had its roots in the work of two mathematicians‚ Paul Erdos and Alfred Renyi. Their work suggested that systems such as communications could be effectively modelled by connecting nodes with randomly placed links. Their simple approach revitalised graph theory and led to the emergence of the field of random networks. An important prediction of random network theory is regardless of the random placement of links most nodes will still have approximately the same number of links. In fact‚ in a random

In Graph 1‚ each line of color represents a different level of pH added to the solution. When pH 9 was added‚ it produced the highest rate of reaction (the most oxygen was produced)‚ whereas when the more acidic pH 5 was added‚ the rate of reaction was much slower‚ and less efficient. The higher the oxygen evolved (gas produced)‚ the more reactions were being produced/higher rate of reaction. Different types of enzymes’ reaction proportions differ based on the pH being added. For example‚ intestinal

Charts and graph are images that present data symbolically. They are used to present information and numerical data in a simple‚ compact format. This paper will focus on three types of charts and/or graphs which are: pie charts‚ bar graphs‚ and histograms. What types of data there are and how the data was collected is important for the reader to understand.. According to Bennett‚ Briggs‚ and Triola (2003) there are two types of data. They are: *Qualitative data- Data consisting of values that describe

After thanksgiving dinner that year I became interested in figuring out how the using the same recipes the outcome could be so different. Background Information: Osmosis is the of a solvent across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration. The water being the solvent can move across the membrane but the salt

Ilya Zaihrayeu http://www.dit.unitn.it/~ilya/os.htm Deadlock Prerequisites Deadlock can arise if four conditions hold simultaneously: Mutual exclusion: only one process at a time can use a resource. If another process requests that resource‚ the requesting process is delayed until the resource is released; Hold and wait: a process holding at least one resource is waiting to acquire additional resources

amount of sucrose concentrations. The higher molarity concentrations increased the movement of water to balance out the inside of the tube and the beaker. The greater amount of concentration gradient‚ in each tube‚ increased the rate of osmosis. This rate of osmosis is due to the net movement of water from an area of low concentration to an area of high concentration. Because the tubes had different concentrations‚ certain tubes gained more mass than others. Solution A had 0.6 molarity which increased

Introduction: Diffusion and osmosis are passive processes of transport. Passive transport involves no disbursement of energy by the cell. Diffusion movement is from high concentration to low concentration‚ which the driving force for this type of movement is kinetic energy particles themselves. Which crystal (Methylene blue‚ solid or Potassium Permanganate KMnO4-purple) will move further than the other due to the driving force (kinetic energy)? My prediction is that Potassium Permanganate KMnO4-

LINEWEAVER-BURK PLOT A graph of the double reciprocal equation is also called a Lineweaver-Burk‚ 1/Vo vs 1/[S]. The y intercept is 1/VMAX; the x-intercept is 1/ KM; and the slope is KM/VMAX. Lineweaver Burk graphs are particularly useful for analyzing how enzyme kinematics change in the presence of inhibitors‚ competitive‚ noncompetitive‚ or a mixture of the two. There are three reversible inhibitors: competitive

or volume of the plant cells does not change‚ means there is no net loss or gain of water. Introduction This study shares the results of an effort to understand diffusion and osmosis in general. It focused more into osmosis in plants cell‚ and how to indirectly measure osmolarity in potato tuber tissue. Osmosis is the diffusion specifically of water across a membrane. Diffusion occurs when certain substance‚ such as an ion‚ is more concentrated on one side of membrane. If the membrane allows
