The pGLO lab is a lab where students attempt to put the genes that make a jelly fish glow into E. Coli. After a process called transformation‚ the process in which a cell takes up and expresses a new piece of genetic information‚ the E. Coli will be able to glow and will be antibiotic resistant. The students first need to learn a couple of techniques before they are able to begin this lab. The first technique they will need is how to keep their environment sterile. They must learn to only open their

I.Purpose The purpose of this lab is to show how potential energy and kinetic energy is shown and transferred using a model rollercoaster. This lab also demonstrates the Law of Conservation of Energy. II.Introduction Potential and Kinetic energy have a very big relationship. The Law of Conservation of Energy states that “Energy cannot be destroyed or created‚ but can be transformed or transferred.” This lab will help demonstrate this law and show the conversion between Kinetic and Potential

This ensures variety of soil to ensure that all the site is safe‚ not just a small area where you would have taken your first sample from. I will return to the lab with the samples of soil I have extracted from the site. Here I will make a solution from the samples in order to carry out the identification tests.

flame the loop or wire before you begin to sterilize it. Then you remove the caps from the tubes and flame the mouths of the tubes to prevent air-borne contamination. Next‚ you have to pick up the inoculums or unknown culture by running the sterile loop or wire down into the tube. Once you get the inoculums‚ you drop it into the sterile medium to inoculate it. 2. What is the purpose of aseptic technique? Answer: It prevents contamination from unknown cultures. 3. Does your lab report contain

Toxicology Lab 1. In this investigation‚ a wide range of concentrations of Sodium Chloride (NaCl) solution were created and the effects that they had on radish seeds were tested. This ultimately created a doseresponse experiment in which it was detectable whether or not radish seeds were a reliable bioassay for the toxicity of NaCl. The goal of this experiment was to determine a correlation between toxicity and seed germination/radicle

cladograms. In this study‚ we observed the difference between cladograms created with morphological traits and molecular DNA with respect to Felis cattus‚ Canis familiaris‚ Didelphis virginiana‚ Odocoileus virginianus‚ and the Equus caballus. The results demonstrated that although a species is similar or closely related in regards to morphological traits‚ it does not mean that their DNA composition will be the same. This study is significant because it demonstrates the importance of phylogenetic systematics
