John is a 26-year-old man who begins to notice a progressive enlargement of feet, hands, cranium, nose, and lower jaw bone. his doctor recommends irradiation of the pituitary gland. what is the most likely diagnosis, and what caused this condition?

Acromegaly is a condition, in which the body of the fully grown adults, mostly the middle aged ones continues to grow. In this condition, the size of the feet, bones, hands, cranium and the body increase abnormally.  

This condition is mainly caused by the overproduction of the growth hormone from the pituitary gland. This overproduction of growth hormone can be due to the presence of the non cancerous tumor in pituitary. That is why, his doctor suggests irradiation of pituitary.  

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.

emerging idea only occurs as a raw idea that could appear out of nowhere. meanwhile, to reach scientific consensus , that idea must be structured and tested over and over again through various experiments. the scientific consensus transforms the raw idea into idea that is more reliable through the process of scientific elimination.
