Observing Enzyme Activity Purpose: The purpose of this experiment was to test whether the pH affected the enzyme reaction rate. Hypothesis: If the enzyme is in a basic solution‚ then it will react faster because the enzyme (catalase) reacts better in basic solutions. Materials: 10 potato cubes (1 cm3) -Pipet Baking soda solution -50 ml glass beaker Bleach Water Lemon juice Vinegar 5 glass test tubes Drying rack Timer Graduated cylinder Hydrogen peroxide Procedure:

order to gain further insight on the research at hand. Discussion Initially‚ Hill & Barton (2005)‚ demonstrated how red increases contestant’s chance of winning. Their line of argument followed the aforementioned research; Cuthill et al.‚ 1977; Milinski & Bakker‚ 1990; Setchell & Wickings‚ 2005; Waitt et al.‚ 2003. Thus‚ Hill & Barton (2005) took on an evolutionary perspective‚ arguing how the influence of the colour red is involved in competitive interactions and emphasizing its importance in sports

show that music possesses properties that affect the growth rate of plants in different ways. These properties may be the wavelength of the music‚ its frequency or even its tempo. According to a study conducted by Margaret E. Collins and John E. K. Foreman‚ entitled The Effect of Sound on the growth rate of plants (2001)‚ plants growth is directly affected by sounds of varying frequencies. They observed that when plants are exposed to pure tones‚ it affects the growth of the plant. This was due to

The use of land and the resources that they contain has led to the alteration of land cover‚ affected the ecosystems where the lands are found (Kharel‚ 2010). The increased intensity of practices and processes like mining‚ housing development‚ logging and lumbering‚ agriculture relocation‚ etc. have given rise to a high rate of uncontrolled developments‚ resulting to environmental degradation‚ loss of wetlands‚ loss of agricultural

Music is promoted in all traditions for the well-being of the listener. The objective of this study was to analyze the emotional changes due to Indian music and their effects on the EEG. The two-dimensional emotion models and their effect on the brain were evaluated while listening to Indian raga. Asymmetrical alpha component energy was noticed in the frontal locations with the relative alpha component energy being lower at F3 and F7 positions when compared with F4 and F8 electrode position while

Enzyme Activity How does temperature affect enzyme activity? In this practical investigation‚ my aim is to discover how temperature will affect enzyme activity‚ by looking at the rate of reaction. I predict that the higher the temperature will be‚ the faster the reactions take place. However‚ I also think that there will be an optimum temperature‚ at which the reaction will work at its fastest; if the temperature goes beyond that‚ the reactions will stop altogether as the enzymes would have

How does longitude and latitude affect people? Latitude and Longitude both affect the weather and the temperature. The weather and temperature also affects us. The farther away from the equator the more extreme the weather is going to be. For latitude the closer you are to the equator the hotter it will be. The farther away you are from the equator the colder it will be. The region near the equator affects the most sun because of the shape of the Earth. The light also has to penetrate

and it can be problematic for them. Today‚ some countries have allowed the use of marijuana‚ for both medicinal and recreational uses. However‚ it is difficult to see the consequences of the legalization of cannabis. Since it is impossible to tell how many people used marijuana even before the legalization of the plant‚ it is therefore impossible to determine if this number has increased or not. Of course‚ this made cannabis easier to obtain‚ meaning that it can now be more harmful to people who

length of wire affects its resistance. Prediction (Hypothesis): I predict that the longer the wire the higher the resistance‚ and the shorter the wire the lower the resistance. Knowledge: Resistance is that property of electric components that turn electric energy into heat in opposing the passing of an electric current.It can be beneficial‚ as in electric heaters‚ or a pest‚ as in light bulbs‚ where the heat is produced alongside the light – we want maximum light and minimum heat
