Based on the knowledge I gained from the blubber lab‚ I discovered how homeostasis is maintained by feedback loops in regards to blubber. A negative feedback loop is a process where change is prevented and a certain set point is kept. In this experiment‚ the negative feedback loop was the blubber preventing the changing temperature of the thermometer. Therefore‚ blubber is a method of homeostasis‚ because it prevents the ideal temperature of the thermometer from dropping. Our data shows this as well

Purpose Name Due Date Clothespin Lab / Muscle Fatigue What are the affects of anaerobic respiration on you muscles? Background Normally‚ muscles use oxygen through a process known as cellular/aerobic respiration to make energy (or ATP) from sugar (glucose). This process is very efficient and produces 38 ATPs for each molecule of glucose. Carbon dioxide and water are the results of this reaction. When muscles undergo rigorous exercise they require more oxygen to make ATP than the

Genetic transformation of Escherichia coli with pGLO (Adapted from: Biotechnology Explorer: Bacterial Transformation: The pGLO System. Instructors Guide. BIO-RAD). Objectives a. To understand one of the most commonly used techniques for introducing DNA into E. coli cells and its use in molecular cloning. b. To become familiar with the concept of using green fluorescent protein (GFP) as a molecular tag for studying gene expression in bacteria and other organisms.

The experimental membrane we used in this lab acted as a barrier in which only a small number of molecules can pass through. In this experiment we wanted to show the process of osmosis‚ in which water passes through the aforementioned barrier. Osmosis is critical to life because the process regulates

Electrostatic Lab What materials will you use? I will use the virtual lab and elements provided by the class What would you measure? I will measure the static electricity with a neutrally charged balloon What results do you expect? I expect that the balloons charges and sticks to the wall. What is the result are different? That would mean that there is a different way to charge the balloons than negative charge as using your hair. EXPERIMENT Bring together the balloons but not touching

Flame Test Laboratory Report Introduction The purpose of this lab is to observe and identify metallic ions‚ using flame tests. The traditional flame test originated when Robert Bunsen invented the Bunsen burner to test two new alkali metals he and his partner had discovered. “A flame test is an analytic procedure used in chemistry to detect the presence of certain elements‚ primarily metal ions‚ based on each element’s characteristic emission spectrum” (Flame Test 1). Using this test‚ an element

An Experiment to Test the Effect of Temperature on the Rate of Photosynthesis in Green Algae Background Photosynthesis is an amazing process where plants are able to create their own food as well as oxygen using sunlight‚ carbon dioxide (co2)‚ and water. The part of the plant responsible for photosynthesis is the enzymes in the chlorophyll (structures that carry out photosynthesis located in leaves). Photosynthesis is the process of creating glucose. Water + Carbon Dioxide + Sunlight = Glucose

Lab Report Janice Chisholm SCI207: Dependence of Man on the Environment Instructor: Lee Ott April 28‚ 2013 1. What patterns do you observe on the information table 4? While observing the information in table 4‚ it appears that the number of fish changes from time to time and the oxygen increases and / or decreases when this occurs. 2. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water?

Calorimetry Lab Problem: Which foods have the most calories? Hypothesis: If we burn the food then the heating released will be measured as calories because the energy stored inside is released as heat and light. Parts of the experiment Control Group-water Experimental Group- different foods Independent variable- Type of food Dependent Variable- temperature of water Controlled variables- water temperature of unheated water Materials Stirring Rod‚ Beaker‚ ring clamp‚ evaporating disk‚
