Egg Lab Report Introduction: An egg is a model of a human because the egg has a cell membrane like humans do inside and outside of the body that let things pass through like water. We can use eggs to study the effect of changes in the external environment on the internal environment by having harsh environments like putting the egg in only alcohol and see what happens to the inside of the egg. Diffusion is the movement of a substance down its concentration gradient from a more to a less concentrated

The purpose of this lab was to observe osmosis in the Gummy Bears and to investigate the movement of water in and out of a Gummy Bear. The hypothesis stated that the salt will make the gummy bear weigh more‚ but it will keep the gummy bear more intact. However‚ the results showed that the gummy bear decreased in mass because of the salt and water. This contradicts the hypothesis because of how it was believed that the gummy bear would increase in weight‚ but it did the exact opposite. One part of

Diffusion And Osmosis Abstract In this Diffusion and Osmosis lab a total of three experiments were performed. For experiment 5.1 we investigate diffusion through a selectively permeable membrane and the many factors that influence the rates of diffusion. In experiment 5.2 we investigate both animal and plant cells in different molar solutions and the different osmotic behaviors within the cells. In experiment 5.3 we test the osmolarity of plant cells through the usage of potato tuber cells

Introduction! ! The Michelson Interferometer is commonly used to determine the wavelength of light or measure very small distances. It was invented by Albert Abraham Michelson and is commonly used in optical interferometry‚ a branch of physics involving a family of techniques one could use to extract information about waves by superimposing them. ! ! The original application of the Michelson Interferometer was to the famous Michelson-Morley experiment in 1887. Prior to Einstein’s

ADI Lab Report Every living thing is made up of cells. All cells have some part in common. Some multicellular cells are highly specialized and carry out some very important functions. One of the special cells are red blood cells‚ their functions‚ transporting oxygen from the lungs to the cells in the body. Red blood cells look like little discs. Red blood cells can change their shape‚ this ability allowing them to squeeze through capillaries without breaking. Our task is to Design and carry out an

Using dialysis tubing to model diffusion of a cell membrane and investigating the influence of solute concentration on osmosis Purpose * Discover how dialysis tubing diffuses the cell membrane * Explore the effect of solute concentration on osmosis Background A cell membrane is a very significant function in the human body. In one sense‚ it is used as a barrier to keep the enzymes‚ DNA‚ and metabolic pathways that bundles everything together. Cell membranes are also used as a gateway
