Day-To-Day Mechanisms: The Biological Properties Of Water

As a result of the water molecule bond, each (hydrogen; oxygen) has a slightly negative charge and each (hydrogen; oxygen) has a slightly positive charge.

Comprising over seventy percent of the Earth's surface, water is undeniably the most valuable natural resource. Life on Earth would be non-existent without water because it is essential for everything on our planet to grow. The human body is composed of 50-80% water. Blood and muscles contain significant amounts, and approximately 95% of the brain is water. All body systems and organs need water to function properly, and will shut down without it. Most of the chemical reactions that take place in our body need water as their medium. We can live without food for a few weeks, but can survive only a few days without water. It's essential because unlike other nutrients, water isn't stored in the body. Typically, everyday, we lose around 10

The Importance Of Water To Living Organisms Water is normally the most abundant component of any living organism. As most human cells are approximately 80% water and 60% of the human body is made up of it, it is extremely important in many different ways to both the survival and the well being of living organisms. Evolutionists believe that life probably originated in water and even today thousands of organisms make their home in it. Water also provides the medium in which all biochemical reactions take place. The importance of water to living organisms originates from its many properties including its solvent properties, its high specific heat capacity, its high latent heat of vaporization,

Water is the most important substance on earth, all plants, animals and humans must have water to survive.

Water is a very important component of life, our bodies are mostly comprised of water and water covers over 70 percent of the earth’s surface. Water is important for the sustainment of life, every organisms depends on some type of water source. Plants, animals, and insects can not survive absent of water wether it is a couple of days or a couple of months. Water is a special element of life because of its chemical bonds, the chemical formula for water is H2O, which means that water contains two hydrogen atoms and one oxygen atom. These atoms are held together by hydrogen bonds, the hydrogen bonds. The strong cohesive bond of the atoms in water are important, this makes water molecules much stronger than many other liquids. Water also

A World without Water: Imagine on earth without water, life without water we find it every way; in the atmosphere and below our feet three quarters of the earth’s surface is covered by this essential liquid. It’s a difficult thing to imagine in life without water, because our own survival depends on it; in fact water is vital to the existence of all forms of life on earth. Water or H2O, is an unusual compound with amazing properties, these unique properties are what make it so important to life. All living organisms that use fresh water will die. Because of the availability and quality of water have always played an important part in determining where people can live and also their quality of life. Life revolves around water. Water IS life.

to form a weak hydrogen bond. The bonds are weak but a large number of

Generally, water is understood as a neutral and transparent fluid which is found in streams, rivers, lakes and oceans from all over the world, not to mention that rain a collective source of water. Venturing in chemistry, water is a chemical compound whose formula is H2O. It composed of two elements; one oxygen element and two hydrogen element which are chemically bonded together (Mobley, 1994). Apparently, water makes the highest percentage of fluids in the bodies of living organism. As a matter of fact, there are states in which water can be available depending on temperature, and they are ice as solid water, steam as water in gaseous state and liquid water at standard temperature and pressure (Mobley, 1994). These three states are well known to co-exist on earth, having other inconsequential forms like cloud, fog and dew. Most importantly, water is known to cover 71% of the total earth’s surface, a worthy reason as to why it is very vital for all life forms (Vörösmarty, Green, & Lammers, 2000). Water distribution on earth is as follows: 1.7% is found in underground water, 1.7% in glaciers as well as ice caps, 0.001% in the atmosphere and the largest percentage being 96.5% in oceans and seas (Vörösmarty, Green, & Lammers, 2000).

Water is an essential component for human development for its ability to keep the body hydrated and conduct complex physiological process to ensure for a healthy wellbeing. In addition, water is vital as it composes 75% of the human body. Several other features water is beneficial for humans is that it assists in transporting nutrients and waste products into and out of the cell, distribute and dissolve oxygen and carbon dioxide present in the lymphatic and haemolytic system to the surrounding tissue, monitor salt and mineral concentrations, and maintain a balanced body temperature. A significant loss of water from the body can result in death, thus with no doubt water is absolutely essential to life. However two fifths of the world’s population do not have access to clean and sanitary drinking water (World Health Organization, 2000). Worldwide, there is less than 1% clean and accessible drinking water and majority of the fresh water is in North America. It is a human right to have access to safe and sanitary drinking water to ensure long-term health, but millions of people are threatened of the risk factors associated with unsanitary water and catch diseases due to biological and chemical contamination.

Water is a one of the most useful substances found on Earth. In fact, the bonds between two hydrogen atoms and one oxygen atom turned out to be an essential component in shaping our world. This amazing material is crucial to the survival of many living things, including plants. Plants are autotrophs, meaning they make their own food using energy within their environment. In order to make food, plants need carbon dioxide, sunlight, and water (Starr, Taggart, Evers, & Starr, 2016). This means that water is essential photosynthesis, the process by which plants make their food, making water an instrumental part of plant growth. Therefore, if plant growth is related to the type of water used, then plants growing with different

Water covers about 70% of Earth’s surface, makes up about 70% of your mass, and is essential for life. Of the three essential requirements of human life, air, water and food, water plays a most important role to maintain the tissues of the body in healthy functioning. Without an ample supply of potable water, all the functions suffer as the body degenerates, and also air cannot clean the bold sufficiently and food is imperfectly assimilated. 66 % of the human body is water; 75 % of the human brain is water. Man is over 60 % water by weight, constituting 26.5 liters inside the cells and 3.5 liters in blood. The continuous working of human body is a function of constant rotation of release and replacement of water, at any stage disturbance in the cycle will result to damage various tissues. However if supply is impure it dangers the lives of consumers and may also create water-borne diseases.
