Investigative Quest The purpose of this experiment was to find out how music affects the female human heart rate. Hypothesis My hypothesis is that female resting heart rate will increase as the music tempo increases. If the tempo is slower the heart rate will stay at resting heart rate or decrease. Variables The variables used in this experiment were: • The tempo of the music. • The subject’s heart rate. • The subject’s age. Controls The controls used in this experiment were: • How long the subject

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)

Factors that affect exchange rates. Like any price‚ the exchange rate deviates from the cost basis - the purchasing power of currencies – under the influence of supply and demand of currency. The ratio of the supply and demand depends on several factors. It reflects connections with other economic categories - cost‚ price‚ money‚ interest‚ balance of payments‚ etc. There is a complex of interweaving and nomination of decisive factors. Among them are the following. • 1.The rate of inflation. The ratio

Natural rate of unemployment The natural rate of unemployment (sometimes called the structural unemployment rate) is a concept of economic activity developed in particular by Milton Friedman and Edmund Phelps in the 1960s‚ both recipients of the Nobel prize in economics. In both cases‚ the development of the concept is cited as a main motivation behind the prize.[1][2] It represents the hypothetical unemployment rate consistent with aggregate production being at the "long-run" level. This level

metabolic rate are investigated. Hypothesis: With the information given‚ we tested the effects of given hormones on the body by using virtual rats. 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
