Considering the various theories, the energy used in forming organic molecules in the primitive atmosphere could have come from all EXCEPT Select one: a. lightning. b. ultraviolet radiation. c. heat from volcanoes. d. electric spark. e. sound.

e. sound.

Explanation:

Such type of atmosphere in which oxygen was not present or was present in little amount is known as the primitive atmosphere and such type of atmosphere was present in the initial stage of the earth formation. During this period, water vapor, nitrogen, hydrogen and carbon dioxide gases were present. These gases interact with the help of energy that comes from many sources such as lightning, ultraviolet radiation, electric spark and some other. When these inorganic molecules react in the then the formation of organic compounds takes place that becomes the basis of the organization of the life on the earth and called an organic evolution of life.
