Introduction Water plays a vital role in biological systems. Some species are able to survive in diverse environment such as fishes in salt water‚ Cactus plants in dry land and mammalian cells in aqueous surrounding because of the specialized underlying structures of these life-forms. In order for us to appreciate these special adaptation‚ we first need to know how a typical plant or an animal cell organelle behaves in different water and solute concentrations. In this lab‚ we will determine the

“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

Hydroelectricity and its Potential in Pakistan Muhammad Uzair Khan (2010-MC-07) Hassan Javaid (2010-MC-20) Syed Muhammad Talha Zaidi (2010-MC-54) What is Hydroelectric power? Renewable source of energy It is renewable because the process takes nothing away from the environment . Advantages 1. Flexibility 2. Low power costs The major advantage of hydroelectricity is elimination of the cost of fuel. No import of fossil fuel is required. The average cost of electricity

The Potential of Pericytes Found in Blood Vessels Do pericytes found in blood vessels create more potential for adult stem cell research? The capability to revert blindness‚ cure diabetes‚ let paralyzed people walk again‚ replace deficient organs with newly grown ones and cure blood diseases are a few of the many potential functions of stem cells. A stem cell is an unspecialized cell that can develop into many different cell types in the body during early life and growth

We have a fascination with bottled water. Somehow‚ somewhere‚ someone decided the tap water was not good enough for us‚ and along came the obsession that water in a bottle was better for us. Most of us would agree

colloquium “Charity Water‚” by Cubby Graham. In this colloquium‚ Graham talked about 800 million people who didn’t have access to clean‚ safe drinking water. Diseases such as e. Coli‚ Salmonella typhi‚ and schistosoma were found in the water that they were drinking from. They shared the same water with the animals as well. People were also battling with leaches stuck in their throat from drinking the water. Graham talked about this one little girl from India that kept vomiting the water she was drinking

drinking water samples from different places using four of the standard drinking water tests required by the EPA. The experiment will be performed by a four person group‚ with each person providing a different water sample. The four tests to be performed are: pH‚ conductivity‚ phenolphthalein and total alkalinity‚ and total and non-carbonate hardness. Data from these four tests will be gathered and analyzed‚ drawing conclusions “about the validity of the data as well as the quality of water” (Kippenhan

Hard Water How can water be hard? Well‚ it can‚ but maybe not in the sense that one would think. Hard water refers to water with dissolved calcium and magnesium ions in it. Rainwater is naturally soft‚ but when the water runs through the ground or over rocks causing erosion‚ calcium and magnesium ions can be easily picked up. Most people prefer hard water to soft water for drinking‚ because the ions are good for you‚ and because soft water leaves a “dry” taste in one’s mouth (1‚2). Big businesses

Brittany Bolling April‚ 28th 2011 Dr. Woolnough BIO 101 DO6A ABSTRACT: The objective of this study was to observe and understand what occurs in a sample of pond water over the course of six weeks. Over the six weeks there were qualitative and quantitative data found and recorded. The qualitative data recorded entailed: Water color and smell as well as suspended solids ranging from clear‚ opaque‚ and turbid. The quantitative data that was recorded regarded: Temperature‚ pH‚ Alkalinity‚ Hardness
