Barrett Bleeden Period 2 Hope for the Future When the curtain falls and Lorraine Hansberry’s play‚ A Raisin in the Sun comes to an end‚ do the Youngers‚ moving into an all white neighborhood‚ have a glimmer of hope in their future? For many years‚ even before the story begins‚ the Youngers seem to know what their future was going to consist of: working for the white man and cleaning their apartment that is constantly encumbered in filth. This drab thought of this family’s existence

Lab One – Diffusion and Osmosis SECTION ONE: Methods Lab 1 – Diffusion and Osmosis can be broken down into four parts (A‚ B‚ C‚ and D). Lab 1A – Diffusion In this exercise‚ we tested diffusion through dialysis tubing. This was done through a demo with the teacher‚ rather than individually in groups. First‚ a piece of 2.5cm dialysis tubing was obtained. Then one end was folded and clipped securely so that a solution poured into the bag would not leak out. Next‚ the other side of the bag was

Diffusion and Osmosis lab Results: Figure 1a-rate of weight change in 15 min intervals of each concentration. The first tube showed very little weight change. However all other tubes show a greater change the concentration could be the factor that determines the permeability of the sucrose. The sucrose molecules are too large to pass through. Figure 1b- sucrose concentration determines the weight change. In this case based on our results as concentration increases the percent weight change

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

Potato Osmosis Introduction: A shipwrecked sailor is stranded on a small desert island with no fresh water to drink. They know they could last without food for up to a month‚ but if they didn’t have water to drink they will be dead within a week. Hoping to postpone the inevitable‚ their thirst drives them to drink the salty seawater. They are dead in two days. Why do you think drinking seawater killed the sailor faster than not drinking any water at all? Today we explore the cause of the sailor’s

2.3. Membranes and modules for forward osmosis: 2.3.1. FO Membranes Generally‚ any dense‚ non-porous‚ selectively permeable material can be used as a membrane for FO. Such membranes have been tested (in flat sheet and capillary configurations) in the past for various applications of FO. In early studies‚ the researchers applied various FO membrane materials‚ including bladders of pigs‚ cattle‚ and fish; collodion (nitrocellulose); rubber; porcelain; and goldbeaters’ skin [36]. By 1960‚ Loeb and

solution‚ the sucrose will over time‚ go through the process of diffusion and be distributed throughout the coffee. Osmosis is movement of H2O molecules passing through a permeable cell membrane to the less concentrated solution‚ eventually to reach an equivalent number of molecules on both sides of the cell membrane. 1.2 The important factors in the process of diffusion and osmosis is H2O being present with soluble molecules that are small enough to be absorbed through the cell membrane to then
