While cell membranes‚ heredity‚ gene expression‚ evolution‚ cellular metabolism‚ and chemical reactions are all appealing‚ water is undeniably more relevant. I decided to dissect the article entitled‚ “Water: The Science of Nature’s Most Important Nutrient” In this article Len Kravitz Ph.D. discusses the importance of water for human survival. The article does an excellent job of revealing

70% water and 30% of land. Our body is also composed of 2/3 of water. In other words life without water is INPOSIBLE.Imagine what would happen if amount of water in nature would be drastically reduced? I believe we all know the answer and the consequences. The entire flora‚ fauna and the entire human being will die slowly. Now a day‚ we have a lot of amount of water in our planet but that is a big paradox because a big part from that water is polluted. Basically living the life without water or with

Introduction Water is one of our most important natural resources. Water is used in different purpose such as domestic‚ industrial supply‚ transportation‚ recreation. However‚ nowadays‚ humans are continuously deteriorating rivers‚ lakes‚ and oceans through different agricultural‚ industrial activities. Abel (1996) states that water pollution defines as “the addition of undesirable materials into aquatic bodies” (p.1). This may cause physical‚ chemical or biological change in water‚ leading to different

Water waste management is the field of handling waste water to make it suitable to either be recycled into a water system or to be disposed of in an environmentally-conscious manner. This is one of the larger problems facing most major cities in the modern world‚ with overflow causing severe pollution problems and increasing population densities stretching existing infrastructure to the breaking point. Both mechanical and biological processes are used to manage wastewater to get rid of undesirable

Water Pollution All around the world‚ countries are fighting to keep their water clean. Whether it’s streams‚ rivers‚ lakes‚ or the ocean‚ countries have taken great measures to maintain a high quality of water for both human consumption and as a key component to the environment. We deal with the pollution problems and then decide on ways to clean it up. This valuable resource is the key to survival. Both plants and animals depend on water for their growth‚ so the water must be kept clean

Aim: To compare the foaming capacities of five different commercial soaps. Apparatus: 5 test tubes‚ 5 conical flasks (100 ml)‚ test tube stand‚ Bunsen burner and stop watch. Materials Required: 5 different samples of soap and distilled water Theory: The foaming capacity of a soap sample depends upon the nature of soap and its concentration. This can be compared for various samples of soaps by taking the same concentration of solution and shaking them.The foam is formed and the time taken

During muscular exercise‚ blood vessels in the muscles dilate and blood flow is increased in order to increase the available oxygen supply‚ to allow the muscles required to function properly. Up to a point‚ the available oxygen is sufficient to meet the energy needs of the body. However‚ when muscular exertion is very great‚ oxygen cannot be supplied to muscle fibres fast enough‚ and the aerobic breakdown of pyruvic acid cannot produce all the ATP required for further muscle contraction.
