When you think of the word "drug" what comes to mind? Probably marijuana‚ cocaine‚ lsd‚ prescriptions but what about bath salts? When I first heard stories about people on bath salts my reaction was you have to be kidding right‚ but no first popping onto the radar of the DEA and poison control in 2010‚ this product is causing quite a stir in the United States. Mark Ryan from the LA poison control says in an interview on the Dr. Oz television show "that he has never seen a drug that has caused the

Formal Scientific Lab Report Osmosis Katy Hunter 10-26-2012 Abstract: The objectives of this lab was to be able to create models of cells with the dialysis tubing to show us how the plasma membrane is selectively permeable‚ to study the effects of osmosis on a model cell‚ and to foresee the effect of solute concentration on osmosis. In order to achieve these objectives‚ we had to fill the dialysis tubing with either water‚ or different amounts of sucrose. We then tied off the tubes and put

their fair share and more. Yet this sadly is not the case‚ as the majority of the water on Earth is unsuitable to drink due to the fact that it is tainted with a numerous amount of contaminants‚ such as bacteria and salt. The amount of safe drinking water is decreasing more and more each year and will soon become one of the more scarce resources on the planet. Over the years‚ many different people all over the world have tried to create and refine a water purification process that is both effective

describe revision is about vocabulary‚ suggesting that they “understand the revision process as a rewording activity”. How is that different from the way she argues that revision should be understood? Nancy Sommers studies the problem of revision between students writers and more experienced writers. Those writers who are students focus more on the revision as fixing small errors and textual repetition‚ when more experienced writers focus on revision more generally‚ not only on the repetition of the

The Differences Between Domestic Violence and Family Violence Ema Reynoso Humphreys College The legal definitions of domestic violence and family violence vary from state to state. To better understand the difference between domestic violence and family violence‚ we must determine the context in which the phrase is used. Equally important‚ it is necessary to define the individual forms of abuse associated with domestic violence and family violence. Common forms of abuse include physical abuse

However‚ in Scrum‚ there is a group which works on the project to achieve its aim. It works in full coordination with each other and comprises of professionals including software developers‚ product owners and experts from various fields. The basic difference between Project Management Professional (PMP) and Scrum is that the former tries to plan everything direct and straight‚ the later can bring about changes in the project during the process of development. This is rather a complex procedure and

This energy causes molecules to bump into each other and move in new directions. Diffusion is one result of this molecular movement. Diffusion is the random movement of molecules from an area of higher concentration to areas of lower concentration. Osmosis is a special kind of diffusion where water moves through a selectively permeable membrane that only allows certain molecules to diffuse though (Lab Manual 7e‚ 2010). Diffusion or osmosis occurs until dynamic equilibrium has been

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

Diffusion and osmosis are processes that are a constant in our lives‚ even though many don’t realize it. Medicaments such as Fervex can be drunk only after diffusion has taken place and the powder granules have diffused into the hot cup of water. On the other hand‚ every day we become unintentional witnesses of osmosis when the roots of the plants try to suck up the water from the soil (1). The purpose of this lab is to show clearly in an understandable way how diffusion and osmosis happen and to

The purpose of this lab was to model the significant differences in density that oceans experience when glaciers and polar ice caps melt. It demonstrated that the variation in density greatly affects salt water. I discovered that the increase in freshwater causes a decrease in density. I made three claims. First‚ the higher the salinity of the water is‚ the denser it will be. This was shown in my data by the fact that‚ with 0mL of fresh water‚ the density was 1.108 g/mL For every milliliter of fresh
