because dreams are the key to setting your goals so you can achieve further in the future. In Lorraine Hansberry’s play A Raisin in the Sun‚ this quote is true because of Walter’s dream to be the man of the house‚ Benethea’s dream to live past society’s expectations of an African American woman and become a doctor‚ and Mama’s dream is to have her family united as one. In A Raisin in the Sun‚ one character who has a dream is Walter. Walter’s

Introduction: The purpose of this lab was to observe passive transport of molecules through diffusion and osmosis. We had to keep close observation on two dialysis bags and explain how we measured the change in weight as diffusion and osmosis occurred throughout the experiment. Cells produce an energy called Kinetic Energy. This causes molecules of the cell to move around and bump into each other. Diffusion is one result of this molecular movement. Diffusion is the passive movement of molecules

Osmosis and diffusion are sometimes mixed up without much thought‚ but they are very different in many ways. Osmosis is a defined as the movement of water through a semipermeable membrane (). The membrane is fully permeable for the small water molecules‚ but is selectively permeable to any substance that is lager that a normal water molecule. One example might be a glucose and water mixture‚ when the solute is put into one side of a U-shaped tube that has a semipermeable membrane between the solvent

Dreams‚ hopes‚ plans‚ race‚ and pride these are just many of the themes in the play A Raisin in the Sun. The play is about the Youngers an African American family who live in the South Side of Chicago. The Youngers were a big family there was Ruth Younger‚ Travis Younger‚ Walter Lee Younger‚ Beneatha Younger‚ and Mama Younger. All of them lived in a small crammed apartment that was in a poor neighborhood. The Youngers got a check in the mail for $10‚000 and that was their chance to move into a bigger

Lab Topic: Movement of Materials Across the Cell Membrane—Potato Tuber Cells Introduction: Osmosis is a form of diffusion in which water diffuses through a selectively permeable membrane from a region of high concentration to a region of lower concentration. This form of diffusion takes place when the molecules in high concentration are too large to move through the membrane. Three factors that determine cell membrane permeability are shape‚ size‚ and polarity. For this experiment‚ it must

Egg Osmosis Lab The purpose of this lab was to demonstrate an example of a spontaneous reaction and its connection to metabolism; in this case it was osmosis. The procedures that we used to complete the experiment were taking five eggs that had been soaked in a sucrose solution and then placing each one in containers of sucrose that each had different levels of concentration. The mass of each egg was measured before being placed into the solutions and then every 10 minutes after until they had soaked

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

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
