Next to water and air‚ soil is most essential to our very existence on the earth. Soils are the basis of support for most life‚ and a source of nutrients for marine life and fresh water. As a natural resource‚ soil is of immense value to man. In the agricultural orient the distribution and density of population have conformed to the persisting patterns of soil fertility and productivity. Soil is basically broken-down rock materials and consists of decomposed rock debris and decayed organic

In a synthesis equation there will always be two or more reactants‚ but only one product. The geneal formula for a synthesis reaction is: A+BAB. An example of this would be Lithium+Oxygen Lithum Oxide. Decomposition is defined as to separate or breakdown into smaller pieces. During a decomposition reaction‚ one substance breaks down into two or more substances. It is a synthesis reaction in reverse. The general formula for this is: ABA+B. An example of this is wateroxygen+hydrogen. Single deplacement

CROP PRODUCTION AND MANAGEMENT Types of Crops Soil Preparation Sowing Harvesting Fertilisers Insecticides All living organisms require food. Plants can make their food themselves. Animals including humans can not make their own food. The energy from food is utilized by organisms for carrying out their various body functions‚ such as digestion‚ respiration and excretion. We get our food from plants‚ or animals‚ or both. In order to provide food for a large population— regular

Sugars are vital to all living organisms. The eukaryotic fungi‚ yeast‚ have the ability to use some‚ but not all sugars as a food source by metabolizing sugar in two ways‚ aerobically‚ with the aid of oxygen‚ or anaerobically‚ without oxygen. The decomposition reaction that takes place when yeast breaks down the hydrocarbon molecules is called cell respiration. As the aerobic respiration breaks down glucose to form viable ATP‚ oxygen gas is consumed and carbon dioxide is produced. This lab focuses on

Braxton 1 Denielle Braxton Rameau AP English III 29 Jan 2015 Art‚ since the very beginning‚ exists as an outlet of emotional and physical feelings for our species ever since cavemen learned to draw on walls. Poets‚ authors‚ singers‚ and every form of artist have been portraying the emotions through canvases and words that a meager simple minded person cannot begin to express through his vocabulary. Whether a screenwriter describing a scene of love at first sight or a painter using his mixture of

Chemistry is the science of dealing with the compounds‚ elements‚ and molecular structure of matter. Essentially‚ chemistry is the science of examining substances and objects to find out what they’re made of and how the react to different conditions.

Proceed now to Exercise 2D: An Enzyme-Catalyzed Rate of H2O2 Decomposition. In this experiment‚ we determined the rate at which a 1.5% H2O2 solution decomposes when catalyzed by the purified catalase extract. To do this‚ we determined how much H2O2 had been consumed after 10‚ 30‚ 60‚ 90‚ 120‚ and 180
