Introduction The purpose of this lab is to find out which osmotic environment the eggs are in while sitting in different liquids. There are three different types of environments: hypotonic‚ isotonic‚ and hypertonic. Hypotonic solution causes the cell to swell until it bursts. Hypertonic solution causes the cell to shrink or to lose weight. Isotonic solution doesn’t cause the egg to shrink or swell‚ it keeps the cell the same it’s just in a different environment. The hypothesis for the egg in

molecules to diffuse though (Lab Manual 7e‚ 2010). Diffusion or osmosis occurs until dynamic equilibrium has been reached. This is the point where the concentrations in both areas are equal and no net movement will occur from one area to another. If two solutions have the same solute concentration‚ the solutions are said to be isotonic. If the solutions differ in concentration‚ the area with the higher solute concentration is hypertonic and the area with the lower solute concentration

efficient for transporting a variety of substance around the body. Ventilation: gaseous exchange is also a very important for exchanging materials. Oxygen and carbon dioxide are able to move easily between the lungs and the blood by diffusion. Gas and solute exchange surfaces in humans have been adapted to maximise their effectiveness. The larger an organism gets and the more complicated it is which makes it harder for materials to be exchanged. Gaseous exchange is the process by which oxygen is taken

Soaring Freely Symbols are more than what they appear to be. Their true meaning exposes an idea or meaning. A symbol is anything that means more than its literal meaning. In the novel The Awakening‚ Kate Chopin uses many symbols throughout the story such as the ocean‚ Edna’s passion for art and swimming to reveal more than its literal meaning. The Awakening follows a woman named Edna Pontellier who is tired of following the traditional standard in her society and slowly break free from its oppressive

Dialysis (Simple Diffusion). Which solute(s) were able to pass through the 20 MWCO membrane? None of the solutes were able to pass through the 20 MWCO membrane. A possible reason to why none of the of these solutes were able to pass through was because the solutes could have been too big to be transported. According to your results‚ which solute had the highest molecular weight? The solute that had the highest molecular weight was Albumin. Which solute displayed the highest rate of diffusion
