Active and passive transport are the ways in which cells allow things to move into and out of the cell through the cell membrane. They include many different ways to transport things. Passive transport requires no expenditure of energy by the cell. However‚ Active transport requires ATPs which have energy in order for it to move something through the cell membrane. There are different types of transport to suit the sizes of molecules as well. Passive transport includes diffusion‚ osmosis‚ and

SKIN DISEASES 1. Miliaria (also called "sweat rash" or "prickly heat") is a skin disease marked by small and itchy rashes. Miliaria is a common ailment in hot and humid conditions‚ such as in the tropics and during the summer season. Although it affects people of all ages‚ it is especially common in children and infants due to their underdeveloped sweat glands. 2. Measles is a highly contagious viral disease that can be very serious or even fatal. It begins with a fever that lasts for a

Gaseous exchange and transport Movement of chemicals in plants and animals -Chemicals that are being moved into the body‚ within the body or out of the body are gases‚ this movement is known as gaseous exchange. -The gases being moved in our out of the body need to move across the surface area of the body‚ in most cases a special surface area has been developed. -The surface that the gases cross is called the respiratory surface and the gases move across this surface by the process of diffusion

How Far did Changes to Transport 1750-1900 Benefit the British People? In this essay‚ I will be explaining how transport changes how they helped British People during the Industrial Revolution. I will be writing about three types of transport: Roads‚ Canals and Railways. At the beginning of the Industrial Revolution‚ in 1750‚ it was very difficult to travel on roads as there were a lot of holes that were full of water‚ which meant there was no drainage. This waster filled up all the ruts. All

4 OSI Transport Layer 4.1 Roles of transport Layer 4.1.1 Purpose The Transport layer provides for the segmentation of data and the control necessary to reassemble these pieces into the various communication streams. Its primary responsibilities to accomplish this are: Tracking the individual communication between applications on the source and destination hosts Segmenting data and managing each piece Reassembling the segments into streams of application data Identifying the different applications

is a Hotel‚ Restaurant‚ Leisure or Retail Feasibility Study A feasibility study is the key initial tool for assisting hotel‚ restaurant‚ leisure and retail development planning. Types of Feasibility Studies There are two main types of feasibility study – and many people confuse the two. Architects will undertake a development feasibility study to determine what is possible on a site. The results should not be confused with a market feasibility study that determines the financial viability of

Transport & Service costing Service Costing Unit costing is the method of costing used when the cost units are identical. Identical cost units should have identical costs and this concept of equality of costs is the basic feature of unit costing. It may be noted that process costs‚ output costing and service costing are the sub-divisions of unit costing method. Service Costing – Nature and Problem: Service or operating cost is the cost of providing services. Service costing
