Anjali Patel Riley Egan‚ Nick Morrison 10/2/13 Block 2 LAB REPORT OUTLINE FOR DIFFUSION/OSMOSIS LAB Introduction: Diffusion is the net movement of small or uncharged molecules or substances from areas of higher concentration to areas of lower concentration. There is simple diffusion‚ as explained‚ and facilitated diffusion. Facilitated diffusion‚ on the other hand‚ involves larger or charged molecules or substances that need a protein tunnel through the membrane to help the substance enter and

Seamus Heaney – ‘At a Potato Digging’ • Context • • The poem deals with two different potato harvests. One is the harvest from the present day that goes successfully and which delivers a rich crop. The second potato harvest looks back to the famine of 1845 when the crop failed and many people starved. Whilst the famine is no longer a threat‚ its ongoing fear remains and this can be seen in the use of religious language throughout the poem. For example‚ the bowed heads of the potato pickers suggest the

The Effect of Concentration Gradient on Osmosis Abstract: Osmosis is the passive movement of water from an area of higher concentration to an area of lower concentration‚ usually across a membrane (Thorpe 2013). Tonicity is the ability of a solution surrounding a cell to gain or lose water (Reece 2011). There are many factors that affect the rate of osmosis. These include temperature‚ surface area‚ difference in water potential‚ pressure‚ light and dark and most importantly what we will be talking

The Irish Potato Famine Have you ever thought that one day all of the potatoes could go bad? Unfortunately it’s true.The potato famine or known as the Great hunger was in Ireland until 1845-49. People of all ages were affected.Since the soil was poor‚ potatoes didn’t grow like they’re supposted to. The cause‚ a failure of the Irish potato crop due to an infestation of Phytophora infestans‚ a microscopic fungus‚ also called the potato blight.They think that the disease was brought him by an American

Diffusion‚ Osmosis and Active Transport Substances will move through the membrane by diffusion. This is the random spreading out of particles until they are even. For example‚ when you put your instant coffee in boiling water‚ the coffee particles spread out and fill the entire mug‚ this is diffusion. A second way that substances can move through the cell membrane is by osmosis. This is a special type of diffusion where water moves from a high to a low concentration through a ’partially permeable

It was not until almost two hundred years later that the process of osmosis was revisited and extensively reviewed by researchers from the University of California at Los Angeles. In 1959‚ Sidney Loeb and Srinivasa Sourirajan developed a membrane made from cellulose acetate‚ which removed at least ninety percent of salts

A potato chip is a slice of potato‚ deep fried or baked until crisp. Potato chips serve as a side dish or snack. The chips of this kind are just cooked and saled‚ but chips are an important part of the snack food market in English-speaking countries and many other Western nations. Lays Classic potato chips contain potatoes‚ healthier oil‚ and salt. Consumers buy lays classic potato chips because of the fufilling taste‚ crunchy and salty.
