To recreate an environment for biosynthesis, scientists included which element in their experiments? extremely cold temperatures oxygen ocean water mixtures of dissolved compounds and gases thought to be similar to earth's early atmosphere

Answer;

-Mixtures of dissolved compounds and gases thought to be similar to earth's early atmosphere

Explanation;

-Miller and Urey, conducted an experiment which demonstrated that several organic compounds could be formed spontaneously by simulating the conditions of Earth's early atmosphere. They designed an apparatus which held a mix of gases similar to those found in Earth's early atmosphere over a pool of water, representing Earth's early ocean.

-Therefore, to recreate an environment for biosynthesis, scientists included all of the following, unstable chemical conditions. sparks and also dissolved compounds and gases thought to be present in the early atmosphere.
