Joscely Garris Professor Vinh Hoang CHEM 1151L – 254 25 October 2013 Preparation of Viscous Solution This report discusses an experiment to study the relationship of solute/solvent and the calculations involved to measure the concentration of the solution. The first experiment to take place is the preparation of a salad dressing using xanthan gum solution‚ water and oil. Commonly used as a food thickening agent‚ Xanthan gum is a large molecule composed of several saccharides linked together

There are four biological marcomolecules essential to the function of a cell: lipids‚ proteins‚ carbohydrates and nucleic acids. Proteins are made up of amino acids that have a carbon in the center of the structure with four chemical groups attached to the sides. Traditionally protein is understood to assist in the development of muscle in athletic people‚ but it actually functions as structural support‚ cell adhesion‚ transport for molecules‚ and cellular communication. Through dehydration synthesis

There are of course many potential threats to biological diversity in Canada. Changes to the landscape (generally done by humans)‚ can have a devastating affect on biological diversity‚ due to the destruction of the previous landscape (whether lakes‚ rivers‚ forests‚ or whatever) for human use. Another is pollution‚ there are of course many different forms of pollution‚ so to be more specific‚ air pollution can have a devastating affect on biological diversity in Canada. Not only can some emissions

being cognitive and biological. The cognitive perspective suggests that emotion is based more on the factors of the mental processes. The biological perspective suggests that emotion is influenced by biological systems and performances and is based on physiological responses. It has been suggested that there is a possible interaction between cognitive and biological processes that influence emotions. Le Doux’s theory of the biological pathways focuses solely on the biological explanation of emotion

Solutions Solutions are a combination of solvents and solutes. When a solute dissolves into a solvent‚ the combined product of the two reactants is called a solution. The definition of a solute is the reactant that’s being dissolved. The only difference from a solute and a solvent is that the solvent is the one that’s doing the dissolving. Molecules randomly flow in all directions until there is an equal concentration throughout the solution. The dissolving process can vary depending

The primary objective of this experiment is to determine the stress that various alcohols have on biological membranes. Membranes within cells are composed mainly of lipids and proteins and often serve to help maintain order within a cell by containing cellular materials. Different membranes have a variety of specific functions. One type of membrane-bound vacuole found in plant cells‚ the tonoplast‚ is quite large and usually contains water. In beet plants‚ this membrane-bound vacuole also contains
