The classical laboratory experiments performed by Urey and Miller in order to explore the necessary conditions for the production of organic molecules (the building blocks of living things)in the solar system involved the passing of electrical discharges through what mixture of gases?

Question

Quizplus · Accepted Answer

The Urey and Miller experiment involved passing electrical discharges through a mixture of ammonia, methane, water vapor, and hydrogen. This was done to simulate the conditions of the early Earth's atmosphere and test whether organic molecules could be formed under these conditions. The experiment was successful in producing several amino acids, which are the building blocks of proteins, leading to the hypothesis that the early Earth's atmosphere had the necessary conditions for the formation of life.
