The Effect Of Temperature And Music On The Retention Rate

- Discussion The test scores of the participants in the study did not vary enough to warrant a conclusion of the effects of temperature and music on the retention rates. There was a tendency for those in the warmer conditions to have a more positive attitude and, possibly because of this slightly improved mood, to score higher on the retention test (Appendix B Figures- 7&8). It is possible that because reading is commonly associated with warmth—cozy blanket, burning fireplace, hot chocolate, etc.—that participants preferred this environmental condition while reading a children’s story....   [tags: Temperature, Cold, Thermodynamics, Heat]

The Effect Of Temperature And Microwave Radiation On Enzymes

- The article talked about the effects that stresses, such as temperature and microwave radiation, have on enzymes, most importantly in the effect of denaturing enzymes. The purpose of the article was to examine if a certain type of charcoal, termed biochar, could stabilize soil enzymes after these had been under denaturing stress. Also, the biochar was used to determine if water concentrations could be maintained under the stresses already mentioned. The particular type of method that was used to determine how biochar would aid the enzymes was by placing soil in different vials with different concentrations of the biochar, ranging in concentrations of 0, 1, 5, and 10 percent....   [tags: Enzyme, Temperature, Microwave oven, Energy]

The Effect Of Temperature On Beetroot Membranes

- The effect of temperature on the beetroot membranes Aim of the research: The aim of this investigation is to determine what kind of effect will the increasing temperature have on the plasma membrane of a beetroot cell. Introduction The beetroot contains a red pigment that is kept in the cells by the membranes. If the membranes are damaged, the pigment “betalain” will leek out. The amount of pigment that leeks out can be assessed, as “betalain” will colour any water that surrounds the cell. If the water with the beetroot slices is heated at different temperatures, then will the temperature have any affect on the colour of the solution....   [tags: Molecular Biology]

The Effect Of Heat Transfer On Temperature

- 1.1 GENERAL BACKGROUND Heat transfer is by virtue thermal energy stored in temperature-dependent motion of particles. The exchange of kinetic energy of particles occurs through the boundary between two systems which are at different temperatures from each other or from their surroundings. Heat transfer constantly occurs from a region of high temperature to the region of lower temperature. Heat transfer changes the internal energy of both systems according to the Thermodynamics. The Second Law of Thermodynamics defines the concept of thermodynamic entropy....   [tags: Heat, Thermodynamics, Temperature, Heat transfer]

Procedure to Investigate the Effect of Temperature on Beetroot

- Aim: to investigate the effect of temperature on the cell membrane structure. Hypothesis: I predict that more concentration of betalains will be released as the temperature increases because the temperature will soften the cell vacuole and cell membrane allowing more betalains to pass through. Introduction: Beetroot contains red pigments called betalains, located within the cell vacuole. Normally the pigments cannot pass through the membranes but they can leak out when the beetroot is cooked. To function correctly a cell needs to be able to control transport across the partially permeable membrane....   [tags: Science Lab]

The Effect Of Temperature On The Temperature Operating Spectrum

- The temperature operating spectrum varies from 2 to 80 °C, although practically, in the study of biomolecules, a narrower range of temperatures is used (usually from 10 to 35 °C). During an experiment cells are filled with liquid, with the reference cell used as a reference that usually contains water and the second cell (sample cell) contains the sample. The temperature is set by the user and is maintained at the same level between the cells and the jacket by heaters (resistances). The whole system is based on the constant power that is supplied to the reference cell, which in turn enables or disables the heater on the sample cell and provides a baseline power signal, the DP (differential p...   [tags: Thermodynamics, Entropy, Internal energy]

The Effect of Temperature on the Rate of Enzyme Activity

- ... The first way is by helping the substrates to bind together. It is easier for substrates to react if they are closer together, thus bringing on the transition state. The second way is by repositioning them. Substrates do not travel in a particular direction and so if they are repositioned so that they collide, they will react. Another way to cause reactions is using an induced-fit model. This means that the enzyme changes its shape to better fit the substrate and make for a stronger bond. Finally stopping water molecules from getting through and disrupting the reactions will help binding occur....   [tags: biochemical analysis]

Scientific knowledge ==================== From previous experiments I have learnt several things about yeast and enzymes. I have learnt that an enzyme is a natural catalyst, (something that speeds up the experiment without altering the out come.) Yeast is a fungus that is used in fermentation this is because it respires anaerobically and aerobically, the anaerobic respiration is the use...   [tags: Papers]

The Effect of Temperature on the Permeability of Beetroot Membrane

- The Effect of Temperature on the Permeability of Beetroot Membrane Analysis The graph shows the colorimeter readings increase as the temperature increases, they increase by the most at higher temperatures. This is shown by a smooth curve. This means that the beetroot samples release more dye at higher temperatures. This is because higher temperatures cause the membrane structure to break down. The membrane structure: Membranes have two layers of molecules called phospolipids to make up their structure....   [tags: Papers]

Effect of Temperature on Rate of Reaction of Catalase

- Effect of Temperature on Rate of Reaction of Catalase Introduction This investigation was in an attempt to try to find out how varying the temperature can affect an enzyme. The enzyme used was catalase which breaks down Hydrogen Peroxide, this gives off water and oxygen as effervescence. This effervescence is what is used to measure the reaction rate of the catalase. The optimal heat for enzyme activity is proven to be 37oC as anything above this denatures the enzyme. Denaturing is where the heat energy of breaks down the di-sulphide, ionic and hydrogen bonds that hold the tertiary structure together, this in turn changes the shape of the active site and so halts...   [tags: Papers]

Lab Experiment: The Effect of Temperature and Respiration

- Introduction: Respiration commonly known as the inhalation and exhaling or breathing has a more little known definition. This is the definition that involves the cellular level of eukaryotic cells. Cellular respiration may best be described by the following equation: C6h1206+602-6CO2+6H20+36ATP. ATP that is the energy needed for a cell to function as part of cellular respiration. ATP is needed to power the cell processes. If cells are denied energy they will die.
