Baby food can be purchased for less than a dollar at a grocery store. It makes a great test subject; however‚ make sure you use the same sized jar and food type when conducting multiple experiments. Test bacteria on any surface with the Surface Microbes Science Fair Projects Kit: after hand sanitizer‚ hands‚ disinfectant for example. You can use antibiotics to test the bacteria too. Anytime you want to test how many bacteria are On Top of a surface like a desk‚ skin‚ chicken‚ computer keyboard

seed germination rate‚ as well as a shorter radicle length. Procedure 1. Label petri dishes with the appropriate concentration levels and place filter paper in each dish. 2. Treat each dish with 2mL of the appropriate concentration of the bleach solution 3. Place 6 seeds in each dish. Make sure they do not touch the sides of the dish or each other. 4. Leave the dish in a dark place so that the roots can grow. 5. Dishes were left in the dark for four days due to the blizzard

into a sphere shape called a blastocyst (day 1-5). These embryonic stem cells are now visible and can be developed into any of the bodies 200+ tissue cells (day 5-7). After this stage the embryonic stem cells are removed and grown in a separate Petri dish. As they continue to divide‚ they create a line of stem cells. In future scientists hope to turn these stem cells‚ perfectly matched to the patient‚ into tissues. There are many benefits that can come from therapeutic cloning. By taking healthy

the techniques unfortunately some of the points were not successful. This could have been due to me and partner not carrying the whole experiment in a sterile environment e.g. near the Bunsen burner or it could have been to due exposing the whole petri dish when we are spreading on the bacteria on the agar plate other bacteria that was around could have caught on. Streptomycin is an antibiotic used to kill sensitive bacteria. It is an aminoglycoside which works by stopping the production of essential

Proteus vulgaris Antibiotic Sensitivity Assay By: David Toelkes BIO 225 June 12‚ 2012 Lab Partners Alexis Blackmon Cheryl Cardiff Megan Dereani Logan Freeman Abstract Development of bacterial resistance to the antimicrobial drugs identified the need to determine a given bacterium’s susceptibility or resistance to a given drug which prompted W. M. M. Kirby and A. W. Bauer to develop a single disk method for susceptibility testing. This experiment used the Kirby-Bauer disk diffusion

Armadillium vulgare taxis response to different pH levels. Abstract The terrestrial isopod‚ Armadillium vulgare is commonly referred to as a slater or pill bug. Since transitioning from the sea to land and originally colonizing in Mediterranean regions‚ it has adapted throughout evolution to inhabit local microhabitats. The pill bug is bound by several parameters and also has specific requirements that need to be met for optimal biological functioning. As such‚ behavioural and physiological

which antibiotic would be effective for treatment. Doctors often diagnose MRSA by checking a tissue sample or nasal secretions for signs of drug-resistant bacteria. Current diagnostic procedures involve sending a sample to a lab where it is placed in a dish of nutrients that encourage bacterial growth (a culture). It takes about 48 hours for the bacteria to grow. However‚ newer tests that can detect staph DNA in a matter of hours are now becoming more widely available. This will help healthcare providers
