is to keep retail prices low. Working with suppliers to ensure their prices are constantly low‚ but also means price changes are kept to a minimum. 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 market. Competitive advantage is achieved by driving down costs. Price Leadership – The Company is well known for its “Every Day Low

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

Goh Biology SAC 3 “The Transport systems play an essential role in the survival of flowering plants and mammals” It is imperative that the organism’s cells have an ideal supply of the necessary materials to ensure its survival. At the same time‚ waste material must be removed to make room for the new material coming in and to avoid infection. Necessary substances and waste material merely move in and out of unicellular organisms by diffusion‚ osmosis or active transport due to direct contact with

When faced with taking private cars or publictransport people react in different ways. I will discuss for and againstarguments about using either private cars or public transport in this essay. Some peopleprefer use private cars to public transport for several reasons. First‚ theythink that private cars are faster than public transport since you don’t haveto spend your priceless time waiting for the bus under a bus-shelter crammedwith people. Second‚ you can go from work to home directly without stoppingtime

be made to encourage people to use their cars less and public transport more. Discuss possible ways to encourage the use of public transport. You should write at least 250 words. In a world of increasing environmental awareness improved public transport represents the way of the future. Although people do enjoy the convenience and privacy of traveling in their own private vehicles‚ in my opinion they may choose public transport if it fulfills certain conditions. These conditions fall into three

TRANSPORT IN MAMMALS Blood is a connective tissue and every connective tissue consists of cell‚ ground substance or matrix and fibres. For blood‚ it has cells‚ matrix in the form of plasma and fibres in the form of fibrin. In transportation‚ the surface area to the volume ratio of organisms contributes to the rate of movement of materials. For example in Hydra‚ and flat worms‚ the ratio is so high so simple diffusion can allow substances to reach all tissues easily. If the ratio is low‚ in mechanisms
