difference in the osmolarity‚ no change in the cells sizes. PART 3 Procedure: 1. Repeat step (1 – 3 of PART 2) using 30% of sucrose solution. Results & Observations: In the hypertonic solution we can notice the shrinking of the cell membrane due to the loose of water. Discussion & Conclusion: Water will move in or out of the onion cells according to the concentration of sucrose in and out of the onion cells: in an isotonic solution no change will happen; in a hypertonic solution

Investigation of Water Potential in a Root Vegetable Introduction Background Information: Osmosis is the passage of water from a region of high water potential to a region of low water potential‚ down a water potential gradient through a semi-permeable membrane. If a plant cell‚ or an item with similar properties is put in water‚ three different things can happen: • If the surrounding area has a higher water potential‚ the cell will increase in mass through osmosis. The cell will

concentration in electrolytes on the potential difference in a voltaic cell Introduction When two electrodes made of different metals are connected together in a voltaic cell‚ the chemical energy present is converted into electrical energy and an electromotive force is generated. This force‚ called the electrode potential‚ is normally measured under standard conditions‚ which is 298K‚ 1 mol dm-3 solution for the electrolyte. However when one measures the electrode potential in a voltaic cell‚ the conditions

Based on Criteria’s of Evaluating Venture Opportunities there are several key indicators that shows that Zipcar is indeed a high potential venture. Below are the criteria in brief 1.0 Industry & Market Market: The revolutionary concept certainly provides an alternative to public transport. Furthermore the car sharing concept is really useful for the public in a overcrowded city with limited parking & expensive parking fees. This is clearly not an untouched segment because there are other 2 competitors

I. Introduction 1. MARKET POTENTIAL ANALYSIS The Concept of market Potential It is defined as the maximum demand response possible for a given group of customers within a well-defined geographic area for a given product or service over a specified period of time under well-defined competitive environmental conditions. We will further split up this definition: 1. Market potential is the maximum demand response under certain assumptions (ultimate demand). 2. Relevant customer

The Changes of Heart Rate of Students during Human Dive Response when Resting and Submerged Abstract The dive response is known more popularly as a mammalian dive reflex. It is a survival mechanism built into mammal’s bodies‚ essentially. Over the years‚ scientists have been determined to find what triggers mammals to have a decreased heart rate when submerged under water allowing them to stay under the water longer when they do not typically live under water. In this experiment‚ we tested

Extra-Corporeal Membrane Oxygenation (ECMO) is a life-saving treatment for severe respiratory failure irresponsive to mechanical ventilation‚ associated or not with haemodynamic instability‚ and its application fields are widening to refractory sepsis and also to elective thoracic procedures. ECMO is replacing conventional cardio-pulmonary by-pass (CPB) even during lung transplantation due to its potential advantages: the absence of full-anticoagulation and the possibility of maintaining the extra-corporeal

1. Searching for potential life on exoplanets Despite the rapid improvement in technology the past few years‚ the current technology is not capable of yielding a completely successful mission that would travel to other stars and search for habitable exoplanets. Fortunately‚ the number of solar systems and exoplanets discovered is increasing. Direct images received from those exoplanets have a very low resolution but provide plenty of useful information. This essay will examine how this information
