With our question, we need to know how long it takes for sugar to affect someone’s heart rate. The first experiment that I looked at said that it takes 1 minute to make their heart rate change. On the same website, there was one that said three minutes. In the end we decided to comprise it the middle at two. After looking at other similar experiments we came to the conclusion that it will take approximately 2
One topic that is a big part in the experiment, testing how reaction time is affected by the influence of peppermint candy, is reaction time. Reaction time can be defined as the amount of time an organism takes to respond to stimulus, or a thing or event that evokes a specific functional reaction in an organ or tissue. For example, the International Encyclopedia of The Social Sciences explained reaction time
For further investigation, a larger sample size should be used, along with repeating the experiment on several different days to minimise the effect of random errors on each subject’s specific result. Reference List: BBC 2014, Respiration, BBC, accessed 1 September 2015,.
For both experiments, data were collected for thirty seconds.
We then took 1ml of the 1% solution from test tube 1 using the glucose pipette and added it to test tube 2, we then used the H2O pipette and added 9ml of H2O into test tube 2 creating 10ml of 0.1% solution
Over a three week period a test subject was instructed to come to the exercise physiology lab once a week. The purpose of the first week was to determine the baseline test data for the participant. During this first week, the subject was asked how many hours of sleep they had gotten the night before and how much they weighed. The subject was then instructed to put on a heart monitor and wear an O2 apparatus and begin running on a treadmill. This treadmill was set at zero incline for the beginning of the run until three minutes had passed. At the three minute mark the incline increased by 2.5%. After this the incline was continuously increased by 2.5% every two minutes. During this process, the VO2 and RER exchange rate of the subject was being tracked through the O2 apparatus. Their heart rate was recorded every 15 seconds. In addition, the subject was asked their perceived exertion at every increase in incline. The subject continued to run until they could not run anymore, at this time they would hop off the treadmill.
According WebMD 2014. Diabetes mellitus (or diabetes) is a chronic, lifelong condition that affects your body's ability to use the energy found in food. There are three major types of diabetes. Type 1 diabetes mellitus, type 2 diabetes mellitus and gestational diabetes. It is a hormonal disorder of the pancreas either decrease in insulin level also known as hypoinsulinism or increase in insulin level also known as hyperinsulinism. Lowered amounts, insufficient of, or ineffective use of insulin leads to the disorder of diabetes mellitus. It is common chronic disease requiring lifelong behavioral and lifestyle changes. According to Peakman (2012). The development of type 1 diabetes mellitus is a genetic and an autoimmune process that results in destruction of the beta cells of the pancreas, leading to absolute insulin deficiency. There is usually a pre-diabetic phase where autoimmunity has already developed but with no clinically apparent insulin dependency. Insulin autoantibodies can be detected in genetically predisposed individuals as early as 6-12 months of age. In persons genetically susceptible to type 1 diabetes, a triggering event, possibly a viral infection the leads to production of autoantibodies that kill the beta cells and results in decline and a lack of insulin secretion. According to Wherrett. It is caused by impaired insulin secretion and insulin resistance and has a gradual onset. Those with type 2 diabetes may eventually need insulin treatment. Gestational diabetes mellitus is glucose intolerance during pregnancy in a woman not previously diagnosed with diabetes, this may occur if placental hormones counteract insulin, causing insulin intolerance. Complications in diabetes mellitus includes: Hypoglycemia it is ca...
The overall average of the control Daphnia’s heart rate is 249.38 bpm. 0.01% caffeine’s average is 327.93 bpm, and the caffeine at 0.005% has an average of 268.90 bpm, both making the heart rate speed up. Ethanol had the opposite affect, 0.01% ethanol’s average heart rate for this experiment is 159.58 bpm and 0.005% ethanol had an average of 183.4 bpm. Caffeine has a positive percent change while ethanol has a negative percent change in the data chart. The percent change for 0.01% caffeine is 31.50%change, for 0.005% of caffeine it is 7.83% change and for ethanol 0.01% it is 36.01% change while 0.005% ethanol has a 26.47% change. The standard deviation for the treatments all relatively close. Caffeine 0.01% had a standard deviation of 49.77, 0.005% caffeine’s standard deviation is 58.95. The standard deviation for 0.01% ethanol is 54.19, ethanol 0.005 had a standard deviation of 49.47, and the control groups is 33.31. The p-tests show if and how significant the data
The purpose of this investigation is to test the effects of multiple sugar substances on the respiration of yeast. Most people think of yeast when they think of what makes bread rise, cheese, alcoholic beverages, or other food products. Another type of yeast can also cause yeast infections, an infection of the skin. Yeasts (Saccharomyces) are tiny, microscopic organisms with a thin membrane and are usually oval or circular-shaped. They are a type of single-celled fungi of the class Ascomycetes, capable of processing sugar into alcohol and carbon dioxide (CO2 ) ; this process is known as fermentation. Fermentation and the products are the main focus points for this experiment being that cellular respiration of yeasts happens via the process of fermentation, which creates by-products of alcohol and CO2. The level of CO2 produced by the yeasts will show how effective each sugar substance is in providing cellular energy for the yeasts.
The purpose of this experiment was to see how much the time spent baking in an oven would effect a cupcake. More specifically, how much it effects the rise. Also I wanted to see if I could find the perfect bake time where they tasted the best in my opinion. I was able to do that quite easily, with only a few problems.
In addition, each of the test subjects had high resting heart rate. On average, resting heart rate should be approximately
The data for my experiment showed that as time went by the heart rate increase followed by a major decrease known as a crash. A crash occurs when your heart rate increases so fast all at once that when the caffeine’s effect wares off the heart rate drops rapidly. Energy Drinks are known to give you energy, but part of the agreement that comes with consuming these types of drinks is being ready for the consequence. Some consequences are more severe than others. My hypothesis was proven to be correct. Your heart rate does increase over time due to the amount of caffeine the energy drink
Results: The experiments required the starting, ending, and total times of each run number. To keep the units for time similar, seconds were used. An example of how to convert minutes to seconds is: 2 "minutes" x "60 seconds" /"1 minute" ="120" "seconds" (+ number of seconds past the minute mark)
To make sure it is a fair test; the procedure is repeated a couple of
...executed was on the AstroTurf outside the school. This could have affected the subject’s performance and how the results were measured. To improve this, the experiment should have been carried out in a science lab on a treadmill so that the environment is constant and so that the heart rates are easier to measure. Thirdly, the temperature of when the experiment took place was about 10°C which may have affected the subject’s performance. If this experiment were recurrent then 5 subjects would do it inside (room temp. 21°C) using the treadmills and wearing the right clothing, and another 5 would do it outside to see if this factor did in fact affect the results and cause them not to be as accurate as it could be. Then we would be able to compare the two temperatures. Overall this experiment ran smoothly with some problems, which can be improved as I explained above.
We then put the stopwatch on and left them for half an hour. After we weighed each potato tube and recorded our results. We did the experiment twice. We did this to make sure our results were correct. Preliminary method: We did everything the same as in our other experiment except we
