Crime rates vary by region. For many years‚ southern states have had higher crime rates in almost all crime categories especially violent crimes; so called a “southern subculture of violence”. Although the “lead” has changed so many times in recent years between the South and the West that the FBI’s Uniform Crime Report has indicated that the South has once again lead the nation in violent crime.

The US has recently reached the lowest unemployment rate： 4.5%. In this article‚ the author provided different aspects of US’s low unemployment rate and the result of such a low unemployment rate. Comparing to the unemployment rate (10%) after 2008’s recession‚ US is now reaching a relatively low unemployment rate. A low unemployment rate is one of the four macroeconomic objectives that economists always want their nations to achieve. Unemployment is simply defined as the state of being out of

initial rate of reaction. I will measure the effect of the enzyme in 5 different concentrations against the controlled variable of the reactant. The enzyme which will be used is different concentrations of potato and the reactant used will be Hydrogen Peroxide. Hydrogen Peroxide which will be the buffer solution is a PH of 7.2. My hypothesis for the experiment is that as the concentration of the enzyme is increased the rate of reaction will be increased‚ producing oxygen at a faster rate. The results

Aim: The rate at which a reaction occurs‚ or takes place‚ is affected by various factors‚ such as the temperature at which the experiment is conducted in‚ the pressure which is given‚ the surface area which is exposed‚ use of catalysts‚ and the concentration. In this investigation‚ I would be investigating the affect of surface area‚ or particle size‚ in the rate at which a reaction occurs. Background Information: The more finely divided the solid is‚ the faster the reaction happens. A powdered

Investigation of the rate of photosynthesis of pondweed. Research question: How does the concentration of sodium bicarbonate relate to the amount of oxygen produced by Elodea (Canadian pond weed) in the process of photosynthesis? Hypothesis: If there is an increase in concentration of sodium bicarbonate the amount of oxygen produced will increase because the sodium bicarbonate concentration will increase the carbon dioxide levels. Independent variable- Concentrations of sodium bicarbonate (8%

on cardiovascular functions such as pulse rate‚ pulse lag‚ the PT interval‚ the TP interval‚ systolic‚ and diastolic blood pressure is noticeable after running down the steps of Long Hall and back up to the third floor. As Table 1 shows‚ the data support the initial hypothesis that the pulse rate will increase‚ the pulse lag will decrease‚ both the PT and TP intervals will decrease‚ and the systolic and diastolic blood pressure will increase. The pulse rate mean before exercise was about 78 beats per
