Homeostasis and Immunity

4. The process of moving molecules across a cellular membrane through the use of cellular energy.
5. the measure of the amount of a sub-component in a solution
6. a substance produced by a living organism which acts as a catalyst to bring about a specific biochemical reaction
7. the chemical processes that occur within a living organism in order to maintain life.
8. he ability of an organism to resist a particular infection or toxin by the action of specific antibodies or sensitized white blood cells.
9. the net movement of molecules from an area where they are at a higher concentration to areas where they are at a lower concentration
10. the tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes
11. the spontaneous net movement or diffusion of solvent molecules through a selectively permeable membrane from a region of high water potential to a region of low water potential, in the direction that tends to equalize the solute concentrations on the two sides
12. a substance used to stimulate the production of antibodies and provide immunity against one or several diseases, prepared from the causative agent of a disease, its products, or a synthetic substitute, treated to act as an antigen without inducing the disease
13. a toxin or other foreign substance which induces an immune response in the body, especially the production of antibodies

1. unplanned sequence or action and nearly instantaneous movement in response to a stimulus
2. a mechanism by which mammals maintain body temperature with tightly controlled self-regulation independent of external temperatures.
3. responses to stimuli that are consciously controlled or co-ordinated by the brain
4. a blood protein produced in response to and counteracting a specific antigen.
