The body of the earthworm is divided into several segments which carry bristles that are called setae. The entire body of an earthworm is surrounded by a thin mucus which increases its mobility. At the first segment of the body, the…

In the article “Spectacles of Death: Identification, Reflexivity, and Contemporary Horror,” Jeffrey Sconce compares two wildly different films (“Henry: Portrait of a Serial Killer” and “Freddy’s Dead”) as a way to explain how self-reflexivity and identification make the films all the more appealing to its demographic audience. In all films, the “enunciator” crafts a window of “psychological reality” where the spectator identifies with the visual field as a bona fide reality through the use of…

formation and remodeling of tissues by extracellular matrix degrading functions. Gelatinase has broad spectrum of the substrate which hydrolyses various substrates namely gelatin, fibrin, collagen, fibrinogen, casein, Hemoglobin, Insulin, some sex-pheromone related peptides and other bioactive peptides of the E.faecalis (Makinen et al., 1989). Being gelatinase is a potential role in virulence of E.faecalis its levels were increased in oral rinses, saliva samples and crevicular fluid (Makela et…

they located? They are sweat glands and they are located throughout the body. 11. What is sweat composed of and what are two functions of sweat?

BEE PRACTICAL FINAL ASSESSMENT Draw and describe the structures that may contribute to a drone’s mating success. When coming into contact with the queen, the drones’ hind legs attach to the queen’s abdomen from behind. The drone then inserts his endophallus into the queen’s abdomen which allows sperm from the male to flow into the queen, allowing insemination (Koeniger & Koeniger, 1991). The secretions from the drones cornua increases the attachment between drone and queen (Koeniger & Koeniger,…

There’s only one animal besides humans that can build a dam, the beaver. The beaver is a very exceptional mammal because it can create, modify, and control its habitat. Beavers typically inhabit the northern hemisphere, but have also been introduced in South America’s Tierra del Fuego (Cavendish). Beavers are the second largest rodents in the world and have many similar relatives such as the nutria (Cavendish). The main characteristic of a beaver’s habitat is its dam. A dam allows the beaver to…

The greenhouse effect is a naturally occurring process within our atmosphere, it aids in heating the earths surface and atmosphere. The greenhouse affect is caused by the fact that certain atmospheric gases, gases such as carbon dioxide, water vapour and methane are able to change the energy balance of the planet by absorbing long wave radiation emitted from earth’s surface. Without the greenhouse affect our earth would be a chilly -18°C in comparison to the present average temperature of 15°C.…
