Diffusion and Osmosis NGSSS: SC.912.L.14.2 Relate structure to function for the components of plant and animal cells. Explain the role of cell membranes as a highly selective barrier (passive and active transport). SC.912.L.14.3 Compare and contrast the general structures of plant and animal cells. Compare and contrast the general structures of prokaryotic and eukaryotic cells. AA Background: (Source: www.explorelearning.com) Diffusion is the process in which there is a net movement of

Introduction: Diffusion and osmosis are passive processes of transport. Passive transport involves no disbursement of energy by the cell. Diffusion movement is from high concentration to low concentration‚ which the driving force for this type of movement is kinetic energy particles themselves. Which crystal (Methylene blue‚ solid or Potassium Permanganate KMnO4-purple) will move further than the other due to the driving force (kinetic energy)? My prediction is that Potassium Permanganate KMnO4-

Diffusion is the molecular net movement from a higher concentration to a lower concentration. For instance‚ when a person is smoking‚ the smoke diffuses into the air. The molecules in the smoke‚ released from the cigarette‚ travel through the air. Here is how it occurs. When molecules are close enough‚ they collide with each other‚ their kinetic energy changes. Due to the direct relationship between diffusion and molecular kinetic energy‚ the molecules move away from the point of the collision as

AP Biology Osmosis and Diffusion Lab I. Introduction: Diffusion is vital to many life functions of a cell‚ it allow the transportation of vitally important nutrients and compounds without the expenditure of excess metabolic energy. To explain diffusion‚ it is as if a bottle of perfume is opened at one end of the room‚ then in a short amount of time a person at the other end of the room can detect the scent of the perfume; this is the process of diffusion. Diffusion is a movement from a higher

SIMPLE DISTILLATION OF VODKA (ANTONOV) Kristel Joy M. Tan‚ Joshua Michael L. Torres‚ Pauleen Anne S. Vanadero‚ Paulene Arielle P. Ynzon and Rachel Pauline E. Zaballero Group 10‚ 2D Medical Technology‚ Faculty of Pharmacy‚ University of Santo Tomas ABSTRACT Distillation is the most common technique‚ it is a process wherein the liquid is separated from the solution by boiling the liquid solution and condensing the vapor in order to get the distillate. There are four kind of distillation: simple distillation

Diffusion Through Membranes IB Biology 11 Diffusion Through Membranes OBJECTIVES In this experiment‚ you will Use a Conductivity Probe to measure the ionic concentration of various solutions. Study the effect of concentration gradients on the rate of diffusion. Determine if the diffusion rate for a molecule is affected by the presence of a second molecule. BACKGROUND Diffusion is a process that allows ions or molecules

There are many variables one could look into‚ such as displacement‚ angle‚ damping‚ mass of the bob etc. The most interesting variable‚ however‚ is the length

Title: Diffusion throughout the membranes Lab Partner(s): Alexis Clouting Date: 2/15/15 Abstract: In the content of the Module 2 we learned about Diffusion across cell membranes. We touched on the different types of cells and their functions. How things are transported in and out of cells. Learning about isotonic‚ hypertonic and even hypotonic solution. This is not my first time touching on this subject in my nursing career and I learned a way to remember what happens in the different solutions

Experiment 1: Simple Distillation and Boiling Points- Separation of Liquids February 24‚ 2014 Analysis In this experiment‚ the distillation of three groups of two miscible liquids was performed. First‚ Ethanol and 2-Propanol were distilled. The boiling points of ethanol and 2-propanol had a difference of 5°C. The percent recovery for both ethanol and 2-propanol were both 0%. The percent recovery of the intermediate was 96%. The percent efficiency calculated of ethanol and 2-propanol was 0% efficient

Using distilled water in the right beaker and either the 100 MWCO or 200 MWCO membrane will remove urea from the left beaker and leave albumin If the left beaker contains NaCl‚ urea‚ and albumin‚ you can selectively remove urea by dispensing a concentration of NaCl into the right beaker equivalent to that in the left beaker and by using
