question 9
the atmosphere on early earth (4.5 to 3.8 billion years ago) ____________.
consisted of a combination of gases, including free oxygen
was filled with uv radiation, which did not allow the formation of molecules
created unfavorable conditions for forming chemical bonds
allowed the chemical processes that led to early life

Explanation:

Early Earth's atmosphere lacked free - oxygen. It had gases that participated in chemical reactions which were crucial for the emergence of early life. UV radiation was present but molecules still formed, and the conditions were favorable for chemical bond formation and the chemical processes leading to life.

Answer:

allowed the chemical processes that led to early life
