salt (Na)‚ 0.897% Na‚ 5.0% Na‚ and distilled water with a 0.0% Na solute concentration. My hypothesis is that cellular form and contents will either change or maintain form and consistency when introduced to these various different environments as osmosis occurs until a dynamic equilibrium has been reached between the membrane and its environment. It was found that when RBC’s are introduced to various solute concentrates their form and consistency did changed with highest amount of hemolysis evident

specific shade of light‚ we can adjust it to however bright or dim we want it to be to help in different situations. Problem What materials can be used to make a dimmer switch? Hypotheses If we replace the pencil lead with a piece of rubber tubing or an insulated copper wire‚ the brightness of the light bulb will decrease. Research Dimmers were first introduced by Granville Woods in 1892 for theater use. The early dimmers were made for commercial purposes like theaters and halls

more permeable to water. When ADH is increased in the blood flow‚ more water-permeable channels are inserted‚ allowing more water to be reabsorbed by osmosis into the blood stream. When this happens‚ less urine‚ of a much lowered water potential‚ passes out of the body. This suggests that due to the cell walls being more permeable to water and also osmosis reabsorbing the water‚ this in turn lead to Leah’s water intoxication‚ as it was stored in the body opposed to leaving it correctly.

Research question; This investigation will determine how different concentrated sugar water will affect to the mass change of the potato cells using the concept of osmosis. Hypothesis; I predict that the potato slice in beaker C will gain the most increased mass than beaker B and C. The reason is that since beaker C has a highest

selectively permeable membrane is a special case of diffusion known as osmosis. Osmosis results in the movement of water from an area of lower concentration of dissolved material to an area of higher concentration of dissolved material. For a demonstration of this principle‚ a purple onion cell is going to be bathed in different concentrations of salt (NaCl) water. Problem: How do solutions of various salt concentrations influence osmosis in relation to an onion cell?

Adjust the set-point value of the temperature controller to approximately 5 degree below the room temperature. Allow the water to cool down until it is safe to touch. Open the drain valve and empty the water tank. Detach the flexible tubing and clean the capillary tube for next use. (Refer to priming procedure) Switch off the main power. Unplug the main cable if the equipment will not be used for a long period. EXPERIMENT
