Document Summary

-atp ( from cellular respiration) source of energy. -light, inorganic compounds (h2, h2s), organic compounds energy transformation of organisms. -make copies of themselves asexual no gametes sexual--gametes: maintain homeostasis. -chemical evolution on earth (hypothesis supported by experimental results: mimic earth"s early atmosphere and lightening in lab (gas mixture with zap of electricity) -creates monomers (amino acids, nucleotides, sugars: condensation to mimic clay shores, hot springs. -form polymers (proteins, carbohydrates, rna/dna, lipids: rna appears before dna, lipids naturally form bilayer spheres.
