while the other two potatoes remained firm. There was also an awful odor that only came from the potato in the tap water. Conclusion: The hypothesis was correct. The 40% salt solution killed the sailor. This solution was hypertonic which causes osmosis to move the water out of the cell. The sailor then became too dehydrated and died. Salt absorbs water‚ which is why drinking salt water is not good for

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. In other

28 April 2013 Monologue of an Onion Analysis People search forever to find true love‚ but true love will never be found if you can’t find true love within yourself. In the poem “Monologue for an Onion”‚ by Suji Kwock Kim‚ the metaphor isn’t just about the onion it’s also about being loved. Everyone falls in love at least once. And this love feels everlasting and perfect‚ as if it’s never going to end. Then‚ when the moment of heartbreak happens‚ it feels as if the world is crumbling right in

Anjali Patel Riley Egan‚ Nick Morrison 10/2/13 Block 2 LAB REPORT OUTLINE FOR DIFFUSION/OSMOSIS LAB Introduction: Diffusion is the net movement of small or uncharged molecules or substances from areas of higher concentration to areas of lower concentration. There is simple diffusion‚ as explained‚ and facilitated diffusion. Facilitated diffusion‚ on the other hand‚ involves larger or charged molecules or substances that need a protein tunnel through the membrane to help the substance enter and

my aunt’s turn and when we went to eat the mashed potatoes they were super salty. 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

Diffusion‚ Osmosis and Active Transport Substances will move through the membrane by diffusion. This is the random spreading out of particles until they are even. For example‚ when you put your instant coffee in boiling water‚ the coffee particles spread out and fill the entire mug‚ this is diffusion. A second way that substances can move through the cell membrane is by osmosis. This is a special type of diffusion where water moves from a high to a low concentration through a ’partially permeable
