The shape of a protein molecule is determined completely by

Its primary structure.

Explanation:

Proteins is polymers of the alpha amino acids that are linked together through the peptide bond. Proteins acts as the main building block of the body.

Proteins works effectively at its 3D shape. The shape of the protein is determined by the primary structure of the protein. The primary structure includes the sequence of the amino acids that determines the shape, structure and function of protein.

Thus, the answer is primary structure.

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.
