Investigate Concentration of Substrate on Catalase enzyme 1. Aim/Prediction. Aim of this experiment is to investigate concentration of substrate on catalase enzyme‚ as well to see how they work in different concentrations of hydrogen peroxide (H2O2). Prediction would be‚ that the filter paper discs that were used‚ will rise up to the surface in a time in the tube of different concentration of hydrogen peroxide. And in different concentrations the time will be different. As higher the concentration

This visual is a strong statement about a time when America was in the grips of the Vietnam Conflict and the possibility of drafting little boys who were soon to become young men. In the last 40 years advertisements have considerably changed

An experiment proving transpiration in leaves Aim To see how different environmental conditions affect transpiration of a leaf and which side of the leaf transpires the most. Background Information Plants put down roots into the soil to draw water and nutrients up into the stems and leaves. Some of this water is returned to the air by transpiration (when combined with evaporation‚ the total process is known as evapotranspiration). Transpiration rates vary widely depending on weather conditions

Basic chemistry of a cell Properties of water – – – Life on Earth began in water and evolved there for 3 billion years before spreading onto land. Modern life‚ even terrestrial life‚ remains tied to water. All living organisms require water more than any other substance. Human beings for example‚ can survive for quite for a few weeks without food‚ but only a week or so without water. – – – Water is deceptively simple. It is shaped something like a wide V‚ with its two hydrogen atoms joined

The relations between Media and the Military and whether or not they should be controlled. Control of the media in regards to their access to the frontline yet also operational inclusion has been a controversial issue during the last century. Operational security‚ due to media’s reporting is being breached and often putting the lives of soldiers at risk with public animosity against the government. What people seem to forget is that despite the actions and events occurring during war times‚ while

Pre-lab 1: Identifying Carbohydrates Abstract The point of this lab is to determine if a substance contains carbohydrates such as a reducing sugar and/or polysaccharides. This will be done by using Benedict’s reagent and Iodine stain tests. Benedict’s reagent will react to reducing substances in the solution by oxidizing it and changing the structure of the reducing sugar to form a colored precipitate. The color of this precipitate can be used to determine the concentration of reducing sugars in
