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.

How did miller and Urey model the conditions in earth's early atmosphere?
Miller and Urey modeled the conditions of Earth's early atmosphere by creating an experiment that simulated the atmosphere of primitive Earth. They used a mixture of gases like ammonia, methane, and water vapor, and subjected it to electrical discharges to simulate lightning. This experiment produced organic compounds, including amino acids, building blocks of life.
In addition to hydrogen the gases used in miller and urey's experiment were?
In Miller and Urey's experiment, the other gases used were methane, ammonia, and water vapor, which were believed to represent the early Earth's atmosphere. These gases were subjected to electrical sparks to simulate lightning, which produced a variety of organic compounds, including amino acids, which are the building blocks of proteins.
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.
How did Miller and Uray model the conditions in earths early atmosphere?
Miller and Urey modeled the conditions of Earth's early atmosphere by recreating a mixture of gases believed to be present during that time period, such as methane, ammonia, hydrogen, and water vapor. They then subjected this mixture to electric sparks to simulate lightning, which resulted in the formation of simple organic compounds like amino acids, the building blocks of life.
What 2 scientists set up an experiment that simulated the atmosphere of early earth?
Stanley Miller and Harold Urey set up the famous Miller-Urey experiment in 1953, which simulated the early Earth's atmosphere. They used a mixture of gases like ammonia, methane, and water vapor, and applied electrical sparks to mimic lightning. The experiment produced amino acids, the building blocks of life, showing that organic molecules could have formed on early Earth.
Urey and miller used an electric current in their experiment to simulate?
Urey and Miller used an electric current in their experiment to simulate the effects of lightning in the early Earth's atmosphere. They wanted to see if the combination of gases found in the atmosphere at that time could produce organic compounds like amino acids, which are the building blocks of life.
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.
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.

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 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 it was the purpose of Miller and Urey's experiment?
The purpose of the Miller-Urey experiment was to simulate early Earth conditions and investigate the origin of life by creating amino acids, the building blocks of proteins, through the use of electricity to mimic lightning in a reducing atmosphere. This experiment aimed to provide evidence for the abiotic synthesis of organic compounds, supporting the hypothesis that the essential building blocks of life could have formed on early Earth.
In addition to hydrogen the gases used in miller and urey's experiment were?
In Miller and Urey's experiment, the other gases used were methane, ammonia, and water vapor, which were believed to represent the early Earth's atmosphere.

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.
Why Urey-Miller experiment so important?
The Urey-Miller experiment was important because it demonstrated that complex organic molecules, such as amino acids, could be formed under conditions replicating early Earth's atmosphere. This supported the idea that the building blocks of life could have formed spontaneously on Earth, potentially laying the foundation for the origin of life.
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.
