lagao toh dar jayegi‚ Upar laoge toh mar jayegi Meaning: Fish is the queen of water‚ whose life is water; It is scared of the touch and out of water it shall perish This is not just true for fish‚ but for any life on the earth. The biosphere with its fauna and flora owes its existence to water. In the solar system it is only our earth that is credited with water‚ that too just 1% of the entire water‚ that is potable. It is therefore a gift and a coincidence‚ too. Man has therefore a

’ Water! Water! Water! ’: These are the words of a person dying from thirst‚ which me or you might be hearing or even crying it out aloud in the near future‚ because human being’s most serious problem and dilemma in the 21st century might not be war or hunger or disease or the collapse of civic order‚ it may be the lack of Fresh Water‚ according to a United Nation’s (UNESCO) report. At present 1.1 billion people lack access to clean water‚ while 2.4 billion lack access to proper sanitation‚ nearly

BOTTLED WATER – A REPORT 1. INTRODUCTION: The global bottled water industry has become very profitable in the past ten years. Huge multinational companies currently make billions of dollars on water they simply extract from the ground‚ slap a label on and sell at competitive prices. Examples of these companies includes: Aquafina (Pepsi)‚ Dasani (Coke)‚ Perrier (Nestle)‚ Evian‚ and Fiji Water among hundreds of others. Many countries have become very oriented toward bottled water. According to

Water Shortage Water shortage problem is when humans or living creatures suffer from a scarcity of water another definition for water shortage is either the lack of enough water or lack of access to safe water and it happens because of the dreadful use of water and polluting rivers‚ oceans and lakes. Water is the reason for our existence; Water everywhere on the planet is a basic part of the global hydrologic cycle‚ it ’s a finite resource. The amount of water supply in the global hydrologic

An Introduction to Water Analysis February 1 and February 8 2011 Aim and Objective: The aim of this experiment was to determine the pH level of an unknown HCl solution. While doing so‚ we would also be receiving a good and fundamental understanding of how to use modern lab equipment to determine the chemical and physical properties of water bodies. Method: Make sure safety gear is always on and equipment is always clean. Part 1- Direct Analysis by pH Test Kit We grab a 50ml beaker

Natural Benefits of Drinking Beet Juice: Drinking beet juice can lower blood pressure levels in just a few hours. One study found that drinking one glass of beet juice lowered participants’ blood pressure by an average of 4-5 points. This can be attributed to the naturally occurring nitrates in beets‚ which are converted to nitric oxide in the body. This then relaxes and dilates the blood vessels to improve blood flow and lower blood pressure. Many illnesses and chronic diseases begin with inflammation

For example‚ "The cell membrane is the barrier which separates the inside of the cell from the outside." Use future tense for work that you will do. For example‚ "This experiment will test the hypothesis that some anti-microbial agents can permeate the cell membrane during division to inhibit growth." Use past tense to describe the methods (what

Properties of Water Lab # 1 Biology 111 January 23‚ 2011 INTRODUCTION With surface tension it is made possible for items such as paper clips to float on water‚ because a molecule within the mass of a liquid encounters gravity to all adjacent molecules in all directions. When you use surfactant substances this creates hydrogen bonds. Purpose of experiment 1 will be to show that once the surfactant substances hits the hydrogen bond pulls down paper clips. Things
