Diffusion & Osmosis: Introduction: This experiment was performed to demonstrate the process of osmosis and to show visible as well as quantitative evidence proving that osmosis occurred. Through the tasks of determining the percent concentrations in two different solutions‚ we were studying the process of osmosis. Osmosis is the best way to perform this experiment because as we went through the experiment‚ the weight of the beaker/dialysis tubing changed and the only logical explanation was

The thyroid gland is an important organ of the endocrine system and located in front of the neck below the larynx consisting of two lobes on each side of the windpipe. It regulates the physical and chemical processes that occur at the cellular level. It regulates the manner and rate at which the tissues utilize food and natural chemicals for the production of energy and to expend that energy into body heat and muscular energy. The thyroid gland produces hormones from the thyroid tissue cells called

Abstact 1) Introduction An adulterant is a chemical substance which should not be contained within other substances‚ such as food‚ beverages‚ fuels‚ for legal or other reasons. The addition of adulterants is called adulteration. The word is appropriate only when the additions are unwanted by the recipient. Otherwise the expression would be food additive. Adulterants when used in illicit drugs are called cutting agents‚ while deliberate addition of toxic adulterants to food or other products

The process of osmosis and its importance to living organisms Osmosis is the process by which there is a net movement of water through a semi permeable membrane from an area of high water potential to an area of low water potential. Within a cell‚ osmosis has the following effect. If the water potential of the cell is lower than that around the cell water will move across a concentration gradient into the cell. If this is the case‚ the increase in water in the cell‚ may cause the cell to swell

The results showed that the sucrose solution of 0.0M in the solution lacking AgNO3‚ showed the cells expanded‚ to the point of explosion from a hypotonic solution( Figure 1). Incipient plasmolysis occurred in the solution that contained AgNO3 in the sucrose concentration of 0.4M (Figure 2). In addition‚ the Elodea cells seemed to shrink as the sucrose concentrations’ increased without AgNO3. Therefore the results were that with the addition
