Discussion Heart Rate Our hypothesis stated 1.) The heart rate increases substantially when a person performs a physical activity and 2.) Females have heart rates greater than males’. In this experiment we measured the resting heart rates and exercise heart rates of both the male and females that are in the class. We calculated the results that were taken by each member of each group in the class (6 males and 16 females total). The average resting heart rate for women was 71.8 beats per minute

and willing to work yet is unable to find a job. Unemployment rate is the number of people officially unemployed divided by the labor force. Official unemployment measures those over the age of 16 who are able for employment‚ but are unable to obtain a job. The labor force is the number of people over the age of 16 who are either employed or unemployed. In year 2005‚ unemployment rate in Malaysia (3.0%) higher than unemployment rate in Cambodia (2.5%).

Crime rate is basically defined as the number of Criminal Code offenses in an area reported to the police per 100‚000 population in that area (StatsCan‚ 2016). Crime rates provide an insight about the society and the deviance going in and around it. Crime rates steadily dropped in most countries in the 1990s but the most drastic change seen was in the North American region. According to Understanding why crime fell in the 1990s written by Steven D. Levitt‚ the homicide rates in The United States

and Effects on High Divorce Rates Since the past‚ people have gotten married and lived together. Some married couples are unable to maintain their relationship as a couple; therefore‚ they choose to get a divorce. Furthermore‚ half of American marriages now end in divorce. There are three main causes to this increase in divorces: the changes in women’s roles‚ stress in modern living‚ and lack of communication. The first significant cause in the rise in the divorce rate is that women have changed

Lab 2: Reaction Order and Rate Laws Khadijah Maraheel Location: My apartment September 27th-28th 2017 Course Number: Chem112 Abstract: The purpose of this lab is to find the rate law of the reactants and the reactions order. My beginning thought was I would find whole numbers but that would be to easy. My answers were all with decimals. I found that my rate law Is k (HCl)1.36 (Na2S2O3)0.84. I was expecting the solution to change color but I never thought it would turn

AIMS The aim of this experiment was to investigate the effect of temperature rise on the rate of transpiration of a plant (hibiscus) by measuring the plant’s water uptake in a period of time. HYPOTHESIS Transpiration is the process by which plants loses water to the atmosphere from their leaves. Water in the plant is lost to the atmosphere by evaporation. Evaporation of water can occur at any temperature. In the presence of sunlight‚ water in the plants evaporates into the intercellular air

The rate of a chemical reaction is the measure of change in concentration of the reactants of the change in concentration of the products per time. The rate of a chemical reaction is influenced by the concentration of the reactants‚ temperature‚ and the presence or absence of a catalyst. Through finding the time and concentrations of the reactants‚ it is possible to find the rate of reaction and k. To perform this experiment‚ you need two erlenmeyer flasks‚a timer‚ a LabQuest with a temperature

The Effect of pH on Enzymatic Reaction Rate Abstract Enzymes are affected by changes in pH. The most favorable pH value— the point where the enzyme is most active—is known as the optimum pH. This experiment was conducted to determine the effect of pH reaction rate on an enzyme‚ catalase‚ from yeast. The experimental results indicate that the catalase worked best at a neutral pH level of seven (7). Introduction An enzyme is a protein molecule that serves as a catalyst. “The basic function of

Riddick Strayer University Professor Susan Wind April 28‚ 2013 When it comes to any type of crime it is just not a good picture to paint. All across the nation crime is a worldwide problem that directly indirectly touches every one of us in multiple ways: as victims‚ in paying higher prices for products and services‚ and in living with the consequences of fear and corruption.
