Network Design: Logical and Physical Design In networking terminology‚ the term network topology refers to the entire structure of the network. There are two primary parts to the topology definition: the physical design‚ which is the actual layout of the wire (media)‚ and the logical design‚ which defines how the media is accessed by the hosts. The physical designs that are commonly used in networks are the Bus‚ Ring‚ Star‚ Extended Star‚ Hierarchical‚ and Mesh. A bus topology uses a single

fundamentals of science. Title An investigation of an onion cell using a light microscope. Aim: The aim of this investigation is to identify the cells within an onion skin using a light microscope. An onion cell is a plant cell which through the light microscope‚ it should outline the cell wall‚ cell membrane and the nucleus. Introduction: Plant cells have a cell wall and cell membrane which animal cells do not have. The cell wall provides support and is relatively rigid‚ which consists of

Lab #5: Refraction of Light Theory: Refraction can be defined as the bending of a wave when it enters a medium which causes it to have some reduced speed. In terms of light‚ refraction occurs when the ray passes through some medium which slows its speed; such as water or glass. In this instance the ray tends to bend towards the normal of the medium. The amount of bending or refraction which occurs can be calculated using Snell’s Law (). Objective: To measure the index of refraction of Lucite

The effect of temperature on beet cell membranes Introduction: A cell membrane of a beet (Beta Vulgaris) is made up of a phospholipid bilayer with embedded proteins and cholesterols. The membrane is responsible for organizing the cell‚ protecting it from the exterior environment‚ as well as responsible for regulating what goes in and out of the cell though it’s protein channels and “selectively permeable” bilayer. (Campbell‚ Reece‚ Taylor & Simon‚ 2006‚ p. 79-80) When this membrane is damaged

sure to answer the following reflection questions in the conclusion of your lab report: 1. How much did the egg change in size? (answer should be in centimeter) The egg’s size changed by 3 centimeters. 2. Was your hypothesis correct? Why or why not? My hypothesis proved to be correct because the egg’s shell did‚ in fact‚ deteriorate. 3. Evaluate the lab and data collected. What type of transport occurred in this lab? Explain your answer‚ including evidence from your experiment to support

Recent studies of stem cells have played are very important because they show promise in helping man solve or at least grasp the solution to the diseases that have haunted him since his early days of conscious. The idea of stem cells is kind of a simple idea. This brings us to the first promise‚ not only are stem cells able to be taken from the human body‚ but scientists are now able to grow these cells in labs. The most worried over part is that when obtaining the cells‚ it doesn’t always
