muminat

Answer:

The answer is; Simulation of early Earth conditions and long-term study of the resulting molecules

Explanation:

It is believed that the first molecules on earth were made spontaneously through reaction spurred by energy from lightning and also the heat from the earth. It is believed that these molecules over time then formed polymers through the catalysis by metals in the oceans. These polymers were able to self-replicate and also act as enzymes since they were able to fold up. This hypothesis was coined by Carl Woese, Francis Crick and Leslie Orgel in the 1960s. To prove it, the then conditions of early earth need to be replicated, data collected, and analyzed.

How do ATP and ADP compare? A. ATP has one fewer phosphate group and is lower in energy than ADP. B. ATP has one fewer phosphate
Lady bird [3.3K]
D. ATP (Adenosine TRIphosphate) has one more phosphate group and is higher in energy than ADP (Adenosine DIphosphate). TRI means three, DI means two, so the names of the molecules tell you there's one more phosphate in ATP than in ADP. 

That extra phosphate makes ATP higher in energy (when the cell uses that energy to do something - contract a muscle fiber, for instance - the ATP's extra energy is used and it gets converted to ADP).
