An investigation how sugar solutions of different concentrations affect osmosis. Research Osmosis is the diffusion of water across a partially permeable membrane from a dilute solution to one of a higher concentration. If a solution has a low concentration then the amount of (in the case of my investigation) sugar‚ the solute‚ will be low and the solution will be weak. If there is high amount of sugar then the solution will be concentrated (have a high concentration). When two solutions

Introduction Aging is an inevitable process and therefore it is important to know exactly what implications it has on ones’ nutritional health. The nutritional status of an elderly patient is very critical‚ as they are at a high risk for malnutrition. As their bodies change‚ they may find themselves with a micronutrient deficiency that they have never had before. This is because of the DRI’s changing for each age and gender group. The elderly has to focus on maintaining their lean muscle mass whilst

The purpose of the experiment conducted was to observe if a higher concentration or lower concentration gradient would affect the diffusion rate of the iodine moving through the starch concentration. This was shown to be an accurate experiment as with a higher concentration gradient the diffusion that did occur happened a lot faster and diffused more efficiently compared to no iodine solution and just water. This is due to the molecular collisions speeding up the experiment in the time period given

There is a link between terrorism and tourism but it is not simple. Terrorism does not seem to have a big effect on domestic tourism but mostly affects international tourism. If a host country has had widespread media attention to a terrorism event‚ tourist numbers see a major drop from selected areas. Low level terrorism gradually reduces tourism over a period of time‚ and surprise‚ brutal attacks have an immediate negative impact. The prevalence of violence is more important than the enormity of

Enzyme Activity How does temperature affect enzyme activity? In this practical investigation‚ my aim is to discover how temperature will affect enzyme activity‚ by looking at the rate of reaction. I predict that the higher the temperature will be‚ the faster the reactions take place. However‚ I also think that there will be an optimum temperature‚ at which the reaction will work at its fastest; if the temperature goes beyond that‚ the reactions will stop altogether as the enzymes would have

Teen literacy has been changing a lot during the past couple of years. It has really affected the age categories from 12-18 year olds. This affect stays with people through out their lives and affects adults as well. There are cures but they do take a while to work. If people don’t practice the cures everyday then they will not be as effective. Teachers have noticed many grammar mistakes in children’s writing and on their homework. It is the teachers responsibility to correct the children’s mistakes
