Reportage- Natural Disasters: How do they affect the human beings? It is the 31 December of 2004. We are heading for a new year with new expectations‚opportunities and goals. However we have experienced a Tsunami that just very recently struck Thailand. This has left some traces and marks. How has this natural disaster really affected the human beings? I am about to find out. As I walk the beach of Khao Lake I see destruction so far from the paradise pictures I am used of seeing. It is forenoon

People work in different companies and often need organizations that can represent them at work‚ trade unions do exactly that. The purpose of a union is to protect while improving the working conditions of workers. Trade unions exist simply because one person has limited power to challenge or change the decisions that are made about his or her job. By unionizing with other workers‚ chances of having a voice of influence are greater. However‚ there are much arguments about the effect that unions exert

evening class and professor! I chose to discuss topic 2 this week. The topic is Discuss how buffers help to regulate body pH. The pH level in the blood is maintained by the kidneys and the lungs. The pH level on the blood should be at 7.4. In order for the kidneys and lungs to maintain this pH level it affects the buffers in the blood. The buffer is a substance that is resistant to the change in the body’s pH level. Basically the buffers can make an acid or base less potent and try and neutralize

never join but that you try to take on your values (i.e.‚ sport team). How do groups affect us and shape our consumer behavior? Social Power Theory (Raven & French): There are 5 basis of power‚ that is 5 ways in which groups influence people: 1.Rewarded power – parents often use rewards as well as supervisors (lots of ads use reward power) 2. Coercive power (punish) – you can be punished if you don’t do what they want 3. Legitimate power – the other person has a legitimate

on enzyme activity Objective To study the effect of two heavy metal ions‚ lead (II) ions and silver ions on the enzyme activity of invertase. Introduction Hypothesis: The rate of enzyme reaction of invertase decreases and the reaction eventually stops as the heavy metal ions inhibit the enzyme reactions. Biological principle: Heavy metal ions are non-competitive inhibitors. They do not compete with the substrates for the active sites of enzymes. They attach to other parts of the enzyme molecules

Effect of Substrate Concentration on Initial Reaction Rate The purpose of this study is to identify the relationship between substrate concentration and initial reaction rate provided that substrate concentration is much greater than enzyme concentration. Enzymes are essential to life as they are required for many vital metabolic reactions to occur. To adequately explain the properties of enzymes‚ it is assumed that an enzyme-controlled reaction takes place through an enzyme-substrate complex
