Osmosis is a passive movement of water through a selectively permeable membrane moves from an area of higher concentration to an area of lower concentration. In this lab‚ we can determine the direction of diffusion of small molecules by measuring the diffusion of small molecules through dialysis tubing. This tubing acts as a selectively permeable membrane‚ and allow to pass larger molecules slowly. Introduction: Cells have kinetic energy and it causes the molecules of the cell to move around

Experimental Investigation and Analysis of Mercerized and Citric Acid Surface Treated Bamboo Fiber Reinforced Composite Abstract: Mercerization or NaOH fiber surface treatment is one of the most popular surface treatment processes to make the natural fibers such as bamboo fibers compatible for use as reinforcing material in composites. But NaOH being a chemical is hazardous and polluting to the nature. This paper explores the possibility of use of naturally derived citric acid for bamboo fiber

cellular respiration to produce ATP. This process takes place in chloroplasts‚ which is a plastid that contains chlorophyll and involves two interlinked reactions‚ which are light dependent reactions and light independent reactions. Throughout our lab experiment‚ we focused on the affect access of light has on carbon dioxide during photosynthesis. Carbon dioxide levels decrease as oxygen levels increase and glucose is produced when light dependent reactions occur. Light energy is absorbed by photo

Book of Esther Review 1. (Source Sheet 1‚ #5) For the first time‚ there are two major Jewish communities: one in Persia and one in Eretz Yisrael. There is a tension between the two communities. The community in Persia is assimilated and they were high up in status. The two communities do not mention one another; there is no mention of Shushan in any of the books of the people who lived in EY. In Persia‚ the Jews were very assimilated - the Jews intermarried and were economically very well off

G. Y. S. Period: 6 09/11/12 Osmosis Lab I. Objective: The purpose of this lab is to put the solutions in chronological order from least to most molarity. If the solutions are hypertonic then‚ the water will go in and the order of the substances will be C‚ D‚ A‚ B‚ E. II. Materials and Methods: See attached page. Results: Table 1.1 III. Table 1.1 | Initial | Final | % Change | A | 11.4 | 11.86 | 4.03% | B | 11.67 | 15.33 | 33.68% | C | 10.84 | 11.86 | 9.4% | D | 12.02 |

Unlike most coefficients in Physics‚ friction behaves differently depending on whether the object is at rest or at motion.

functional group‚ and fatty acid. Triglycerides can vary in size and structure depending on the fatty acid attached. Glycerol is theoretically three ester bonds. In the experiment the ester bonds are broken down through a process called saponification. The product of this reaction is soap. An alcohol and carboxylic acid are also produced when an ester bond is broken. While under basic conditions the negative carboxylic acid and positive ions produce a Carboxylate salt of the fatty acid. Therefore
