the water diffused at a higher temperature. Temperature can also affect the rate of diffusion because a higher temperature will cause molecules to move faster and increase the rate of diffusion‚ allowing more pigment to pass through the membrane‚ in the 5 minutes given‚ giving a more pink/red color to the water surrounding the beetroot at a higher temperature‚ and at lower temperatures slowing down the molecules and making the rates of diffusion lower in colder temperatures‚ giving it a paler appearance

different amount of sucrose concentrations. The higher molarity concentrations increased the movement of water to balance out the inside of the tube and the beaker. The greater amount of concentration gradient‚ in each tube‚ increased the rate of osmosis. This rate of osmosis is due to the net movement of water from an area of low concentration to an area of high concentration. Because the tubes had different concentrations‚ certain tubes gained more mass than others. Solution A had 0.6 molarity

heat. If an enzyme has been denatured it means the shape has been altered therefore cannot perform its function‚ many factors can cause this including high heat. The hypothesis is if temperature is increased the amount of activity rate will increase. The results for the rate of oxygen production (dependent variable) will increase as the heat increases. The reason is a chemical reaction to the heat gives it energy. Enzyme reactions are important to life because “Enzymes are proteins that control the

A potato will be the substance used to determine how different temperatures affect this enzyme. This experiment has a control‚ independent‚ and dependent variable. The control variable is the size of the filter paper‚ the amount of potato in the experiment‚ and the amount of hydrogen peroxide used. The independent variable

“How Risky is Risk” 1. Introduction ‘’The human understanding‚ once it has adopted an opinion ‚ collects any instance that confirm it‚ and though the contrary instances may be more numerous and more weightly‚ it either does not notice them or else rejects them‚ in order that this opinion will remain unshaken.’’ Francis Bacon‚ 1620. Risk is a very interesting thing; people normally tend not to realize the real effect that risk takes in their lives. There are many kinds of risk‚ we want to focus

The effects of different wavelengths of light on the rate of photosynthesis Introduction This experiment was performed to investigate the effects of different wavelengths of light on the rate of photosynthesis. If a multiple colored film petri dishes are place under a 50 watt lamp‚ then the rate of photosynthesis will be greater for those with red‚ blue and clear film‚ than those with green and black film. We believed the petri dishes with the red‚ blue and clear film would produce the best

family own an automobile? Most likely they do. With approximately 95% of the US population owning cars and other motor vehicles‚ they have certainly made an impact on our daily life. It wasn’t always this way‚ though. Humans have tried for decades to create a self-moving vehicle‚ but it was Karl Benz who finally succeeded in 1885‚ and they’ve come a long way since.Owning an automobile can have many risks‚ however‚ the benefits certainly outweigh those in terms of convenience‚ efficiency‚ and productivity

expectations from a project. Project risk management includes the processes concerned with identifying‚ analyzing‚ and responding to project risk. It includes maximizing the results of positive events and minimizing the consequences of adverse events. Generally‚ risk is a choice in an environment rather than a fate. BS 6079 (British Standard Institution 1996) defines risk as ‘It is the uncertainty inherent in plans and possibility of something happening that can affect the prospects of achieving‚ business

specific conditions to function‚ thriving at temperatures between 29°C-40°C‚ with an optimal temperature of 37 °C. Above 37°C‚ rennin molecules increase in energy causing the rate of reaction to increase‚ becoming denatured at approximately 60°C. Below 37°C‚ the reduced energy level results in fewer collisions and the rate of reaction and activity of rennin decreases. (7) The optimum pH for rennin is pH 3.4 (8) as it mimics the gastric juices and acidic conditions of the stomach‚ however again rennin
