Document Summary
The upper temperature for life is 130*c, cell and body temperatures can range from -2*c-130*c and pressure ranges from 1atm-1100atm, the average depth of the ocean is 2*-4*c body temperatures and approximately -380atm with no sunlight @ 3. 8km: organisms confront a variety of problems due to their environment, antarctic fishes live at -2*c and are ectotherms meaning their body temperature is determined by their environments temperature. Fish accumulate antifreeze molecule (proteins to prevent freezing to death) Thermophiles- bacteria exist at temperatures up to 130* and grow up till 121*. Sharks- live with molar used in their tissues to match the osmotic strength of the sea water. Elements- pure substances which cannot be broken down to simpler substances. There are 92 naturally occurring elements and 103 total. Atom- the smallest unit an element can be divided into and retain its identity. Neutrons (neutral charge) and protons (+1 charge) make up the nucleus. Electron has a-1 charge and essentially no mass.
