I am choosing to study how the PSI (pounds per square inch) of a football is affected by the temperature. I chose to study this because I like football and I always pondered this question. I believe that this is a worthwhile question to study because these studies can help improve the game as the weather gets colder. As air cools‚ it expands‚ so when a football gets colder‚ the air inside it expands. This expansion causes the air pressure to decrease. The air pressure decreases because the molecules

Research methods: Psychology 232 Effects of amphetamine on locomotor activity‚ and increased dosages leading to sensitisation on rats Jamie Rose Morley 5/10 300159481 Thursday 2-3pm Hypothesis Stewart and Badiani (1993) show in their research that tolerance may develop to a particular effect of a drug whilst at the same time also become sensitised to another effect – could be a little more clearer here. The study also found that tolerance and sensitization can be altered when given in

Effects of Temperature‚ pH‚ Enzyme Concentration‚ and Substrate Concentration on Enzymatic Activity INTRODUCTION Enzymes‚ proteins that act as catalysts‚ are the most important type of protein[1]. Catalysts speed up chemical reactions and can go without being used up or changed [3] Without enzymes‚ the biochemical reactions that take place will react too slowly to keep up with the metabolic needs and the life functions of organisms. Catecholase is a reaction between oxygen and catechol

aim of this experiment was to determine the effect of caffeine on resting body temperature. This has to do with homeostasis‚ which is the maintenance of equilibrium. In other words‚ it is a stable body state. Homeostasis refers to the process of keeping the internal body environment in a steady state‚ when the external environment is changed (Homeostasis 2). Humans are warm-blooded creatures that generate body heat internally and maintain body temperatures at a fairly constant level – about 98.6oF

attempt to observe how enzymes (starch phosphorylase in particular) are affected by varying its temperature before introducing it to the substrate it will be reacting with. A catalyst (enzyme) is a substance that changes the rate of a reaction; for a reaction to take place at all‚ the enzyme must first come into contact with the substrate. Enzymes are subject to a number of factors which effect how fast they can cause a reaction with a substrate; these factors include temperature‚ pH levels‚ chemical

Effect of Catalase at Different Temperatures Abstract The role of this experiment is to determine the effect of temperature on enzymatic activity. The results of the experiment were the colder the temperature the slower the reaction rate and the hotter the temperature the faster the reaction rate. Introduction Enzymes are chemical substances found in living cells and they act as catalysts of the various chemical reactions that occur in them.(Preszler‚ 2012) They bind to substrates that have

Temperature effects on the growth of microorganisms Introduction: The purpose of this experiment was to determine the effects that temperature has on three different organisms. Temperature is one of the most important environmental factors affecting growth and survival of microorganisms². The three organisms used where Escherichia coli‚ Pseudomonas fluorescens‚ and Bacillus stearothermophilis. Most bacteria grow within a particular temperature range. The minimum growth temperature is

The elections effect on society’s increased aggression Elections occur due to the thought during the enlightenment period that people should have the right to choose who they see fit to run the country. Society is given this freedom which often brings out the worse behaviors during and after the elections. People become aggressive in supporting their candidates and issues but this support can translate to increased aggression towards the opposing. The frustrations‚ provocation‚ and reciprocation

particular reaction‚ in order for the reaction to react it needed to find the correct enzyme. (uab) Rennin is an enzyme produced in the inner lining of the abomasum. Renin will solidify milk and makes it curdle. Curdling of milk is essential for the proper digestion of milk proteins in the stomach. (buzzle) Aim: To analyze the effect of temperature on Renin and to find the best temperature for enzyme activity Hypothesis: Renin works the best in which the rate of reaction is at the highest or optimum
