A Raisin in the Sun: Dependency “Weariness has‚ in fact‚ won in this room. Everything has been polished‚ washed‚ sat on‚ used‚ scrubbed too often. All pretenses but living itself have long since vanished from the very atmosphere of this room.”(23-24) A Raisin in the Sun is a play of dependency‚ where events are dependent on one other events. Monetarily‚ the Youngers depend on the insurance check to rescue them from the weariness and familiarity of their one room apartment. Between all the talk

Osmosis in Red Onion Cells By: Youssef Gharib Brief Description of Osmosis in Red Onion cells: Osmosis is the diffusion of water from an area of low concentration to an area of high concentration across a semi-permeable membrane. The purpose of this lab is to compare the three different types of solutions affect on the relative size of the vacuole to the cell‚ the outer membrane of onion red cells (tunics) are used to figure out the different types. In the red onion you can see effects promptly

Introduction This experiment was osmosis and diffusion. In this experiment I began by calculating the volume of a fresh chicken egg. Then to determine the effect of osmotic pressure change on a cell I soaked the raw chicken egg in vinegar for 24 hrs‚ and measured the volume of the egg after the shell had been dissolved by the vinegar. The egg was then submerged in corn syrup for 1-24 hrs‚ then measured and recorded the new egg volume. Finally the egg was submerged in water for 1-24hrs‚ again the

partially supported because glucose left the bag and is proven by the positive test on the surrounding water. Also the beaker turned orange because of osmosis which attests to glucose leaving the bag. Iodine Potassium Iodine and water entered the bag. This was proven by the color change in the starch test as the bag turned black also because of osmosis. The only thing that the hypothesis lacked was that starch did not move at all. The beaker stayed yellow before and after because the bag is not permeable

Introduction: The objective of this experiment is to demonstrate osmosis by using an egg as a model. In order for this to happen the vinegar will make the eggs shell disappears. The reason for this is because vinegar has acetic acid and the shell has calcium carbonate‚ when these come into contact it produces carbon dioxide. This is the reasoning for the little bubbles when the egg is first put into the vinegar. After the shell discinigrates it will become rubbery from the acetic acid‚ at this
