X – 9l August 15‚ 2012 ABSTRACT The effect of molecular weight on the rate of diffusion was assessed using agar-water gel test. The agar-water gel set up was composed of a petri dish of agar-water gel containing three wells. Drops of potassium permanganate (KMnO4)‚ potassium dichromate (K2Cr2O7) and methylene blue(C16H18N3SCl) were simultaneously introduced to each well. Methylene blue

You just reviewed type of carbohydrates. Glucose is a simple sugar called a monosaccharide ‚ whereas starch contains compound carbon chains and is a polysaccharide . 5. Polysaccharides are formed by a dehydration synthesis reaction between monosaccharides. What does this mean? Water molecules are removed from the bond. 6. For each of the following tests‚ please circle which substance would give a positive result: a. Benedict’s test - glucose tap water oil (lipid)) starch

"clean up" our systems. Excess sugar in the bloodstream can have very serious side effects. The extra sugar impedes blood flow‚ causing wounds to heal more slowly and infections to become more virulent. Just how this excess sugar causes damage remains a topic of debate. One plausible mechanism was suggested in Time by Dr. Michael Brownlee of Albert Einstein College of Medicine in New York City (November 26‚ 1990‚ p. 52-59). Glucose is known to be chemically active and can form a temporary bond

this lab was to observe passive transport of molecules through diffusion and osmosis. We had to keep close observation on two dialysis bags and explain how we measured the change in weight as diffusion and osmosis occurred throughout the experiment. Cells produce an energy called Kinetic Energy. This causes molecules of the cell to move around and bump into each other. Diffusion is one result of this molecular movement. Diffusion is the passive movement of molecules from an area of higher concentration

This paper is my response to the literature by Frances Stokes Berry and William D. Berry titled “Innovation and Diffusion Models in Policy Research” as well as the article by Charles R. Shipan and Craig Volden called “The Mechanisms of Policy Diffusion”. In this essay‚ I maintain that the unified model proposed by Berry and

Simple organic compounds and macromolecules molecules vary in structure and can be distinguished by their functional groups. Molecules of a certain class have similar chemical properties because they have the same functional
