Title: Diffusion throughout the membranes Lab Partner(s): Alexis Clouting Date: 2/15/15 Abstract: In the content of the Module 2 we learned about Diffusion across cell membranes. We touched on the different types of cells and their functions. How things are transported in and out of cells. Learning about isotonic‚ hypertonic and even hypotonic solution. This is not my first time touching on this subject in my nursing career and I learned a way to remember what happens in the different solutions

think the urea was not able to diffuse through 20 MWCO? How well did the results compare with your predictions? The urea was not able to diffuse through the 20 MWCO because the membrane pores are too small and the urea molecules are large. The molecular weight of Urea is 60.07 g/mol which is too large thus the molecules were not able to pass through the pores of the 20 MWCO. The results that I obtained from the experiment agreed with these predictions because urea was no able to diffuse through

Micheal Pollan’s "Playing God in the Garden" addresses the many unseen aspects of farming and the technologies that are being designed to make planting effortless and safe. Pollan discusses how New Leaf (the plant company which has created the new biotechnological seeds) advertises a safer and less expensive way of farming‚ while concealing the harmful aspects of its product. The idea of genetically altering organisms has always made me uncomfortable. When I began to read this article‚ I assumed

Introduction: With the execution of this experiment‚ we began to go deeper into the Cell and Molecular Biology course. The main focus of the experiment would be how the Restriction Endonucleases cleave the strands of DNA. For this experiment‚ pBR322 was the specimen to use. Restriction Endonucleases work by cleaving the sugar phosphate backbone of specific DNA sites. Restriction enzymes that have been isolated from bacteria have a defensive role. This idea is illustrated when an attacking foreign

vector was used to clone the individual PCR products which then transformed into E. coli. Catalytically active domains were studied by analyzing deduced amino acid sequences of genes. SDS-PAGE analysis was carried out to estimate the molecular weights of proteins. Molecular weights of peh‚ celB and celC products were found to be 41.5 kDa‚ 29.5 kDa and 40 kDa‚ respectively. Agar diffusion assays were performed to qualitatively determine the activities of polygalacturonase and cellulase of the cloned

Guide to Profitable Investment in Pig Farming By Obinna Chima Before Miss Oyinlade Adetutu graduated from the University of Ibadan in 2005‚ she had already made up her mind not to go into the already saturated labour market. As a student of Agricultural Science‚ she had vowed to stick to her profession by investing in the sector in order to tap from the benefits that abound in it. Though she specialised in fisheries‚ she got to know about pig farming and became attracted to it because of the
