For example, if a 37-year-old Marine with 10 years of service desires to reenlist in the Marine Corps, his/her age will be 27 for enlistment purposes. Although the maximum age for enlistment is 35, any individual older than 28 is required to request an age waiver.
Homeostasis. The biological definition of homeostasis is âthe tendency of an organism or cell to regulate its internal environment and maintain equilibrium, usually by a system of feedback controls, so as to stabilize health and functioningâ.lmost all homeostatic control mechanisms are negative feedback mechanisms. These mechanisms change the variable back to its original state or âideal valueâ. A good example of a negative feedback mechanism is a home thermostat (heating system).
Homeostatic control. In the body of an animal conditions such as water concentration, temperature, and glucose concentration must be kept as constant as possible. Control systems that keep such conditions constant are examples of homeostasis; this is the maintenance of constant internal conditions in an organism.Negative feedback is an important type of control that is found in homeostasis.A negative feedback control system responds when conditions change from the ideal or set point and returns conditions to this set point. There is a continuous cycle of events in negative feedback.egative feedback is an important type of control that is found in homeostasis. A negative feedback control system responds when conditions change from the ideal or set point and returns conditions to this set point. There is a continuous cycle of events in negative feedback.
