Title: Effect of Polarity In Diffusion Of Molecules Across Cellular Membrane Abstract: Cell membranes play an important role in regulating what goes in and out of the cell. Diffusion‚ the process of movement of substances across the cell membrane from higher concentrations to areas of lower concentration‚ plays an active role in the transport and the regulation through cellular membrane. Sometimes‚ there are cases when cells are placed in hypotonic solutions and substances will diffuse through the

Carbohydrates that cannot be broken down to lower molecular weig ht carbohydrates by hydrolysis are monosaccharides‚ a term that indicates that they are the monomeric building units of the olig o- and polysaccharides. Monosaccharides are commonly referred to simply as sug ars. They can be joined together to form larger structures‚ namely‚ oligosaccharides and polysaccharides that can be converted into monosaccharides by hydrolysis. They vary in the number of carbon atomspresent in their structure. Table 1

THE INTRODUCTION TO SOAP MANUFACTURE BY W. H. SIMMONS‚ B.Sc. (Lond.)‚ F.C.S. AND H. A. APPLETON It has been said that the use of soap is a gauge of the civilisation of a nation‚ but though this may perhaps be in a great measure correct at the present day‚ the use of soap has not always been co-existent with civilisation‚ for according to Pliny (Nat. Hist.‚ xxviii.‚ 12‚ 51) soap was first introduced into Rome from Germany‚ having been discovered by the Gauls‚ who used the product obtained

17.1 Genes specify proteins via transcription and translation * George Beadle and Edward Tatum worked together with mutated (Neurospora crass) bread mold to figure out that they were missing a specific enzyme (gene) that catalyzed and synthesized a pathway required. They concluded that they were missing that enzyme because it was lacking the amino acid that coded for the enzyme‚ thus was mutated and incapable of growing. Led to the one enzyme-one gene hypothesis. The Products of Gene Expression:
