Coal is a combustible black rock that is formed from prehistoric plant remains. Coal is formed from the anaerobic decomposition of dead plant matter such as trees, ferns, mosses and other marsh plants that grew on the earth surface over millions of years ago. Coal is composed largely of carbon and is usually burned as a fuel.

<span>Most membrane channels allow passage by simple diffusion of small inorganic ions of a specific type and may also be voltage gated. The solute binds to a protein carrier on one side of the membrane and is released on the other side after the transporter undergoes a change in shape, the movement of molecules across a cell membrane from a region of their lower concentration to a region of their higher concentration in the direction against some gradient or other obstructing factor.</span>
