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

However‚ they soon learned that horses would destroy cornfields and consume large amounts of the dwindling supply of cottonwood bark. Within the Eastern Plains there were many different

Transport System of Organisms Problems faced by Multicellular Organisms: a)Big size-the total surface area to volume (TSA/V) is decreased . Rate of diffusion of substances into and out of all body cells is low. b)Cells are often located far away from the external surface of the body. How multicellular organism overcome these problem? a)Have specialized structure to increase the surface area for the exchange of respiration gases. b)Have transport system to get gases respiration in and
