between the rate of reaction and the surface area. The larger the surface are‚ the faster the rate of reaction seems to be. However‚ although the grain with the largest surface area (the smallest grain) reached the highest point within the shortest amount of time‚ its end result was still lower then the medium sized grain. The explanation for this result is relatively easy. The rate of a chemical reaction can be increased by increasing the size of the surface area to volume ratio of the solid reactant

growth‚ more chemical activity will have to happen and the rate of metabolism will also increase‚ which means that more substances have to be taken in and to also be removed. This is where the surface area to volume ratio comes into place; the reason why this ratio is so important is because the surface area of a cell essentially affects the rate of the transferring of useful substances (through diffusion and osmosis etc.) in and out of the organism. On the other hand‚ the total volume of the organism

by experimenting with model “cells.” In this experiment‚ you will use agar cubes to which the indicator phenolphthalein has been added. Phenolphthalein is an acid/base indicator that turns pink in the presence of a base such as NaOH. Thus the surface of the agar cubes will turn pink immediately when put into a NaOH solution. The NaOH will continue to diffuse through the cube and gradually turn the inside of the cube pink. The guiding question for this lab is thus: What determines the efficiency

must divide through mitosis. Cell division happens after the cell is big enough so the daughter cells will be replicated without any flaws. The regulation and amount of materials that can enter and leave the cell is based on how large the cells surface area is. The rate of movement is also determined by the volume of the cell. Many factors like the decline of food and temperature fluctuations can cause the cell to stop dividing. Materials: Plastic Spoon 2 Blocks of agar phenolphthalein Beaker Dissecting

and the time taken for a substance to diffuse to its centre. Hypotheses- Part A) The 5x5x2.5mm block will turn clear first as the Surface area to volume ratio is high and the 10x10x10mm block will take the longest to completely diffuse the Acid to its centre. Part B) The flat‚ rectangular block will be the first to completely turn clear due to its high Surface Area/Volume Ratio. When measured‚ the cubic‚ rectangular block will have a significantly higher percentage of diffusion than the sphere

Abandonment and Neglect in Gorazde. In his “Safe Area Gorazde” Joe Sacco describes his experience visiting a Muslim enclave during the Bosnian War of 1991-1995. Tragically‚ this work is based on testimonies of residents of Gorazde‚ allegedly a UN-protected area where Bosnian Muslims are able to take refuge to avoid the ethnic cleansing perpetrated by the Serbian army. Gorazde is anything but protected which Sacco demonstrates throughout the book by ridiculing the UN and the US who are able to and
