Diffusion‚ Osmosis and Active Transport Substances will move through the membrane by diffusion. This is the random spreading out of particles until they are even. For example‚ when you put your instant coffee in boiling water‚ the coffee particles spread out and fill the entire mug‚ this is diffusion. A second way that substances can move through the cell membrane is by osmosis. This is a special type of diffusion where water moves from a high to a low concentration through a ’partially permeable

BACKGROUND OF THE STUDY It has been widely viewed‚ documented and believed that South African transport policy and transport plans focus almost entirely on passenger transport rather than on freight transport‚ yet Freight transport plays a very crucial role in the whole transport pricing‚ and the economy as a whole.

landlocked. Nevertheless‚ the lack of unhindered access to the sea adds transport costs and time to international trade transactions. In addition‚ landlocked countries face greater transport risks and hazards than countries which have direct access to international sea routes. The United Nations has addressed the specific concerns of landlocked countries in a number of documents. Among those which are directly related to transport are the following: General Assembly resolution 50/97 of 20 December

Lipids and Phospholipids The main role of phospholipids is that they can form lipid bilayers. It is an amphipathic molecule. The head which is hydrophilic contains a group of phosphate‚ a diglyceride and a simple molecule e.g. choline. The tail is hydrophobic and is made up of fatty acids. Phospholipids receive and transmit signals across the cell membrane and act as a store room for energy. The main role of phospholipids is that they can form lipid bilayers. It is an amphipathic molecule. The
