Part I: Pulse Rate Take your pulse at the wrist‚ as described on the Work Out tab of 4.02‚ and record it below. Your count for 30 seconds ___ x 2 = ___ bpmDay 1 _____Day 2 _____Day 3 _____Total _____ divide by 3 = _____ This is your Resting Heart RateObtain your Maximum Heart Rate (MHR) by subtracting your age from 220. Example 220 – 21 = 199 1. Subtract your resting heart rate (RHR) that you calculated in Part II above from the maximum heart rate (MHR) that you just determined in Step

Literature Review The human heart is a very complicated organ‚ with the main purpose to pump life sustaining blood throughout the human body. It also supplies oxygen and nutrients to all areas and clears harmful waste from the body. The heart is made up of cardiac muscle which beats on its own. According to the article ‘heart ‘which was written by The National Geographic the heart will slow down or speed up depending on how the body is being used. This is done by nerve signals which are being

First of all‚ if you look at this paper‚ you can see that this watch has a function that has never been designed for before – a heart rate monitor. It enables the users to measure their heart rate while doing exercises. Actually‚ the underlying purpose of this design is to immerse into customers’ daily lives. Let’s imagine that‚ when you

them. However‚ if the rate of reactions are too low‚ they will not be able to sustain lives. In this case‚ they have enzyme as a protein catalyst. As reaction catalysts‚ enzymes are proteins that adjust the process by initiating the reaction. In this case‚ there are also many elements that influence enzyme working rates. For example‚ most living things hold a constant PH value. It is reasonable for people to doubt that PH value of surroundings will influence enzyme working rates. Also‚ livings will

Caffeine on Daphnia Heart Rate: Aim: To investigate the effect of caffeine on the heart rate in Daphnia. Hypothesis: My hypothesis is that as the caffeine content increases‚ the heart rate if the Daphnia increases. Equipment: * Culture of water flea – Daphnia * Caffeine of 5 different concentrations * Microscope * Counter * Cavity Slide * Pipettes * Stop clock * Distilled water * Test tubes * Petri dish Method: 1. Remove one Daphnia and place

Aim: To examine and dissect a sheep’s heart‚ to observe it’s structure as a two-part pump and it’s features. Hypothesis : That the left side of the heart will be bigger because the left side of the heart pumps blood around the whole body. Apparatus: Gloves Dissection Board Sheep’s heart Scissors Aluminium Foil Newspaper Method : The heart was laid out with the septum coming diagonally from the upper right side to the lower left side. The heart clambers were observed‚ examined and recorded

Creatine is a substance used by athletes and bodybuilders to increase the production of Adenosine Triphosphate (ATP)‚ which gives them the energy they need to perform. In this experiment‚ creatine is added to water and its effects on Daphnia is tested. By observing the heart rate‚ one can determine if the creatine increases or decreases heart rate. Heart rate was chosen to be measured because one can then see how creatine affects the heart. If it is unhealthy for the Daphnia‚ it could potentially

Substance abuse and substance dependency are more alike than they are different because they both involve the overindulgence in illicit drugs or alcohol. Substance abuse seems to be the stage before dependency being that one has to excessively use the drug in order to become dependent. Once a person becomes dependent on an illicit substance they are prone to becoming functioning addicts where the abuse is ongoing. The only real difference between the two is that substance dependency allows one to

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
