Cellulitis is a bacterial infection that affects the skin and the tissue underneath the skin. Although cellulitis can be caused by many types of bacteria‚ streptococcus and staphylococcus are the main bacteria that cause this condition. Cellulitis often develops near surgical wounds or ulcers. This condition causes the skin to become reddened and swollen. It also causes the area to feel tender and hot. Cellulitis can quickly spread to other areas of the body. It is not contagious. Cellulitis can

Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

Abstract The primary focus of this lab was on microscopy and simple stains. Crystal violet and Carbol fuchsine‚ simple staining components‚ were used to stain the slide in order to see the different microbes in order to determine their cellular shape and identify unknown ones by comparing. Introduction Bacterial cells are usually colorless because cytoplasm‚ for the most part‚ is transparent. Since the bacteria are colorless‚ it is almost essential to add a stain to make the bacteria more visible

Leaves are the most significant photosynthetic tissue for the majority plants and play a crucial role in response to biotic and abiotic disturbances. Leaf shape is seen as one of the most variable and distinct plant traits‚ and variation of leaf morphology can exist among species‚ populations and individuals‚ and within individuals. Because leaves are critical to plant growth and survival‚ it is assumed that the variation in leaf shape represents an adaptive consequence caused by natural selection

Describing the appearance of bacterial colonies has been an important tool for microbiologists. On solid media‚ a colony is theoretically derived from a single cell. If well separated from other colonies‚ a colony will have a characteristic shape (both in elevation and margin)‚ size‚ color‚ and consistency. Usually‚ observation is made with the naked eye‚ but dissecting microscopes are also used. The characteristics defined by a colony’s morphology may be used at a superficial level to distinguish

Necrotizing Fasciitis is a bacterial skin infection that is caused by one or more bacteria that enters one’s skin through a cut or wound. It can be fatal if not treated in time. Necrotizing Fasciitis is commonly known as the ‘flesh eating infection’ that occurs suddenly and spreads extremely fast. It corrodes the skin and the tissue beneath it. It can be caused by one or more bacteria‚ for example Streptococcus pyogenes‚ Kebsiella‚ Bacteroides and more. Approximately 700 hundred cases are recorded

The convergence in external morphology of sharks‚ penguins‚ and porpoises is attributed to selection pressures that are common to these groups Genes that are located on the same chromosome are all of these An incompletely dominant gene controls the color of chickens so that BB produces black‚ Bb produces a slate-gray color called blue‚ and bb produces splashed white. A second gene controls comb shape‚ with the dominant gene R producing a rose comb and r producing a single comb. If a pure-breeding

gain knowledge on how to use a microscope and oil immersion lens while observing prepared bacterial slides and also to prepare slides for observable bacteria culture from yogart. Procedure: Exercise 1: Using the Microscope - Viewing Prepared Slides I started out by reading and reviewed the science lab safety reinforcement Agreement and the instruction to oil immersion lens. After setting up my lab station I view the six prepared slides with 10x and 40x objctives lens. In each slide the
