organisms would not exist without water. Within the human body the majority of biological reactions require water to take place. Although it is possible for human survival without nutrients for up to several weeks‚ without water humans would die in a matter of days. In the human body‚ water makes up 60-70% of adult body weight. At cellular level water makes up between 70-95% of the mass of a cell. The amount of water in the human body is balanced. This balance is between water obtained from liquids consumed

Marukyan Extra Credit MGT 462/November 16‚ 2009 Water Conservation I have attended the presentation about water conservation techniques that each of us can use in our everyday life to ensure the sustainable development of resources and especially water. The presenter on the water conservation was a man who is in charge of the water preservation in Santa Monica. The presentation was very interesting and had great deal of information about proven water conservation tactics. The topics covered included

Drinking water or potable water is water safe enough to be consumed by humans or used with low risk of immediate or long term harm. In most developed countries‚ the water supplied to households‚ commerce and industry meets drinking water standards‚ even though only a very small proportion is actually consumed or used in food preparation. Typical uses (for other than potable purposes) include toilet flushing‚ washing and landscape irrigation. Chlorination is the process of adding the element chlorine to water as

Water Transport The movement of plants from water to land has necessitated the development of internal mechanisms to supply all the parts of the plant with water. As discussed in Plant Classification‚ Vasular Tissues ‚ tracheophytes (including virtually all terrestrial plants except for mosses and liverworts)‚ have developed complex vascular systems that move nutrients and water throughout the plant body through "tubes" of conductive cells. The vascular tissues of these plants are called xylem

WATER RESOURCES The sources of water that are useful to human life are called water resources. Uses of water include agricultural‚ industrial‚ household and recreational activities. The majority of human uses require fresh water. 97 percent of the water on the Earth is salt water and only 3 percent is fresh water; slightly over two thirds of this is frozen in glaciers and polar ice caps. The remaining unfrozen fresh water is found mainly as groundwater‚ with only a small fraction present above

Thesis Statement: Water pollution is bringing down the economy‚ destroys the beauty of nature‚ and causing harmful dreaded diseases and sickness in precious health of many individual. INTRODUCTION Water pollution progresses every day in our lakes‚ oceans‚ rivers‚ and other bodies of water that we see and use in many ways. Water is essential for all living things to survive‚ yet people still pollute it. It’s pretty sad to be taking a trip to the beach with your family and you get there to see

Deionized Water vs. Distilled Water Deionized and distilled waters are both processed forms of water. Deionized water is produced by filtering water to the point where it is free of ions. This ion-free water will strip ions from surrounding material‚ acting like a super-solvent. This is often used in semiconductor and other high-tech processing as a "soft" solvent and relatively cheap cleaning fluid. Distilled water is most often produced by vaporizing less pure source water (tap‚ salt or even

Salt Water or Fresh Water‚ Which Would You Prefer? Many people wonder‚ what big differences are between salt water and fresh water? Is it just water with salt versus water without salt? Those are some common questions people have. Most people ask about the differences‚ but they forget about the similarities of salt water and fresh water‚ as well. Did you know that Salt water and fresh water have very different plant and animal life? There are also a few complex fish that can live in both

Tap Water Vs Bottle Water Tap Water: Tap water is the most efficient water available. Unfortunately‚ it is also vulnerable to occasional contamination. This is usually locally due to damaged pipes. This type of problem can be fixed in a timely manner. For the most part‚ the water is not much different from bottled water. It can be consumed directly from the pipes without harm. Even when the water is contaminated it is usually not fatal. Water pipes efficiently carry water across the nation as

Introduction Water is necessary to life but it can be unhealthy too. In general‚ the water quality is poor in developing countries like Kenya. Water is a vector of diseases like yellow fever‚ diarrhea… Water purification is very important in these countries but people don’t have a lot of time to spare‚ they work or they are in the field and in general women must spend a significant amount of time walking to collect water. So we need to find a quick‚ easy‚ and economic solution that is as simple
