developed over time within participation in sports. I have found two articles arguing why kids should participate in sports and how it affects their behavior in a positive way. The first article argues First Article: Youth problem behaviors‚ such as truancy‚ violence‚ and substance use‚ are alarming to parents‚ teachers and youth alike. These behaviors disrupt the learning environment and lead to serious social and economic problems. Some experts have argued that rather than trying to prevent individual

All economic activities affect the environment in some way whether it is done intentionally or unintentionally. These could be positive or negative effects. Most of the time‚ they are negative. Most activities usually end up harming ecosystems or just polluting the environment. Economic activities can range from mining all the way to farming. This essay will discuss different types of economic activities and how they effect the environment. The first effect on the environment is the over harvesting

Topic: Some people believe that the Earth is being harmed (damaged) by human activity others feel that human activity makes the Earth a better place to live. What is your opinion? Nowadays the Earth faces a number of serious problems‚ such as the environment pollution‚ the increasing population‚ the fatal effects of nuclear weapons‚ etc. The problems arising from not just development in terms of science and technology but also the increase in human demands based on population and economy.

Does physical activity help improve memory? And‚ if so‚ what kinds of physical activity improve memory the most? Memory is defined as the faculty or capacity by which the mind retains‚ stores‚ and revives information and recognizing previous experiences. It is the process of remembering. Memories come from different areas of the brain and different sets of cells. When someone experiences something‚ or even notices something‚ a pulse is fired inside the brain‚ connecting two cells. As something happens

Factors affecting Enzyme Activity: The effect of pH on enzyme activity Background Knowledge: An enzyme is a biological catalyst – which speeds up the reaction rate‚ without itself getting altered. Enzymes are proteins with long polypeptide chains that are folded up into three – dimensional shapes. An enzyme acts on a substrate to convert the substrate into a product useful for the organism.The active site is a special region on the surface of the enzyme where the substrate binds to the enzyme.

HOW DOES ICELAND UTILIZE VOLCANIC ACTIVITY TO ITS ADVANTAGE? Geothermal energy. The first reason why Iceland utilizes its volcanic activity to its advantage is by using geothermal energy. Geothermal energy production works by the radioactive decay f several types of rocks containing radioactive substances (such as uranium) releasing heat energy. In the volcanic areas in Iceland‚ the rocks heat the water so that it then rises to the surface (naturally) as hot water and steam. The steam can then

Enzyme Activity How does temperature affect enzyme activity? In this practical investigation‚ my aim is to discover how temperature will affect enzyme activity‚ by looking at the rate of reaction. I predict that the higher the temperature will be‚ the faster the reactions take place. However‚ I also think that there will be an optimum temperature‚ at which the reaction will work at its fastest; if the temperature goes beyond that‚ the reactions will stop altogether as the enzymes would have
