Question

The Stanley Miller apparatus demonstrated that organic molecules could assemble spontaneously in an environment lacking free oxygen and containing water, methane, and ammonia in the presence of an abundant energy source, such as an electric discharge. The research was considered supportive of the organic soup hypothesis, which states that the primitive atmosphere provided inorganic precursors from which organic molecules could have been synthesized in the presence of an energy source. Based on subsequent research, the primordial atmosphere was determined to contain less methane and more carbon dioxide. The new data about the composition of the early atmosphere had which of the following effects on origin-of-life hypotheses?
a) Miller's work was discarded as not relevant to an origin- of-life hypothesisb) Miller's work was used to refute the new hypothesis about the composition of the atmospherec) The organic soup hypothesis was abandoned as no longer being supportabled) A new organic soup hypothesis was proposed to account for the new data about the atmosphere

Answer 1

Answer:

Option (D).

Explanation:

Miller and Urey perform the experiment that was proposed by Haldane on the evolution of life on earth. The earth's earlier temperature is reducing and thunder, lightning is common in that environment.

The origin of hypothesis on the basis of Miller and Urey experiment expleins that the life has been originated from the organic soup. The organic soup hypothesis can be used to propose the new data about the atmosphere. The primordial atmosphere contains more carbon dioxide.

Thus, the correct answer is option (D).
