Which term describes the maintenance of a steady internal state in the body?
e-lub [12.9K]
In other words, the term homeostasis is being used to describe the body’s maintenance during resting conditions whereas the term steady state refers to the body’s maintenance<span> during exercise; exercise is a stressor which disrupts homeostasis, also called homeostatic disturbance (e.g. an increase in temperature).







</span>Homeostasis is the maintenance of a constant internal environment (the immediate surroundings of cells) in response to changes in:

the changing conditions of the external environment.
the changing conditions of the internal environment.


Homeostasis is a self adjusting mechanism involving feedback where the response to a stimulus alters the internal conditions and may itself become a new stimulus.

<span> Homeostasis works to maintain the organism's internal environment within tolerance limits - the narrow range of conditions where cellular processes are able to function at a level consistent with the continuation of life. </span>

The electrical energy used by the radio is converted into sound energy. Sound is another form of kinetic energy--it's air in motion. space heater- Space heaters work by utilizing convection or radiant heating. Radiant heaters emit infrared radiation into the room that directly heats objects and people who are close to them. One way to generate electricity is to burn solid waste, like the material found in landfills. ... That thermal energy is transformed into electrical energy, usually by turning a turbine. Another energy resource that comes from our garbage is the methane gas that is produced as the waste decays.  A television set is another device that operates by the transformation of energy. An electrical beam from the back of the television tube strikes a thin layer of chemicals on the television screen, causing them to glow. In this case, electrical energy is converted into light.
