Which statement is false?
Oxygen attacks chemical bonds and extracts electrons, which prevents the formation of complex molecules.
Experiments like Miller and Urey’s do not work in the presence of oxygen.
Oxygen was abundant in the earth’s early atmosphere, before the origin of life.

Oxygen was abundant in the earth’s early atmosphere, before the origin of life.

Explanation:

It is false to say that Oxygen was abundant in the earth’s early atmosphere, before the origin of life.

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a
