Question

select each component of chemical evolution theory from the choices below.
an energy source, such as sunlight
the presence of decaying matter
very different, oxygenless atmosphere
molecules are built from simple to complex.

Explanation:

Chemical evolution theory describes how simple inorganic molecules evolved into complex organic molecules (the precursors of life) on early Earth. Key components include an energy source to drive reactions, an oxygen-free (reducing) early atmosphere, and the gradual building of complex molecules from simple ones. Decaying matter is not a component, as it requires existing life, which chemical evolution precedes.

Answer:

• An energy source, such as sunlight
• Very different, oxygenless atmosphere
• Molecules are built from simple to complex.
