Question

A glass dish containing a few drops of water in the presence of carbon dioxide gas, nitrogen gas, and small organic compounds is heated by a flame and UV radiation. Which early Earth scenario does this set-up most closely resemble?

Answer 1

Deep sea volcanoes giving off gases, sulfur, and iron to produce organic molecules

Lightning in the early atmosphere, which may have produced the first organic molecules

The replication of RNA near the ocean's surface in the day and night cycling of temperatures

Amino acid formation from organic molecules in ocean water splashing on hot rock, sand, or clay

Can you explan why? @Gabebro13

Answer 11

Uh, sure. A long time ago in this same galaxy...
AT the beginning of the world or whatever, there were no organic modules. The atmosphere was full of lightning and the air couldn't support life. Then after some amount of compounds and radiation, life formed. These were auto trophs that created energy with a process similar to photosynthesis and expelled oxygen. Other organisms later arised using that oxygen. Then the atmosphere formed. Etc. etc.
