The Effect of Temperature on the Activity of Rennin in Milk

Homeostasis is a natural process in the body that regulates the body's internal environment to keep body systems functioning well. For the body cells to survive and function properly, the composition and temperature of the fluids around the cells must remain much the same. An organism is said to be in homeostasis when the internal environment contains the optimal concentration of gasses, nutrients ions and water, at the optimal temperature. Homeostasis is maintained mainly by a process called feedback, there are two types of feedback positive and negative. The negative form simply reduces a function (like heat production) if it exceeded body's need. Internal sensors monitor parameters' value (the amount of heat, temperature) and initialize a chain reaction that eventually reduces heat-producing metabolic reactions. Positive feedback systems are not used very often as they accelerate a function if a specific stimulus has been triggered (maybe a favorable situation has been detected).
