Lab #6: pH Effects and Enzyme Concentration on Catecholase Activity Abstract: This experiment examined the effect on how the changes in pH balance of potato juice affected the enzyme activity‚ structural stability and solubility. Introduction: Enzymes are macromolecules that allow chemical reactions to occur. They function as biological catalysts. A catalyst is a substance that is involved in‚ but not changed by or consumed in‚ a chemical reaction. The amount of energy required for a reaction

Claire Kerns Bio Per.1 2-13-13 Cancer reflection Is cancer a disease due to genetics or environment? Cancer is a disease both caused by genetics and environmental factors. Each person has either proto-oncogenes or oncogenes. These are the genes that are responsible for regulating cell division. When a person has an oncogene it is a mutation of a proto-oncogene. The oncogene (dominant gene) tells the cell to continuously divide. This can be a problem if the cell is cancerous. Cancer cells

but we selected makahiya (mimosa pudica) and malunggay (moringa oleifera) and used rats as our subject. We measured 1 centimetre each tail of the rats and using a scalpel‚ we maim it. After that‚ we used makahiya extract to treat one of the rats and the other is treated with malunggay extract from the leaves. After a few days‚ we noticed that the wound treated with malunggay reduced its length from 1 centimetre to 0.5 centimetres. On the other hand‚ we noticed that the wound treated with makahiya reduced

Multivariate analysis of variance (MANOVA) is a generalized form of univariate analysis of variance (ANOVA). It is used when there are two or more dependent variables. It helps to answer : 1. do changes in the independent variable(s) have significant effects on the dependent variables; 2. what are the interactions among the dependent variables and 3. among the independent variables.[1] Where sums of squares appear in univariate analysis of variance‚ in multivariate analysis of variance certain positive-definite

electronegativity‚ bond polarity‚ and molecular polarity Introduction: In this atomic-level simulation‚ you will investigate how atoms’ electronegativity value affects the bonds they produce. When two atoms bond‚ a pair of electrons is shared between atoms. Electronegativity is a measure of a single atom’s ability to hoard electrons shared in that bond. In this lab you will work diligently‚ at your own pace‚ to answer a number of questions. To begin‚ from what you’ve already learned about the protons
