Miller and Urey were trying to answer the question of how life could have originated from non-living chemical substances on the early Earth. Their famous experiment simulated the conditions of the primordial Earth, including a reducing atmosphere and energy sources like lightning, to see if organic compounds essential for life could be formed. They aimed to provide evidence for the abiotic synthesis of organic molecules, which could lead to the emergence of life.

What did oparin Haldane Miller and Urey accomplish?
Oparin, Haldane, Miller, and Urey contributed significantly to our understanding of the origin of life on Earth. Oparin and Haldane proposed the primordial soup theory, suggesting that life began in a reducing atmosphere rich in organic compounds. Miller and Urey conducted a famous experiment in 1953 that simulated early Earth conditions, demonstrating that amino acids and other organic molecules could form from simple inorganic precursors. Their work laid the foundation for research into abiogenesis and the chemical origins of life.
What is Harold C. Urey's birthday?
Harold C. Urey was born on April 29, 1893.
What is Stanley miller facts?
Stanley Miller was an American chemist best known for the Miller-Urey experiment conducted in 1953, which simulated early Earth conditions to explore the origins of life. The experiment combined water, methane, ammonia, and hydrogen, using electrical sparks to mimic lightning, resulting in the formation of amino acids, the building blocks of proteins. This groundbreaking work provided evidence that organic compounds necessary for life could form from simple inorganic precursors under the right conditions. Miller's findings have had a lasting impact on the fields of biochemistry and astrobiology.
What did Harold C Urey do?
well i am almost positive that he helped made the atomic bomb and helped figure out what and when the first life was
Where did Harold urey work?
Harold Urey worked at several prestigious institutions throughout his career, including Columbia University, where he conducted much of his groundbreaking research. He also worked at the University of Chicago, where he contributed to the Manhattan Project during World War II. Additionally, Urey spent time at the California Institute of Technology (Caltech) and was involved in various government and research organizations.
What did miller and urey find in Greenland?
I think you have Miller and Urey confused with someone else.
Miller and urey's experiments attempted to demostrate?
Miller and Urey's experiments attempted to demonstrate the chemical origins of life. They first conducted the experiment in the year 1953.
What does a Miller-Urey synthesis refer to?
A simulation of the origin of life.
How did Oparin's hypothesis help Miller and Urey?
Oparin's hypothesis proposed that Earth's early atmosphere could have supported the formation of organic molecules, providing the foundational idea for Miller and Urey's experiment. Miller and Urey's experiment aimed to simulate early Earth conditions and demonstrated that organic molecules, including amino acids, could indeed be produced in a laboratory setting, supporting Oparin's hypothesis.
Where did the miller urey experiment happen?
it happend on christmas day. it was a big suprise
Who were Stanley Miller and Harold Urey?
Stanley Miller and Harold Urey were two scientists who send electrical currents through gases that were believed to be Earth's early atmosphere (water vapor, ammonia, hydrogen, and methane). When the gases cooled, they thickened to make a salt water-like liquid that had things in it like amino acid, what is found in present-day cells.
Which putative early Earth condition did Miller and Urey's experimental apparatus not attempt to stimulate directly?
He deliberately left out oxygen knowing it would destroy the amino acids he was trying to make.
Which gases were conducted in urey and miller experiments?
1. Miller and Urey's organic experiments suggested how mixtures of the organic compounds necessary for life could have arisen from simpler compounds present on a primitive earth haha i found this in our textbook, miller levines textbook :PP
What was the purpose of Miller in Urey experiment?
The purpose of the Miller-Urey experiment was to simulate the conditions of early Earth to investigate the origins of life. They wanted to test whether organic molecules, such as amino acids, could be formed from inorganic compounds under these conditions.
Organic compounds will not form in the Miller-Urey apparatus if O2 is present Why is this not?
Organic compounds will not form in the Miller-Urey apparatus if O2 is present because oxygen would react with the organic molecules produced, inhibiting the formation of more complex organic compounds. The early Earth's atmosphere was believed to be devoid of oxygen, which allowed for the formation of organic compounds in the Miller-Urey experiment.
What does a Miller Urey synthesis refer to?
A simulation of the origin of life.
In the Miller-Urey experiment what was used as energy source to drive chemical reactions?
Electrical discharge
