Document Summary
Viruses: are not considered alive b/c w/o a hosts cell they die and are unable to make proteins. Utilization of energy, ability to make proteins and membranes all interact in metabolic processes. All components of the solar system formed at the same time, through gravitational condensation of matter in interstellar cloud (hydrogen) Heat from the sun allow temperature where water exists in a liquid state. All life forms made up of nucleic acids, proteins, lipids, carbs. Atmosphere had very little oxygen, with alot of water, hydrogen, carbon dioxide, ammonia, methane which helped make organic molecules. Enter lots of reactions w/ ea other products would be complex organic molecules. Today we have a oxidizing atmosphere there was no ozone layer back then which formed after the rise in oxygen levels this was recreated in the lab, and it worked. Organic molecules originated in vents located in the sea floors.
