An experiment was done where a primordial soup of water, methane, carbon dioxide and ammonia was electrified. Following this, the material was found to contain many of the amino acids found in all living things on Earth.
 
  The purpose of this experiment was to: A) determine whether DNA could have formed from electrolysis.
  B) determine whether DNA could have formed from amino acids.
  C) determine whether DNA could have formed from water and methane.
  D) determine whether amino acids could have formed naturally on Earth.
  E) determine whether amino acids could have formed from water, methane, carbon dioxide and ammonia.

Question 2

In March 2004, a new world, Sedna, with a comet-like orbit and a perihelion over three times farther out than Pluto's was announced. What did this do to Pluto's status as a major planet?
 
  What will be an ideal response?

Answer to Question 1

D

Answer to Question 2

Although Sedna is probably not part of Pluto's Kuiper Belt, but a member of the even more distant and scattered Oort Cloud, the fact that it is almost as large as Pluto definitely made Pluto's hold on planet 9 status harder to defend.
