Afarmer planted legumes and cabbage in the same field that is devoid of fertilizers. the yield from this field is better than the cabbage planted in another field without legumes. why? . a. nitrogen-fixing present in the roots of legumes aid enrichment of nitrogen in the soil.. b. nitrogen-fixing bacteria present in the roots of legumes inhibit the growth of weeds or unwanted plants.. c. nitrogen-fixing bacteria present in the roots of legumes prevent bacterial growth that cause root disease.

the generally accepted parts of modern cell theory include: all known living things are made up of one or more cells. all living cells arise from pre-existing cells by division. the cell is the fundamental unit of structure and function in all living organisms.

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.
