Osmosis Lab Report by Evan Gerber Claire Cambron First Lab Report Wednesday 10:30am February 20‚ 2013 Theresa Gburek Abstract The major objective of the experiment was to test the effect of the concentration gradient on the diffusion rate. It was hypothesized that the greater the stronger the concentration gradient‚ the faster the rate of diffusion would be. To test this‚ dialysis tubes were submerged in different concentration fructose solutions. We weighed the tubes at specific

Injectable Tissue Engineering INJECTABLE TISSUE ENGINEERING My part of the assignment is to provide a detailed history of Injectable Tissue Engineering. I must also provide details how Injectable Tissue Engineering affects the environment. Ttissue engineering has advanced dramatically in the last 10 years‚ offering the potential for regenerating almost every tissue and organ of the human body. Tissue engineering and regenerative medicine remain a flourishing area of research with many

When the Irish Potato Famine Struck Ireland On a sunny morning in 1845‚ Irish farmers were going to check their crops. A farmer named Abraham Fitz found black potatoes in his fields. He thought it may be only the one‚ so he moved over 4 rows and dug another potato out of the ground. This one was black and rotten. This causes Abraham to travel to his neighbors house and ask about their potatoes. His neighbor’s potatoes were black‚ rotten‚ and giving off a foul stench. This would later be discovered

different tissue types. Epithelial tissue is a sheet of cells that covers a body surface or lines a body cavity. For example‚ epithelial tissue can be found in the stomach. There are two different types of epithelial tissue; simple and stratified. The simple epithelial has a single cell layer‚ whilst the stratified epithelial consist of two or more cell layers stacked on top of one another. They are tightly packed tissues and the two types can be seen in the image below. Epithelial tissues have two

Potato Chip Monopoly ECO204: Principles of Microeconomics Instructor: A monopoly is an industry composed of only one firm that produces a product for which there are no close substitutions and in which significant barriers exist to prevent new firms from entering into the industry (Case‚ 2009). In a different definition‚ it can be distinguished by a lack of financially viable competition to produce the goods or services as well as to substitute goods. Monopolies often refer to a procedure

Principal tissues in the human body Colorado Christian University Human Anatomy/Physiology BIO201A Principal tissues in the human body The human body is contains four main tissue types. Tissues are a group of similar cells‚ formed in the embryo‚ that perform a specific function or group of functions. According to Patton and Thibodeau (2013)‚ “There are four major or principal tissue types: epithelial‚ connective‚ muscle‚ and nervous” (p. 8). Each of these tissue types differ in the roles

individuals with scars go a step further with removal of the scar tissue. Scar tissue is fibrous connective tissue which forms when skin tissue is damaged‚ typically forming when the body tries to heal the wound expeditiously. Scar tissue is constructed by same main protein as normal

Osmosis Osmosis is just a special case of diffusion - where water diffuses through a membrane which has different concentrations on either side. Permeable means "allows anything to pass through". Membranes in cells allow small molecules (water) to pass through‚ but prevent bigger ones from passing. This is called "selectively permeable". Take a look at the following animation; If a selectively permeable membrane separates the two solutions‚ water moves through it in both directions at

The purpose of this lab was to observe the rate of osmosis and diffusion‚ as well as the effect of molecular size of the particles on this rate. Part I of the lab was a demonstration of osmosis and diffusion‚ that dealt with raisins in different liquid environments‚ each with a different concentration of sugar. Part IV of the lab was using the same idea as the demonstration‚ by putting objects in different concentrations of a substance; in this case elodea leaves in salt water. In both cases‚ the
