not exist without water. Seventy-five % of the Earth is covered in water providing an environment for organisms to live in. the water molecule is made up of two hydrogen atoms and one oxygen atom. As oxygen atoms are more electronegative that hydrogen atoms the electrons shared covalently between the oxygen and the hydrogen atoms tend to spend more time near the oxygen atom making it partially negative and making the hydrogen atoms partially positive. The partial charges in the water molecule allow

The biochemical importance of water Sam Ellick 13/11/2010 Water otherwise known as H2O is a necessity for life to exist. It has many unique features compared to other molecules of its size. For example solid ice is less dense than liquid ice‚ which ponds and lakes freeze from the top down. This is important in insulating the aquatic life in the winter. This essay however will be looking at why water is so important in biochemical terms. Its shape Water‚ as its formula H2O suggests‚ consists

IMPORTANCE OF FRESH WATER All living things on Earth need fresh water in order to survive But human beings become ill and may even die if they cannot get pure or clean and are forced to drink polluted water. Human beings can only last 3 day without fresh water. People died of thirst after the cyclone in 1999 because their supply of fresh water from irrigation channels was destroyed form tidal waves. However water is needed for many more purposes e.g. in agriculture and industries‚ but this water

The Importance of Water The water that we consume today is the same water since pre historical period .The importance of water has not changed; the only difference now is the purity and efficiency of it. Barbara Kingsolver‚ a famous American writer‚ explains the problems concerning water in her article‚ “Fresh Water.” Humans’ inclinations to excessively use natural assets have caused climate change and drought in many parts of the world‚ making it difficult for many people to access clean and fresh

The topography abounds with large stones which have been utilized to make larger than life statues of Hindu deities. A structure of historic importance appears every quarter of a mile.

The importance of water in Biological Systems Much of the Earths surface is comprised of water‚ as well as much of biological systems; for instance‚ the human body consists of approximately 70% of water‚ and in other biological organisms this figure could even be 95%. This largely relies on the bonding of water‚ whereby two hydrogen atoms bond to one oxygen atom; hydrogen bonding is the strongest intermolecular force due to its high polarity. Hence‚ what is the biological importance of water?

The Importance of Body Language in Tutoring “Body language is a very powerful tool. We had body language before we had speech‚ and apparently‚ 80% of what you understand in a conversation is read through the body‚ not the words.” (Deborah Bull) Body language plays‚ in my opinion‚ an important role in tutoring and it is especially important with ESL student who often use observation to understand better and to compensate some deficit in oral communication. According to Wikipedia’s definition

Water has importance inside cells and externally. This may be because it has interesting chemical and physical properties; it can be found naturally in all three of its states. However its molecules are bonded together by hydrogen bonds‚ this raises its melting and boiling points‚ i.e. its boiling point would be -120¢ªC rather than 100¢ªC. Also because it contains slightly negatively charged oxygen atoms and slightly positively charged hydrogen atoms making it polar. <br> <br>Water has been called
