amount of sucrose concentrations. The higher molarity concentrations increased the movement of water to balance out the inside of the tube and the beaker. The greater amount of concentration gradient‚ in each tube‚ increased the rate of osmosis. This rate of osmosis is due to the net movement of water from an area of low concentration to an area of high concentration. Because the tubes had different concentrations‚ certain tubes gained more mass than others. Solution A had 0.6 molarity which increased

According to Nicole King‚ "Race is a word and a category that can simultaneously denote a person’s color‚ caste‚ culture‚ and capacities‚ oftentimes depending on what historical‚ political‚ or social forces are at work". A Raisin in the Sun by Lorraine Hansberry is an attempt to examine the impact of racial discrimination on the life of an ordinary black family. It is also a testament of this family struggling to manage with racism and poverty in the Washington Park Subdivision of Chicago’s Woodlawn

Thus‚ he makes fun of her unnatural assimilationist hair and Beneatha is upset because she wants to blend into society‚ instead of sticking out. The second piece of evidence to support that that the word “ hair” was the most important word in A Raisin in the Sun can be seen through hair’s symbolism in the text as a powerful statement from Beneatha that symbolically declares through her opinion that natural is beautiful. Thus‚ she tries to make a powerful statement towards George. He isn’t too happy

He uses five similes in Harlem: “like a raisin in the sun‚ like as sore‚ does it stink like rotten meat‚ like a syrupy sweet‚ like a heavy load”. Then he uses a metaphor: “or does it explode”. All of these comparisons make me image the things he is comparing. You can visualize‚ smell‚ taste‚ and feel these things. The point of this poem is what happens to a dream deferred. Lorraine Hansberry used this one line taken from the poem “Harlem” to compare the raisin to life. There was a lot of things

Introduction: The purpose of experiment 1 was to demonstrate the principle of simple diffusion and understand how to make % solutions. Exercise 2 demonstrated the principle of osmosis: observing the movement of water by osmosis from an area of lower concentration of a solute to an area of higher concentration of a solute. Materials and Method: Refer to pages 47-51 of Bio 203L Lab Manual. Results/ Discussion: The effect of the chloride ion on its rate of diffusion in agar means it will diffuse

Essay Test 1.) At the beginning of the play Walter Lee has breakfast with his son‚ and wife. As the meal continues you witness the deterioration of Walter and Ruth’s relationship. Walter expresses his dreams about owning a business which is an everyday thing for Ruth. She has grown tired of hearing. The disappointments of the ghetto‚ living with four other people‚ and being pregnant with a second child has gotten to Ruth‚ her hopes and dreams are crushed. Sadly‚ Ruth has succumb to reality and can

Title: Potato Osmosis Abstract: In this experiment was designed to study the effect of a concentrated solution applied to white and sweet potatoes. The solution’s impact among the potatoes were to be either hypertonic‚ hypotonic‚ or isotonic. The potatoes were first cut into fries with a fry cutter‚ and then weighed after being cut. The white and sweet potatoes’ weights ranged from .005-.015 grams. A total of 18 sugar solutions are to be made over the course of 3 trials. In each trial‚ 6 different

Potato Osmosis and Diffusion Lab Report Emily Cocq Research Question: Will there be a difference in the experimented potato cores after being subjected to high concentrations of sugar? Introduction: Water can move through protein channels in cell membrane/cell walls. The water will move due to the water potential of the cells. If there is a greater concentration of solutes (chemicals) inside the cell than outside the cell and the chemicals can not move‚ then water will respond by moving

Hands On Approach to Diffusion and Osmosis Abstract A. Plant and Animal Cell Diffusion and Osmosis In this experiment we observed carmine powder to better understand the concept of Brownian motion and the role of molecular movement in diffusion. The particles continuously moved in a completely random fashion‚ and the smaller particles moved with more speed than the larger particles. B. Potato Core Experiment In this experiment we estimated the osmolarity of potato tuber tissue
