Solved in 2 steps
- how conditions and resources influence organisms.Describing the features of cells that suggest that all living organisms are derived from a common ancestor.True or false: The "Miller Urey" experiment that found heating and cooling gases such as H20 and CH4 were able to produce small organic molecules. This proved that life originated on Earth through natural mechanisms.
- Scientist have determined that the early Earth had no free oxygen anywhere. Briefly explain what evidence in the rock layers that scientists found to prove when the early conditions on earth had free oxygen in the atmosphere.An abundance of___________ in Earths early atmosphere would have prevented the spontaneous assembly of organic compounds on early Earth. a. hydrogen b. methane c. oxygen d. nitrogenIn Stanley Miller’s experiment to recreate the early Earth conditions that gave rise to life, describe which part of the experimental instruments mimicked the ocean, the atmosphere, rain, and lightning.
