Osmosis Lab Conclusion The purpose of this lab is to determine whether salt affects the movement of water in the cell. Independent variable is the factor that affects the value of variables dependent to it. In osmosis lab‚ the independent variables are the potato and onions. The dependent variable is the variable whose value is measured to determine the extent of the effect of another variable to it‚ as in an experiment. In osmosis lab‚ the dependent variable is the length of the potato. The controlled

Introduction The purpose of this experiment was to demonstrate osmosis. Osmosis is the diffusion of water across a selectively permeable membrane (Bell et al 2004). Osmosis is the movement of water molecules from an area of high concentration to an area of low concentration (Brown 1999). Hypertonic is the solution with a higher salt concentration. Hypotonic solution is the solution with the lower salt concentration. My hypothesis is that the potato core will increase in size. When the solution is

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 be kept in mind that sucrose is not permeable

and prospect to determine their fates. This theme relates to the three generations of women mentioned in Lorraine Hansberry’s A Raisin in the Sun because the daily dilemmas and altercations in the Younger family may cause Beneatha‚ Ruth‚ and Mama to convoy the same fate though they have diverse expectations for the future. The role of the younger aged woman in the raisin in the sun addressed as Beneatha Younger is the first stage of development of feminism. Her character would be described as hard

authors use to convey complex deeper meanings. Symbolism is the act of representing ideas using symbols‚ like the Mockingjay in the “The Hunger Games” or the scar in Harry Potter. One such book that loves to use symbolism is the drama based play the “Raisin in The Sun” Written by Lorraine Hansberry. The story is about a poor black family struggling in South Chicago during the Great Depression. The Younger Family gets a $10‚000 dollar insurance settlement which they hope will greatly improve their lives

Lab report OSMOSIS TROUGH A SELECTIVELY PERMEABLE MEMBRANE Introduction: Molecules have kinetic energy. This causes the molecules of the cell to move around and bump into each other. Osmosis is a special kind of diffusion where water moves through a selectively permeable membrane (a membrane that only allows certain molecules to diffuse though). Diffusion or osmosis occurs until dynamic equilibrium has been reached. This is the point where the concentrations in both areas are equal and no

This poem shows the real meaning of the play because it showed the internal and external struggles each one of the characters had.
