Answer:
Maintenance of internal conditions within a limited range.
Step-by-step explanation:
Homeostasis refers to the ability of the body to maintain internal stability to compensate for environmental changes. Homeostasis maintains conditions inside an organism in an stable, relatively constant way. This state of equilibrium maintains the body functioning correctly.
Thus, the goal of homeostasis is the maintenance of internal conditions within a limited range in order to achieve equilibrium.
Note:
Homeostasis does not manipulate external conditions but internal ones, therefore the option of "manipulation of the external environment to meet the needs of the internal environment" is incorrect.
One of the functions of homeostasis is generation of body heat, however, it's not the only one (it also includes maintenance of levels of sugar and vitamins in the body, for example) so, the option " generation of body heat"
Homeostasis process makes the necessary changes in the systems in the body in order to maintain equilibrium when the environment changes, thus homeostasis is not about making no changes on the systems but to make the necessary changes adapting to the environment. Thus the option "status quo (no change) of all systems in the body" is incorrect.
