Why Is Water Unique

Water is one of the best and one of the most important too tall of the biological systems. Water doesn’t not only exist in the 3 states of matter which are, solid liquid or gas. Water covers just about 75 percent of the earth and is throughout 78 percent of the human body. Without water there are any things that we would not be able to do. We would not be able to travel from place to place to go on cruises and we would no longer be a beach or water to drink. We would no longer be able to shower or go to the pool or be able to have any use of water and many animals would no longer exist. Without water the human body would only be able to last only three days. The reason that water is so unique is because of its molecular structure. Due to the fact that it is a polar covalent molecule it has very little positive and even smaller chances of a negative charge on opposite ends. Also because is called “a bent” which is basically a polar molecule, it contains a real important characteristic of what is built and formed when lots of water molecules. Molecules join or fuse in which all of them are critical to the creation and support of life on earth. One …show more content…
The DNA in our cells is double stranded � there are two strings of nucleotides that are joined primarily by hydrogen bonds between the strands. We mentioned earlier that hydrogen bonds, when considered as individual bonds, are very weak. However, when we consider hundreds of hydrogen bonds together, a relatively strong and stable structure can result. Nucleotides from one strand make two or three hydrogen bonds with complimentary nucleotides of the other strand, depending on the nucleotide pair. The two strands together make up the helical DNA molecules that transfer genetic information from one generation to the next. Without these molecules, life would have a very difficult time perpetuating itself on the
