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
through simulate lightning
A simulation of the origin of life.
Harold Urey and Stanley Miller used a mixture of gases such as methane, ammonia, water vapor, and hydrogen to simulate the early Earth's atmosphere in their laboratory experiments. They then subjected this mixture to electrical sparks to mimic lightning, creating amino acids and other organic compounds, potentially similar to those that could have formed on early Earth.
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.
They simulated lightning in the early earth's atmosphere. The reasoning being that the reactions required some form of energy input to begin, and that lightning would have almost certainly been present.
Miller and Urey's experiments attempted to demonstrate the chemical origins of life. They first conducted the experiment in the year 1953.
through simulate lightning
A simulation of the origin of life.
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.
The origin of life.
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.
I think you have Miller and Urey confused with someone else.
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.
The Miller-Urey experiments provided support for the hypothesis that the complex molecules necessary for life could arise from simpler compounds present on early Earth. This is important for understanding how life could have potentially originated through chemical processes on the planet.
Miller and Urey
The end products in Miller and Urey's experiments were various organic compounds, such as amino acids, sugars, and lipids. These molecules are building blocks of life and were synthesized in the experimental setup that simulated early Earth's conditions.
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.
