Question

Which of the following were present in prebiotic soup?
A. Zn, Fe, Al
B. Proteins, nucleic acids, carbohydrates, lipids
C. Vitamins
D. None

Answer 1

Hint: The earth was formed billion years and then life on earth began later. Many theories and hypotheses were proposed by many scientists regarding the origin of the earth, one of these was the primordial soup hypothesis which was given by Haldane and Oparin.

Complete answer: The prebiotic soup was also called the primordial soup. It was the hypothetical set of conditions that were present on the earth around millions of years ago, which resulted in the combination of chemicals that formed amino acids and nucleotides which were proteins and nucleic acids. The nucleus was surrounded by the light elements which were the gases of hydrogen and the presence of water vapour that reacted with hydrogen and formed hydrocarbons. These hydrocarbons were the first organic molecule which was further combined with the oxygen that resulted in carbohydrates and lipids. The prebiotic soup which was coined by Haldane and Oparin. The prebiotic soup was rich in methane and ammonia. Further, Stanley Miller and Harold Urey conducted an experiment to test the Oparin and Haldane theory which resulted in organic molecules being spontaneously produced under reducing conditions which were thought to be the early earth.
Hence, the correct answer is option B.

Note: Earth formed around 4.54 billion years ago, approximately one-third the age of the universe, by accretion from the solar nebula. The earth was in the molten state initially because of frequent collisions with other bodies which led to extreme volcanism.
