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?

a. amino acid formation from organic molecules in ocean water splashing on hot rock, sand, or clay
b. deep sea volcanoes giving off gases, sulfur, and iron to produce organic molecules
c. lightning in the early atmosphere, which may have produced the first organic molecules
d. the replication of RNA near the ocean's surface in the day and night cycling of temperatures

Answer 1

The correct answer is (a )

This experiment shows that the life has evolved from the inorganic materials. The substances like carbon dioxide, nitrogen gas when heated and exposed to UV radiation led to generation of life supporting element called as amino acids. The UV radiation and heat provided the energy needed by gases to convert into amino acids.
