The effect of varying temperature on thee Rennin enzyme Abstract The purpose of this experiment was to see what affect different temperate had on the reaction rate of the enzyme rennin. The experiment was performed by placing test tubes filled with renin and milk into water bath which was heated or cooled to one of the temperatures trialed. The hypothesis justified because it found because it though data that the enzyme reacted faster with the 45° temperate because it was

“UNSAFE DRINKING WATER” An adequate supply of safe drinking water is one of the major prerequisites for a healthy life‚ but waterborne disease is still a major cause of death in many parts of the world‚ particularly in children‚ and it is also a significant economic constraint in many subsistence economies. The basis on which drinking water safety is judged is national standards or international guidelines. The most important of these are the WHO Guidelines for Drinking Water Quality. The quality

The liver is the largest organ in the entire‚ normal human body. It weighs anywhere from 2.5 to 3.3 pounds. With its large size it is also a very resilient organ. Up to 3/4 of its cells can be removed before is ceases to function. It is red-brown organ roughly shaped like a cone. The liver is located in the upper right abdominal cavity immediately beneath the diaphragm. Without the liver‚ we could not survive. It serves as the body’s chemical factory and it regulates the levels of most of the main

NOSOCOMIAL INFECTIONS Nosocomial Infection is an infection that occurs in a hospital of hospital-like setting. Approximately 10% of American hospital patients contract this infection. There are three factors as to why nosocomial infection exists: 1. A high prevalence of pathogens. 2. A high prevalence of compromised hosts. 3. Efficient mechanisms of transmission from patient to patient. These three factors alone lead not just to a higher chance of transmission
