Based off the results from this lab the student was able to determine and have an overall better understanding of the variables that affect the rate of photosynthesis in a plant. The first variable the student tested in the lab was 30cm of light with CO2 present. The student started this trial with all 10-leaf disks and timed how many leaf disks came up every minute for 15 minutes. One minute into the trial and the student recorded that no leaf disks had yet to rise to the top of the solution. At

3 Factors that Influence Rate of Return Any bondholder‚ or any investor for that matter‚ will allow three factors to influence his or her required rate of return. The three factors are the following: real (pure) rate of return‚ inflation‚ and risk premium. These three factors equal the risk free rate which is the rate of return of an investment with no risk of financial loss. This is also the rate that investors would expect from an absolutely risk-free investment over a period of time.

The affect of psychological stress on the heart rate. Introduction: The human body is incredible machinery that can adjust to stressful situations and react in a “fight-or flight” manner by temporarily shutting off nonessential‚ at the moment‚ immune and digestive systems. When the body is ready for a challenge‚ heart rate increases‚ blood pressure rises and glucose production intensifies to supply large amounts of energy. These metabolic changes are caused by release of stress hormones (catecholamine

concentration on the rate of enzyme activity of Catalase Aim To investigate the effect of substrate concentration (manipulated by increasing concentration of hydrogen peroxide) on the rate of enzyme activity of catalase‚ produced by liver cells‚ on the decomposition of hydrogen peroxide. Introduction Enzymes are biological catalysts that increase the rates of reactions. In an enzyme-catalyzed reaction‚ the substrate binds to the active site and forms enzyme-substrate complex with the enzyme through the

Enzyme Activity Lab Hypothesis: 1] Are enzymes reusable? Yes‚ enzymes are reusable. 2] Which of the following do you think contain catalase? [Manganese dioxide‚ chicken meat‚ apple‚ carrot‚ potato‚ or chicken liver] I think that the manganese dioxide‚ apple‚ and carrot contain the catalase. 3] Would grinding the materials affect enzyme activity? I think that grinding the materials will increase enzyme activity. 4] Would temperature affect enzyme activity? I think that

A factor that may affect communication is the use and abuse of power. In health and social care effectively every care provider has power over all patients on what standard of care they receive. The word power is defined as….. “The capacity or ability to direct or influence the behaviour of others or the course of events” - http://www.oxforddictionaries.com/definition/english/power Often when we communicate there is always an overall power within that communication.

As the temperature increased‚ the enzyme activity also increased‚ however‚ only to an optimal level which was at temperature 32oC. Once the temperature was beyond the optimal level‚ the rate began to decline and this was represented by the concave curve on figure 5 and 7. This was because as the temperature increases‚ the frequency of collisions between the enzyme and the substrate also increased hence faster reaction rate. Whereas‚ the enzymes operated slowly at low temperature as there wasn’t sufficient

used to convert inorganic compounds into organic substances with the subsequent release. There are many factors which can have an effect on the process of photosynthesis; in this laboratory experiment‚ the focus lies on carbon dioxide (CO2) availably and its effect on photosynthesis. By understanding the component that affect the rate of photosynthesis‚ one can do work to try and increase the rate of photosynthesis. The purpose of this laboratory experiment was to determine which solution would have

Factors affecting the rate of coastal erosion Rock types - Soft rocks like clay or mud‚ erode faster than hard rocks like granite. This is because hard rocks are more resistant to erosion. This means that the hard rock is left sticking out into the sea as a headland. The headland is now vulnerable to the force of destructive waves but shelters the bays close by from further erosion. Wave type - Destructive waves cause more erosion than constructive waves. This is because backwash is more powerful
