can be visibly seen floating on the top of the water. While surface water pollution is often in the form of trash it can also be chemically based‚ such as gasoline or oil slicks floating on the water’s surface. Groundwater pollution refers to the effects of chemicals (such as pesticides) that seep through the ground and enter water sources that originate underground. Well water is groundwater‚ thus groundwater pollution can be extremely dangerous to the health of humans as well as to the health of

Effects of Temperature and pH on Catalase Activity INTRODUCTION Enzymes are organic catalysts that spur metabolic reactions. The presence of an enzyme within a cell is essential in order for any sort of reaction to take place. All enzymes are complex proteins that act in an organism’s closely controlled internal environment. In such a homeostatic environment‚ the temperature and the pH (concentration of hydrogen ions)‚ remain within a fairly narrow range. Extreme variations in pH and temperature

College General Biology I Enzymes‚ test for effect of pH on catalase activity Purpose The main purpose of this experiment was to learn about enzymes and how to test for the effect of pH on catalase activity and to be able to tell if a reaction is an exergonic or endergonic process. Introduction Enzymes are made from amino acids‚ which are made from proteins. In order to make an enzyme‚ hundreds of amino acids are strung together in a very specific and unique order and eventually is folded

“The Effect of Level of Activity on Clothespin Squeezing Amount Question: Does exercising/ resting affect the number of times you can squeeze a clothespin in a minute? Hypothesis: If the person DOES NOT exercise before the task then‚ they will be able to squeeze the clothespin more because not exercising/resting allows the body to relax and there are no buildups of waste products. Biological Explanation: Both the respiratory system and the circulatory system are involved within my experiment
