PHYSIO EX 1 Simulating Dialysis (Simple Diffusion) 1. Describe two variables that affect the rate of diffusion. The temperature of the solutions and the difference in concentration of the ion or molecule between the sides of the membrane 2. Why do you think the urea was not able to diffuse through the 20 MWCO membrane? How well did the results compare with your prediction? Since the chemical formula for urea is (NH2)2CO and its molecular weight is about 60. It will not diffuse through the

Q1: Describe the basic assumptions of Economics. Ans- The basic problem of economics can be summarized in one sentence: How to best satisfy unlimited wants with unlimited resources. We can break this problem into two parts: Preferences - What do we like‚ what do we dislike. Resources - We all have limited resources. Even Warren Buffett and Bill Gates have limited resources. They have the same 24 hours in a day that we do and neither is going to live forever. All of economics‚ both microeconomics and
