Explanation:
Homeostasis is the regulation of internal body conditions such as temperature, sugar levels in blood, salt content etc. Without it many functions would become non-functional. If you take temperature for example without the control of our internal body temperature many metabolic reactions (enzyme-controlled reactions) would stop/ slow down. If the temp gets too high the enzymes denature and you wouldn't get an enzyme-substrate complexes forming. If the temp is too low the enzymes have a low kinetic energy and so don't collide with the substrate as much as at normal body temp. pH has similar affect but a change in pH will always denature enzymes.
The US Environmental Protection Agency issues a daily report for pollution levels called the air quality index. It is a number used by government agencies to tell the public how polluted the air currently. It is also used to forecast the air quality. A high number is likely to have adverse health effects to the public.
