Abstract: This report presents the reason why the ocean does not freeze in the winter. Since the ocean consists of salt water‚ an experiment was done to test the effect of freezing on salt water compared to pure water. The experiment was conducted three times in order to obtain accurate results and eliminate errors. In addition to the salt and pure water experiment‚ a variation of this experiment was created to test other options. In the variation experiment the effect of freezing on sugar water

h e S a h a r a D e s e r t The Sahara Desert is the largest hot and dry desert in the world. It is located in North Africa; it covers 9 million square kilometres and covers over twelve countries‚ some of the countries include; Morocco‚ Algeria Libya‚ Tunisia‚ Egypt‚ Mauritania‚ Mali‚ Niger‚ Chad‚ and Sudan. Most of the Sahara Desert is located at Algeria. The Sahara Desert receives less than 40cm of rain per year‚ the sand dunes in the Sahara Desert reach up to about 180 metres. It is Atlantic

Objective of experiment * The objective of the experiment is to assess the effect of different pH conditions on enzyme activity. Hypothesis * I feel the pH affected the enzyme activity to produce product. Prediction * If the pH affected the enzyme activity to produce product‚ then rate of reaction will change. Procedure * The procedure that we followed was to take two test tubes and label one pH2 and one pH10 and incubate 1 ml of each solution for 30 minutes. Then after 30 minutes

(or epityphlitis) is a condition characterized by inflammation of the appendix. All cases require removal of the inflamed appendix‚ either by laparotomy or laparoscopy. Untreated‚ mortality is high‚ mainly because of peritonitis and shock.[1] Reginald Fitz first described acute appendicitis in 1886‚[2] and it has been recognized as one of the most common causes of severe acute abdominal pain worldwide. Location of the appendix in the digestive system On the basis of experimental evidence‚ acute

INTRODUCTION There are many reasons for knowing the identity of microorganisms. The reasons range from the knowing the causative agent of a disease to knowing the correct microorganism in order to make antibiotics. This study was done by applying the following methods; OF Glucose‚ Indole Production‚ and Malonate Utilization test for the identification of an unknown bacterium. The methods will assist in determining the unknown bacterium found in a 55 year old male that was passing blood and mucous

Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise
