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

Industrial growth is directly related to nation’s economy. Construction of major and minor irrigation projects and development of new power plants must not be frozen. Hence at the present context‚ when man has reached at twenty first century‚ no body would want for technological stagnation. On the other hand‚ excessive exploitation of the environment through these technological implications leads to disaster. Hence‚ there is the problem of one word "pollution." So what is needed is the environmental

pressure on arable land contributes to the land degradation. The increasing population numbers and growing affluence have already resulted in rapid growth of energy production and consumption in India. The environmental effects like ground water and surface water contamination; air pollution and global warming are of growing concern owing to increasing consumption levels. The paper concludes with some policy reflections‚ the policy aimed at overall development should certainly include efforts to control

Water Scarcity & the Importance of Water Introduction: This report has been written to inform you of the world water crisis which is getting worse every second. It has also been written to inform you about the water scarcity and importance. Water Scarcity and importance: Clean‚ safe drinking water is not easy to find any longer. Today‚ nearly 1 billion people in the developing world don’t have access to it. Yet‚ we take it for granted‚ we waste it‚ and we even pay too much to drink it from little

Water pollution is the contamination of water bodies (e.g. lakes‚ rivers‚ oceans and groundwater). Water pollution affects plants and organisms living in these bodies of water; and‚ in almost all cases the effect is damaging not only to individual species and populations‚ but also to the natural biological communities. Water pollution occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds. Contents [hide] • 1 Introduction

BIOCHEMICAL IMPORTANCE OF WATER Of all the simple chemicals that are found in abundance on Earth‚ only water is liquid under normal pressure and temperature. When life first appeared on planet Earth‚ water has played an important role in creating the first organic compounds. The organic compounds later‚ formed the first prokaryotic organisms. Life began‚ as the modern theories support‚ in water and developed for three billion years in it before spreading on land. It is no coincidence that the

Biological Importance of Water for Living Organisms Water is made up of two elements‚ 2 positively charged hydrogen molecules and one negatively charged oxygen molecule. Water molecules have uneven charge distribution as one end of the molecule is slightly positive and the other slightly negative‚ this is called polar. Ionic substances such as sodium chloride dissolve easily in water because the positively and negatively charged ions are separated due to the dipole nature of water. As water is dipolar
