Aim To investigate the effects of increasing salinity on potato cell mass. Background Information This experiment is based upon osmosis. Osmosis can be defined as the net movement of water molecules from a region with high concentration to a region with low concentration. This movement must take place across a partially permeable membrane such as a cell wall‚ which lets smaller molecules such as water through but does not allow bigger molecules to pass through. This process will take place until

Children‚ Cell Phones‚ and Possible Side Effects There are possible health risks that go along with allowing a child to use a cell phone. This subject has been debated for years. Many researchers and health care professionals have done studies and given their opinions about it. Although cell phone companies do not opening warn you when you purchase a cell phone‚ I take the advice of risk very seriously. Being a mom‚ I found the following information very helpful when deciding that a cell phone

Dark Tech: The Effect of the Cell Phone on Health Today’s technologies are advancing at such an astonishing rate. This can make it difficult for even the most avid “techie” to keep pace. Technology is that wonderful thing that brings comfort and convenience to our lives. But‚ with that comfort and convenience‚ there often comes a price; and the technology of the cell phone proves no exception. Arguably‚ as a communication tool‚ the cell phone has no equal in how it has changed and affected

Effects of Sucrose Concentration On Cell Respiration In Yeast Abstract This lab investigates the effects of Sucrose concentration on cell respiration in yeast. Yeast produces ethyl alcohol and CO2 as a byproduct of anaerobic cellular respiration‚ so we measured the rate of cellular respiration by the amount of CO2 produced per minute. The results show a trend wherein increased concentrations of sucrose increase the rate of cellular respiration. Introduction All living cells require energy

Root Surface Caries Caries can affect any surface of the teeth. The most commonly seen caries are found on the crown of a tooth‚ above the cemento-enamel junction‚ it is also possible for caries to form on the root surface‚ below the cemento-enamel junction. Dental root caries has received a great deal of attention in the past few decades. A variety of different patients are at risk for root surface caries. Dentists use several methods of treatment. Root surface caries are also called cemental
