Which of the following best describes how the first organic molecules on the early Earth may have been formed?

Tidal flow and ocean currents helped mix molecules together so that they could react to build larger molecules.

Lightning provided the energy needed for gases to react with each other and form amino acids.

Heat energy became trapped in the atmosphere by greenhouse gases and was used as an energy source in the building of macromolecules.

Enzymes catalyzed reactions between smaller organic molecules to form larger ones.

am i wrong?

D isn't the answer if you read this paragraph...

ok

Stanley Miller did an experiment in which he combined an atmosphere containing CH4 , H2, H2O, and NH3 in a reaction vessel. Using an electrical spark, he was able to generate several small organic molecules. To eliminate the criticism that microbial activity was the source of the organic compounds, Miller ran the experiment under sterile conditions and without an electrical spark. When no spark was used, no organic compounds were formed. When the experiment was conducted under sterile conditions, no organic compounds were formed.

Just skim it

its B?

stephstar101 · Answer

Since Miller's experiment many other similar experiments have been done with various atmospheric component combinations with similar results. All 20 of the most common amino acids have been produced by these types of experiments. In fact the experiments have been so successful under so many conditions that it is unlikely that organic compounds weren't formed in this manner!!!!

yup! according to this, it is!

The real answer for this question is...
Lightning provided the energy needed for gases to react with each other and form amino acids.
I just took the test and I got it right when I put this as my answer. I used your information.
