Based on the information provided, which of the following statements accurately describes the purpose and setup of Stanley Miller's classic experiment regarding the origin of life?

  • A: To prove that complex organisms could spontaneously generate from non-living matter by replicating modern atmospheric conditions.
  • B: To demonstrate the abiotic synthesis of organic compounds by simulating early Earth conditions, using gases like H2, CH4, NH3, and water vapor.
  • C: To show that life could originate from inorganic compounds by exposing them to high temperatures and oxygen-rich environments.
  • D: To analyze the chemical composition of meteorites and their role in delivering organic molecules to early Earth.

Explanation

Stanley Miller's experiment aimed to simulate the conditions of early Earth to demonstrate the abiotic nonliving synthesis of organic compounds. He used a closed system with a 'sea' flask heated water and an 'atmosphere' flask containing hydrogen gas H2 , methane CH4 , ammonia NH3 , and water vapor, with sparks to mimic lightning.
