The Cell Structure and function Abstract In this lab the structures of various cells were viewed through a compound microscope. The bacteria in yogurt was viewed a long with a slice of potato‚ and a thin skin of red onion. The potato was dyed with iodine while the red onion was dyed with methane blue. The students had to assemble the first three slides. Two more slides were provided these are the yeast and protozoa cells. Those two are also viewed with the same microscope

The Effect of pH on Enzymatic Reaction Rate Abstract Enzymes are affected by changes in pH. The most favorable pH value— the point where the enzyme is most active—is known as the optimum pH. This experiment was conducted to determine the effect of pH reaction rate on an enzyme‚ catalase‚ from yeast. The experimental results indicate that the catalase worked best at a neutral pH level of seven (7). Introduction An enzyme is a protein molecule that serves as a catalyst. “The basic function of

ABSTRACT 3 Idiots‚ in spite of being a comedy‚ it also carries a message about humanity and the rat race. This shows that the message in this particular movie has been the pull factor that attracts the audience to watch this movie. There are lots of positive messages contain in this movie that we can point out and relate with our reality life. The objective of this report is to analyze between chapter three that is perception and learning in organization; and chapter four that is workplace emotions

In the next step in aerobic respiration‚ each pyruvate‚ as produced by glycolysis in the cytosol‚ is normally converted to acetyl-CoA by pyruvate dehydrogenase in the mitochondria. During this process‚ electrons are transferred to NAD+‚ producing NADH‚ and a carbon is lost in the form of CO2 as a product. Acetyl-CoA then goes through another series of reactions in the TCA cycle‚ all of which also occurs in the mitochondria‚ to generate ATP and NADH through the complete oxidation of the molecule (generating

Abstract: Soil Manipulation to increase efficiency. The objective of this plant growth experiment would be to distinguish if potting soil could be manipulated in any certain way‚ to maximize or increase its overall efficiency. Our goal would be to determine what optimum combination of ingredients would best increase efficiency in soil productivity to equal the result of hydroponics (Cultivation of plants in nutrient solution rather than in soil). Through research our group came to the conclusion

ABSTRACT The effect of inorganic cofactor such as Magnesium to the rate of respiration of yeast was determined using Durham tube assembly with the substrate glucose. After thirty minutes‚ the test tube with the cofactor in the form of Magnesium sulphate MgSO4 showed the higher amount of carbon dioxide evolved which was measurable through volume and was one of the by- products of cellular respiration. This stated that the higher amount of CO2 evolved‚ the higher the rate of respiration. Thus‚ the

Introduction Chemical kinetics is the study of reaction rates. A reaction rate is the speed of the change in either reactants or products over a period of time. General kinetic rate equation is: Where [A] and [B] are the concentration of the species in the reaction. The variable k is the rate constant‚ which is a function of time and catalyst presence. The variables m and n are the order of reaction for their respective species concentration. The higher the value of the reaction order the

In this lab we are going to be observing the decomposition of piglets over a month’s time. There are theory questions that have been given to us before and after the lab. We look back at our original theory to see where we went wrong‚ and then correct it. The lab was disgusting‚ surprising‚ and very interesting. The first questioned to be answered is which piglet decomposes faster‚ a piglet that is in its natural state‚ that is burnt‚ that is buried‚ and that is buried in a wooden box? With

ABSTRACT This study examined continual student tardiness within an urban middle school in Karachi. The primary aim of the study was to improve the punctuality of identified middle school students by providing them with rewards and incentive on the observation of each decrease in their tardiness. In addition to it‚ it focused on facilitating and transforming the behavior of the parents and teachers towards student tardiness in the school. Action research design was applied and eight students were

Writing of Lab Reports __________________________________________________________________________ W hy should I bother writing lab reports in the correct way?” The Foundation Programme is designed to prepare you for undergraduate studies at UTAR which will require the writing of lab reports all years generally. At the end of your third year‚ you may have an opportunity to work on scientific projects which will culminate in an official scientific report. Depending on the quality of your report
