Henrietta norman complains of dry mouth. The medical term for this condition is termed as xerostomia

Explanation:

Xerostomia is not a disease but a salivary condition which is arises due to intake of anti-biotics or sever medication for other diseases. It may sometimes be dependent on the activity of the salivary glands or may not involve the function of the salivary glands. The salivary secretion is impaired in this case, the saliva is an important component that is required for the digestion process.

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.
