    Permeability of soil

    Permeability is measured in term of water flow through the soil in a given time. The soil permeability is a very important factor to study the behavior of soil in its natural condition with respect to water flow. The size of pore space and interconnectivity of the spaces help determine permeability, so shape and arrangement […] More

    Effect of lipid solubility on permeability of plasma membrane

    : To study the effect of lipid solubility of molecules on permeability of plasma membrane of animal cell. Introduction : Diffusion: In general, diffusion process occur when there is a concentration gradient between two region .Molecules (other than water) will move by diffusion as long as there is a concentration gradient. A concentration gradient exists when […] More

    Cell Transport Mechanisms and Permeability

    Cell Transport Mechanisms and Permeability Purpose The purpose of this lab is to teach me simulating dialysis, simulating facilitated diffusion, simulating osmotic pressure, simulating filtration, and simulating active transport. Hypothesis If I increase the concentration of sodium chloride from 9mM to 18mM in the left beaker, then the rate of diffusion will increase, because concentration […] More

    Physio Ex 9.0 Activity 1 Cell Transport Mechanisms and Permeability

    ACTIVITY ONE- Cell Transport Mechanisms and Permeability: Simulating Dialysis (Simple Diffusion) 1. Describe two variables that affect the rate of diffusion. Molecular weight affects the rate of diffusion because the bigger the size of the molecule the longer it will take to diffuse. Membrane size is another variable that affects the rate of diffusion because […] More
