Homeostasis Assignment (15 pts.) 1. Define homeostasis. The ability of an organism to maintain constant body temperature, fluid balance, and chemistry in a changing exterior environment. 2. Give an example of dynamic equilibrium. a) Homeostasis b) Example of dynamic equilibrium is NO2(g) + CO(g) ⇌ NO(g) + CO2(g) (again, if the two rates are equal). Nitrogen dioxide (NO2) reacts with carbon monoxide (CO) to form nitrogen oxide (NO) and carbon dioxide (CO2), and, in the reverse reaction, nitrogen oxide and carbon dioxide react to form nitrogen dioxide and carbon monoxide. 3. At what levels of our biological organization is homeostasis happening? Homeostasis is happening at all levels of biological organization – from cells to tissues to organs to organ systems to organisms to the environment of regions of Earth and to the entire Earth itself. 4. Give an example of an imbalance in human body homeostasis that can have severe repercussions or effect.
