Practical Work Nº2: “Different methods to control osmosis” Aim: observe and test the process of osmosis through different kinds of methods: the weigh (potato)‚ the density (beetroot) and under the light microscope (onion). Hypothesis: according to the encyclopedia definition osmosis is the diffusion of a liquid (most often assumed to be water‚ but it can be any liquid solvent) through a partially-permeable membrane from a region of high solvent potential to a region of low solvent potential. Thus

Graphs are often used to deliver a visual and compelling case in many applications and businesses. Graphs are the information delivery vehicle of choice for many numerical data applications. With graphs a lot of information can be condensed into a visually descriptive object. They reduce the amount of time that would have been expended in reading or parsing through a lot of information. On the other hand‚ they can also be easily used to misrepresent or skew interpretation towards a favorable

The least designation for his budget will be for his savings which has 5% only. 2. BAR GRAPH The bar graph shows the yearly tourist count for the provinces of region V. the province of Albay got the highest number of tourist with 450 000. It is followed by the provinces of Camarines Sur and Camarines Norte with 400 000 and 350 000 respectively.

Osmosis in Plants Outline: To investigate the effect of varying concentration of a certain sugar solution on the amount of osmotic activity between the solution and a potato chip of a given size. Definition - Osmosis: Movement of a solvent (liquid) through a semi-permeable membrane separating solutions of different concentrations. The solvent passes from a less concentrated solution to a more concentrated solution until the two concentrations are equal. All

Graphs 1 Introduction We have studied one non-linear data structure so far i.e Trees. A graph is another non-linear data structure that is widely used to solve many real-life computing problems. For example‚ we need to use a graph to find out whether two places on a road-map are connected and what is the shortest distance between them. Graphs are used in simulating electrical circuits to find out current flows and voltage drops at various points in the circuit. Graphs are widely used in telephone

concentrated area to a low concentrated area. Water is one molecule that can diffuse freely in a cell. Other molecules need assistance through the cell membrane through a process called facilitated diffusion. Osmosis moves from an area of low concentration to high concentration. In osmosis water moves in the opposite way. Water flow is determined by the concentration‚ not the nature of the solute. There are a couple of things to consider for diffusion to work. The size of the cell‚ permeability

EXPERIMENT OBJECTIVE The objective of this experiment is to develop an understanding of the molecular basis of diffusion and osmosis and its physiological importance. Students will analyze how solute size and concentration affect diffusion across semi-permeable membranes and how these processes affect water potential. Students
