heart rate to speed up‚ decrease‚ or stay the same‚ the volume of sound has a high effect on the heart. However‚ if people will let down the volume of sound‚ others would not be mannered by the increase in volume managing to the deadly heart attack. Sound within the community‚ for instance‚ traffic can cause a human’s heart rate of increase. Problem of heartbeat tends to be solved by seeing what kind of sound causes the increase of heart rates to place a termination to increase of heart rate. If

Introduction: The rate of photosynthesis varies greatly with changes in wavelengths of light. Light’s colour is determined by its wavelength of light‚ and thus it is possible to devise an experiment to determine which wavelengths of light are most productive for photosynthesis than others. In this experiment I use a plant called Elodea (pond weed). Elodea is native to North America and it is also widely used as aquarium vegetation. The basic structure of these plants are whirls of leaves around

crystallizes in the hexagonal form with the space group P63/mmC(194). This inter oxide is of considerable interest to materials scientists owing to its ability to accommodate a high degree of anion vacancies‚ crystal structure and its high Neel Temperature (TN). It also exhibits polymorphism with two different cubic and hexagonal structures. The value of TN was reported to be 350 K by Chamberland et al [ ] corresponding to anti ferromagnetic ordering. However‚ Battle et al [ ] concluded TN to be

Practical: The Effect of Concentration on Reaction Rate Aim: To use a simple reaction between sodium thiosulphate and hydrochloric acid to discover concentration this determines how fast chemical reactions occur. Independent Variable: Concentration of hydrochloric acid (%) Dependent Variable: Time taken for chemical reaction to take place (sec) Hypothesis: My prediction is that the increased concentration of the thiosulfate will in turn lead to an increase in the rate of reaction. This

Investigate the effect of on exercise on the heart rate. Aim: To find out if there is any relevant link between the amounts of exercise taken to increase a person heart rate. Equipment needed: Stop watch Screen volunteer P.E kit Calculator Record sheet Type of exercise: skip for few minutes ‚ then break in between and again repeat it once or twice. Method: First of all‚ we needed to take the resting heart rate of the person who is about to skip. Then‚ with the stopwatch one

Effects of Temperature and pH on Catalase Activity INTRODUCTION Enzymes are organic catalysts that spur metabolic reactions. The presence of an enzyme within a cell is essential in order for any sort of reaction to take place. All enzymes are complex proteins that act in an organism’s closely controlled internal environment. In such a homeostatic environment‚ the temperature and the pH (concentration of hydrogen ions)‚ remain within a fairly narrow range. Extreme variations in pH and temperature

Carbon Footprint briefly defined is the amount of CO2 left behind after any human activity. They can be classified into primary and secondary footprints. [ (McLean 2008) ] Primarily‚ it is the direct emission of CO2 from burning fossil fuels or any kind of fuels. They are considered the main and biggest source of CO2 emission‚ thus the having biggest Carbon Footprints. [ (McLean 2008) ] The CO2 emissions from all products and their life-cycles are considered as secondary footprints. The life-cycle
