Answer 1

7)
- Stanley Miller — produced organic molecules from inorganic gases by simulating early-Earth atmosphere (Miller–Urey).
- Sidney Fox — produced energy-type molecules/proteinoid microspheres (often credited with protobiont/ATP-related experiments).

8) endosymbiosis

9) Methane and ammonia, needed for Miller's experiments, were likely not present in early earth.
