According to Oparin, which one of the following was not present in the primitive atmosphere of the earth?
1 Methane
2 Oxygen
3 Hydrogen
4 Water vapour
Explanation:
The first scientific explanation of origin of life was put forward by A.I. Oparin in 1923. J.B.S. Haldane (1928), also made similar observation regarding the origin of life. According to them primitive atmosphere was reducing atmosphere because hydrogen atoms (most numerous and most reactive) combined with all available oxygen atoms to form water and leaving no free oxygen. Therefore oxygen was not present in the primitive atmosphere of the earth.

In 1953 S. L. Miller created primitive earth condition in the laboratory and gave experimental evidence for origin of first form of life from pre-existing non-living organic molecules. The primitive earth conditions created include
1 Low temperature, volcanic storms, atmosphere rich in oxygen
3 High temperature, volcanic storms, non- reducing atmosphere
4 High temperature, volcanic storms, reducing atmosphere containing \(\mathrm{CH}_{4}\), \(\mathrm{NH}_{3}\) etc.
Explanation:
The conditions on earth were - high temperature, volcanic storms, reducing atmosphere containing \(\mathrm{CH}_{4}, \mathrm{NH}_{3}\), etc. In 1953, S.L. Miller, an American scientist created similar conditions in a laboratory scale. He created electric discharge in a closed flask containing \(\mathrm{CH}_{4}, \mathrm{H}_{2}, \mathrm{NH}_{3}\) and water vapour at 8000C.
