It has been observed that some persons who suffer renal failure, again suffer renal failure within one year of the first episode. This is due, in part, to damage from the first episode. The performance of a new drug designed to prevent a second episode is to be tested for its effectiveness in preventing a second episode. In order to do this two groups of people suffering a first episode are selected. There are 75 people in the first group...

The patient was under acute renal failure for which the patient underwent renal dialysis to externally filter the blood via osmosis. Dialysis involves the passage of arterial blood through a tube with a semi-permeable outer membrane. This membrane only allows ions/metabolites/electrolytes and water to pass through. Surrounding the tube is another larger tubing containing dialysate (assume pure water). Answer the following questions regarding osmosis and the function that dialysis serves in this case. a.In which direction is the driving force...
