Question: investigate the water potential of potato tissue? Introduction All cells require essential materials to ensure their survival. Chemical‚ physical‚ and biological processes are used to move these materials inside of cells. Similar processes move waste materials outside of cells. These processes can be passive‚ occurring as a result of basic physical laws and requiring no outside energy from the cell or they can be active‚ requiring energy expenditure. Since all molecules possess kinetic

Oil is one of the most important resources that empower the economy. It is mainly used for transportation‚ cooking‚ heating‚ and also electricity generation. Without oil‚ transportation‚ manufacturing‚ and production of food may not be possible. Oil came from fossils and dead organisms that submerged to the bottom of the ocean‚ or what we so called Oil Wells. It was collected by oil rigs by digging the bottom surface of the ocean. Deepwater Horizon oil spill is one of the biggest and controversial

nest and the spring that flows all year long ensures that the turtle will not freeze throughout winter. This turtle is located in the temperate deciduous forest biome. This tiny turtle hatches from its egg in late August‚ early September‚ after incubating for forty-two to fifty-six days (Earnst 1994). Shortly after being born‚ together the small turtles burrow into mud or find an abandoned vole or muskrat hole to hibernate in. Around eight years of age these guys finally reach maturity. In the spring

Introduction A bacteriophage is a virus that infects bacteria. A type of bacteriophage is bacteriophage lambda. This specific bacteriophage infects E. Coli. It is composed of protein and double stranded DNA ¡VdsDNA). The DNA of the phage contains around 50‚000 base pairs and codes for 50 proteins. At both ends of the DNA of the phage‚ there are cohesive ends‚ which are composed of 12 nucleotides. Both ends compliment each other‚ which makes the DNA circular once together. This circular DNA

Analysis & Discussion The primary objective of this investigation was to test ultraviolet radiation as an alternative disinfectant for Acanthamoeba in its more resistant cyst form. A previous study had already shown that multipurpose solutions were ineffective compared to hydrogen peroxide based systems at eliminating Acanthamoeba trophozoite contaminations.5 This was a follow-up to that study. Another goal of this study was to test the effectiveness of hydrogen peroxide in eliminating

Next rectal temperature of all horses exposed to strangles should be obtained twice daily‚ and horses developing fever should be then isolated. An isolation period of 4-6 weeks is usually necessary to ensure that the disease is not still incubating before ending the isolation. Disinfection of the stalls‚ water buckets‚ feed troughs‚ and other equipment will help prevent the spread of strangles also. Strangles can produce post exposure immunity after the disease in most horses‚ and protection

3.6.5. Southern hybridization Southern blot hybridization analysis was carried out using standard procedures (Sambrook et al. 2001). Approximately 20 µg of total genomic DNA from transgenic plants and untransformed control plant was digested with EcoRI‚ and then separated by electrophoresis on 0.8% agarose gel. Digestion profile was checked with 1µg DNA‚ with single cutter enzymes EcoRI (10U) in T-DNA region. For southern experiment‚ 20µg DNA was digested overnight. Restricted fragments were separated

Brain Based Learning For many years science and education have concentrated on learning and the mind‚ but today’s neuroscientists and educators are seeing learning from a different scope – the brain. From this viewpoint‚ learning is creating links – by linking the information in which the student has prior knowledge or interest‚ the student is able to expand upon this and learn something else which he can relate it to. For example‚ in a history class when discussing Native Americans‚ a teacher
