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.
Uranus have extreme seasons due to its unique tiltation of 82 degrees
<h3>Why does Uranus have extreme seasons?</h3>
The orbit of Uranus is circular which maintains the same distance from the Sun throughout year. But Uranus is tilted about 82 degrees which gives rise to extreme 20-year-long seasons and unusual weather.
So we can conclude that Uranus have extreme seasons due to its unique tiltation.
