Genetically Modified Foods: Harmful or Helpful? (Released April 2000) by Deborah B. Whitman Genetically-modified foods (GM foods) have made a big splash in the news lately. European environmental organizations and public interest groups have been actively protesting against GM foods for months‚ and recent controversial studies about the effects of genetically-modified corn pollen on monarch butterfly caterpillars1‚ 2 have brought the issue of genetic engineering to the forefront of the public

Potato Lab Background information: A hypertonic solution is a concentration that is higher than the solution. A Hypotonic solution is a concentration that is lower than the solution. An isotonic solution is a concentration and solution that is the same amount. Hypothesis question: What will happen if you put a potato in hypertonic solution? What will happen if you put a potato in hypotonic solution? What will happen if you put a potato in isotonic solution? Hypothesis statement: If you

of Osmosis on a Potato Cell October 12th 2012 Osmosis Lab Purpose: The purpose of this lab is to investigate the effects of osmosis on a potato cell as it is immersed for a period of time in solutions of different water concentrations. Hypothesis: If the potato is immersed into the distilled water‚ then it will be the heaviest out of the three. This is because water is at the lower is moving toward the area of higher concentration‚ which in this case is the potato. This solution

You ever wanted a nice baked potato that you can make up any kind of way that you like and have whatever toppings you like? Well you will love my Potato Parlor. Potatoes are definitely America’s favorite vegetable. Did you know that every year we consume about 140 pounds of potatoes per person? Europeans have us beat‚ though. They consume twice as many spuds as American potato lovers! (Potato Fun Facts). Potato Parlor will not only have baked potatoes but French fries‚ grilled sandwiches‚ sweet potatoes

Osmosis in Potato Cells Interpretation My results show what I predicted would happen. My prediction was that as the concentration of sucrose increased the amount of water moving in or out of the potato would change. A low concentration of sucrose solution would make the potato increase in length and mass (become turgid). A high concentration of sucrose solution would make the potato shrink (plasmolysed) We can see this occurred‚ as at 0.1mol of sucrose solution the potato’s size increased by an

differentially permeable membrane. Therefore‚ potato cells‚ with their differentially permeable membrane‚ are selected as the medium for studying osmosis in this experiment. In this experiment‚ strips are cut from the same potato and placed in sucrose solutions with different concentrations to see if there are any changes in term of weight. Different concentration of sucrose solution is the independent variable while the volume and length of each potato strip and the amount of sucrose solution used

Potato Osmosis Biology SL - ATh INVESTIGATION “Potato Osmosis” INTRODUCTION Osmosis is a process that occurs at a cellular level that entails the spontaneous net movement of water through a semi-permeable membrane from a region of low solute concentration to an area of high solute concentration in order to equalize the level of water in each region. Involved in this process are hypotonic‚ hypertonic and isotonic solutions. A hypotonic solution is one with a lower osmotic pressure‚ indicating
