concentration to an area of low concentration across a semi permeable membrane. An osmotic system is established when a semi-permeable membrane is placed between two solutions. In this biological systems context‚ osmosis is the exchange of water between the potato cell and the surrounding medium of varying sucrose concentrated solutions‚ with the plasma membrane being the semi- permeable membrane. Because water molecules have kinetic energy‚ they are constantly moving around in gaseous or liquid form‚ moving

GCSE Biology: Osmosis in a Potato Aim To investigate the effect of placing a piece of potato in a given strength of sugar solution. Prediction I predict that‚ as the solution becomes more concentrated the more the cell will shrink‚ as the water‚ of higher concentration inside the potato cells‚ flows down a concentration gradient into the solution‚ which has a lower concentration of water molecules. If we say that the percentage change when the potato is placed in the 1M solution is x%. I predict

The Gathering of Space-Gypsies By A.C. Johner In the summer of 2003 I was living in Dublin. At nineteen years old‚ it was my first time out of the United States‚ and I had left with latterly nothing but a spoon‚ toothbrush‚ a knapsack filled with science fiction novels‚ and something like 1000 dollars to live off of for the next three months. I spent my first month living in this run down hostel for only forty dollars a week in what I suppose was the seedier side of Dublin.

The Gathering Storm by Winston Churchill War has always been a part of human life and the growth of every country in the world. It was either war between two or more countries or war within the country. Some countries fought to gain independence‚ some start a fight as a payback to the assassination of their heir throne‚ some fight to expand its power and some just fight because they are allies to a country at war. No matter what the reason of war is‚ war has left a great impact on how things are

The potato’s introduction into Europe proves to be one of the most significant examples of a foreign food crop being able to extensively affect the lives of a an Old World Population. Before the assimilation of the potato crop into the majority of Europe’s agricultural landscape‚ peasant populations constantly faced famines while current food sources provided little nutritional value and were not efficient sources of energy. As Europe adopted the brown tuber‚ people were provided with a far more

water either into the potato cells or out of the potato cells. In the 0.400M solution‚ the potato decreased in mass‚ this was due to the reason that the solution was hypertonic. There was a higher concentration of solute and lower concentration of water in the solution than there was in the potato cells. This led the water to travel down its concentration gradient‚ which was from a higher concentration (in the cell) to a lower concentration (in the solution)‚ which meant the potato cells lost water‚

Making a Potato Powered Light Bulb Materials: A large potato Two pennies Two zinc-plated nails or screws Three pieces of copper wire A very small light bulb or LED light 1) Get a potato and cut it in half. Then make a small slit in each half just big enough to put a penny into. 2) Cut two pieces of copper wire and wrap one around one of the pennies a few times‚ and wrap the other one around the other penny a few times as well. 3) Take a third piece of copper
