Question

In the 1950s, Stanley Miller and Harold Urey designed experiments that tested Alexander Oparin's and J.B.S. Haldane's hypothesis that conditions on the primitive Earth favored chemical reactions that synthesized more complex organic compounds from simpler organic precursors. Miller and Urey used an apparatus that recreated the conditions of what a primitive Earth was thought to consist of at the time. Methane, hydrogen, ammonia, and steam were all included to recreate conditions similar to that of a primitive Earth. Their goal was to create complex organic molecules from the simple organic molecules that were believed to be part of primitive Earth's makeup. The Miller-Urey experiment was run for a week and the samples collected were analyzed. Analysis showed that some of the carbon in the apparatus was converted to amino acids molecules. In later experiments, similar to Miller and Urey's, it has been shown that it is possible to form all 20 amino acids commonly found in organisms. Along with nucleic acids, other molecules were detected in samples. Some of these were sugars, lipids, adenine, and even ATP in certain conditions.

Based on the information in The Miller-Urey Experiment reading passage above, which of the following statements is most accurate?

Answer 1

The Miller-Urey experiment showed that life's organic building blocks could form under conditions simulating early Earth, adding evidence to the hypothesis of abiogenesis.

Step-by-step explanation:

Based on the information provided, the most accurate statement about the Miller-Urey experiment is that it demonstrated the plausibility of the hypothesis that life's basic building blocks could have formed on early Earth under the conditions that were believed to exist at the time. In their experiment, Stanley Miller and Harold Urey simulated early Earth conditions by using a mixture of water (H₂O), methane (CH₄), hydrogen (H₂), and ammonia (NH₃), and exposed it to electrical sparks to mimic lightning. Their findings included the spontaneous formation of amino acids, which are essential for life, as well as the production of other organic molecules such as nucleic acids, sugars, and lipids under certain conditions. The experiment was groundbreaking in the understanding of abiogenesis, the natural process by which life could have arisen from non-living matter on prebiotic Earth.
