shown, the heart rate increases when the athletes are more focused unto fast music than no music and slow music. This determined that, when the athletes ran whilst listening to fast music, it didn’t only improve their timings but their heart rate as well. The beats of the heart rate whether it is slower or faster is highly influential to the tempo of music. The researchers co-founded that when a person is captivated to slow music for a period of 20-30 minutes each day, the heart rate and blood…

Heart rate is defined as the number of heartbeats per unit of time. Heart rate us based on how many contractions of the ventricles, which are the lower chambers of the heart. At the 2013 American Heart Association meeting, which took place in New Orleans, studies show that drinking one to three energy drinks could increase a person's blood pressure and mess with the heart rhythm. The normal heart rate for adults is from 60 to 100 beats per minute. An unusually low or high heart rate can cause…

implementation, the Chinese Government adopted the slogan “Late, Long, Few” (later marriage, longer birth intervals, and fewer births) in 1975, urging each family to have no more than two children. To achieve its goal of lowering population growth rate, the Chinese Government later introduced the One-Child Policy (hereafter called OCP) and created a reward and punishment system to further implement the policy. Rewards and incentives included an increase in hourly wage for family units who…

Concentration on Reaction Rates and Pressure Background - While conducting the Enzyme Lab, students used enzymes as catalysts in order to speed up the reaction processes involved in several tests. Enzymes are substances produced by living organisms that act as a catalyst, while a catalyst is a substance that increases the rate of the chemical reaction. Furthermore, varying amounts of pH and enzymes were added to the mixture in order to determine the substance’s rate of reaction. When the…

determine the rate and order of the reaction. Three trials were done, the first trial acted as a baseline, then the following two trials each varied the concentration of a single reactant, allowing us to calculate the order of the reaction. Additionally, the temperature of the solution was changed to see what effect that would have on the rate. Using this information the activation energy for this reaction could be calculated and compared to the activation energy of the uncatalyzed reaction. …

There are factors that can affect the enzymatic activity. Enzymes are known to speed up the biological reactions. It is specific to its substrate which in this experiment is known to be catechol. The catechol oxidase is used in all parts to express the concentration in the enzyme reacting into ortho-quinone (Schultz, 2006). The catechol oxidase if from the potato that was used in this experiment. The enzyme was extracted as the full strength after centrifugation and used the homogenization as…

and had a reaction rate of 0 seconds-1. The 0.1 v/v % hydrogen peroxide concentration recorded a reaction rate of 0.17 seconds-1. The 0.2 v/v % hydrogen peroxide concentration, recorded a lower reaction rate than the 0.1 v/v% at 0.14 seconds-1. The 1 v/v % hydrogen peroxide concentration recorded higher at 0.49 seconds-1. The 3 v/v % hydrogen peroxide concentration recorded the highest reaction rate at 1.57 seconds-1. The 5 v/v % hydrogen peroxide concentration recorded a lower reaction rate…

The experiment began with a reaction of a 1cm3 cube of lamb liver and 5mL of hydrogen peroxide solution being put in test tubes in a beaker filled with 10℃ water until the temperatures of the liver and hydrogen peroxide were 10℃ also. The liver was put into a 100mL measuring cylinder and the hydrogen peroxide was also poured in as the timer was started. After twenty seconds, several millilitres of froth had been produced from the chemical concoction. This froth was recorded into a results table,…

Purpose To investigate the effect of temperature on the rate of the thiosulphate reaction. Hypothesis If the temperature increases, then the rate of the thiosulphate reaction will also increase. Variables Independent variable: Temperature change in each experiment, which will be varied by increasing the temperature by 10°C each time. Dependent Variable: Rate of reaction, which will be measured by measuring the time taken for the cross to not be visible. Constants: Concentration of HCl and…
