The Biological Importance of Water! The ultimate importance of water is none other than the fact that life cannot exist without it. Water being the major component of our body cells‚ typically making 70-95% of it‚ constructs the body mass with approximately 80% being water. Humans are not the only ones who contain the valued material but other creatures like the jellyfish hold 96% of water as their body mass. The structure of the water molecules enables it to have extreme properties that are

Properties of Water Lab # 1 Biology 111 January 23‚ 2011 INTRODUCTION With surface tension it is made possible for items such as paper clips to float on water‚ because a molecule within the mass of a liquid encounters gravity to all adjacent molecules in all directions. When you use surfactant substances this creates hydrogen bonds. Purpose of experiment 1 will be to show that once the surfactant substances hits the hydrogen bond pulls down paper clips. Things

Uses of water: 1. For drinking and for life processes. On an average‚ a man consumes about 60‚000 to 80‚000 litres of water in his lifetime. The body of an adult contains nearly 40 to 50 litres of water at any given time and water constitutes about 66% of the average body make up. Aqueous solutions fill the cells in the body. Nutrients‚ oxygen‚ and metabolic waste products are transported by blood‚ which is mostly water. Digested food is absorbed in the form of an aqueous solution. In plants too

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. If there is no water there can be no life.

as salt because it does a great job melting ice‚ but it also damages concrete surfaces over time. How does salt damage concrete surfaces? Salt lowers the pH balance in the concrete. Because it is acidic‚ it weakens the strength of the concrete and increases the sizes of the pores. This allows water and other elements to penetrate the surface. Salt also attracts and retains water‚ absorbing 10% more water into the concrete. When the water freezes in the concrete‚ the pressure of frozen water increases

WATER Conservation INTRODUCTION: Water is essential for life on earth. Water is needed for growing food‚ keeping ourselves clean‚ generating power‚ controlling fire and most importantly to stay alive! This list is simply non-ending. This shows that water is an integral part of our daily life and we are heavily dependent on it. Water conservation: Refers to reducing the usage of water and recycling of waste water for different purposes such as cleaning‚ manufacturing‚ and agricultural irrigation
