objective of this experiment was to test the effect of a specialized type of diffusion called osmosis‚ “which involves in selective transport of water molecules across a selectively permeable membrane” (Lab Manual 2nd edition). It was hypothesized that osmosis will occur when there is an uneven distribution of solute in a solvent. The more abundant the solute is in solvent‚ the higher the rate of osmosis through the diffusion gradient forming a hypertonic or hypotonic solution. Solvent with equal

Osmosis Experiment Subject: Professor Egg-avier Duration: 3 weeks (Oct 2nd – Oct 16th) Week 1 On October 2nd my group was giving a raw egg (weighing 58.8 grams) and placed it into a clear mason jar with 200mL of vinegar. The ph levels of our vinegar equaled a 2 which tells us that vinegar is a fairly acidic liquid. Once submerged in the vinegar‚ little bubbles began to appear around the egg’s shell. We believed this to be carbon dioxide escaping from the shell. We left our egg to sit in the

How Does Salinity Effect Osmosis in Plant Cells? Introduction Osmosis is a type of diffusion but is the movement of water molecules in and out of the cells from a high concentration to low concentration through a semi permeable membrane. The aim of the experiment is to investigate the effect the salinity of solutions has on the process of osmosis and net weight gain/ loss by potato cells. This would be done by using similar size potato cubes and covering them with different concentrations of saline

Background Information Osmosis is the procedure where water or different types of liquids move through a semipermeable membrane. This type of passage is considered as simple diffusion where no energy is required. This means that the liquid will have

Troy. Good or Bust. Throughout time‚ men have waged war‚ some for power‚ some for glory‚ some for honor and some for love. In ancient Greece‚ the passion of two of history’s most legendary lovers Paris‚ Prince of Troy and Helen‚ Queen of Sparta‚ ignites a war that will devastate a civilization. When Paris steals Helen away from her husband‚ King of Menelaus‚ it is an insult that cannot be suffered. Familial pride dictates that an affront to Menelaus is an affront to his brother.

Not many people can understand the circumstances or the thoughts of the people involved in the “tragedies’ or the “fantasy”. Troy‚ Cory‚ and Rose express the deepest problems or “fences” throughout the most of the scenes. The emotion given off often is heartbreaking as two sons try so desperately to get their father to approve and accept them. In the play it seems Lyons‚ Troy‚ and Cory all have their own types of “fences” isolating themselves away from what they wish to achieve. “Fences” usually involves
