The Aim of this practical was to observe what effect temperature had on the permeability of the cell membrane. Introduction Located within the vacuole of beetroot cells is a red pigment call Betalains. Typically these pigments are contained within the cell vacuole by the tonoplast (vacuole membrane)‚ however When beetroot is heated these red pigments escape the vacuole. This experiment aims to explore the effect of temperature on the permeability of the cell membranes (i.e. Tonoplast)

Janay Wright-Parks Physics-Sports Paper Brad Ingram 29 March 2013 Physics of Gymnastics In the world of sports‚ physic concepts are being applied every day. Most people who play or watch a sport don’t think about the physics behind it all. When I watch a sport like gymnastics‚ I am always amazed at how a person’s body can bend and twist in the way that gymnasts bodies do. It is nothing but physics. Angular momentum is the main physics concept used in gymnastics‚ and this can be seen in events

people fail to realize the importance of physics in athletics. People who are untrained in the scientific field may believe that an athlete’s performance level is solely based on their skill-set‚ such as strength and training. However‚ one’s ability to employ physics concepts is the true determinant for success. This is imperative to dancers; most movement and technique can be improved dramatically by following Newton’s laws accordingly. By utilizing key physics concepts‚ a dancer can improve by locating

The education system I work in follows the curriculum and guidelines set forth by the IB system for the primary‚ middle school and diploma program. I am new to the IB system‚ the curriculum structure and the grading criteria. For the 2013/14 school year I will be working directly with the learning support coordinator as a learning support assistant for two students. My background originally is child and youth work where I have been trained to work with adolescents providing behaviour management‚

Cricket is not a game that most Americans know about‚ however‚ it is a popular sport in Australia and in other British parts of the world. This sport is not unlike any other sport in the area that it involves a great deal of physics. However‚ this paper will focus on the aspect of bowling the ball and the batters reaction to this. When comparing Cricket to other sports that most Americans know‚ the closest match that can be found is baseball. For example‚ a ball is thrown toward someone with

Effect of Temperature on Cricket Respiration Crickets are ectotherms that rely on their environment as a source of heat for their metabolism. Warmer temperatures allow crickets to respire at a greater rate.

Nicole Reardon Biology 1520‚ Section P2 Effects of penicillin and temperature on the growth of Escherichia coli Abstract Bacteria growth is known to be either augmented or impeded by a number of various factors; in this experiment‚ our group tested how E. coli is affected by penicillin as well as how different temperatures can affect bacteria growth. We know that antibiotics are generally specialized against certain types of bacteria—more specifically‚ some are most effective against Gram-negative
