Clostridium Perfringens Clostridium perfringens (formerly known as C. welchii‚ or Bacillus welchii) is a Gram-positive‚ rod- shaped‚ anaerobic‚ spore-forming bacterium of the genus Clostridium. C. perfringens is ever present in nature and can be found as a normal component of decaying vegetation‚ marine sediment‚ the intestinal tract of humans and other vertebrates‚ insects‚ and soil. Infections due to C. perfringens show evidence of tissue necrosis‚ bacteremia‚ emphysematous cholecystitis

All living cells have plasma membranes; this membrane regulates the interchange of materials between the cell and its environment. The main areas of its structure are a bilayer of phospholipids‚ and proteins. The phospholipids are responsible for the isolation

Biology Project Autumn Brown 3rd block Mrs. Stephens More than 2‚000 years ago‚ Aristotle began grouping plants and animals into various categories. Although he did not consider the idea that different organisms were related by descent‚ he devised a system that placed these organisms in a hierarchy. Through classification systems‚ scientist have found it easier to find answers to important questions. This way

Associate Program Material Prokaryotic and Eukaryotic Cells Worksheet Provide a list describing at least three differences between prokaryotic and eukaryotic cells: 1. Number of cells – prokaryotic cells is single celled while eukaryotic cells can be single or multi celled. 2. The size of the cells – prokaryotic cells are really extremely tiny while eukaryotic cells are just extremely tiny. 3. The DNA structure – prokaryotic cells are a single circular chromosome attached to the

NAME: Andrade Sanjines Paola Andrea THE FIVE KINGDOMS In the world there is a great variety of living creatures and each belongs to a kingdom. The five major kingdoms are: the kingdom monera‚ the kingdom protista‚ the kingdom fungi‚ the kingdom of the plants‚ and the kingdom of the animals. The kingdom monera contains primitive organisms. These organisms are very small‚ single celled and do not have a nucleus. They consist of prokaryotes which include species like the bacteria‚ archae bacteria

Kofoed Biology 1407 Horizontal Gene Transfer Responsible for Carotenoid Production in Aphids Horizontal Gene Transfer Horizontal gene transfer (referred to as HGT for the rest of the paper) is said to have occurred when an organism successfully incorporates genetic information from another organism into its own genetic makeup when the first organism is not the offspring of the other organism. HGT‚ or lateral gene transfer (LGT)‚ is used to describe both the artificial and natural
