The theory of Endosymbiosis explains

• The origin of eukaryotes
• How species develop
• How bacteria live
• Why cells rely on one another

Miller and Urey's experiment suggests that...

• organic compounds necessary for life (amino acids) could have arisen from simpler compounds

• the sun powers all life

• primitive compounds can be made from super complex compounds

• applied pressure can form polypeptides

Which of these are the ingredients NEEDED for life to form?

• organic macromolecules/biomolecules

• atoms

• methane

• inorganic molecules

Miller/Urey and other scientists studying the origin of life have shown that:

• Formation of life on early Earth required material from space

• Simple cells can be produced in a laboratory using spontaneous generation

• Oxygen and water were present in the atmosphere to support life

• Organic molecules like amino acids and nucleotides could be produced from abiotic/inorganic molecules
