Question

Scientists Stanley Miller and Harold Urey sealed water, methane, ammonia, and hydrogen in a flask, to simulate Earth’s early environment. They exposed the chemicals to electric charges to simulate lighting. What did the process produce?

A. nucleic acids

B. bacteria

C. viruses

D. amino acids

Answer 1

Amino acids

Step-by-step explanation:

Hope it helps :)

Answer 2

The correct answer is D. amino acids.

Miller and Urey were the ones who tested the chemical origin of life and they supported the theory that the life is formed spontaneously through naturally occurring chemical reactions. They designed the experiment in which the conditions of Earth's early atmosphere were simulated and showed that several organic amino acids had formed spontaneously from inorganic materials like water, methane, ammonia, and hydrogen.
