October 13‚ 2012 Needle through a Balloon Pre-Lab Preparations: Purpose: The purpose of this experiment is to see if the balloon pops when pierced with a wooden skewer or a sharp pin. Hypothesis: If we lubricate the skewer with petroleum jelly‚ then it should go through the balloon without popping. Hypothesis for the 2nd part of the Lab: If we cover the side of the balloon with cellophane tape‚ then it will not pop when pierced with the pin. Materials: • Balloons • Long wooden

Isolation‚ Expression and Cloning of Lactate Dehydrogenase Gene from Lactobacillus bulgaricus Lactobacillus bulgaricus is used for industrial production of yogurt mainly because of his fermentative capability. In this experiment‚ the gene encoding the enzyme lactate dehydrogenase [ldhA] from the bactaria was isolated and cloned. The expressed ldhA gene was inserted into pET28b plasmid vector. The resulting recombinant pET28b-LdhA expression vector was then transformed after introduction into E.

High School Students – Prepared or not Prepared A big question today is‚ “Are high school students prepared for college?” The answer to that question is seemingly unknown. Research‚ from McMahon and Myers‚ has shown high school students are not being properly prepared to enter college straight out of high school. This makes it my goal as a future teacher that all of my students will be properly prepared for college‚ when they have finished my class. When unprepared high school students enter college

By doing some research I have been able to find out what it was like for the people of New Orleans when it was hit by a strong hurricane‚ called Katrina. The hurricane lasted 7 days‚ in between the dates of the 23rd of august and the 30th of august‚ 2005. There were an estimated value of 1833 causalities between those dates and wind pressures managed to hit up to 280 km/h‚ making it a category five hurricane‚ the highest you can go. The official city‚ state and the federal plan was basically

MATERIAL AND METHODS Stability of cell membrane using pH For the lab experiment for testing the stability of beet cell membranes using pH‚ many materials were used as follows. Obtaining a beet we punch out cores‚ using a cork borer. After washing the cores we put each one inside a separate test tube‚ and added a different pH solution in each one. After 3 minutes in these exposure solutions‚ we took the beet out with a dissecting needle. Then transferred each beet to a separate test tube containing
