double dipping and the bacteria that comes from it. What they are trying to discover is, Does double-dip practice pose and concerns? With a specific question of how many bacteria are transferred from the perpetrator's mouth to dip?

Proving that if you do take a bite out of the cracker and double dip, you will transfer more bacteria. In Experiment 2 they

technique was gram staining. This technique was used to determine if bacteria is present. Then, it had to be determined if the organism was gram positive or gram negative. During the staining procedure there is a primary stain of crystal violet, the mordant gram iodine, a decolorizer acetone alcohol, and a counterstain of safranin. After the steps are completed the gram positive organism remains purple and the gram negative bacteria shows as a reddish-pinkish organism. Gram staining came about by Hans

Gmos stands for genetically modified organism; they are living organisms whose genetic material has been artificially manipulated in a laboratory through genetic engineering. Gmo’s are not considering being safe. Although no one has been harmed by eating gmo foods , some still think that it is bad for your health. The vast majority of corn, canola, and sugar beets grown in the u.s are now genetically engineered, and they are often used as ingredients in processed foods. The food industry is also

The Biology and Pathology of cystic fibrosis Cystic fibrosis is an inherited condition which occurs when the gene that prevents the lungs and digestive system being clogged with mucus is faulty. This is due to a chloride channel being unable to function as it should and open when there is an increase in the level of cyclic AMP. This could be due to an associated regulatory protein being unable to undergo phosphorylation. It affects the function of the exocrine glands in a person’s respiratory and

Germs are evolving faster than medicine can keep up trying to cure it. A polymer spray has created to stop bacteria from communicating; therefore, people will be sick less. Because animals food has antibiotics in it, humans has been over exposed. In general, antibiotic resistance have been causing people to be ill more. One cause of overexposure to medicine the effects of germs a bacteria have to resist antibiotic medicine. According to “Doctors enlisted” it won't be easy to ending antibiotic

theory, involved filtering air to gather its contents. He filtered the air using cotton, which he later used alcohol to collect the particles, which had been filtered. He later analyzed the extract and found microbes, which looked similar to other bacteria. This raised the question that if these types of microorganisms would be found in the air then, they could access any material and result in contamination (Cappuccino & Sherman, 2008). Louis further conducted a second experiment where he used a
