Answer:
Urey and miller cooked a "primordial soup" with Hadean gases, water and electricity to make <u>glucose</u>, <u>acetic acid</u>, <u>amino acids</u> and <u>lipids</u>.
Explanation:
In the Miller-Urey experiment, the aim was to reproduce the conditions of the earth before the existence of life, with the objective of demonstrating the formation of organic matter from inorganic molecules.
The scientists took water and gases present in the Hadean eon —previous to the existence of life— such as methane, carbon dioxide, hydrogen, nitrogen and even ammonia, the primordial soup. This mixture was subjected to electrical discharges, inside closed containers.
The results were some organic molecules, including glucose, acetic acid, amino acids and fatty acids. In these results the presence of macromolecules, such as proteins or nucleic acids, is not appreciated, however it was a significant contribution to the knowledge of the origin of life on earth.
Answer:
The fact that both strands are used as templates for DNA replication the response would be the first one.
For the answer to the question above,<span> a proposed explanation in evolutionary biology stating that species are generally stable over long periods of time is called "</span><span>punctuated equilibrium"</span> and occasionally there are rapid changes that affect some species which can quickly result in a new species.
The answer is <span>"</span><span>punctuated equilibrium"</span>
