In the Oparin-Haldane experiment, the artificial atmosphere they created contained which of the following?I. Hydrogen gasII. Oxygen gasIII. Reducing gases
Correct answer: D. I and III
- A. I only
- B. II only
- C. I and II
- D. I and III
Explanation
Oparin and Haldane's artificial atmosphere contained hydrogen gas and other reducing gases. It did not contain oxygen gas, which characterises the current oxidising atmosphere. This is correct.

About Concept of Evolution
Evolution is the heritable change in populations over generations, driven by mutation, recombination, natural selection, genetic drift and reproductive isolation. Questions examine variation, adaptation, survival and reproduction, speciation, fossil and anatomical evidence, and the difference between individual acclimatization and evolutionary change in a population.
