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. Water on our planet can be stored in any one of the following major reservoirs: atmosphere‚ oceans‚ lakes‚ rivers‚ soils‚ glaciers‚ snowfields‚ and groundwater. Water moves from one reservoir to another by

The water cycle is also known as the hydrologic cycle. The water cycle describes the movement of water on‚ above and below the surface of Earth. Water can change states through the stages of the water cycle. Water can change from a solid to a liquid to water vapor in various places of the water cycle. Water moves from one lake to another‚ just like from an ocean to the atmosphere. Water travels by different processes of evaporation‚ condensation‚ precipitation‚ infiltration‚ runoff and subsurface

When business fluctuations are positive they are called expansion‚ the opposite of expansion is contraction which is slow down in the pace of national economic activities. Phases of the business cycle over a several year period 1. A peak is when business activity reaches a temporary maximum with full employment and near

Each Hype Cycle drills down into the five key phases of a technology’s life cycle. 1. Technology Trigger: A potential technology breakthrough kicks things off. Early proof-of-concept stories and media interest trigger significant publicity. Often no usable products exist and commercial viability is unproven. 2. Peak of Inflated Expectations: Early publicity produces a number of success stories—often accompanied by scores of failures. Some companies take action; many do not. 3. Trough of Disillusionment:

Water is continuously being recycled in a process called the water cycle. All living things on earth need water to survive. The water cycle has no starting point and no end point. Earth’s water is always in movement and always changing forms‚ it can go from a liquid to a solid to a gas and back to a liquid. The water cycle is how we track movement of water above‚ in and on the earth. The water cycle consists of three major processes‚ condensation‚ evaporation and precipitation. Condensation is the

------------------------------------------------- The Processes of the nitrogen cycle Nitrogen fixation Atmospheric nitrogen must be processed‚ or "fixed" (see page on nitrogen fixation)‚ in order to be used by plants. Some fixation occurs in lightning strikes‚ but most fixation is done by free-living or symbiotic bacteria. These bacteria have the nitrogenase enzyme that combines gaseous nitrogen with hydrogen to produce ammonia‚ which is then further converted by the bacteria to make their own organic
