Excess carbon dioxide in the atmosphere is absorbed by in the process of carbon dioxide exchange. 1) soil 2) animals 3) oceans 4) plants

The correct answer is 4. Plants.

Plants use carbon dioxide for the photosynthesis process where they use carbon dioxide to form energy rich molecules and release oxygen to the atmosphere. The carbon is present in atmosphere as carbon dioxide in higher concentration and methane in lower concentration. Carbon dioxide is removed by several processes such as by the formation of carbonic acid when the surface ocean water cool down and absorb more carbon dioxide near the poles, through conversion of the reduced carbon to carbonates or organic tissues like shells and by photosynthesis of plants which is an exchange process where plants absorb carbon dioxide and in turn release oxygen.

c is the correct answer hope this !

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.
