Antibacterial activity of medicnal plants has turned out to be a global concern. Medicnal plants are very useful in treating various diseases. Antibiotics are an important class of pharmacological agents used for treating antibacterial infections. Although antibiotics were first isolated from fungi and bacteria but over the years more and more synthetic antibiotics has been synthesized‚ which are in great demand. This present study has been done to determine the antibacterial activity of Cannabis sativa

Introduction: The purpose of this experiment is to test if altering the pH of the milk will trigger a hydrophobic reaction. It will also give me a better understanding of the scientific method‚ hydrophobic reactions‚ and how pH affects substances. If the vinegar and salt are added to the heated milk‚ then the milk will curdle. I came to this conclusion based on common knowledge and the text introducing the experiment. I have not made cheese at home before‚ but I have made Hamburger Helper meals

How is pH affecting catalase activity? Hypothesis The catalase activity is assumed to be the most active in pH7. The higher or lower concentration away from the optimum pH of catalase‚ the slower the rate of activity is. Data Collection & Processing I collected the results of pH4‚ pH7‚ pH10 and pH13 after 2 minutes‚ and I repeated the experiment 3 times. Below is a table to show the results‚ their averages and standard deviations: | 1st time (sec) | 2nd time (sec) | 3rd time (sec)

I believe that extra-curricular activities have an effect on teenage drug and alcohol use. I feel that the more extra-curricular activities people are involved in‚ whether those activities are clubs‚ sports‚ dance‚ hanging out with friends‚ community service‚ etc. that those people are less likely to use drugs and alcohol. However‚ the people who are not really involved in extra-curricular activities are more likely to use drugs and alcohol. The more activities and less free times a person has in

An Investigation on the rate of reaction of the enzyme Catalase on the substrate Hydrogen peroxide. Plan Aim: To investigate the rate of the effect of Catalase on hydrogen peroxide. Introduction This investigation will be carried out to investigate the rate of reaction of the enzyme catalase on the substrate hydrogen peroxide. Enzymes are biological catalysts‚ which speed up the rate of reaction without being used up during the reaction‚ which take place in living organisms. They do this by
