Why is the Miller experiment important even though it did not create life nor did it duplicate the conditions of Earth’s early atmosphere?
Was there molecular oxygen in the earth's primitive atmosphere? How has that molecule become abundant?

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

Group of answer choices To demonstrate that oxygen can be produced by plants. To recreate the conditions of the Earth before life existed and produce the molecules necessary for life from primordial inorganic matter (water, methane, ammonia, and carbon dioxide). To build a case (though not necessarily prove) that life can originate from nonliving matter through natural means. To demonstrate that organic molecules like amino acids (building blocks of protein) and nucleotide bases (building blocks of DNA) do not necessarily originate only from living matter. To demonstrate that lightning may have been the essential energy source (early in Earth's evolution) in the production of molecules essential for life.arrow_forward
