REVERSE BRAIN DRAIN- A CONTRIBUTION TO INDIAN ECONOMY India is on the brink of an economic upturn as the phenomenon of brain drain has taken a role reversal in the last decade. The crème of the country’s management and technical acumen left due to inadequate opportunities and working conditions. Now‚ the stage is set. The world is watching as India experiences the most exciting phase of economic growth. As per the recent UN Development Programme report of 2001 as many as 100‚000 professionals

How is Osmosis Affected By the Concentration PLANNING Independent Variable The independent variable in this experiment is the thing that I will be changing in the experiment. This is the range of concentrations that have been obtained by diluting the original 1M solution of Sucrose. This is therefore the only thing that is going to be altered as I am investigating how different percentage of water molecules affects the weight of the the potato thus the rate and direction of osmosis.

The Effect of pH on the Rate of Osmosis Using a Glucose Solution Melissa Werderitch Biology 157 11/6/06 Introduction In a journal article written by Florian Lang‚ osmosis is essentially explained as the flow of water from one area to another that are separated by a selectively permeable membrane to equalize concentrations of particles in the two locations (Lang‚ 1997). Osmosis is able to maintain osmotic pressure and regulate a cell’s volume. In a hypotonic () or hypertonic () environment

Diffusion and Osmosis in an egg Low concentration 1.1 Diffusion is the process of molecules spreading from areas of high concentration to areas of low concentration. High concentration 1.1 Osmosis is the diffusion of water molecules through a semi-permeable membrane from the area of low concentration of solute to the area of high concentration of solute. 1.2 Diffusion is important to living cells because it’s the way they take in materials from the environment‚ and they also prevent themselves

Oppression is a significant issue that has been growing in discourse as of late. As time progresses‚ the way people are treated and the opinions they hold change. When there is a group of people who have their rights changed‚ it will cause other groups to believe they are being cheated out of chances the privileges those people are allowed access to. While this may be accurate in rare cases‚ it is also difficult to argue strongly on the side of the people who have been‚ and still are considered

Lab Activity No. __ Diffusion and Osmosis I. Introduction Diffusion is the transfer of molecules (or ions) from an area of higher concentration to a lower concentration‚ while osmosis is the transfer of water from a higher concentration to a lower concentration. II. Objectives 1. Demonstrate diffusion and osmosis across membrane. 2. Examine the relation of membrane permeability to diffusion and osmosis. III. Materials 2 thistle tubes‚ 2 big beakers‚ 4 tube clamps to fit iron stands

| Stage 2 Biology | | Adelaide High School | [Osmosis Practical Report] Abstract: | The purpose of this investigation is to see if the concentration of Sodium chloride (NaCl) solution will affect the mass of the potato cylinder hence the rate of osmosis. This can be done by placing 5‚ identical in length (3cm) but different in weight‚ tubes of potato in 5 different beakers. Each containing an altered NaCl concentration. The concentrations used in this experiment were‚ 0%‚ 2%‚

Osmosis Coursework How does the amount of sugar in a water solution affect the process of Osmosis in potatoes? Introduction In this experiment‚ I will be looking to investigate the effect of varying concentration of a sugar solution on the amount of osmotic activity between the solution and a potato chip of a given size. The potato chips were cut to size‚ then added to a water based sugar solution‚ where the variable was the amount of sugar added. The potato chips were cut to size by a potato
