Should Bacteria and Archaea belong to the same Kingdom? The main purpose of this essay is to find out if Archaea and Bacteria should be classified as two different Kingdoms or as a single one. As organisms‚ bacteria and archaea both are microscopic and prokaryotic (not possessing a true nucleus). These prokaryotes are very abundant on Earth and inhabit a wide spread of areas‚ including extreme ones. Both are an example of the most ancient living cells‚ which have appeared over 3.5 billion years

neurogenic changes. Many myofibers with multiple clusters of blue red rod-like structures and cytoplasmic inclusions were noted. Immunohistochemistry showed a focal positive reaction in sarcoplasm to desmin and myotilin antibodies. An electron microscope study revealed variable abnormalities of myofibrillar structures. To the best of our knowledge‚ this is the first reported case of MFM with pathology findings in Korea. Key Words : Myofibrillar myopathies; Desmin; Pathology CASE REPORT

infection that must utilize the cellular machinery of bacteria‚ plants or animals in order to reproduce. Composed of a single strand of genetic material (DNA or RNA) encased in a protein capsid‚ a virus is too small to be seen by standard light microscopy; indeed‚ most are less than one hundredth the size of a bacterium. Specific proteins on the viral capsid attach to receptors on the host cell; this attachment process is essential to viral infectivity and explains why viruses may only infect

HUMAN PHYSIOLOGY REPORT DAPHNIA Aim The aim of this experiment is to investigate the effect of temperature and various substances on the heart beat of Daphnia‚ a water flea. Introduction Daphnia belongs to a group of small‚ freshwater crustaceans of the order Cladocera commonly called water fleas. They are very suitable for laboratory studies due to the nature of their transparent exoskeletons. Hence‚ it is possible to watch Daphnia hearts without dissecting them. Daphnia is ectothermic and

Investigation of the effect of particle size distribution on the flow properties of bulk solids Abstract This paper reports from a Defra sponsored project which aims to develop a toolkit that can be used by formulators to assist in controlling the flow properties of blended or engineered powders. This paper presents the results of an investigation into the effect of the breadth of the particle size distribution on the flow function‚ bulk density and internal friction of four food grade fillers

Running Head: APPROACH TO CARE Approach to Care of Cancer NRS 410V David Ludwig 1/16/2011 Grand Canyon University Introduction According to the American Cancer Society‚ half of all men and one third of all women will develop cancer within their lifetime (Cancer.org). These figures are staggering. Cancer is a leading cause of morbidity and mortality worldwide and is a terrifying and unpredictable disease for many cancer sufferers. As such‚ it is imperative that healthcare workers have

Fetal risks are highest in women with early syphilis. In the initial disease a presumed diagnosis of syphilis can be made upon observation of the patient and sexual history. Dark field microscopy of exudate from the lesion is a reliable way to confirm the presence of spirochetes. Light through the microscope fitted with special lenses allows the visualization and identification of the corkscrew morphology of the spirochete as white against a dark

Introduction The purpose of this project was to detect which organism we had in our unknown mixed culture tube by running a series of experiments to detect which specific Gram negative organism we had. To detect your gram positive from the mixed culture was given as extra credit points also. A Gram stain was performed and isolation streak plate in order to isolate and observe the unknown organism. Before the series of test‚ a dichotomous key had to be written up in order to know what steps
