experiment was quick and easy. Ways to improve the experiment A in which the experiment could be improved is that the dialysis tubing could have came already cut into the 25cm. Conclusion In conclusion to this‚ the results support the hypothesis. Which means as the percentage of sucrose increase‚ the weight of the dialysis bag had also increased.

Consitution of 1962 Background On 7 Oct 1958 the military assumed power in Pakistan under the leadership of general Ayub Khan who was the Commander in Chief at that time. The military abrogated the Constitution and the federal and provincial cabinets were abolished. The national and provincial assemblies were also abolished and martial law was imposed in Pakistan.Ayub Khan became the chief martial law administrator and in this way the 1st military govt came into existence in Pakistan.

the highest amount rise‚ which will show us the optimal color of light for photosynthesis. These different colors of light included blue‚ red‚ green‚ fluorescent‚ regular light‚ and classroom light. The classroom light was our control cup during the lab. Before we conducted our experiment‚ the class learned about the photosynthetic process of‚ not only spinach discs‚ but plants in general. As I did more research on photosynthesis‚ the Calvin Cycle‚ wavelengths and pigments required for a proper equation

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.

Danny Fish 10/9/11 Chemical Testing To identify An Unknown The hypothesis tested was that depending on the solution presented‚ which would test positive for one of the following‚ proteins‚ carbohydrates‚ or lipids through use of chemical testing. (Sudan IV‚ Benedicts’ Solution‚ Iodine‚ Biuret’s) . In order to gain more information for the hypothesis‚ one must know how to test for said macromolecule. Each of the above stated molecules has their own individual solution that will in turn identify

Controlled variable: How far apart i put the chairs and also where we tape the tape. Hypothesis - if we tape one angel hair‚ one fetuchini‚ and one spaghetti noodle then the fettuchini noodle will hold the most pennies. Materials - a 14 ounce plastic cup‚ two three foot tall stools‚ seventy pennies‚ 7 inches of fishing line‚ three angel

ABSTRACT: This lab allows us to observe the conversion of hydrogen peroxide (H2O2) into water and oxygen gas. An enzyme known as catalase facilitates this decomposition reaction. The catalase enzyme acts as catalysis‚ helping lower the energy needed to activate the reaction while the enzyme itself is not affected. Catalase is a digestive enzyme used to break down hydrogen peroxide‚ which is a normal byproduct of cellular respiration. The reaction could take place without the help of catalase‚ but

Through this process‚ they are considered very unique because they are not altered or consumed within the reaction (Lab Manual 3 pg. 1). This is why enzymes are considered biological catalysts. They also do not alter the equilibrium of a chemical reaction nor the amount of free energy that is released (Lab Manual 3 pg

enzyme. The hypothesis was that alkaline phosphatase activity will be critically affected by pH effects. The hypothesis was valid because the data shows that the pH values for the acidic‚ basic‚ and neutral tubes increased over time‚ absorbing at similar rates. The basic tube had the highest rate of absorbance while the acid tube had the lowest rate of absorbance. In the following experiment‚ the effects of varying enzyme concentrations on the catalytic rate of ALP were tested. The hypothesis was that
