Have you ever been diagnosed with meningitis or ever felt any symptoms and believed you had meningitis? Meningitis is an inflammation of the meninges caused by viral or bacterial infection. In this research paper the purpose is to explain why this disease is relevant in society today‚ the use of the disease as a biological weapon‚ the different types‚ the bacteria that causes meningitis‚ and the history of this infection. Through this research it will examine the role meningitis play in

H. sp. KHS3 is a moderately halophilic bacteria isolated from hydrocarbon-contaminated seawater of the Mar del Plata harbour (D’Ippólito et al.‚ 2011). In this work‚ we demonstrated that H. KHS3 can grow using different monoaromatic and polyaromatic compounds as the only carbon and energy source in a saline environment. Besides‚ we demonstrated for the first time the 4-HBA and BA degradation ability of H. sp. KHS3. Several Halomonas strains have been described as efficient aromatic compounds degraders

Study Guide 4 CH. 21 Genomics – the study of whole sets of genes and their interactions. Bioinformatics – is the application of computational methods to the storage and analysis of biological data Linkage Map – maps the location of several thousand genetic markers on each chromosome Physical Map – Expresses the distance between genetic markers‚ usually as the number of base pairs along the DNA Metagenomics – DNA from a group of species (a metagenome) is collected from an environmental

Our ecosystem relies on the basis of food chains. Food webs work through a series of food chains that link together. Invasive species are a part of our food web. Invasive species pose a great threat to the habitat of the existing native organisms. They can cause major disruptions to the existing habitats and so it is important to be able to stop their damage. Invasive species can be found in many different habitats including land and water. If the population of a given habitat increases‚ then there

orbit around the sun. All these are also part of the universe. It extends much farther than can be seen by the most powerful telescope. No one knows where the universe ends. 1 MODULE - 1 Environment through Ages Environmental Science Senior Secondary Course When you look up at the sky on a clear night‚ you see many points of light – most of which are stars. Stars are huge balls of bright‚ hot glowing gases. The ‘Sun’ is also a star. It is the star nearest to earth – about 150 mk (million kilometers)

the central nervous system which will relax the muscle and increase the gastric acid and heart rate (Kelly‚ 2017). The analyzing of caffeine and caffeine metabolites in saliva is to quantitatively measure the ratio of concentrations of caffeine and metabolites. There are three different metabolites of caffeine and the majority of caffeine metabolite is paraxanthine. The ratio of concentration represents the activity of the first metabolism enzyme of caffeine‚ CYP1A2 because it is responsible for the

extensively in plant genetic and metabolism studies. Specifically I was interested in the glucosinolate content in the plant. Glucosinolates are a group of plant thiogluciosides found in all members of the plant family Brassicaceae. This group of secondary metabolites is indicative of cellular differentiation and knowing their concentration within A. thaliana spatially and temporally would provide a wealth of information for how the plant controls and maintains cellular differentiation specifically in the
