Date: 28/11/13 EVALUATION OF THE EFFECT OF SODIUM CHLORIDE ON ONION EPIDERMAL CELLS INRODUCTION A living plant cell will shrinks or swells depending on the solute concentration of the cell in relation to the solute concentration of the fluid surrounding the cell (1). It follows that water will move from a region of high water concentration to a region of low water concentration therefore‚ if a cell is placed in a hypertonic solution water will move from the cell into the solution until the

partially supported because glucose left the bag and is proven by the positive test on the surrounding water. Also the beaker turned orange because of osmosis which attests to glucose leaving the bag. Iodine Potassium Iodine and water entered the bag. This was proven by the color change in the starch test as the bag turned black also because of osmosis. The only thing that the hypothesis lacked was that starch did not move at all. The beaker stayed yellow before and after because the bag is not permeable

Phillip K Dick’s "Do Androids Dream of Electric Sheep?” ‚ Mikhail Bulgakov’s "The Fatal Eggs" and Franz Kafka’s "The Metamorphosis" each explore the connection between empathy and what it means to be human through a critique of their respective societies‚ challenging the assumption that humans have a morally superior standing. By critiquing their socio-political contexts‚ these texts question the extent of empathy humans have‚ pushing the boundaries between the human in relation to either the animal

The media is about paying for egg freezing for female employees until they are ready to become parents.

Them paying for women to freeze their eggs can help resolve those problems by pushing women’s fertility into the future. One way that this is all consistent with symbolic

Introduction: In this experiment‚ you will study osmosis. Your task is to design an experiment that will determine what concentration of solute is isotonic with the specimen cells. (Design) Procedure: You will be provided with the following materials: Potato‚ potato corer‚ scalpel‚ forceps‚ electronic balance 10 % salt solution‚ distilled water‚ 50 mL beakers‚ graduated cylinder‚ paper towel You must design a procedure that will enable you to determine the concentration

Lab Report INTRODUCTION: This experiment is being done to find out what happens to a carrot or a potato if you place them in two different solutions. Osmosis has a lot to do with this experiment and is the movement of water molecules from a higher concentration to a lower concentration. Osmosis only deals with water and is a type of diffusion. The difference between all three solutions is that in a hypertonic solution the cells fluid rushes out of the cell and causes it to shrivel. In a hypotonic
