Option A: Observation: During the winter‚ you spread salt daily on your driveway to melt the snow. In the springtime‚ when the lawn begins to grow‚ you notice that there is no grass growing for about 3 inches from the driveway. Furthermore‚ the grass seems to be growing more slowly up to about 1 foot from the driveway. Question: Might grass growth be inhibited by salt? My hypothesis is that the grass growth is being inhibited by salt. An average winter season last approximately five or

The story of potato chips dates back to late 1850s‚ when a New York chef presented deep fried crisp potato chips to the railroad tycoon Cornelius Vanderbilt. Although the invention was made out of curiosity‚ it became an instant hit after Vanderbilt gave it an approval. Till date‚ potato chips are one of the most favorite snacks among many Americans. To keep up with the healthy trend at present‚ many chips makers now have baked alternatives to traditional chips. Here are few choices of our top chips

Once known as the number one agricultural county in the nation‚ Los Angeles County houses nearly 10 million residents. This means the demand for consumable water is high‚ and with this demand comes depletion. Many areas of the Central and West Coast Basins are experiencing ground water depletion‚ which has resulted in an intrusion of saltwater in coastal aquifers‚ “natural filters that trap sediment and other particles (like bacteria) and provide natural purification of the ground water flowing through

Desalination of Seawater Project Paper The main concept of this Desalination process is reverse osmosis‚ but we will get into that later. Right now what is probably running through your head is what exactly is desalination. To put it simply desalination is the process to make seawater or otherwise undrinkable water safe to consume. This can be accomplished through a variety of methods such as the simplest but one of the ones that requires a lot of money would be distillation. Distillation is commonly

The process of osmosis and its importance to living organisms Osmosis is the process by which there is a net movement of water through a semi permeable membrane from an area of high water potential to an area of low water potential. Within a cell‚ osmosis has the following effect. If the water potential of the cell is lower than that around the cell water will move across a concentration gradient into the cell. If this is the case‚ the increase in water in the cell‚ may cause the cell to swell

Marisela Andrade The Effects of Salt Water on Gummy Bears Facilitated diffusion depends on passive transport. Molecules cross cell membrane by diffusion. A type of diffusion is osmosis. If no energy is input into the system during diffusion‚ the molecules will reach a state of equilibrium. The purpose of this experiment was to study why the death occurred among those who drank salt water. Two blue gummy bears had a height of 2 centimeters each. The mass of these gummy bears together were

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

Potato Juice Excellent Tonic: Skin Disorder: Angular cheilitis – One of the most important purposes of potato juice is for treating angular cheilitis‚ a common skin disorder characterized by redness and swelling of the mouth corners. Potato juice is known to be an effective anti-inflammatory so applying this on the corners of your mouth can tone down the lesions in no time. If you make it a habit to drink potato juice every day‚ you’ll get enough vitamin B complex‚ which you need to fight angular

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
