Why the miller-uray experiment have not proven that life could have risen from nonliving materials?
The Miller-Urey experiment did not accurately simulate Earth's early atmosphere. Additionally, the experiment produced a mixture of organic compounds, not living organisms. Life is incredibly complex and likely required many more steps beyond what was demonstrated in the experiment.
In miller and urey's experiments with the origin of life-forms electric sparks were passed through a mixture of gases to?
through simulate lightning
What could replace lightning in the miller-urey experiment?
In the Miller-Urey experiment, a high-energy source such as UV light or electric sparks could replace lightning to simulate the energy input needed for chemical reactions to occur. These energy sources can help drive the formation of simple organic compounds from inorganic molecules, similar to what may have happened on early Earth.
In Miller and Ureys experiments with the origin of life forms electric sparks were passed through a mixture of gases to?
simulate the conditions of early Earth and test whether organic molecules could be formed from inorganic compounds. The experiment produced amino acids, which are the building blocks of proteins, demonstrating that the basic components of life could have originated from non-living matter under early Earth conditions.
What does a Miller Urey synthesis refer to?
A simulation of the origin of life.
Why were urey and miller send an electric current through the mixture?
Urey and Miller sent an electric current through the mixture to simulate the energy from lightning strikes in the atmosphere of early Earth. This was done to test the hypothesis that such energy could have fueled the chemical reactions necessary for the formation of organic molecules, such as amino acids.
What compounds were used in Miller and Urey's experiment to simulate the atmosphere of early Earth?
Miller and Urey's experiment used a mixture of gases including methane, ammonia, hydrogen, and water vapor to simulate the atmosphere of early Earth. These compounds were believed to represent the conditions present on Earth billions of years ago prior to the presence of oxygen.
What were the components used to recreate the primitive earth atmosphere in Miller and Urey experiment?
The Miller-Urey experiment used water (H2O), methane (CH4), ammonia (NH3), and hydrogen (H2) to recreate the primitive Earth's atmosphere. These components were sealed in a glass apparatus and subjected to electric sparks to simulate lightning, producing simple organic molecules like amino acids.
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.

What did the sparks urey and miller use as the energy source represent for their experiment?
The sparks used as the energy source in the Miller-Urey experiment represented lightning strikes in the early Earth's atmosphere. This was meant to simulate the energy provided by natural electrical discharges, which were essential to the synthesis of organic compounds from inorganic molecules in the primordial environment.
Why did miller and urey put those particular gases into their experiment?
Miller and Urey put methane, ammonia, hydrogen, and water vapor into their experiment to simulate the atmosphere believed to be on early Earth. These gases were chosen because they were thought to be the most abundant at that time and conditions.

What is the independent and dependent variable in miller-urey's experiment?
INDEPENDENT VARIABLE: gases introduced in the experimental chamber [Methane, Hydrogen and Ammonia). DEPENDENT VARIABLE: the outcomes of the experiment. CONTROL VARIABLE: the amount of gas introduced, the amount of water, the percentage of humidity in the chamber etc.
What does a Miller Urey synthesis refer to?
A simulation of the origin of life.
