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).
A positive feedback is a process in which an initial change will bring about an additional change in the same direction.An example of a simple positive feedback in everyday life is the growth of an interest-earning savings account.As interest is accrued the principal will begin to grow (assuming money is not withdrawn). As the principal grows, even more interest will be accrued, quickening the rate of principal growth.n example of a simple positive feedback in everyday life is the growth of an interest-earning savings account.
