water is the most important substance in our evolution and our daily lives. This essay will examine the water molecule in order to ascertain how it brought about earth's successful ecosystem and how important it is to us today. Richerson amp amp robert boyd human language has no close parallels in other systems of animal communication. Yet it is an important part of the cultural adaptation that serves to make humans an exceedingly successful species. Water makes up more than two thirds of the weight of the human body, and without it, we would die in a few days. There are many water importances in our life to complete daily life and to maintain we body health.

Dehydration is defined as a loss or insufficient levels of water and important blood salts like potassium and sodium in your body. Important organs like the kidneys, brain, and heart cannot function properly without water and salt. Signs of dehydration include fuzzy short term memory, trouble with basic math, and difficulty focusing on computer screen will occur if less water in the body.

Water also importance in homeostasis process to maintain the relatively constant temperatures within the body. This is important because it means that sudden changes in the temperature, which may upset metabolic reactions in cells, are avoided. These chemical reactions are allowed to take place within a narrow temperature range so that rates of reaction are more constant.

This means many compounds, whether ionic, polar or covalent will dissolve in it, therefore more reactions take place while in solution with water. Human digestion will only dissolve soluble foods, meaning large starch molecules must be broken down into soluble sugars. Also many organisms living in water spend most of their time underwater, yet they require oxygen to respire, and as water is such a good solvent the required oxygen gas is dissolved in the water. It's important to understand and examine the water molecule in order to ascertain how it brought about earth's thriving ecosystem and how important it is for us today. Water is a strong solvent, it's a very unique molecule that can breaks and reforms constantly. The oxygen atom also called the apex of the water molecule bears a slight electronegative charge while hydrogen possesses a more positive one kirk 225. When an oxygen atom is linked to a molecule's hydrogen atom, a bond called a hydrogen bond is formed kirk 256.

There are several types of water molecule such as liquid water, ice and water vapor. In a liquid form of water it has no such spaces because hydrogen bonds constantly breaks and reforms. Thus ice is stable hydrogen bonds that bonded together, it's less dense and will float on liquid water. If it's not this reason, the great bodies of water would freeze from the bottom up without the insulation of a top layer of ice, and all life in the water would all die bio notes water is a very small molecule that has its own unique properties therefore it behaves like a larger one. The bonds between water molecules are the covalent bonds these bonds are so strong that water resists changes in its state. Thus water has a higher melting point and a higher boiling point than any other molecule of similar size kirk 256. When heat is applied to solid water, some hydrogen bonds get so much kinetic energy that they break and the ice melts.

Of the total surface of the earth, 75 % is water and just below the surface of the land in most areas there is a saturated layer known as the water table. Animals and plants have large percentages of water in their make up and some animals regulate their movements according to the water sources.

Scientists find water the most fascinating fluid in the world because of its versatility and usefulness.
