November 20‚ 2013 Lab Report 1. Problem: To find the density of a Hershey chocolate bar. 2. Hypothesis: I think the chocolate bar will gradually decrease in density as it gets smaller. 3: Materials: 1 whole Hershey chocolate bar‚ ruler‚ triple balance beam‚ tray‚ calculator. 4. Procedure: First‚ find the mass‚ volume‚ and density of an entire Hershey Bar. Then‚ systematically‚ break off one section at a time to calculate the mass‚ volume‚ and density for 3/4‚ 1/2‚ and 1/4 of the

for the work you do. At the beginning of the movie‚ Chris Gardner is a medical equipment salesman and he invested his family’s savings in a portable device‚ which is a bone-density scanner. His work is carrying this bone density scanners demonstrate and sell to the doctors but unfortunately‚ hospital think that bone density scanners are luxuries and expensive and lead to this machines are not easy to sell. Even sometimes Chris Gardner not able to sell one in 2 months. As Chris Gardner tries to

cheese. Lactic acid bacteria(LAB)‚ a bacteria that can be found in the production of cheese‚ its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The characterisation of the strain illustrates how identification of strains differ using different methods‚ such as gram stain and 16s rRNA screening. After the characterisation‚ the stress gene isolation assist the further understanding of the gene on LAB be giving different stress

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

while U. coarctata‚ having a thick cuticle‚ tends towards osmoregulating over a range of salinities. This experiment is designed to test the hypothesis that P. lurcra is an osmoconformer and U. coarctata is an osmoregulator. The method used the density of extrcellular fluid (ECF) as a measure of ionic and osmotic concentration. All body fluids are more dense than water since they consist of water (SG=1) plus solutes. Increased solute concentration causes an

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

Does a company need a noble purpose to be successful in the long run? In my opinion yes. There are many factors that plan in on whether a company will be successful or not‚ but having a noble purpose‚ I believe is the most important of all of them. Without a company having a noble purpose many things can happen‚ employees quit‚ lose customers‚ leaders may start heading down an un-ethical path. A company having a purpose can prevent many of these possibilities from happening. When a company does
