the biological importance of water Water‚ the most abundant compound on the planet‚ is a material which is essential for all living organisms. Its uses in all living things cover a huge variety of everyday functions which are immeasurably important to the continuity of the organism. The fact that water makes up between 60 and 95 percent of all living organisms speaks for itself on the incredible biological importance of this compound. One of the major functions of water in living organism is

Human body needs three requisites for its smooth functioning – oxygen‚water and food in that order.Our first requirement to live is oxygen since we cannot survuvive more than a few minutes without taking oxygen.Water has been ranked as second only to oxygen as essential for life because we can stay for a few days without drinking water.Then comes the food. Human body is made up of two-thirds of water and one-third of solid matter.The average adult body is 55 to 75% water. A human embryo is more

The importance of water: Water is the most wanted or used resource in the entire world‚ due to its demand. It is wanted and needed by everyone for various reasons‚ some of these reasons are for everyday things like drinking in order to suvive‚ cooking cleaning‚ technology and even basic things like gardning. It also helps with poverty ‚ health‚ hunger and education. Water is a blessing. If we did not have water neither of us will be here‚ so why are we thanking it by missusing or wasting it for

how hydrogen bonding occurs between water molecules‚ and relate this and other properties of water‚ to the roles of water in living organisms. Water is a very small molecule‚ consisting of two hydrogen atoms covalently bonded to an oxygen atom. However the electrons shared are not done so equally‚ oxygen is more electronegative and has a firmer hold on the electrons and pulls them slightly towards its nucleus. Due to this‚ the charge across the molecule of water is not equally distributed‚ and the

explored who‚ if anyone‚ would be responsible for meeting the wants of the human population. Currently‚ water is a crucial natural resource for people everywhere. However‚ our water supply is decreasing due to many factors. In exploring this dilemma module 5 raises questions such as Who will be entitled to water when supplies become scarce? In the text‚ Facing the Fresh Water Crisis‚ Rodgers claimed that the exponential water consumption will eventually degrade all ecosystems on Earth. In response
