results a final conclusion can be drawn. The hypothesis was supported by graph 3 and 6 which both showed that an increase in concentration of the reacting species resulted in an increase in reaction rate. Both graphs have a positive gradient which clearly indicates that concentration increases the reaction rate. The hypothesis also proposed that as temperature increases the speed of the reaction would decrease‚ this is evidenced in graph 7 which shows a negative decrease in time as the temperature of the

Heart Rate Vs. Exercise & Gender Introduction The purpose of this experiment was to find out whether males or females of the same fitness levels had a higher increase in heart rate after performing the same exercise in the same amount of time. The hypothesis was that‚ with the same levels of fitness‚ females would have a higher heart rate. The main reason that this hypothesis was thought to be viable‚ was because females generally have higher heart rates than males due to their smaller heart size

effect of exercise on heart rate Word Count THE EFFECT OF EXERCISE ON HEART RATE Abstract - Aims - This study is to ascertain‚ if there is an effect on heart rate after exercise. This is being done to see‚ if there is a difference between resting heart rate and heart rate after performing exercise. Method and results - The study was compiled of seven female students from the University of Huddersfield. For the exercise a step was used‚ a polar heart rate monitor was used for each

Relationship Between Body Temperature and Heart Rate? Statement of Research Question: This study sets out to determine whether there exists a difference in the average body temperature between males and females. Furthermore‚ the study aims to determine whether an increase in heart rate corresponds with an increase in body temperature. Data Collection: The data was obtained from the article “What’s Normal? -- Temperature‚ Gender‚ and Heart Rate” (Shoemaker‚ Allen 1996) as found in the Journal

A reaction is a chemical process in which substances decomposes‚ or combines with other substances. In this case it is synthesis chemical process which creates new products. However‚ the rate of a reaction can be altered either faster or slower depending on certain variables. These variables are concentration‚ temperature‚ surface area‚ and catalysts. A reaction can be made faster or slower with a variation in the concentration of reactants; a reaction goes faster when there is an increase in concentration

IntroductionThe purpose of this experiment is to determine whether or not caffeine has an affect on the heart rate of DaphniaHypothesisThe Daphnia heart rate will increase with the concentration of caffeine. I based my hypothesis on the fact that humans heart rates increase with caffeine as it acts as a stimulant drug. In the experiment there will be several variables that I need to try and control‚ the temperature of the water is one of these because if the temperature is higher or lower on the

BMR (basal metabolic rate) Basal metabolic rate (BMR)‚ and the closely related resting metabolic rate (RMR)‚ is the amount of energy expended while at rest in a neutrally temperate environment‚ in the post-absorptive state (meaning that the digestive system is inactive‚ which requires about twelve hours of fasting in humans). The release of energy in this state is sufficient only for the functioning of the vital organs‚ the heart‚ lungs and kidneys and the rest of the nervous system‚ intestine‚

Why are floating rates considered to be superior to fixed rates in dealing with major shocks such as oil price increases? Explain why floating exchange rates did not produce a reduction in the US balance of payments deficit during the early 1980s? Describe the system that was developed to replace floating exchange rates. First we need to explain what fixed and floating exchange rates are. Fixed exchange rate regime is a regime in which central banks buy and sell their own currencies to keep
