molecules in or out of their membrane. Some require no energy to do so (passive transport) while others require energy to be processed through (active transport). There is also the transportation of water across a membrane‚ which has its own term of osmosis. Too much of something can be taken in‚ or too little enters. This especially happens to plants‚ who require water (and sun) to live. Not enough water‚ as herbalists or any plant lover will know‚ will cause the plant to wilt. However‚ why consider

Investigating the Water Potential of a Potato. I have been asked to investigate the water potential of a potato. During my investigation I will not actually be able to measure a value for‚ as it is a pressure value (kPa). Osmosis is a special form of diffusion involving only water molecules. It is defined as "The passage of water from a region of high water potential to a region of low water potential through a partially permeable membrane" Definition of Water Potential. The potential for water

Question 3: What is reverse innovation and what role do you see it in playing in GE’s future? Reverse innovation is a term to describe products that are designed in the emerging markets and subsequently being sold globally. Figure 1 indicates a tremendously change in GE’s revenue sources. This signifies a successful international expansion. Figure GE Total Revenue by Region Source: Compilations – Case Studies on Strategic Management‚ Case 19-Healthymagination at GE‚ pp 262 & Exhibit 10a.

The Reverse Marketing Framework: Case Malston Bakery Inc. Summary of the case: John Thomas is the Director of Purchasing of the Malston Bakery‚ a major bread producer. He feels really concerned by the augmentation of the costs generated mainly by important increases in flour prices‚ which represent 55% of the total cost of bread production. John Thomas has no results by negotiating purchasing prices with the six main flour mill suppliers‚ despite some repeated attempts. So he decides to conduct researches

Investigation into finding out the Effect of the effect of osmosis In potato cells Introduction I am doing an experiment to find out the effect that osmosis has on Water solution and a Sugar solution. Osmosis is a process which water moves from an area of low concentration to an area of high concentration. I am going to record my results to see if osmosis occurs in water solution of sugar solution. Apparatus In this experiment I would need; - 1) 3 test tube 2)

Membranes allow the diffusion by letting certain molecules pass through it. Small pores in the semi (selectively) permeable membranes‚ which flow only towards one way‚ allow the process of osmosis to continue. These pores let only tiny molecules to go through them. One example might be the dialysis tubing in which a membrane made of a regenerated cellulose fibers formed into a flat tube. If two solutions containing dissolved substances of different

IB HL BIOLOGY Dialysis Lab: Exploring Osmosis and Diffusion Through A Membrane Introduction: Dialysis is the flow of certain solutes through a semi permeable membrane. Dialysis is usually used on patients with failing kidneys to clinically purify blood in their kidneys‚ or other regions of their bodies. The dialysate contains waste matter that flows from the blood our of the dialysis tubing. Question/aim of lab: To test the solutions inside and outside the dialysis tubing with Benedict’s
