Advanced Food hygiene Assigment question 6 Non Bacterial Food Posioning Food poisoning can be caused by the consumption of food contaminated by substances other than bacteria. This can occur by contamination of the food by chemicals‚ the ingestion of poisonous plants and by eating fish or shellfish that have been feeding on poisonous plankton or living in contaminated waters. Several foods contain naturally occurring poisons. This is more common in plants; there are hardly any animals that are

Formal lab report: Abstarct: The Purpose of this experiment was to perform Agrobacterium-mediated transformation in Wild type Arabidopsis thaliana Columbia by using somatic plant transformation method. The whole process lasted for over a period of 11 weeks and we were successful in getting transformed plants. Agrobacterium tumefaciens strain containing pMP90 (Ti-helper) plasmid and pCAMBIA1391 (T-DNA) plasmid was used for this plant transformation. pCAMBIA1391 plasmid was constructed by cloning Brassica

Urban Gentrification and Urban Morphology The term ‘gentrification’ has myriads of interpretations from different geographers‚ and sociologists. Ever since‚ there has been protracted debate on its methodology‚ consequences and whether it constitutes a dominant or residual urban form. The term ‘gentrification’ was first coined by the Marxist urban geographer Ruth Glass (Glass‚ 1964) to describe the influx of wealthier individuals into cities or neighbourhoods who replace working or lower-classes

Bacterial Energetics and Membranes Abstract The Mg2+/Ca2+ ATP synthase present in all bacterial membranes‚ particularly E. coli‚ couples ATP synthesis to the proton (H+) gradient produced by the ETC‚ a process known as oxidative phosphorylation. The gradient acts to power the ATPase‚ so that it may phosphorylate ADP to produce ATP. The reverse reaction of this process‚ or hydrolysis of ATP into ADP and Pi‚ may be used to observe ATPase activity when the resulting Pi is quantitatively measured

Transformation is a process which involves plasmid DNA being bound to the cell surface and the subsequent uptake of DNA by the cell (Panja et al.‚ 2008). For artificial transformation of E. coli cells with plasmids‚ plasmid DNA has to be extracted from bacterial cells using the High-Speed Plasmid Mini Kit‚ which is then mixed with competent E. coli cells followed by heat shock and the streaking of transformed cells on two different types of agar plate (LB and LB+ampicillin). The extracted plasmid DNA is

Studying primate dentition is a relatively old topic. There have been many studies conducted to find more information on primate dental morphology. The research is conducted to try and distinguish the relationship between diet and primate dentition. Primate teeth have several functions‚ but their primary function is the mastication of food. Their dental morphology reflects the various functions demanded by the variety of food types—shearing‚ chopping‚ grinding. Generally‚ incisors function chiefly

At the beginning of the semester‚ samples of bacteria were obtained from various sources. Two bacterial colonies were isolated from plates that were incubated in the lab and these bacteria became the basis for this project. The bacterial cultures were maintained and used for various physiological‚ cultural‚ and biochemical tests and observations over several weeks. The purpose of culturing bacteria over half the course of the semester was to learn various techniques used in microbiology labs and

The Mandarin Chinese language (and all other dialects of Chinese including Cantonese) lacks any kind of overt inflectional morphology. In Chinese‚ words are typically formed by one or two written characters. Each character is monosyllabic and can usually stand alone as an unbound morpheme‚ making inflectional changes more or less impossible. As a result‚ the Chinese language family has no method of overtly expressing tense‚ number‚ gender‚ etc. Instead of inflectional changes‚ Chinese uses context

Introduction: Settlement morphology is primarily concerned with the lay-out‚ plan and internal structure of the settlements. It not only views settled area in terms of physical space but identifies its various components in respect of socio-economic space which has its direct bearing in controlling the arrangement of buildings‚ patterns of streets and fields and functional characteristics of settlements in general. Types‚ Form and Pattern constitute the three basic elements of morphology of rural settlements
