in weight Using different sucrose concentrations Introduction The purpose of this experiment was to estimate Osmolality of plants cells i.e. Potato and celery by converting the observed change of weight in different sucrose concentrations. The hypothesis assumes that the solute concentration of the plant samples would be indirectly proportional to the weight; there would be decrease in weight as the concentration increases. The independent variable in this experiment would

The Psychological Effect of Popular Media on the Increase of Crime Over time‚ it has been observed that people have a tendency to learn from the world around them and from the people they interact. The phenomenon of learning within a social context by observation can be termed as social learning. Most individuals tend to observe and replicate the behavior of things with which they come in frequent contact and this is more likely to occur if their feel an emotional attachment with the object

given off when different concentrations of catalase are added with hydrogen peroxide. Aim: To see if changing the concentration of catalase (found in celery) with hydrogen peroxide affects the amount of oxygen given of. Background Information: (Hydrogen peroxide - H2O2 1/2O2+H2O) Enzymes: Hundreds of chemical reactions happen simultaneously inside living cells and it’s the job of enzymes to control and regulate the various metabolic activities. Enzymes are biochemical catalysts

Standard. Here it is a dimension such as the contents of a jar of fruit jam‚ the size of a pair of shoes etc. These are called X-bar and R charts. One calculates X-bar-bar and R-bar averages and these are the centre lines of the SPC run-charts that will be drawn. The charts MUST have these centre lines PLUS upper and lower control AND range limits. The points on these graphs MUST be joined so that a reader can follow the level of quality versus centre lines and control limits over time and look for trends

Introduction: The purpose of this experiment is to measure the effects of changes in temperatures and pH on enzyme activity in skeletal muscle‚ particularly the activity of lactate dehydrogenase (LDH). LDH is a glycolytic enzyme which converts pyruvate to lactate in the following equation: LDH Pyruvate+ NADH ------------ Lactate + NAD The reaction above can move in both directions‚

The Effect of Salt Concentration on Osmosis in Potato Cells We should first explain what Osmosis is. It’s a passage of water from a region of high water concentration through membrane to a region of low water. Semi membrane is a very thin layer of material‚ which allows some things to pass through them but prevent other things from passing through. The cells allow small molecules like Oxygen‚ water‚ Carbon Dioxide‚ Ammonia. But will not allow larger molecules like Sucrose‚ Starch‚ or protein‚ etc

What happens? For many reactions involving liquids or gases‚ increasing the concentration of the reactants increases the rate of reaction. In a few cases‚ increasing the concentration of one of the reactants may have little noticeable effect of the rate. These cases are discussed and explained further down this page. Don’t assume that if you double the concentration of one of the reactants that you will double the rate of the reaction. It may happen like that‚ but the relationship may well
