Origin of Life and Evidence of Evolution

Miller/Urey and other scientists have shown that:

•  Life on early Earth required material from space
• Cells survived in the primitive atmosphere
• Amino acids could be produced from inorganic molecules 
• Simple cells can be produced in a laboratory

What were the first organisms on Earth?

• plants

• fungi

• fish

• bacteria

Eukaryotes were created by this process:

• artificial selection

• endosymbiosis

• spontaneous generation

• aliens

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.
