Aim The aim is to find the concentration (mole/dm3 (M)) of solute in a potato cell by using the process of osmosis and different concentrations of sucrose solution. Background information Osmosis is diffusion of water across a partially permeable membrane. It moves from a solution with less solute concentration (high water potential) to a solution with more solute concentration (low water potential). The one with a high water concentration is called a hypotonic solution and the low water concentration

Key Notes: Space Tourism is the term that’s come to be used to mean ordinary members of the public buying tickets to travel to space and back. Many people find this idea futuristic. But over the past few years a growing volume of professional work has been done on the subject‚ and it’s now clear that setting up commercial space tourism services is a realistic target for business today. But this idea of Space Tourism isn’t at all familiar to most people‚ including the space industry‚ who are used

Urban Spaces Living within a unicultural community is quite the norm for many reasons. It serves a plethora of benefits to be surrounded by individuals who share the same lifestyle as you. The corner grocer may stock ethnic foods particular to your own culture that could not be found in major chain stores. Your neighbors may speak your native tongue if you’re not from that particular part of the world thus eliminating language barriers. All these small conveniences associated with living in unicultural

I. The Irish Potato Famine was a catastrophic event in Irelands history. Almost a million people died during this harsh time. They had lost their main food source and barely had food for one person let alone their families witch consisted of 5-7 people on average. At the time they were considered a part of Britain but Britain did not help much during their crisis. The Irish Potato Famine of Ireland in 1845 resulted in a great population loss‚ a changed economy‚ and a substantial emigration of citizens

Experiment: Turgor in Potato Tissue 1. We labelled three test tubes A‚ B‚ C‚ D and added initials of people in our group. 2. Used a syringe or graduated pipette to put 20 cm3water in tube A and 10 cm3 in tube B. 3. Put 20 cm3 of 17% solution in tube C and 10 cm3 in tube B; put 20 cm3 pure sucrose solutions in tube D. 4. Working on the dissecting board I cut the ends off large potato. I was careful with the knife and cut it onto the dissecting board away from myself. 5. Used a cork

CHAPTER 1 INTRODUCTION Every day of your computing life‚ you reach out for the mouse whenever you want to move the cursor or activate something. The mouse senses your motion and your clicks and sends them to the computer so it can respond appropriately. An ordinary mouse detects motion in the X and Y plane and acts as a two dimensional controller. It is not well suited for people to use in a 3D graphics environment. Space Mouse is a professional 3D controller specifically designed for manipulating

Potato Osmosis Introduction: A shipwrecked sailor is stranded on a small desert island with no fresh water to drink. They know they could last without food for up to a month‚ but if they didn’t have water to drink they will be dead within a week. Hoping to postpone the inevitable‚ their thirst drives them to drink the salty seawater. They are dead in two days. Why do you think drinking seawater killed the sailor faster than not drinking any water at all? Today we explore the cause of the sailor’s
