Document Summary

Properties of life: organized cells, heritable information (for reproduction, show growth, respond to stimuli, harness/utilize energy, exhibit homeostasis, adapt to environmental change. Cell theory: all cells are derived from other cells, all organisms are made of one or more cells, cells are the basic unit of life. All organisms, past or present, trace their ancestry back to one common ancestor. Biological evolution through natural selection because of genetic errors during replication environments and to adapt to changing ones. How life formed: abiotic synthesis, polymerization, package molecules into protobionts to separate internal chemistry, system of storing information and guide synthesis. Theories of abiotic synthesis: primordial soup: there was water vapor, h- 2o, co2, nh3, and ch4 but no o2. It was formed because environment was highly reducing (more reactive as chemicals try to bond) and eventually made o2: deep sea vents: really hot environment of.
