Based on the prompt above‚ “You are going to test your body’s ability to maintain homeostasis. You will test this by monitoring a person in your group’s breathing rate‚ heart rate‚ and qualitative observations” we devised a hypothesis which states that if a person exercises‚ his/her heart rate‚ breathing rate and sweat (qualitative observation) will increase in order for our bodies to maintain homeostasis and control our bodily functions. Based on our experiment we found that in Trial 1 the heart

The Catalase Lab Stephen Human Anatomy & Physiology 9/30/12 Problem- How do different environments affect the reactivity of catalase? Hypothesis- If more catalase is added then more oxygen (kPa) will be produced in a faster rate because there is more catalase to react upon. If less catalase is added then less oxygen (kPa) will be produced in a slower rate because there is less catalase to react upon. Variable- Independent- Amount of Catalase (Filter Paper) Dependent- Amount of

RER of 0.7 means that carbohydrates are being used for fuel‚ and a ratio of 1.0 means that only fatty acids are being used for fuel; of course‚ values can fall between. Methods: To observe the effects of prolonged exercise on the metabolic system the lab subject needed to walk on the treadmill at a rate that kept his heart rate at 60% of his maximum. The

Enzyme Lab Report Introduction: Enzymes are proteins that enable chemical reactions. In the enzyme lab‚ the effects of concentration‚ temperature and pH on the functionality of the enzyme catalase. The enzyme lab was also about measuring reactions by capturing the oxygen that was generated by the reaction. Materials and Methods: Experiment 1‚ 2‚ & 3 Experiment 1 examined the effects of concentration on catalase activity. Experiment 2 examined the effects of concentration in temperature

Formal Scientific Lab Report Osmosis Katy Hunter 10-26-2012 Abstract: The objectives of this lab was to be able to create models of cells with the dialysis tubing to show us how the plasma membrane is selectively permeable‚ to study the effects of osmosis on a model cell‚ and to foresee the effect of solute concentration on osmosis. In order to achieve these objectives‚ we had to fill the dialysis tubing with either water‚ or different amounts of sucrose. We then tied off the tubes and put

Lab Report Microbiology Introduction Bacteria can be found almost anywhere. For human life‚ some help us‚ some hurt us‚ and others are neutral. It is now known that good bacteria‚ or normal microflora‚ can reach 1014 microbial cells. This is far more than the 1013 cells that make up the human body (Tannock‚ 1995). The total number of bacteria on Earth is estimated to be around 4-6 x 1030 (Horner-Devine‚ 2004). It is important to know the extent of bacteria‚ how they live‚ and how they are

Genetics of Drosophila Lab Report: The test of heredity in fruit flies In my testings with breeding the fruit flies‚ I learned that the purpose of breeding them was to test how genetics pass from generation to generation‚ also known as heredity. We attempted to breed the flies and get them as close to a 9:3:3:1 ratio as possible. This would lead to an acceptable trait ratio. My hypothesis was that if we were to breed the flies in a stable environment‚ the most common fly (or the fly with the highest

Equipment Calibration is defined as the act of adjusting and evaluating the precision and accuracy of measured equipment. It allows the user to get an accurate and precise reading of measurements to its actual true value. However‚ in order for the experiment to be effective is must consist of validity‚ reliability‚ and objectivity. Validity is defined as the ability of a test to measure what it claims to measure. Reliability is the consistency of test results and objectivity is defined as a test

For this lab‚ the expected outcomes are that when the heart rate and blood pressure are measured‚ both will increase when the heart has to pump against gravity‚ after exercise the heart rate will increase then return to normal‚ and as the subject inhales‚ it will be lower than when they exhale. Methods For this lab report‚ the laboratory manual (2009) was used for all labs. While completing lab five‚ electrodes were hooked up to the subject. After calibration for this lab‚
