Question

How could the Urey-Miller experiment be changed to accurately reflect our knowledge of the conditions of early Earth? Add carbohydrate molecules to the water Add bacteria to the amino acids Add oxygen to the mix of gases Add ultraviolet radiation to the electric current

Answer 1

I would say ultraviolet radiation b/c the atmosphere of early earth was much "thinner" then it is today letting much more U/V radiation come though

Answer 2

Answer:

The correct answer will be option-add ultraviolet radiation to the electric current.

Explanation:

The Urey and Miller performed the experiments to study the evolution of life on earth. These experiments were performed in-vitro in controlled conditions with the same conditions that existed on the earth during the time life involved. The atmosphere of the earth at that time was unstable with gases like CO, H₂S, SO₂ and N₂.

The stratification of the atmosphere lacked the ozone layer which protects the earth from the harmful UV radiation. This was demonstrated in the experiments as the ultraviolet radiation was added to the electric current.

Thus, the selected option is the correct answer.
