was rich in oxygen.

Detailed explanation-1: -The three-dimensional structure of a protein is determined primarily by: E) the sequence of amino acids in the protein. According to Oparin’s theory for the origin of life, the prebiotic atmosphere: D) had an abundance of methane, ammonia, and water.
Detailed explanation-2: -Haldane coined the term ‘prebiotic soup’ or ‘prebiotic atmosphere’ that consisted of an abundance of methane, ammonia, and water. This term became a powerful symbol of the Oparin-Haldane view of the origin of life.
Detailed explanation-3: -The Oparin-Haldane hypothesis suggests that life arose gradually from inorganic molecules, with “building blocks” like amino acids forming first and then combining to make complex polymers.
Detailed explanation-4: -Oparin and Haldane suggested that the early earth’s environment contained the correct conditions and precursors to create the basic building blocks of life. They reasoned that this cannot happen in the modern world because the present atmosphere is rich in oxygen produced by photosynthetic life.
