Diffusion and Osmosis Introduction Tonicity refers to the concentration of solutes in a solution (Lab 6-7). There are three stages of tonicity: Isotonic‚ hypertonic and hypotonic. Four unknown solutions were given and labeled as followed: Solution A‚ Solution B‚ Solution C‚ and Solution D. Since potato cells were used for this type of experiment‚ in an Isotonic solution the solute and water concentration are the same as inside the cell in which the isotonic solution contains 0.9% NaCl.

poem‚ “Fences‚” Troy is someone who doesn’t care what anyone says about him. He’s his own person and he likes to be open about his problems. I think that Troy is someone who is polite‚ nice‚ and somewhat thinks he knows it all. Troy doesn’t care if his wife‚ Rose‚ doesn’t want to hear about death.

play has had many positive responses to blacks and whites in this society. It is about protagonist Troy Maxson as well as his african american family that is filled with drama and excitement. In Wilson’s Fences by Joseph Wessling he expresses‚ “Fences is about the always imperfect quest for true manhood. Troy’s father was less of a “true” man than Troy‚ but he was a hard worker and a provider. Troy‚ even as a runaway‚ carried with him his father’s virtues along with a considerable lessening of the

After thanksgiving dinner that year I became interested in figuring out how the using the same recipes the outcome could be so different. Background Information: Osmosis is the of a solvent across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration. The water being the solvent can move across the membrane but the salt

For this assignment‚ you will first need to read the Iliad closely‚ enough that you will become familiar with all the characters (ones who appear over several lines of text‚ and have “speaking parts”). Having acquired this familiarity‚ you will then watch the film Troy‚ paying

concentration than itself‚ the potato chips lost weight. As there was a higher concentration of water molecules inside the potato chip compared to the concentration of water molecules outside the potato chip. It was stated in my prediction that osmosis is the diffusion of water molecules from a high to a low concentration‚ therefore water molecules from inside the potato chip moved out into the solution. Leading to the cytoplasm inside the cells to shrink and become flaccid. As the cells of the

or volume of the plant cells does not change‚ means there is no net loss or gain of water. Introduction This study shares the results of an effort to understand diffusion and osmosis in general. It focused more into osmosis in plants cell‚ and how to indirectly measure osmolarity in potato tuber tissue. Osmosis is the diffusion specifically of water across a membrane. Diffusion occurs when certain substance‚ such as an ion‚ is more concentrated on one side of membrane. If the membrane allows
