The cell cycle‚ or cell-division cycle‚ is the series of events that take place in a cell leading to its division and duplication that produces two daughter cells. In cells without a nucleus‚ the cell cycle occurs via a process termed binary fission. In cells with a nucleus‚ the cell cycle can be divided in three periods: interphase—during which the cell grows‚ accumulating nutrients needed for mitosis preparing it for cell division and duplicating its DNA—and the mitotic phase‚ during which the

Hydrological Cycle Hydrological cycle is the process that involves the continuous circulation of water in the Earth-atmosphere system. The hydrologic cycle is a conceptual model that describes the storage and movement of water between the biosphere‚ atmosphere‚ lithosphere‚ and the hydrosphere.
