    results indicate that the presence of iron increases the rate of the peroxidase’s activity‚ judging from the increase in absorbance with increasing amount of iron. This result supports our hypothesis that the iron acts as a cofactor in peroxidase’s activity and results in the faster rate of the reaction. Also‚ we assumed that the more we put iron in the solutions‚ the faster the rate is. This assumption is also supported by the results that higher concentration of iron cofactors shows the higher absorbance

    Introduction In this lab we had to design a system that would test if changing the mass‚ angle of release and length would have any effect on the period of a pendulum. Hypothesis As the length‚ mass and angle of release change‚ the period (T) will change for each one of these factors.

    Biosphere Lab Report A biosphere can be defined a lot of different ways. Our interpretation of a biosphere is the area in which life can be contained within. In the case of the earth‚ it means as high as a bird can fly and as deep as fish can swim in the ocean. A biosphere is a closed system that has a constant flow of energy between the organisms living within it and it needs nothing outside of itself but sunlight to continue to be sustained. At the University of Arizona‚ they attempted to build

    LAB REPORT HYPOTHESIS 1: Plants transpire the most when the environment has light and less humidity JUSTIFICATION: Water evaporates more readily because light stimulates the opening of the stomata and photosynthesis would occur. HYPOTHESIS 2: Transpiration would occur the second most when there’s light and lots of humidity. JUSTIFICATION: The light would allow photosynthesis to occur and the stomata to open but little if any diffusion of water out the leaf would occur. HYPOTHESIS 3:

    Enzyme Lab Report Introduction The objective of this experiment was to determine if changes in pH or temperature affected the activity of enzymes‚ specifically the enzyme sucrase. Enzymes are protein molecules that act as biological catalysts to increase the speed of the reaction or to lower the activation energy of that reaction. However‚ the activity of an enzyme can be affected by physical factors such as pH and temperature because these factors alter the structure of the enzyme (Freeman‚ 2011)

    Results and discussion The aqueous solubility of midazolam is a function of both the imidazobenzodiazepine ring opening‚ which is a fully reversible process‚ and the ionization of the drug molecule play an important role in the supramolecular complexation with water-soluble cyclodextrins (Loftsson et al.‚ 2001). Therefore‚ the total charges were assessed from the acid dissociation constant determined for different forms of midazolam as depicted in Figure 1. First‚ predicted negative decimal logarithm

    SEPERATION OF A MIXTURE Purpose: The purpose of this lab is to find out how components of a mixture can be separated and analyzed. Procedure: The procedure for this lab report is as follows: 1. Mixture is taken‚ and has to be measured in order to meet the requirements of 2-3g. 2. The mass of the tray is measured and then the scale is zeroed out and the mixture is added to find out the mass of the original mixture. 3. Next‚ find the mass of the 250mL beaker‚ zero out the scale

    technique is: Number Moles Concentrated Solution = Number Moles Dilute Solution. An instrument called a spectrophotometer detects the amount of light that passes through the sample and the percent transmittance can be recorded from the meter. In the lab‚ multiple homogeneous solutions are made. There was not a way to determine the differences in concentrations‚ but the Spec 20 made it possible to measure the difference. The Beer-Lambert Law is a graph used to record

    Copper is one of the few metals that have been mined for more than 100 decades globally. According to M.G.C Wilson (1989) copper has been mined since the early 3000 BC in Cyprus. In the ancient times copper was used for making tools‚ weapons‚ ornaments and many household utensils. Copper is the third most widely used metal after aluminium (Al) and iron (Fe) because of its high durability (Doebrich et.al‚2009). In the Southern African region copper has been extracted by the early inhabitants long
