The apparatus in the Miller-Urey experiment was used to mimic what?
proteins
Earth's present conditions
early Earth's conditions
they didn't mean to mimic anything in particular
What did the results of the the Miller and Urey experiment suggest? Life could have began:
in a pond from combinations of chemicals in the atmosphere and energy in amino acids
from RNA and then DNA
from organic compounds (amino acids) that could be made by heating and passing a electrical current, to stimulate lightning, through a mixture of gases.
when eukaryotes evolved from prokaryotes
What were the components of the Early atmosphere?
Nitrogen, Carbon Dioxide, Ammonia, methane, hydrogen, water
Nitrogen, Carbon Dioxide, Ammonia, amino acids, RNA
Nitrogen, DNA, proteins, Carbon Dioxide, hydrogen, water
The primordial soup hypothesis by Oparin suggests life began:
in a pond from combinations of chemicals in the atmosphere and energy in amino acids
from RNA and DNA
when eukaryotes evolved from prokaryotes
from organic compounds (amino acids) that could be made by heating and passing a electrical current, to stimulate lightning, through a mixture of gases.

What is the RNA world hypothesis and how does it explain the origin of life?
The RNA world hypothesis proposes that life on Earth originated from extraterrestrial RNA molecules.
The RNA world hypothesis suggests that early life on Earth was based on proteins instead of RNA.
The RNA world hypothesis states that RNA molecules were created after the origin of life on Earth.
The RNA world hypothesis suggests that early life on Earth may have been based on RNA molecules instead of DNA.
