to talk of the period after the Second World War as one of enormous upheaval in which the traditional patterns of life in Britain were swept aside to be replaced by a new‚ and superficially less class-ridden system. Sociologists have dwelt in particular upon the disintegration of the working-class community and have demonstrated how the demolition of the traditional environment of back-to-backs and corner shops merely signified deeper and more intangible changes. None the less‚ despite the confident

The digestive system is very important to the body. Without it‚ we would not be able to live. It is a series of hollow organs joined in a long‚ twisting tube from the mouth to the anus. The tubes actually are about 30 feet long if they were stretched out‚ but seem smaller because of the way they are wrapped around. The main parts are the mouth‚ teeth‚ esophagus‚ stomach‚ small intestines‚ large intestines‚ colon‚ rectum‚ and anus. The pancreas‚ gallbladder‚ and liver are also key parts because of

Male System The structure and function of the human male reproductive system‚ is very similar to that of many other mammals. The male system is designed to make sperm or male gametes and is adapted to provide for the delivery of these gametes to the female to allow for fertilization. Male Reproductive System Male Reproductive System Structures 1. testes -- produces sperm and the hormone testosterone 2. scrotum -- pouch enclosing the testes keeping the sperm at an optimum temperature

oil (lipophilic). This means that they will coat the surface of oil droplets in an oil-in-water emulsion and effectively ’insulate’ the oil droplets from the water. It keeps them evenly dispersed throughout the emulsion and stops them from clumping together to form their own‚ separate layer. In a water-in-oil emulsion‚ the emulsifier coats the water droplets to stop them from separating from the oil. This property makes emulsifiers indispensable in the modern food industry where foams‚ suspensions

The working (lower class) in Australia mainly lived closer to the city‚ squashed together in the slums. Some examples are in Sydney – Pyrmont‚ Redfern and Surry Hills and in Melbourne – Collingwood‚ Richmond‚ Port Melbourne and Footscray. They lived at the bottom of hills where flooding enabled water borne diseases such as cholera and typhoid fever to breed spread throughout communities. Families of 10 were squeezed into inadequately sized‚ poorly insulated‚ iron houses where they struggled to pay
