Cell Transport Mechanisms and Permeability 1 EXERCISE 1 OBJECTIVES 1. To define the following terms: differential permeability‚ passive and active processes of transport‚ diffusion (simple diffusion‚ facilitated dif- fusion‚ and osmosis)‚ solute pump‚ pinocytosis‚ and phagocytosis. 2. To describe the processes that account for the movement of sub- stances across the plasma membrane‚ and to indicate the driving force for each. 3. To determine which way substances will move passively

PHY 114: General Physics Laboratory Lab 1: Absorption of Nuclear Radiation 09/04/13 Abstract Nuclear physics was practiced to find the value of tau. After 8 trials of using a G-M counter and 8 different mass thicknesses of polyethylene‚ a graph was formed and tau was calculated to be 0.1931 cm^2/g‚ an error of 3.57% from the accepted value of 0.2 cm^2/g. Experiment was also used as an intro to using basic lab equipment‚ computer programs and calculating errors. With many different

Natalia Wierzchon A.P. Biology Lab: 1. Osmosis 09/10/2010 I. Introduction a. Purpose: The purpose of this lab was to observe the diffusion process of water‚ osmosis‚ as well as create an understanding of water potential‚ the basis of osmosis. The experiment proved how water molecules in a solution are able to move from an area of low solute concentration‚ high water concentration‚ to an area of high solute concentration‚ low water concentration‚ diffusing “down” the water gradient.

Chapter 1 exercises Exercise 1 A. Our experiments suggest that there are dangerous levels of chemical X in the Ohio groundwater. However‚ others argue that the Ohio groundwater has been used for drinking and no complaints were found. B. While they rarely admit it as much‚ historians often take for granted that material forces drive history. C. They say proponents of Freudian psychology question standard notions of “rationality”; I say that in fact many mathematicians use rationality to
