Change in respiratory rate during exercise Aim: To record and investigate how the breathing rate varies for the duration of light and heavy exercise. Introduction: When an individual exercises‚ the muscles being used needs extra energy from oxygen. The lungs pump oxygen to the heart‚ and then the heart pumps the oxygenated blood through the blood to the particular muscle that is working. The human body has a series of organs working together‚ which is named the respiration system. The organs involved

What is the expected rate of inflation in London? iPC - iBC = PC - BC 4.500% - 3.900% =1.250% - BC PC = 0.650% b. Using Uncovered Interest Rate Parity‚ what is the value of the expected spot exchange rate in two years? E(ST) = S0 * [(1+i)/(1+i*)]T E(S2) = 1.3264 * [(1.045)/(1.039)]2

The Effect of Position on Heart Rate This lab explores the effect of head position on an individual’s heart rate by having a subject move it’s head while simultaneously monitoring the subjects heart rate. There were three successive periods during which the heart rate was monitored that occurred in this order: a resting stage (subject sitting upright)‚ a stage with the head positioned between the knees‚ and a recovery stage (subject returns to upright position). The graph depicts a wide range

Introduction The heart is an extremely important organ in the human body‚ and it must be able to adjust the heart rate for when a person is resting or for when a person is running. Heart rate is defined as the number of heartbeats per unit of time‚ usually per minute (Medicine-Net). The heart rate is based on the number of contractions of the ventricles. The pulse is defined as a bulge of an artery from waves of blood that course through the blood vessels each time the heart beats (Medicine-Net). Pulse can

photosynthesis rate. It was predicted that having veins would decrease the rate because chloroplast might be less frequent due to the vascular tissue. For this experiment‚ 4 groups were set up: veins and no veins in CO2 solution‚ and veins and no veins in distilled water‚ the distilled water groups served as controls. These 4 groups were placed under a light bulb in order for photosynthesis to occur. No disks experience movement in the first 7 minutes but at the 8 minute mark‚ 2 disks from the no vein

IN T R O DU CT I ON The term Literacy is defined as the ability to read and write or in other words the ability to use a language for reading‚ writing‚ listening and speaking. In Pakistan the literacy rate is very low; First of all literacy is defined here as the people over 15 years of age who can read and write. According to 2005 estimate 54% percent of the population is literature‚ 63 percent of which are male and the remaining female. Literacy:definition:

Title: Rate of Photosynthesis Introduction: Photosynthesis occurs in plants where the light energy changes to chemical energy. This process occurs in the chloroplast of the plant cell in order to have gas exchange in the organism. Purpose: To measure the effect of light intensity on the rate of photosynthesis in the leaf cells. Hypothesis: The higher the concentration of the sodium bicarbonate solution‚ the faster the leaf of the plant will rise to the surface of the water in the beaker‚ the

We expect to see a greater metabolic rate for the normal rat as opposed to the thyroidectomized rat. The hypox rat is expected to have the lowest metabolic rate. Metabolic rate will increase once thyroxine is injected. TSH will increase the metabolic rate of all the rats with
