    Introduction The purpose of this experiment was to demonstrate osmosis. Osmosis is the diffusion of water across a selectively permeable membrane (Bell et al 2004). Osmosis is the movement of water molecules from an area of high concentration to an area of low concentration (Brown 1999). Hypertonic is the solution with a higher salt concentration. Hypotonic solution is the solution with the lower salt concentration. My hypothesis is that the potato core will increase in size. When the solution is

    Lab # 2 Diffusion & Osmosis Introduction Kinetic energy‚ a root of energy stored in cells‚ causes molecules to hit into each other and move in new directions. Diffusion is the result of this contact. Diffusion is the random movement of molecules to an area of lower concentration from an area of higher concentration. Osmosis is a type of diffusion. This is the diffusion of water through a selectively permeable membrane from a region of higher water potential to a region of lower water

Furthermore‚ A. franciscana feed on photosynthetic phytoplankton which inhabit areas of light availability but are also more susceptible to predation in highly-lit areas (Biology 108 Lab Manual 2015). Also‚ A. franciscana can withstand a broad range of temperature except extreme values may affect survival (Biology 108 Lab Manual 2015). In this experiment‚ the habitat

    Diffusion and Osmosis lab Results: Figure 1a-rate of weight change in 15 min intervals of each concentration. The first tube showed very little weight change. However all other tubes show a greater change the concentration could be the factor that determines the permeability of the sucrose. The sucrose molecules are too large to pass through. Figure 1b- sucrose concentration determines the weight change. In this case based on our results as concentration increases the percent weight change

    Osmosis and the Egg Lab Report  By: N. Mullins  Date: January 20‚ 2011    Introduction  This lab was designed to explain the different things osmosis does. Osmosis is the  diffusion of water across a semi permeable membrane. Over three days we tested the egg  in three different solutions to observe the changes. On Day 1‚ the main question we  answered was what happened to the egg when it was placed in vinegar? Before doing this  I came to my hypothesis was that the vinegar would eat away at the shell and eventually

    Introduction: The purpose of this lab was to observe passive transport of molecules through diffusion and osmosis. We had to keep close observation on two dialysis bags and explain how we measured the change in weight as diffusion and osmosis occurred throughout the experiment. Cells produce an energy called Kinetic Energy.  This causes molecules of the cell to move around and bump into each other. Diffusion is one result of this molecular movement.  Diffusion is the passive movement of molecules
