If so, then electricity is simply the charges already inside the wires, where a flow of electricity is a flow of charge. And therefore we must say that the electricity sits inside the wires and vibrates back and forth. Generators do not create any, and electricity does not flow forward through the wires.
Despite the variety of colors and patterns, cats come in three basic colors: red, black, and white. Everything else is a variation of red and black. Now, red encompasses what many people call orange, ginger, yellow and marmalade. Another important point is that solid colors can also be diluted.
Cat's skin has the same color as the fur but the color of the nose leather is probably dictated by a dedicated gene. Cats with white fur have skin susceptible to damage by ultraviolet light that may cause cancer. Extra care is required when outside in hot sun.
