It is expected that if the concentration of sucrose increases from 0.0 M, 0.2 M, 0.4 M, 0.6 M and 0.8 M (±0.01 g) in a 40 (±0.5) mL sucrose solution, then the average percent change in mass in Solanum tuberosum core will decrease. This is because if the Solanum tuberosum cores are placed in a hypotonic sucrose solution, which is described as having lower osmolarity, than the percent change in mass of the Solanum tuberosum core will increase due to the fact that water molecules will be moving…

The genetic combinations; two normal genes, one normal and one cystic fibrosis, and two cystic fibrosis, each affect the membrane proteins involved in transporting chloride ions through the cell membrane. Two normal genes would not alter whether or not the membrane proteins would correctly shield the chloride ions so that the ions could pass through the cell membrane. With this ability of the chloride ions successfully transporting across the cell membrane the body would not generate a…

“A physical manifestation of the struggle between Soviet Communism and American capitalism that stood for nearly thirty years, the Berlin Wall was the high-risk fault line between East and West on which rested the fate of all humanity.” (Taylor, vii) “I hope that those who live in more fortunate communities elsewhere in the world will summon up the imagination to conceive what it might have been like for Berliners to have such a barbarous fracture inflicted on their cities, their neighborhoods,…

The Berlin Wall The Berlin Wall Imagine being a teenage girl separated by a wall, without your family, friends, and sometimes food. How would you feel? Many people were greatly affected by The Berlin Wall. Waking up being separated by a wall was many people's everyday life. Once the wall was built, people could not leave the side they were on. Germans could not visit friends or family on the other side of the wall. The Berlin Wall has and always will be the greatest…

freedom, to travel across Europe without being in fear. There freedom should not be held back by this wall. They cannot live in fear the rest of their lives. The United States is all about freedom, furthermore that is why many presidents in the past have traveled to Berlin, to help get their freedom back. Living in fear means losing good opportunities. General Secretary Gorbachev fears that if the wall is torn down the Soviets will come in and try to take over Germany. President Reagan…

Amoxicillin is an beta lactam aminopenicillin that inhibits bacterial cell wall synthesis by binding to penicillin binding protein and blocking transpeptidation. It has low protein binding and is eliminated renally and mostly unchanged. It has a beta lactam ring, an absolute configuration of 2S, 5R, 6R, a carboxylic acid group at C2 position and an amide bond at the C6 position. It has broad spectrum activity and can be used against gram negative bacterial infections. Erythromycin is a…

Concentration Gradient effects the rate of Osmosis in Artificial Cells. During our biology lab we learned all about cells, and to further our understanding we even conducted an experiment with an artificial cell. To start the lesson, we learned the difference between diffusion and osmosis, how concentration gradients affect both. Also how the cell membrane works, how tonicity affects plant and animal cells differently, how dialysis tubing works, and how it acts like a living cell. By the end of…

Each lectin molecule usually comprises of two or more carbohydrate-combining sites, i.e., they are di- or polyvalent. Concanavalin A (a tetramer protein originally extracted from the jack-bean, Canavalia ensiformis) is a member of the legume lectin family and is a particular lectin that has been observed to be able to agglutinate a multitude of cell types, including myocytes, B-lymphocytes and fibroblasts, but for it to perform this action, it needs the presences of sugars which include mannose…

supporters of the wall said that the wall helped prevent German neo-Nazis from move onto the East. Also, the supporters saw the wall as a sign of the division of Germany and hoped for peaceful negotiations to occur. Those who opposed the wall said that it was a sign that East Germany was going bankrupt. Those who opposed the wall also saw the wall as a violation of the Four-Power status by the Soviet Union. There were tensions between the two sides of Germany and their views on the Berlin Wall…

The Berlin Wall was a barrier that separated the west side of Berlin from the east side of Berlin. The wall was built in 1961, and torn down in 1989 (History.com Staff, 2016). The Berlin Wall was built to keep the fascists of West Berlin out of East Berlin, and to make sure that the fascists had no influence on the socialist state of East Berlin (History.com Staff, 2016). Berlin was in the heart of the portion of Germany controlled by the Soviets, or as Soviet leader Nikita Khrushchev put it,…
