Introduction Fresh water is an indispensable resource for human livelihood‚ agricultural irrigation and economic development (Brooks‚ 2007). However‚ due to the rapid population growth and the limited reserves‚ increasing regions have faced serious scarcity of fresh water (Williamson‚ 2010). Saudi Arabia is one of the driest countries in the world (CIA‚ 2011). According to World Bank (2011)‚ the world average fresh water consumption is nearly 7000m³/year/person‚ while the water resource per capita

A healthy eating plan incorporates healthy foods from a wide variety of food groups. The new food pyramid puts greater emphasis on consuming a wide range of foods‚ though still subscribes to the myth that fats are bad for you. So to answer the question‚ Why is Nutrition Important‚ we must understand how it relates to our health. Your immune system can be either bolstered

“WATER IS A GOOD SOLVENT” Water is very unique in all facets of its nature. The chemical formula for water is H2O as a water molecule consists of two atoms of the chemical element hydrogen (H) and one atom of the element oxygen (O). Water is the most abundant chemical compound on earth as its mass all exists together‚ naturally‚ in its gaseous‚ liquid and solid state. It is the most precious natural resource to man and is essential to life for all discovered living organisms. One of the unusual

Most water pollutants are eventually carried by rivers into the oceans. In some areas of the world the influence can be traced hundred miles from the mouth by studies using hydrology transport models. Advanced computer models such as SWMM or the DSSAM Model have been used in many locations worldwide to examine the fate of pollutants in aquatic systems. Indicator filter feeding species such as copepods have also been used to study pollutant fates in the New York Bight‚ for example. The highest toxin

of sucrose in the dialysis bag emerged in distilled water and the potato cores emerged in concentrations of sucrose. The data reinforces the principles of Osmosis and Diffusion‚ and in a biological context‚ we can simulate how water and particles move in and out of our own cells. Introduction Objective: 1. Investigate the process of osmosis and diffusion in a model of a membrane system. 2. Investigate the effect of solute concentration on water potential as it relates to living plant tissue.

Water Aerobics Water aerobics has been a strong growing type of exercise for many age groups for years. Water aerobics is a combination of arm and leg movements done in water for beginners. This type of aerobic exercise is typically done for less than an hour. This includes the same type of program as land aerobics with warm up and cool down periods. Swimming exercise uses more of the overall muscle mass of the body than almost any other form of exercise. (Water aerobics‚ "What is water aerobics"
