Answer:
The very first DNA isolation was done by a Swiss physician, Friedrich Miescher in 1869. He hoped to solve the fundamental principles of life, to determine the chemical composition of cells.
The answer is true, Sponges can regenerate the entire organism from just a conglomeration of their cells. They can be cut up or mashed, and as long as they have two special cells called collencytes, which produce the gelatinous matrix in the sponge, and archeocytes, which produce all the other cells in the spongeâ??s body, the sponge will reform into the sponge it once was. Although, it will look different. Hope it helps!
The reason the socks stick together, is because electrons from one fabric rub off onto another fabric by friction.
The presence of inorganic molecules is the meteorite condition in space similar to what was likely present in Earth's early atmosphere.
The earth initial atmosphere in its early form was too reducing and it was made up entirely of gases such as carbon monoxide, ammonia, methane, nitrogen and other gases.
This atmosphere did not have free oxygen, since it was the result of the mixture of metals, hydrogen and other chemical elements.
The high temperatures, ultraviolet rays and electrical discharges in the early atmosphere would have caused chemical reactions of the elements to form primitive organic molecules.
Meteorites are fragments of solid matter that contain a record of the chemical substances that existed in the early Solar System.
The most predominant gases still found in the space are hydrogen and helium.
Therefore, we can conclude that hydrogen and the presence of inorganic molecules are the initial elements that make up the Earth's early atmosphere and that they are conditions that are present in the space and so in the formation of meteorites.
