Petri Dishes Test Tubes
899 wordsControlled Comparison: During class, our instructor set up the same lab that we were doing with 2 solutions, both of which were known acidic or basic. He placed 2 ml of the known acid into 2 different test tubes, and 2 ml of the known acid into 2 different petri dishes. Then using forceps, he tested blue litmus paper in one petri dish, and red litmus paper in another. The blue litmus paper, after being dipped into the solution, turned red in reaction to the acidic solution. While the red litmus ...

Petri Dishes Bacteria Cells
1,566 wordsIn this lab we observed the growth of bacteria in a conjugation and transformation experiment. We expected the mating plate of the conjunction to grow and the bacteria on the transformation plates to grow also. We also practiced using aseptic techniques to clean the lab benches and to keep the bacteria from being contaminated from outside bacteria. This lab will take a total of 2 days because of the observations that need to be made. The parts of this paper will explain the procedure and the obs...

Dry Ice Petri Dishes
1,905 wordsA particle cloud chamber is a device that makes visible to the human eye the presence of certain particles and cosmic rays. This paper will discuss the process in which a successful chamber prototype was developed. This paper will also discuss how the chamber utilizes the properties of a supersaturated environment to detect these particles. Finally, plans for the future development of a larger model to study the charge and energy of particles through the use of a magnetic field is presented. The...

Gram Negative Petri Dishes
1,384 wordsAbstract/Summary: Changing our focus from the properties and functions that take place within the cell to the actual cell itself, we observed three specific bacterial types within this lab: Gram-positive bacteria, Gram-negative bacteria, and cyanobacteria. We closely observed the features of cyanobacteria and were able to differentiate them from other bacteria. We specifically observed gloeocapsa, merismopedia, anabaena, and oscillator. In addition to this we observed the different characteristi...

No significant difference in insulin concentration was observed when incubation's were carried out at 5. 5 -mmol / l medium glucose concentration (15816 gU/ml, gU/ml, n = 6) or at a 25 -mmol / l ambient medium glucose concentration (146. 2 bn 22. 1 gU/ml, n = 6). (Assay et. al. , 2001) Method 2: As a result of their ability to differentiate into many different cell types, one can dissect the complex network of transcription factor genes regulating tissue-specifi...

3,855 wordsIs there an effect on Rhizobium bacteria by changing its pH? Steve Lincoln Period 3 12 / 7 / 98 Question What are the effects of varying pH levels on Rhizobium bacteria, and can a pH resistant Rhizobium culture be grown? Hypothesis Alterations of the balanced habitat such as the change of pH levels can drastically alter the life of bacteria and can directly affect chemical reactions of enzymes released by the bacteria. Using this information the change in pH will have an effect on the Rhizobium ...
