The Biological Significance Of The Properties Of Water Essay

Water is a medium for metabolic reactions and an important constituent of cells. In most plants and animals, it makes up about 65-95% of their mass. The water molecule is referred to as a dipole, a polar molecule, with a positive (hydrogen) and negative (oxygen) charge, separated by a very small distance. A molecule with a separated charge is polar. A hydrogen bond; the weak attractive force between a hydrogen atom with a partial positive (o+) charge and an atom with a partial negative charge (o-) oxygen can be formed between two atoms. Hydrogen bonds are weak, however in large quantities, like the large number present in water it makes the molecules difficult to separate and gives water a wide range of physical properties vital to life.

Living things are mostly made of water because it possesses important elements that are necessary to sustain life in addition to refreshment and nourishment. For example, cells are made of 70-95% water and are surrounded by water as well. Water also helps fluidity in the body, with nearly 54% water in our blood. Our bodies are made of 75% water, making many functions such as the transportation of hormones, chemical messengers, and nutrients to vital organs dependent on water. In addition to human bodies, plants are also made out of water. Water is necessary to plant life because it helps with the germination of seeds, photosynthesis, the transportation of minerals and nutrients from soil to plants, and the structure of the plant to thrive and survive.

The human body consists mostly of water, and is a major constituent to the human body and vital organs; of this 90% include blood plasma, lymph, urine, saliva, digestive juices, bile, cerebrospinal fluid and tissue fluid. Water enables substances to be transported throughout the body, red blood cells for example, as wells as supplying the medium required for metabolic reaction to take place (respiration). Without water the progression of these fluids would not be possible. Water is constantly being transported between the fluid compartments of

(Click Slide) Another unique property of water is its high specific heat capacity. Due to the strong hydrogen bonds that exist between water molecules, a lot of energy is needed to break down the bonds. As the Particle Theory states, particles move faster and further apart when heated. This is why water helps maintains a moderate temperature on Earth and different bodies of water, crucial for the survival of organisms.

Water: a necessary facet to all living things. For animals, water can be a home or a drink. As for humans, the uses of water are endless. Not only do we use water as a beverage or washing clothes or dishes, but we also use water for toilets, various kinds of plumbing and other things that aren’t as easily identifiable. As of 2005, this 70% of our Earth has been manipulated and used for thermoelectric power (41.5%), irrigation (37%), domestic affairs (8.5%), public supply (5.4%), industry (5%) and aquaculture (2.6%).1 The importance of water is infinite, not only to our way of life, but also our lives. We need to drink water to ensure the health of individual cells of the body, lubricate joints, moisten mucous membranes of the organs and many other vital bodily functions.2 Not only do we expect the availability of water, but it is highly important to humans and all living things. Although it is such an integral part of our Earth, one may ask about some of its properties and characteristics.

In water, Hydrogen bonding pulls molecules close together by the negative oxygen made by another molecule of water is attracted to a positive hydrogen atom. Thanks to hydrogen bonds, water boils at 212 degrees Fahrenheit instead of -108.4 degrees. Hydrogen bonds are also make up proteins and DNA (wisegeek). Covalent bonds are bonds between two non-metals that share electrons with one another. Covalent bonds occur when they have similar electronegativity (diffen). An Ionic bond is where a metal and a non-metal bond when the metal gives up electrons to complete the outer shell of a non-metal, and then an attracting another with the now polarized atoms (differencebetweenExplain the 7 characteristics of life.In order for something to be considered a living being, they need to follow a set of seven rules. The first is that living things are made of cells, either single celled or multicellular. The next rule says that a living thing must have both molecular and cellular organization on several levels. Multicellular beings must have tissue, organs, and organ systems to be considered an organism. Livings must use energy for maintenance and growth; Energy can come from other

Water constitutes 50% to 70% of the human body. Its unique chemical properties enable it to dissolve substances as well as serve as medium for chemical reactions, temperature regulation and lubrication (found in the knees and other joints of the body); it also aids in regulating the acid base balance in the body. It helps remove waste from the body and is the basis for saliva, bile and amniotic fluid.

Throughout the article, the author talks about how the properties of water can be related to square dancing. The molecules of water take the place of the dancers as they move coordinately. Water does not conform to the same properties of other liquids. Water has many different properties that are talked about in the article. The most famous and most talked about property in the article is water’s density at low temperatures; like how it expands as it cools. Other liquids condense as they get cooler but water does the opposite. At super cooled temperatures, the properties of water become stranger as it is able to exist as a liquid much below its freezing point. Another strange property of water is that in super cooled states, it splits into two

Is water a reason we’ve evolved so much? Water consists of oxygen and hydrogen and is an essential to life. Water is what keeps our crops growing, which also keeps us alive. But has it affected our past and present. It's in many ways, like why we drink water instead of drinking other drinks, like Gatorade, or how in the past and present we have tried to evolve our way of how to transport water, and how we used to believe in gods and goddesses about water.

It is no secret that criminals are always in search of means to effectively destroy any evidence that may implicate them in a crime, particular involving friction ridge skin as it is often speculated to be the most damning form of of evidence that exists. This is due to the undeniable uniqueness of fingerprints that remain unchanged throughout a person’s lifetime (Holder, Robinson & Laub, 2011). Over time efforts to destroy friction ridge skin evidence have included methods of water to wash away the latent print evidence, not a shocking concept once we think about how vast bodies of water occupy over 70% of the earth’s surface (Williams, 2014). Therefore, as a means to examine the effects of water submersion on latent fingerprints, an experiment was conducted to identify the impact four variants of water solutions have on latent fingerprints.

A molecule of water is made up of two hydrogen atoms that are covalently bonded to a single oxygen atom at an angle or 104.5°. Due to its intermolecular forces, water is classified as polar and is known as the “universal solvent” and is able to dissolve other polar substances and acts as the solvent for several chemicals which are part of important chemical processes. Water’s unique structure also allows it to be less dense in its solid state which allows many aquatic organisms living within the water to survive in the liquid water beneath the solid ice. Water also has strong surface tension and a high melting and boiling point which allows water to exist in exceptionally hot climates as well. One important function maintained by water is waste removal which helps a cell to function more efficiently. In additional to waste removal, water also transports many important nutrients to cells and is key in maintaining homeostasis by regulating conditions in order to retain stability within a cell. Without water many vital processes wouldn’t be able to occur, and without water humans can live no longer than 3 to 5

5.2.7 Explain why water’s ability to absorb heat is important to aquatic organisms and to life on earth generally.

Our body, living cells, are made up of 50 to 80% of water. It has the properties of maintaining homeostasis in temperature by increasing the heat through absorption & release of heat, causes us to sweat when our body temperature is too high, acts as a major solvent in our body, has a reaction in hydrolysis, and acts as a cushion keeping organs protected from any physical harm.

As seen in the polar bonds diagram, the electrons have a negative charge, therefore, the unequal sharing in the H-O-H bond results in oxygen acquiring a partial negative charge and hydrogen a partial positive charge. The charge differences cause the water molecules to attract each other and other polar molecules. (Worldofmolecules.com, 2014). This attraction is called hydrogen bonding. A lot of
