The effects of the school activities to the learning achievement of the selected fourth year students of Liceo de San Pedro Academic Year 2009-2010. School activities are those sponsored by and usually held at school but that are not part of the academic curriculum. They often involve some time commitment outside of the regular school day. A school activity serves as a break of the students from their lessons. School activities include both extracurricular and co-curricular activities. School

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

Experiment 4 – Effect of Temperature on Enzyme Activity Aim To study the effects of temperature on the activity of amylase enzyme on starch solution. Introduction Enzymes are widely known as biological catalyst. Almost all cellular reactions are controlled and guarded by enzymes. Virtually every metabolic reaction which takes place within a living organisms are catalyzed by enzymes. Enzymes are complex three-dimensional globular proteins. Some of the enzymes are built up off proteins and

The Effects of Human Activity on Climate Climate is a natural activity that can be defined as the weather conditions prevailing in an area in general over a long period of time (which can include temperature‚ air pressure‚ humidity‚ precipitation‚ sunshine‚ cloudiness‚ and winds) (“Climate”). The climate has been a part of our environment long before humans came to study it‚ and really took it into consideration. Now through the many negative environmental actions created by humans through beneficial

Temperature Affecting Enzyme Activity Introduction The basic properties of life revolve around chemical reactions. Without the presence of enzymes some of life’s processes would not come so easily. Enzymes are basically proteins‚ which have specific shapes for different substrates. Enzymes change the rate in chemical reactions. It does this without having to change its own shape‚ which makes enzymes different from other proteins. A common enzyme that we have is catalase‚ which breaks down
