Consider the experiment that Stanley Miller did to simulate chemical evolution.Recall that a glass flask held the reduced gases NH₃,CH₄,and H₂ and that the gases were exposed to electrical sparks.What is the null hypothesis in the experiment?
A)Chemical evolution does not occur.
B)Chemical evolution requires the presence of reduced molecules.
C)Chemical evolution requires continuous heating.
D)Chemical evolution requires a source of kinetic energy.
E)Chemical evolution occurs only on Earth.

The null hypothesis in this experiment is that chemical evolution does not occur. This means that the experiment is designed to test whether or not the conditions present in the flask are sufficient to produce complex molecules from simple starting materials without the need for any additional input or intervention. The experiment is designed to test the possibility that chemical evolution could occur under certain conditions, but the null hypothesis is that it does not.
