Urey and Miller attempted to mimic conditions on early Earth to illustrate how the origin of life may have occurred billions of years ago. Which statement would provide the most evidence that early Earth's conditions were suitable for the formation of carbon-based life?

A) Liquid from the sampling probe contained more than twenty different amino acids.

B) The pH of the ocean waters was more acidic with less salinity than oceans today.

C) The atmosphere contained heavy isotopes of hydrogen, like tritium, in the water molecules.

D) The air sampled from the primitive atmosphere contained diatomic nitrogen rather than ammonia.

Grayson Mathis · Answer 2

The correct statement is liquid sample from the sampling probe containing more than twenty different amino acids.

Explanation:

The experiment is done by Miller - Urey in 1952 to create the atmosphere similar to the ancient time of earth's atmosphere to discover whether there was any similarity or not.

This experiment shows 20 different amino acids that are produced in the experiment and also gives the idea that earth's original atmosphere had different from gas that is used in Miller's experiment.
