I don't know about the other ones but the sky is blue because molecules move from the sun than the red from the sun. The blue has separated from the sun.
Mid ocean ridges occur where two tectonic plates diverge or move away from each other. This separation occurs under the ocean.The Mid-Atlantic Ridge is such an example and is where the North and South American plates pull away from the Eurasian and African plates. Mid ocean ridges are usually a combination of divergent and transform plate boundaries. At transform boundaries plates slide past each other in opposite directions.
Active transport is a process requiring energy in which a substance crosses the cell membrane. When the nerve cell is in its resting potential, there are the positively charged sodium ions and the negatively charged potassium ions. During depolarization, the neuron fires, wherein the active transport plays its role: the positive ions are forced in and the negative ions are forced out. When depolarization is done, these ions are again back to normal through active transport.<span>
