Abstract The experiment aims to observe if simpler substrates makes the rate of cellular respiration faster. Using yeast‚ smith fermentation tubes and different substrates namely‚ starch‚ lactose‚ sucrose‚ glucose and fructose‚ which are from different kinds of carbohydrates‚ ranging from the simplest sugars glucose and fructose to the polysaccharide starch and water as the control‚ the hypothesis was tested. With the span of thirty minutes with five-minute intervals‚ the height of carbon dioxide

Environmental Variables and their effect on Horseradish Peroxidase Abstract There are several factors that can affect the rate of reaction of peroxidase such as temperature‚ pH‚ concentration of peroxidase present and whether or not it has been boiled. Our experimental data demonstrated that peroxidase activity peaked between 23 degrees Celsius and 32 degrees Celsius. We found the pH to be 7 for optimal activity. As far as the concentration is concerned our results showed that as the concentration

When performing this experiment make sure all materials are present this includes: Blood Pressure Probe‚ a Sphygmomanometer‚ computer with Logger Pro software‚ Stethoscope‚ Logger Pro cables‚ and a timer if you so chose. Using the Blood Pressure Probes‚ Logger Pro cable‚ and the software you are ready to begin the experiment. Have a scary video pulled up from youtube that is within the time limit of 0-120 seconds. It would be wise to have the video around 60 seconds because that is the time frame

I choose this experiment because i like doing stuff( projects‚ experiments.) in sports. I think this is a good experiment is a really fun and it falls good in the topic. I also chose this experiment because i think it’s really easy to do by yourself and i have all the materials to conduct it. i also chose this experiment because i’m kind of like an expert in this topic because i have been in football for like 3 years so i think i know alot about the balls grip and how it affects the length. I think

HYPOTHESIS - 1923 Haldane & Oparin propose hypothesis that life originated as simple molecules followed by cells - conduct simple experiments that show that organic compounds can form cell-like structures 3. EXPERIMENTATION - 1953 Urey and Miller collaborate effectively to design an experiment/model to simulate conditions on early Earth and test the hypothesis that life molecules could originate on Earth 4. RESULTS - Urey and Miller results confirm that simple

I have come up with an experiment to test the 3 variables to figure out what treatments if any will work the best. My hypothesis is that all 3 of the suggestive treatments when done before flying on an airplane‚ will reduce the effects of jet lag. Experiment: A commercial airplane traveling from New York City to Los Angles non –stop will be selected at random. All passengers will be randomly

In my experiment of breaking the norm‚ I did two different things. in one of my “experiments” I would hold doors anywhere I where for the people that were behind me and wait for a response‚ when the person was educated enough to say thank you I would smile and let it go. When the opposite happened‚ whenever the person behind me did not say thank you I would compliment myself. I would thank myself for holding the door instead. The first time I conducted this specific experiment I was at

In the Milgram experiment‚ a man picks random people to participate in an experiment. They believe that they are helping discover the roles of punishment on behavior. Although‚ this is not true. The participants themselves are the ones being analyzed. The experiment is to discover how far someone would obey an instruction of harming another person‚ despite personal conflict. The participant and an actor are places in a room and “get to choose” their roles of either teacher or learner‚ although the
