Answer:
The correct answer is - kidney.
Explanation:
Osmoregulation is the process that bilogical system perform for the maintain osmotic balance in the blood plasma. There is a regular intake of electrolytes, water in the biological system from various proces.
The kidneys assists in the exported excessive electrolytes and water which is excreted to help in the maiantaining blood plasma on istonic level and prevent i from hypertonic or hypotonic condition that could lead to explosde of the cells. It return the amount of water from the transported amount of electrolyte and water so it can maintain the osmotic pressure in the cell.

The principal function of thyroxine is to stimulate the consumption of oxygen and thus the metabolism of all cells and tissues.
Thyroxine is termed T4. It travels through the blood to the target cells and becomes converted to triiodothyronine or T3.
T3 is the active form of thyroxine. T3 enters the target cell's nucleus binding to genes responsible or involved in the metabolism of sugar in the body. T3 stimulates these genes and in so doing metabolism (conversion of oxygen and calories to energy) is carried out by the cell, which also results in generation of body heat.
