2012 Teenage Birth Rate Rises Do you know where your tax dollars are being spent? Every year the government is spending tens of millions tax dollars on programs that hurt our children‚ mainly abortions. Abortions rates have risen over the years because teen sex rates have also climbed and the condom use rates has plummeted. Therefore‚ the most important issue facing our nation’s young people today is the use of abortion as a means of contraception. In this piece we will explore the increase/

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

The Pros and Cons of Immigration Immigration is a complex subject with many pros and cons. Except for Native Indians‚ every family in the U.S. has immigrants in their ancestry. Immigrants are a large part of our society and add diversity to our society. Without immigrants our country would not be what it is today. First I will start with the pros of immigration. • Immigration gives people come from a suppressed country a chance for a new start in their lives. It also gives them a clear picture

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

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

Unemployment Rate in Japan. Figure 1.2 Labor participation rate for total‚ male and female. Figure 1.1 Shows unemployment rate is on the upward rising trend since year 1980 to year 2008. An increase in unemployment is seen from year 1980 to year 1986‚ then follow by a slight decrease in year 1987 to 1991 and continue to increase steadily from year 1992 to 2002 reaching a record of 5.4% high unemployment rate in year 2002. However‚ from year 2003 to 2008‚ a decrease in unemployment rate is observed

environments affecting the rate of reaction‚ PNPP (p-nitrophenyl phosphate) + H20 ? PNP (p-nitrophenol) + H3P04. This reaction is catalyzed by the enzyme phosphatase. Different environments produced different reaction rates as environmental factors affect the efficiency of phosphatase. This is because environmental factors can change the tertiary structure of phosphatase‚ which alters its active site‚ and thus changes its efficiency to catalyze the reaction. We measured the rate of reaction‚ by using

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

Title: Kinetics: The Rate of a Chemical Reaction Objectives: 1. To study the kinetics of chemical reaction‚ 2 I- + S2 O82- I2 + 2 SO42- . 2. To study the effects of reactant concentration (persulphate‚ S2O82-‚ and iodide‚ I-) and temperature on the rate of chemical reactions. ( i) Study the effect of 0.20M (S2O82-) on the rate of chemical reaction. ( ii) Study the effect of 0.10M (S2O82-) on the rate of chemical reaction. ( iii) Study the effect
