The characteristic that is not descriptive of C, would be D. It forms bonds with only itself. It forms bonds with almost all other nonmetals, present, like H,O,N, etc.
Answer:
It was significant because thanks to Miller's experiment, it was possible to test many years later and with modern techniques, the progress of the evolution of life on Earth.
Explanation:
In Miller's experiment, he subjected a mixture of methane, ammonia, hydrogen, carbon dioxide, nitrogen and water to strong electric shocks and high temperatures. He noted that organic molecules such as glucose, amino acids such as glycine, alanine, glutamic acid and aspartic acid were formed. Subsequently, in 2008 other scientists analyzed these compounds using more sensitive devices. Their analyzes found the formation of 20 amino acids (proteins) and 6 components found in the nucleus of the cells, thus checking the progress of the evolution of life on Earth.
The answer is A.
A: heat
plz give me brainliest <3
Noble gases are the least reactive of all elements. That's because they have eight valence electrons, which fill their outer energy level. This is the most stable arrangement of electrons, so noble gases rarely react with other elements and form compounds.
It is always the same as it was before the collision because there is no outside forces it is left with the same amount of energy throughout thee collision.
