Which statement correctly describes how the first life on earth could have occurred by spontaneous generation?
In an environment with a high concentration of methane, a carbon-based
molecule, carbon chains of increasing length could have formed. Because life is
carbon-based, life could have resulted from this process.
In an environment without free oxygen, amino acids, nucleic acids, and lipids
were able to increase in number. In large amounts, these molecules could have
formed simple life forms.
The energy from lightning striking the ocean caused free elements to fuse
together in a permanent bond. Eventually, the combination of these molecules
over time formed primitive life.
In an environment that contained ammonia, the nitrogen became part of amino
acid, nucleic acid, and lipid molecules. These are the components of life forms.
