Diffusion occurs because of the ________________________ of molecules.
rosijanka [135]
Diffusion occurs because of the movement of molecules from the region of higher concentration to the region of lower concentration. This movement of molecules occurs due to a thermal motion. Diffusion normally occurs between two compartments having difference in concentration. In case of fluid it moves from the region of higher concentration to the region of concentration until a balance is reached. The process of diffusion is very important for the humans as well. The oxygen that humans breathe in gets diffused with the blood.

how would you answer a person who says that the geologic column gives support for an earth that is at least 4.6 billion years ol
liubo4ka [24]
<span>The geologic column is a graphic representation of the layers of rock that make up the earth’s crust. By compiling data from local areas, scientists have constructed a composite picture of the earth. Evolutionists would have us believe that this is also a picture of the 4.5 billion year history of the earth. Using a bit of circular reasoning, the geologic column is used as support for biologic evolution, which is then sometimes used to confirm the order of the layers in the geologic column.</span>
