Abstract Over a two week period of time in the laboratory‚ we experimented and tested the reaction rate of a peroxidase enzyme and the factors that affected it‚ both positively and negatively. The purpose of these experiments was to probe and manipulate the activity of the enzyme peroxidase by varying temperature‚ pH‚ the amount of enzyme compared to the substrate and the effect of hydroxylamine. Peroxidase activity is expressed when the potato extract is subjected to stresses such as low temperature

and wonder what he had done to get himself into this mess. Consider the police procedures which make arrestees feel confused‚ fearful‚ and dehumanized. Note that this policeman is wearing sunglasses just like those we had our "guards" wear and as did the head of the National Guards at Attica Prison during its bloody 1971 riot! What suspects had done was to answer a local newspaper ad calling for volunteers in a study of the psychological effects of prison life. We wanted to see what the psychological

The results that were obtained are nothing similar to the expected results‚ the whole experiment was a total fail. The frog muscle was heated for too long‚ so it stiffened before any recording of the results by the machine occurred‚ and there’s also a high probably that the muscle that we assume to have been exposed to heat for too long‚ probably died before the experiment commenced; the reason behind this is that one of the experimenters held the muscle in her bare hand(that was probably salty because

algorithm is used to divide a by d‚ what are the quotient q and remainder r? (a) a = 88‚ d = 11. (b) a = −29‚ d = 9 (c) a = 58237‚ d = 58168 (actual question is a = 58237‚ d = 58168 ) Solution: (a) Because 88 = 11・8 + 0‚ we have q = 8‚ r = 0. (The fact that r = 0 says that 11|88.) (b) Because −29 = 9・(−4) + 7‚ we have q = −4 and r = 7. (Note that although we can write −29 =9・(−3) + (−2)‚ we cannot use −2 as r because r is not allowed to be negative.) (c) a = d(q)+r 58237 = 58168(1)

Research Question: How the amount of vitamin C in fruit juices affects its freshness and till what extent is the information provided on the pack by manufacturers is reliable? Background Information: Hypothesis: -fresh juices have more vitamin C than long-life -juice that is ‘not from concentrate’ is best in terms of vitamin content -if heat destroys vitamin C then heat-treated long-life juices will have lower concentrations -if heat destroys vitamin C then boiled fruit juice will have lower

Abstract An experiment is conducted to prepare soap and thus‚ to compare the properties of the prepared soap and synthetic detergents which are precipitation‚ emulsification and cleaning abilities. It can be concluded that soap has the properties if emulsifying oil whereas detergent has not. The abilities of forming precipitates can be seen clearly in soap solution whereas detergent forms no precipitates at all. The experiment is completed and successfully conducted. Introduction
