Answer 1

In his laboratory apparatus, Stanley Miller synthesized amino acids.

Explanation:

Stanley Miller, in his famous 1953 experiment with Harold Urey, simulated the conditions of the primitive Earth using a spark-discharge apparatus containing gases like methane, ammonia, hydrogen, and water vapor. After running the experiment for a few days, they were able to synthesize amino acids such as glycine, alanine, and aspartic acid, which are the building blocks of proteins.
