Theory of abiogenesis was conclusively disproved by
1 Conducting swan neck experiment by Richter
2 Conducting broth experiment by Spallanzani
3 Conducting swan neck experiment by Pasteur
4 conducting maggot experiment by Redi
Explanation:
Louis pasteur is credited with conclusively disproving the theory of spontaneous generation with his famous swan-neck flask experiment. He subsequently proposed that " life only comes from life"

Primitive earth had
1 Reducing atmosphere (without free oxygen)
2 Oxidizing atmosphere (free oxygen)
3 Both (a) and (b)
4 None of the above
Explanation:
Primitive Earth had a reducing atmosphere, primarily composed of gases like methane, ammonia, water vapour and \(\mathrm{CO}_{2}\). This atmosphere lacked free oxygen.
