point and leaves by another. The severity of the shock is determined by three main factors: The amount of current flowing through the body; The path of the current through the body. The great majority of electric shocks enter through the arm and exit through the legs. As a result the current passes through the chest and affects the organs within; and The length of time the current passes through the body. Other factors that may affect

Steps in recognizing genuine BSP banknotes Version 1 and 2 1. Paper - the genuine note is printed on a special kind of paper which is rough when we run our fingers through it. 2. Watermark - is the shadow of the portrait appearing on the face of the note. 3. Security fibers - embedded red and blue visible fibers are scattered at random on both surfaces of the note. 4. Embedded security thread - special thread vertically implanted off center of the face of the note. It can easily be seen when

Invasive Species Threatens the Ecosystem Every life form all over the world depends on the ecosystem for its survival. However‚ the ecosystem can be threatened when there is an excess or drop in resources. Many people will argue that human beings are the primary cause of this economic imbalance‚ but are people the root of this problem? No. There is evidence that many invasive species all over the world has also threatened the ecosystem. All organisms have the potential to become invasive

Of all the species that have existed on Earth 99 percent have gone extinct and even fewer make it into the fossil record and a very small fraction of those that fossilize are actually found even partially complete. Even if all of them did fossilize many would be too hard dig for many of them. And also it is highly unlikely that most would be found complete‚ due to the number of natural disasters and processes that have happened from the animal’s death to whenever it is discovered. Natural disasters

NAME: DATE: LIMITS OF READING (LOR) MEASUREMENTS In science‚ the results of experiments are never 100% reliable. There are always experimental errors involved. It is therefore important to be able to assess the magnitude of these and their effect on the reliability of the final result. It is important to differentiate between the accuracy and the precision of a result. The accuracy of a measurement refers to the "closeness" of a numerical value to the actual or theoretical value. The accuracy

However‚ the price of steel is fluctuating these two years‚ which undoubtedly brings some unfavorable factors to the machinery industry including mobile concrete batching plant. The profits of the mechinery industry are gradually shrinking. How the mechinery industry extricate from such difficult situation and how can the machinery industry meet the present situation? Each concrete batching plant manufacturer should broaden sources of income and reduce expenditure and make full use of each sum of

Amylase enzyme‚ just like any other enzyme‚ has an optimum PH and temperature range in which it is most active‚ and in which the substrate binds most easily. The purpose of this experiment was to determine (1) the reaction rate of an amylase enzyme in starch and (2) the environmental factors that can affect the enzymatic activity. The hypothesis‚ in relation to the enzymatic activity by variables such as the substrate concentrations‚ temperature‚ PH and chemical interactions on the rate of

Shannon Angus Mrs. Cumbee January 9‚ 2013 Foreign Invaders Invasive species are groups of organisms that are unnaturally occurring to an area. When introduced‚ they can cause economic and physical harm to humans and ecosystems. The importing‚ legally and illegally‚ of invasive species into our society is not only harmful to our population and our ecosystem but also the population of plants and animals in their indigenous homeland. To continue‚ the smuggling of plants and animals into new

HPV: Environmental co-factors and prevention in the United States Introduction Current uses of medical technologies to prevent Cervical Cancer (CC) have proven inadequate in the further reduction of morbidity. Current medical methods are effective enough to almost completely prevent mortality from CC‚ but due to the inability of the US Health Care System to implement preventative measures in a timely and thorough manner‚ an estimated 10‚400 woman will be diagnosed with CC and more than 4‚000
