2.3 Results 2.3.1 The Effect of O. lybicus Population on Palms Temperature Over Time Temperature differences between different O. lybicus population levels were not significant in leaves and fronds (P > 0.05). However‚ high significance difference in temperature were occurred over time (P < 0.001) in both parts Figure 1 and 2. The temperature at the highest population (1000 insects) were the highest at the first three weeks‚ before it starts declining gradually (figures 14-15). Chlorophyll measurements

for the effects of temperature on catalase activity. Introduction: Enzymes are proteins that act as catalysts and help complex reactions to occur everywhere in life. Enzymes affect a chemical reaction by acting as a catalyst‚ which is to say‚ it speeds up the reaction. However‚ extreme ph and temperature hinders enzyme function. Optimal activity of an enzyme is the optimal environment that an enzyme requires to function‚ which means having the optimum ph and temperature to catalyze a reaction

Chapter 15 & 16: Temperature‚ Heat & Heat Transfer Temperature is a measure of the average (not total) translational kinetic energy. ●ex: there is 2x as much total molecular kinetic energy in a 2L of boiling water than one‚ but the temp of the two volumes are the same (average of translational kinetic energy per molecule is the same in each → Internal Energy- the total of all molecular energies: kinetic+potential (SAME TEMP) ● Ex: apply a flame to 1L h2o for a certain time and its temp rises

Jars were filled with a 100ml of federalized water‚ and a mark at the 100ml was made as indication to ensure the correct amount of water was given if the jars needed to be topped up. With a Q-tip‚ 10 green Lemna leaves with growing roots were placed into each of the ten designated jars. The five room temperature jars were placed into

investigate the effect of temperature on the enzyme catalase. The original research question was exploring the effect temperature would have on a yeast catalase reacting with hydrogen peroxide (H2O2). To address the latter question a series of experiments were conducted. The various temperatures experimented with were as follows: 22 degrees Celsius (room temperature)‚ 0 degrees Celsius (freezing)‚ 100 degrees Celsius (boiling)‚ and 37 degrees Celsius. Along with variations in temperature‚ the experiment involved

Premium Temperature Heat transfer Thermoregulation
Temperature is one of the weather elements and measures the degree of hotness and coldness in a place. The temperature of a place is affected by a number of factors such as latitudinal location‚ seasonal variations‚ albedo of the place‚ contrasts between land and sea and elevation. Latitudinal location has the strongest influence on the climatic conditions on a macro/global scale. The rest of the factors then serves to modify these influences and are secondary‚ operating at a smaller scale. Latitude

experiment was to determine the effect of caffeine on resting body temperature. This has to do with homeostasis‚ which is the maintenance of equilibrium. In other words‚ it is a stable body state. Homeostasis refers to the process of keeping the internal body environment in a steady state‚ when the external environment is changed (Homeostasis 2). Humans are warm-blooded creatures that generate body heat internally and maintain body temperatures at a fairly constant level – about 98.6oF (Chiras 3). In this
