Modern methods of transport have transformed our world into a village. Is this a blessing or a curse? In some respects the topic-statement is true. Modern transport‚ especially by air‚ allows people to circle the globe in a few days‚ or hours‚ if an aircraft such as Concorde is used. Thus we have learnt to look upon distance as nothing. I can get to Paris from south-east England quicker than I can get to central London. So‚ the world has become a village? If so‚ the comparison ends there

Activity 1: Stimulating Dialysis (Simple Diffusion) 1. Describe two variables that affect the rate of diffusion. The two variables that affect the rate of diffusion are: • The composition of the lipid layer‚ this content varies from tissue to tissue. For example kidney tissues have a high cholesterol content which makes them impermeable to water. • The size of the molecule‚ the larger the molecule the slower the rate of diffusion. 2. Why do you think the urea was not able to diffuse

Transport in Plants Matthew H. 9A 131002 Today I will be discussing our experiment and the basics of transport of minerals and water in plants. Transport in plants are called transpiration. Water evaporates from the leaves which cause a type of suction that draws water from the roots. The water travels up via the vascular bundles. This flow of water is called transpiration stream. Some pressure is created forcing some water out of the cells in into the spaces between the cells

Water Transport The movement of plants from water to land has necessitated the development of internal mechanisms to supply all the parts of the plant with water. As discussed in Plant Classification‚ Vasular Tissues ‚ tracheophytes (including virtually all terrestrial plants except for mosses and liverworts)‚ have developed complex vascular systems that move nutrients and water throughout the plant body through "tubes" of conductive cells. The vascular tissues of these plants are called xylem

Aiming to become lowest cost producer‚ the firm can compete on the price with every other industries and earn higher unit profits. Cost reduction provides the focus of the organization strategy. It targets a broad

THE THREAT OF GLOBAL GRIDLOCK A Case Analysis GLOBAL BUSINESS MANAGEMENT September 25‚ 2012 EXECUTIVE SUMMARY The case “The Threat of Global Gridlock” by George Stalk highlights that the world is about to face a major crisis in transportation because of not meeting the demand of the global economy. The author believes that currently the threat has been masked away but it’s imminent and if the prerecession trend reappears it would be a serious problem with the lack of infrastructure and the

Public transport can be define as a system of vehicles such as buses and trains‚ which operate at regular times on fixed routes and are used by the public. In Malaysia‚ the number of vehicle on the road has been increase in every year. It shows that the public now is affordable to have at least a motorcycle as their daily transport rather than use the public transport. The public should not use the public transport because the risk of being the criminal victim will increase the people need to wait
