This is important because humans‚ animals‚ and plants all need water to survive. It is controlled by the sun‚ which produces energy in the form of heat. This heat energy causes the water in the world ’s oceans‚ lakes‚ etc. to warm and evaporate. As the water is heated‚ it changes its phase from liquid to gas. This gas is called water vapor and this process is called

Effect of Soil pH on the Living Conditions In Lumbricus terrestris Abstract The difference in soil pH weighs a heavy measure on the appearance of the earthworm Lumbricus terrestris in different areas of soil. A highly acidic or highly alkaline soil may be the underlying reason for the absence of this earthworm in certain areas where pH plays a large role. In this experiment‚ soil pH was altered with Miracida soil acidifier and Agricultural Limestonea soil correctional for acidic soil. This was

Water Shortages Water has been one of our natural resources that we have used throughout time in many different ways. We have developed ways to make it more available and use it to create energy. However‚ because we have made it more available‚ we have developed issues that waste our good clean water‚ take old pipes that have been used to transport water across cities for example. Because they are so old‚ they tend to waste about 7 billion gallons of water every day (CQ Report‚ 2010‚ p.531). And

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
