- Scientists Stanley Miller and Harold Urey set up an experiment modeling the environmental conditions thought to exist during the early stages of Earth's formation. The setup of Miller and Urey's experiment is shown below. Which conclusion about the origin of life could be drawn from the potential results of this experiment? Life assembled from chemical building blocks. Life began when water vapor became electrified. Life evolved from the DNA of simple unicellular organisms. Life began when salt water caused a mutation in an ancient virus.arrow_forwardScientists think that terrestrial life probably originated in Earth's oceans becauseChoose one: A. energy was available there. B. all of the chemical pieces were there. C. All of the possible answers are correct. D. the earliest evidence for life on Earth comes in ocean-dwelling forms.arrow_forwardIn the 1950s, scientists Miller and Urey conducted a classic experiment in which water, methane, ammonia, and hydrogen were sealed in a flask containing a pair of electrodes. An electric spark was fired between the electrodes, and after a week's time, they found that amino acids were present in the flask. Which of the following best explains the significance of this experiment in explaining the origin of life on Earth? A. It showed that any raw materials could produce the compounds necessary for life to exist on early Earth. B. It showed that life must have started somewhere else since organic compounds only come from living thin C. It showed how biological molecules can be formed from the very simple molecules that were available on early Earth. D. It showed how lightning can cause organic matter to decompose into amino acids, which were the first molecules on early Earth.arrow_forward
