Document Summary
Sensitivity (respond to stimuli: cellular organization, ordered complexity, growth, development, & reproduction, energy utilization, homeostasis, evolutionary adaptation. [it was originally molten but as it cooled water formed: the oldest rocks was 4. 4 billion years ago, the first forms of life discovered as fossils is bacteria [blue-green bacteria found in. Spallanzani"s experiment disproved the theory by comparing it in a closed system and open system. Pasteur"s experiment: did the same thing as spallanzani"s but allowed air in but not microbes in: primary abiogenesis: Life came from inorganic chemicals - oparin & haldane proposed: Chemical evolution: 1) inorganic chemicals 2) organic chemicals 3) interacting. Biological evolution: 4) reproducing molecules 5) cells 6) multicellular organisms: millier & urey"s experiment in 1953 and 1959. [this was a closed system: he tested the gunk and found amino acid [organic molecules] formed form the inorganic solution. Simple organic molecules have been detected in space: it"s easy to produce organic.
