- • Estimation of the Water Potential (Ψw) of Storage Tissue by Volume Change Method Observe these experiments in these links: https://www.youtube.com/watch?v=jTDATlaBV-o https://www.youtube.com/watch?v=k1O9jBHgsxs Estimates of water potential of various tissues have been obtained after equilibrating the tissues in solutions of different osmotic potentials. The principle depends upon finding the concentration of sucrose that would cause no change in weight of the tissue before and after an incubation period in the solution. This concentration may be assumed to have a water potential equal to that of the tissue.Consider the following release data for a drug in water Q (Cumulative amount released in mg/cm?)

- Question: Calculate the Rate Ratio of Giardia among hikers that filter water compare to hikers that don't filter water. 1.00 0.23 0.33 0.11 E+ = filter E-= no filter D+ = Giardia D-= no Giardia Patient Number E+1 E+ 2 E+ 3 E+4 E-5 E-6 E-7 E-8 1 X 2 3 Day X 4 X X 5The effect of pressure on flow rate Set-up: For investigating the effect of pressure (height of a column of liquid), a 50-mL burette was used with a small length of rubber tubing fixed to the bottom on which a clamp could be fitted to start/stop the flow of water (Figure 1). Effluent was collected in a beaker and mean flow rate was calculated (mL/s), and a stopwatch was used to measure how long it took for 5 mL of liquid to flow out. For the subsequent sections of the practical, a 25-mL burette was used, and the top was connected via rubber tubing to a 5-liter reservoir placed on the shelving above the bench. The tubing at the base was connected to the different flow modules that comprised the different configurations of tubes to be tested. Interpret the graph. What does this relate to in the cardiovascular system, and is it something that can change? How? What would be the implications for our ability to control blood flow to different tissues, if this were the only control mechanism…During transfer of liquids using a micropipette: What would it mean if the mean is very close to the expected value but your standard deviation is high ?
