Answer:
The Miller-Urey experiment was conducted to simulate the conditions on Earth when life arose, and see if a chemical evolution could occur. This experiment was performed without oxygen, because they knew that if oxygen was added, the amino acids would oxidize. In particular, the experiment intended to simulate a volcanic eruption was analyzed.
Thus, particles of water, methane, ammonia and hydrogen were exposed to high temperatures and electric discharges that simulated these eruptions, during a determined period. Later, it was observed that organic compounds had emerged from this exposure, which allowed us to infer one of the hypotheses regarding the origin of life on Earth.

There isn't a specific 'most common eating disorder', but most people would have a disorder known as binge eating disorder, which is eating more than necessary. The other top 2 include anorexia nervosa or bulimia nervosa.
1. Topographic map: I want to take a nature hike through the woods. I wonder if it is hillly?
2. Geologic Map: I want to study the physical features of my area, but also know what kinds of rocks it has.
Those should be the answers.
Hope this helped :) Have a great day
