Cycles in Biology Cycles in biology play a fundamental role in the world that we live in. Cycles occur all around and inside of us in many different forms‚ from the Krebs to the Calvin cycle. There are large scale cycles happening and they are essential in regulating the nutrients and substances that are around us which without‚ life on earth could no function. One of the largest cycles that occurs all around us is in everyday life is the carbon cycle. The current atmospheric

where does the water cycle gets its energy from? the water cycle gets the energy from the sun. why do we need the water cycle? since 97% of the earth is covered by salt water we can not drink it. we can remove salt from water but it could be very expensive. how does water get into oceans? when clouds can’t hold any more water it comes as precipitation and lands in the ocean. what is the water cycle made up of? it is made up of six different traits. condensation‚infiltration‚runoff‚ evaporation‚ precipitation

CHAPTER 12- THE CELL CYCLE I. Concept 12.1- Cell division results in genetically identical daughter cells A. Overview 1) The continuity of life is based on the reproduction of cells or cell division. 2) The cell division process is an integral part of the cell cycle‚ the life of a cell from the time it is first formed from a dividing parent cell until its own division into two cells. B. Cellular Organization of the Genetic Material 1) A cell’s endowment of DNA‚ its genetic

------------------------------------------------- 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

The business cycle is like a roller coaster and this roller coaster definitely has its dips and peaks. In the cycle there are expansionary periods‚ peaks‚ downturns‚ and troughs. Each one is part of and essential in the cycle. Like a roller coaster you will go up and reach a peak and then you will have to drop. Although just because you drop does not mean you will reach the lowest point of the ride. Just like a coaster the business cycle has its high peaks and plunging drops. So lets start the

The rock cycle involves of a chain of continual progressions through which earth materials change from one form to another over time. Some processes in the rock cycle happen over millions of years and others occur much more quickly. There is no real starting or completion to the rock cycle; however‚ it may be appropriate to begin investigating the rock cycle with magma (Bergman 2005). Magma‚ or molten rock‚ forms only at certain locations within the earth‚ mostly along plate boundaries. Magma crystallizes

Nitrogen cycle Nitrogen gas is a colourless‚ odourless and non-toxic gas which makes up about 78 percent of the atmosphere. Nitrogen is extremely important to living material; in fact plants‚ animals and humans could not live without it. Sprent (1987) argued that nitrogen cycle is the most important process to living organisms after the carbon cycle. But nitrogen exists as dinitrogen (N2) in the atmosphere‚ which living things‚ particularly plants‚ cannot synthesize (citation) The process of nitrogen

A cycle is defined as any complete round or series of occurrences that repeats or is repeated in the same order and at the same intervals. The natural existence of cycles is highly important without cycles resources would run out and organisms would die. The amount of carbon nitrogen and oxygen on the earth is fixed‚ they can exists in different forms but no more may be added. So that these don’t run out they are cycles so they may be reused. Photosynthesis and respiration are the reverse of each

THE WATER CYCLE Introduction: The water around us has been All the water around is has been here for many‚ many years. The reason is because the same water is just around a cycle. There are several steps in this cycle. In my opinion‚ this is a very interesting and fun project to do. Problem: What is the water cycle? Research: Water is vital for every living thing. When the Sun heats‚ it causes the water in the oceans‚ ponds‚ lakes and even puddles in the street to warm and evaporate

The Brayton Cycle (Jet Engine) Purpose and Objective: The purpose and objective of this experiment is to understand the basic operation of a brayton cycle also to demonstrate the application of basic equations for Brayton cycle analysis. Technical Background: The Brayton cycle depicts the air standard model of a gas turbine power cycle and is used in all applications involving turbine engines; such as jet engines. A simple gas turbine is comprised of three
