    • 7.1: Osmosis and Dialysis Lab Procedure
      This page covers essential concepts in biology and healthcare, including solute concentration, osmosis, and dialysis. It explains solutions and the processes of diffusion and osmosis, emphasizing their impact on cell dynamics. Dialysis is presented as a method for particle separation.
    • 7.2: Osmosis and Dialysis Pre-lab Assignment
      This page explains osmosis and dialysis, highlighting osmosis as the movement of water through a selectively permeable membrane from lower to higher solute concentration, and dialysis as the separation of solutes based on size. It emphasizes the importance of selectively permeable membranes in maintaining cellular homeostasis by regulating nutrient intake and exclusion of harmful substances, thereby facilitating vital biological functions.
    • 7.R: Osmosis and Dialysis (Report)
      This page details experimental findings on osmosis and substance identification. It comprises weight measurements of dialysis bags with different salt solutions to demonstrate osmosis (Part A), tests for chloride, glucose, and starch with observations (Part B), and diffusion observations during dialysis (Part C). The data analysis encourages critical thinking on isotonic, hypertonic, and hypotonic solutions, predicting cellular responses based on osmotic characteristics.
