What did the miller urey experiment demonstrate

It demonstrated what Early Earth was like long ago, when organisms were basic. They tested what organisms were alive and what they were like.

The Miller and Urey experiment was based on the origin of life. The experimented demonstrated that the important molecules of life were made on the earth with the similar conditions which were stated by Oparin and Haldane hypothesis.

Explanation:

The Oparin and Haldane suggested that the life is originated from simple inorganic molecules. To prove this hypothesis, Miller and Urey performed a experiment to show that organic molecules are formed from inorganic molecules.

The experiment was performed by providing similar conditions of reducing atmosphere. The methane, water, ammonia and hydrogen were used in the experiment and electrodes were placed for electric discharge. Thus, it results in the formation of five amino acids.

the element that provides strength to the exoskeletons of clams and oysters is phosphorus.

this is so because calcium carbonate is the main component in the shells. calcium carbonate is strengthened by phosphorus.

explanation:

true, i don't really know what you're asking but from the info you provided im guessing the answer is true.
