restrict the rate at which space changes in size. One of the effects of the expansion of the Universe is to make us see the galaxies around us moving away from us. In addition, this distance speed is proportional to the distance between us and the observed astronomical object. This means that an object that is more distant moves away from us faster than another that is closer

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.
