Question

Which is true according to Oparin and Haldane?

A) The formation of amino acids was probably complete within one million years.
B) The first organic molecules were formed in the sea, from the gases in the atmosphere.
C) The early atmosphere contained methane, carbon dioxide, and oxygen
D) Organic molecules eventually merged from several places on Earth.

Answer 1

Answer:

The first organic molecules were formed in the sea, from the gases in the atmosphere.

Answer 2

(B)

Haldane proposed that the primordial sea served as a vast chemical laboratory powered by solar energy. The atmosphere was oxygen free, and the combination of carbon dioxide, ammonia and ultraviolet radiation gave rise to a host of organic compounds. The sea became a 'hot dilute soup' containing large populations of organic monomers and polymers. Haldane envisaged that groups of monomers and polymers acquired lipid membranes, and that further developments eventually led to the first living cells.
