Purpose: To see the effects of tonicity’s on potato cells. Background: Osmosis is the diffusion of water across a differentially permeable membrane due to concentration differences. Tonicity is the concentration of solutes. The potato cell has 3% of dissolved materials. Hypertonic is when the solution has more dissolved materials outside the cell than inside. The cell will lose water this way and shrink. The potatoes in the 5% salt solution will shrink. Hypotonic is when there is less solute dissolved

Diffusion and Osmosis of Solutes and Water Across a Membrane Brittany Bacallao Nova Southeastern University Abstract: This experiment gave a visual understanding of osmosis and diffusion. The first experiment proved that solutes would move down a concentration gradient if permeable to the selective membrane. The second experiment proved different solute concentrations affect the movement of water‚ depending on the solute concentration inside the cell. The purpose of this lab was to look for

SMART Materials A SMART material is a material that is affected by outside influence. Polymorph * Type of thermoplastic (can be reshaped many times). * Normally supplied in form of granules or small plastic beads. * Low fusing temperature of around 60°C. This means it can be reduced to a mouldable condition by immersion in hot water. * Once fused turns from opaque to clear. * Heating above 65°C is dangerous as it will become a sticky-adherent mass‚ similar to hot-melt glue

There are several reasons as to why I believe Capital Punishment should be legalized in Britain once more and I will explain why in due course. Firstly‚ I would like to mention the different variations of a life sentence in prison because there is not one set length of time a criminal can spend locked up for the same class of crime. A life sentence is given to those whose offense is particularly grave; for example by law it is mandatory for a Judge to give a life sentence to all criminals who are

Final Piece Assessment- Development The Circus The object of the first task set was to create a performance in response to the stimulus given. The stimulus we received was a short passage from a story describing a circus‚ the description allowed us to freely explore our different interpretations because it was a broad and different approach to the typically happy and childlike setting of a circus. As a whole the class responded with quite abstract and solemn pieces‚ I feel the physical theatre
