Review Sheet 1 Results 1. Describe two variables that affect the rate of diffusion. Your answer: Two variables that affect the rate of diffusion are the MWCO membrane and the solute concentration. Increasing the membrane size and solute concentration will also increase the average diffusion rate. Decreasing the membrane size and solute concentration will reduce diffusion rates and can even prevent all diffusion. 2. Why do you think the urea was not able to diffuse through the 20 MWCO membrane

1) The article “The Sports Business as a Labor Market Laboratory‚” by Lawrence M. Kahn focuses on data on the rise and fall of rival sports leagues and the granting of free agency rights in professional sports and other things. I read pages seventy-five to eighty-three of the article. Overall‚ sports owners are a small and interconnected group. This suggests that they have the ability to band together and act as monopsonists in paying their players. A monopsony is a market condition that exists

Safety in a microbiology laboratory is important in the prevention of infection that might be caused by the microorganisms being studied. This laboratory does not require the use of virulent human pathogens. However‚ many types of microorganisms are potentially pathogenic. This means that‚ although they would not cause disease in a normal healthy host‚ they might possibly do so if a large enough quantity of the microbes came into contact with a compromised host‚ such as by wounds and cuts.

The Smurfette Principle The Smurfette principle is a controversy on how TV shows and movies have all men/boys as characters with zero to one girl. A writer by the name Katha Pollitt writes an article in the New York Times talking about this principle. She defines her principle as‚ “…a group of male buddies will be accented by a lone female‚ stereotypically defined” (Pollitt). She uses her daughter to explain to us that there is just not enough shows for little girls to watch. She mentions how

DeVito (2012) claims that the Principles of Communication have numerous practical implications for our communication effectiveness. Studies suggest we are estimated to communicate and interact for up to 75% of everyday. However‚ all this time communicating doesn’t necessarily mean we are always communicating effectively‚ seen through events such as divorce‚ broken family relationships and friendships and dissatisfied employees and employers (Tubbs‚ S.‚ 2010). Tubbs (2010‚ pg. 25) states “most generally

Laboratory #1 Introduction to Laboratory Techniques Sean Pence Jackie Butler September 6‚ 2012 September 13‚ 2012 Abstract: This lab contains four different experiments. All four experiments focus on proper laboratory techniques. The reasoning behind this lab was to become familiar with lab equipment‚ the proper usage of lab equipment‚ and how to correctly take data and notes. The first experiment of this lab was to determine the volume of water in various types of equipment. The second experiment
