Investigating the water potential of a potato Aim Osmosis is the movement of water molecules from a region of high water concentration to a low water concentration through a semi-permeable membrane. Our aim is to investigate the water potential of a potato through osmosis‚ by finding the difference in weight before and after the potato has been set in a solution of water‚ sugar or salt. Trial Method Firstly we collected the equipment. This included a scalpel‚ potato cutter‚ and test tubes. Then

When something is added to the environment which is very harmful‚ poisonous or fatal to the animal‚ people surrounding it and other living things is called as pollution. In simple term pollution is a contamination by a chemical or other pollutant that renders part of the environment unfit for intended or desired use. It is triggered by industrial and commercial waste‚ agriculture practices‚ day to day human activities and most notably‚ modes of transportation and many the other sources. Pollution

Investigating Chemical Equilibrium Date: 30th April 2013 Due Date: 15th May 2013 Prepared For: M. Seraji Prepared by: Andrea Odunze Abstract Many reactions proceed to a state of equilibrium. A chemical reaction at equilibrium‚ where the rates of the forward reaction and reverse reaction are equal‚ looks like this: A + B AB There are three factors‚ according to Le Chatelier’s principle‚ that affect the equilibrium position and equilibrium constant. These are the concentrations of products

eInvestigating water potential of swede The aim of our experiment was to investigate the water potential of swede and then use our results to help us determine the water potential of plant tissue. This overall flow of water from a dilute area of high water potential to a more concentrated solution of low water potential across a partially permeable membrane is called osmosis. I predicted that the swede cylinders which are put in a test tube with a low potential of sucrose solution would become

The Environmental Impact 95 percent of electronic waste is recyclable. However‚ unregulated recycling can cause more harm to the environment than landfilling. While many companies‚ such as Apple‚ have safe and effective recycling programs‚ the majority of recycling companies export some percentage of their electronic waste to China or poor countries in Africa‚ where the waste is “recycled‚” or destroyed and stripped of its valuable metals. Though this seems like a good thing on the surface‚ because

We as human beings are very fortunate to be living on this planet that we call Earth. We toil over the land‚ and in return we receive provisions off of which we live. Even though we get all that we need from this bountiful land‚ we still for some reason feel like we need to alter it. In doing so we also end up ruining the land that we thrive on. We reshape the world to fit our individual needs‚ and the earth just doesn’t work that way. Everything on this planet has a purpose‚ from the largest animal

Environment Culture influences an individual’s attitude towards environment. Environment in this context refers to our physical surroundings and nature. Man’s attitude towards his immediate environment is largely based upon his cultural upbringings. Trompenar’s concept of attitude towards environment highlights how man controls nature by imposing his will upon it (reference). Large organizations impact the nature and environment in many ways. Corporate Social responsibility has become
