1953, Stanley Miller and Harold Urey built a model of Earth's earlyatmosphere by mixing gases that were thought to have been there. Theyexposed the gases to an electric current to simulate lightning. The liquid thatcondensed during the experiment contained amino acids.What was the significance of their results?OA. Miller and Urey showed that biological molecules could haveformed from the atoms present in the early atmosphere.B. Miller and Urey showed that spontaneous generation waspossiblec. Miller and Urey showed that lightning was necessary for life to inform on Earth.OD. Miller and Urey showed that all life evolved from a single common

Sagot :

Let's take a closer look at the context of the problem:

We are given that Miller and Urey ran an experiment trying to determine whether Earth's early atmosphere could have created the building blocks of life as we know it.

We are given the results of the experiment: amino acids were condensed in a liquid. Recall what amino acids are. Amino acids are the building blocks of life that form proteins. Proteins are necessary for day-to-day functions in an organism.

If in the experiment we did find amino acids, then we can speculate that life could have been formed from biomolecules formed from Earth's early atmosphere.

Recall that the context said that Miller and Urey did find amino acids in their experiment.

Therefore, our best answer choice for the problem is A. Miller and Urey showed that biological molecules could have formed from the atoms present in the early atmosphere.
