Answer 2

1.Osmoregulation

2.Thermoregulation

Step-by-step explanation:

1.Osmoregulation is the maintenance of constant amount of water in the body of an organism.The kidney is responsible for this phenomenon as in it has a nephron in which at a particular part of the nephron,i.e the conducting tube which sites a hormone called the anti diuretic hormone which makes the walls of the conducting tube permeable to allow the movement of water from the urea back into the body before it is transferred into the bladder for to be released into the external environment.

2.Thermoregulation involves the maintenance of heat in the body of an organism.The skin is responsible for this process.It has hairs which lie on the surface of the skin to loose heat to the external environment during the hot days and also stands on the surface of the skin which trap a film of air on the skin surface to prevent heat loss in the cold days.
