- Organisms that evolved the ability to use photosynthesis radically changed Earth by producing ___________. Group of answer choices hydrogen oxygen sugar celluloseThe Miller-Urey experiment simulated compounds present in the atmosphere of early Earth, lightning, and the evaporation and condensation of atmospheric water. What other information about the conditions on Earth during this time period would you want to know to improve the experimentSuppose that a prokaryotic organism that contains both chlorophyll a and chlorophyll b has been discovered. Comment on the evolutionary implications of such a discovery.
