In birds, placenta develops from the chorion and extends into the uterine lining.

In humans, placenta develops from the chorion and extends into the uterine lining.

In humans, the placenta (originating from the chorion) allows for the exchange of oxygen and metabolic wastes.

In birds, the placenta (originating from the chorion) allows for the exchange of oxygen and metabolic wastes.

In birds, the chorion is involved in gas exchange

In humans, the chorion is involved in gas exchange

In birds, the chorion combines with the allantois (an extra-embryonic membrane) rather than with the mother’s tissues

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.

your answer would be a, maximum exploitation of resources.

the answer is false.. have a great day; )
