Gerald McDonnell 1. The major differences between prokaryotes and eukaryotes are as follows; prokaryotes are much smaller than eukaryotes, prokaryotes have a nucleoid instead of a nucleus (which eukaryotic cells have), prokaryotes lack a membrane bound organelles while eukaryotes have them, prokaryotes are bacterial cells while eukaryotes can be considered the building blocks of plant and animal life. 2. A. A nucleus is basically the “brain” of a cell. It controls reproduction and contains the genetic

Aseptic packaging or processing is where a food product, such as ultra-high temperature (UHT) milk) and its package is sterilized separately and then combined and sealed under sterilized atmosphere. The first practice of this was in Denmark in 1913 packing milk in metal cans. In 1921 a patent was granted for the process under the term aseptic conservation. In 1923 aseptically packaged milk from South Africa was shipped to London to a trade fair and it arrived in perfect condition. In 1933 a filling

1. Introduction: Chitosan is a natural biodegradable polymer composed of 2-amino-2-deoxy-β-D-glucose (D-glucosamine) with β (1-4) linkage, and with occasional N-acetyl glucosamine residues (Austin et al., 1981). This is a biopolymer that is consistently playing an important role in the world’s economy since it is biocompatible, biodegradable, edible, and antimicrobial (Muzzarelli & Muzzarelli, 2005). As compared with other bio-based food packaging materials, chitosan has antibacterial activity by

Gmo’s have been used to modify our food so that they can resist pests and temperature changes, along with other various inhabitants. They have become a controversy with the unconventional practice of splicing animal and insect genes into our food in order to give it traits that not only help with yield but weather changes and lack of soil integrity. With the technological advances in saving and improving the food we need to eat, I think we need to take advantage of what is available to us and find

lungs. Colonization of bacteria in the lungs can be caused by the spread of organisms from many different places, including the ventilator circuit. Breathing in those bacteria from any source, especially the circuit can cause an active host response. An endotracheal tube also provides an area for colonized bacteria to enter and infect the patient. On the other hand, aspiration of things like gastric acids can be harmful, because the stomach acts as a reservoir for different bacteria. A nasogastric or

Infection Control Guide Ryland Gallagher Illinois State University, Summer 2016 2 Infection Control Guide When implementing infection control, it is necessary to have an adequate background of how infection is transmitted. Furthermore, it is critical for an audiologist to identify key clinical situations in which infection is likely, warranting the need of appropriate preventative measures. Information and procedures pertaining to many of the components of infection

Inflammatory bowel disease (IBD) is an inflammation of the digestive tract persisting for a long period of time. A typed of IBD would include chrons disease. 700,000 Americans are currently diagnosed with this disease. Chrons disease can affect different parts of the digestive tract and will likely advance far into the bowel tissue layers. To what causes chrons disease still remains a mystery. Scientist believe a person’s heredity and immune system are a factor in what causes this disease. If ones
