Oxygen cycle From Wikipedia‚ the free encyclopedia Jump to: navigation‚ search The oxygen cycle. The Oxygen cycle is the biogeochemical cycle that describes the movement of oxygen within its three main reservoirs: the atmosphere (air)‚ the total content of biological matter within the biosphere (the global sum of all ecosystems)‚ and the lithosphere (Earth ’s crust). Failures in the oxygen cycle within the hydrosphere (the combined mass of water found on‚ under‚ and over the surface of a planet)

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

The Carbon Cycle is a complex series of processes through which all of the carbon atoms in existence rotate. The same carbon atoms in your body today have been used in countless other molecules since time began. The wood burned just a few decades ago could have produced carbon dioxide which through photosynthesis became part of a plant. When you eat that plant‚ the same carbon from the wood which was burnt can become part of you. The carbon cycle is the great natural recycler of carbon atoms. Unfortunately

Elena Chen CH 221-227 November 3rd‚ 2009 Lab Report #3: Copper Cycle Abstract: The purpose of the experiment is to cycle solid copper through a series of five reactions. At different stages of the cycle‚ copper was present in different forms. First reaction involves reaction between the copper and nitric acid‚ and copper changed from elemental state to an aqueous. The second reaction converted the aqueous Cu2+ into the solid copper (2) hydroxide. In the third reaction Cu(OH)2 decomposed into

Cardiac Cycle The cardiac cycle describes the coordinated and rhythmic series of muscular contractions associated with the normal heart beat. The cardiac cycle can be subdivided into two major phases‚ the systolic phase and the diastolic phase. Systole occurs when the ventricles of the heart contract. Accordingly‚ systole results in the highest pressures within the systemic and pulmonary circulatory systems. Diastole is the period between ventricular contractions when the right and left ventricles

. Many products and services often pass a life cycle while there are many shapes depending on their industries. They newly emerge in the society‚ start to sell to be widespread‚ become saturated in the market and then gradually get out of date. This sequence of product and service is called the product life cycle. Smartphone also passes such natural path. According to the next web (2011)‚ first smartphone brand was Ericsso’s GS88 in 1997. A touchscreen smartphone‚ which is widespread now‚ was launched

Since the water cycle is truly a "cycle‚" there is no beginning or end. Water can change states among liquid‚ vapor‚ and ice at various places in the water cycle‚ with these processes happening in the blink of an eye and over millions
