    butterflies need to regulate their body temperatures through thermoregulation. There are two types of ways to regulate body temperature. The first one is ectothermy. Ectothermic animals‚ or cold-blooded animals‚ rely on outside sources to heat or cool themselves. Cold-blooded animals can lie under the hot sun to heat themselves up and prepare for flight or to move around. However‚ if there is no source of heat‚ they are not able to raise their body temperature to the correct level for movement. Butterflies

    The effect of temperature on the cell membranes of beetroot cells and amount of pigment released. Apparatus • Corer size 4 • White tile • A Beetroot • Automatic Water Bath • Segregated knife • A thermometer • Stopwatch Method: • First take the white tile and the corer. Then collect a cylinder of beetroot by pushing the corer into the beetroot and withdrawing it. The cylinder remains inside the corer- so push it out with the end of a pencil. • Collect 3 cylinders

    THE EFFECT OF TEMPERATURE ON CATALASE RESEARCH QUESTION: What is the effect of various temperatures‚ 0°C‚ room temperature‚ 37°C‚ 50°C‚ 60°C‚ on the number of oxygen gas bubbles liberated‚ in a decomposition reaction between the enzyme Catalase‚ obtained from crushed mung beans‚ and 2% of the substrate Hydrogen Peroxide? INTRODUCTION: Enzymes are biological catalysts that increase the rate of chemical reactions without they themselves being involved in the reaction itself. Enzymes are proteins

    Process of Diffusion and its importance in living organisms Diffusion is the movement of molecules or ions down a concentration gradient i.e. from an area of high concentration to an area of low concentration. For a diffusion system to be efficient‚ it should have a large surface area so that high amount of substances can be exchanged at a time. It should also have a thin membrane and a continuous supply of substances‚ as a thin membrane means that the diffusion pathway would be short‚ and the continuous

    Perform at least one exercise for each major muscle group on a stability ball. On another day‚ perform the same exercises in a stationary position (i.e.‚ not on a stability ball.) Report the following. List the exercises you performed. Were you able to use the same weight on the stability ball? If not‚ why do you think you could not use as much resistance? What populations would benefit from stability ball training? Are there certain individuals who should not use a stability ball? How will this

    the rate of diffusion through agar jelly. Hypothesis The diffusion of mythelin blue is directly proportional to its concentration‚ hence as the concentration increases; the rate of diffusion increases too. Controlled Variables Time time was kept constant while testing the diffusion spread of mythelin blue with each concentration. Temperature the experiment was undertaken in room temperature as change in temperature can affect the rate of diffusion‚ as a higher/lower temperature would mean

    Effect of Temperature on Enzymes ~Abstract~ In this experiment the effect of different types of temperatures on enzyme activity was examined. The temperature baths that were used to test the difference in enzyme activity on fresh liver were; 4 °C‚ room temperature which was 22°C‚ body temperature which is 37°C‚ and 77°C. The total time of each trial was 2 and a half minute‚ 1 minute for the H2O2 to acclimatize to the temperature‚ 1 and a half minutes for the reaction to occur. Catalase causes Hydrogen

    Peroxidase Enzyme & Temperature Abstract:  In this lab we tested the effect temperature has on the rate of enzyme activity. The way we figured this out was by taking four different temperatures and testing the different absorbance levels they produced every 20 seconds for two minutes straight using a spectrophotometer. The important part of this experiment was the temperature the enzyme concentration was made at. What we got from the experiment was at lower temperature we got very low numbers

    RESULTS 28⁰C was the optimal temperature. 28⁰C had the maximum rate of reaction for the class data and results provided by this experiment; the results were represented graphically in graph 1 and graph 2. The reason for having 2 tables and graphs is because 28⁰C was done twice. Data for 28⁰C was collected in this experiment and it was collected again by peers in the classroom. Results are identical because all temperatures except 28⁰C was collected once from peers. Based on the results from the
