The Miller-Urey experiment was a 1 point
famous experiment designed to
test whether life on early Earth
could have been created by the
energy of lightning causing
gaseous molecules in Earth's
atmosphere to combine into
amino acids. The experiment
created a model of life on early
Earth by using a set of gases and
a spark of electricity to represent
lightning. The diagram below
shows how the experiment was
set up. What combination of
gases should the experiment
have used?
