Are viruses alive? Explain why you think viruses are alive or not. Viruses are not alive. This is because even though viruses are made up of molecules (proteins‚ nucleic acids‚ carbohydrates and lipids)‚ they cannot do anything on their own‚ until they enter or come into contact with a living cell. Viruses cannot multiply without having a host cell to initiate the process. Another reason would be that viruses don’t actually do anything on their own. Whenever a virus comes into contact with a cell

and diagnose conditions. Fortunately‚ there are research findings available that indicate the effects of hypoxia on a cellular level including the effects of hypoxia on the intracellular ion balance (McCance & Huether‚ 2013). This document provides an explanation of how hypoxia can change the intracellular ion balance. Understanding the Basics Hypoxia is described as having an inadequate amount of available oxygen (McCance & Huether‚ 2013). Cellular responses are often a like a chain-linked reaction

Component Diagram Notations The component diagram’s main purpose is to show the structural relationships between the components of a system. In addition‚ component diagrams are useful communication tools for various groups. In creating a component diagram‚ there are different notations that can be used to show the different relationship of each component within the system. The component diagram notation set now makes it one of the easiest UML diagrams to draw: * COMPONENT A component can

#1. Entity Relationship Diagram #2. a. & b. One Room can be designated only one Room Type‚ whilst a particular Room Type can be assigned to several rooms (i.e. there may be many rooms that have double beds). Therefore‚ Room has a one-to-one relationship with RoomType and RoomType has a one-to-many relationship with Room. From the table‚ it can be seen that a particular room can only be designated as belonging to one type / category‚ thus confirming that Room RoomType has

POTENTIAL ENERGY DIAGRAM In physics the terms of mechanical energy usually refers to Potential energy (U) and Kinetic Energy (K). In the absence of non-conservative‚ or dissipative forces‚ these energies obey the law of conservation of energy‚ or ΔU + ΔK = 0. That is‚ when a system is only acting under the influence of conservative forces its total energy content never changes‚ the energy just converts between forms. At any point in the cycle‚ the total energy is constant‚ U + K = Umax = Kmax

DATA FLOW DIAGRAM Group#7 Nugao Oserin Obongen The Data Flow Diagram (DFD) • a graphical representation of the flow of data through an information system. It enables you to represent the processes in your information system from the viewpoint of data. The DFD lets you visualize how the system operates‚ what the system accomplishes and how it will be implemented‚ when it is refined with further specification. • Data flow diagrams are used by systems analysts to design information-processing systems
