Josh P. AP Biology 12-10-13 Lab Writeup The Effect of Transformation of pGLO in Bacteria Background/Objectives/Hypothesis: Genetic transformation is a process that primarily is inserting new DNA into an organism to change that organism’s trait. This process has many useful benefits when used correctly in different organisms. In this lab‚ bacteria was transformed by inserting DNA for Green Fluorescent Proteins. The DNA for these proteins were taken from bioluminescent jellyfish Aequorea

Anatomy & Physiology I March 17‚ 2008 Lab Report- Fetal Pig The purpose of dissecting the fetal pig is to experience way the body looks internally. The fetal pig body organs are similar to the organs in a human body as well as the functions. My first step was to start cutting from the neck/cervical down to the midsection of the body. Then I cut the skin off so I can see the different muscles groups‚ such as the pectoralis major across the chest. However‚ I had to be very careful while

Labset Three Worksheet 1. What is a carbohydrate profile? Why are they used as a diagnostic or identifying tool? (2) Carbohydrate profiles are specific information on the type and amount of carbohydrate that a product contains. It is used to identify and differentiate two closely related species. 2. What are the carbohydrate profiles of the organisms you tested? (2) The yeast carbohydrate profile came out with glucose and fructose positive and Mannitol negative. The staph epidermidis

molecules of the food coloring equally distributed in the area of the water. Osmosis is a special type of diffusion where only the water molecules move. This happens through a selectively permeable membrane. It allows water and oxygen to move freely across the membrane. Osmosis only has an effect when the cell is in a hypotonic or hypertonic solution. A hypotonic solution is when the salt concentration
