Chapter 10 Review

Organisms that can’t make their own food consumed the food molecules made by autotrophs, eat autotrophs or eat organisms that consumed autotrophs. 2. Explain how an organism’s metabolism is related to Earth’s carbon cycle. An organism’s metabolism is related to using energy to build organic molecules which contain carbon or breaking down organic molecules in which energy is stored. Because of this, an organism’s metabolism is a part of the Earth’s carbon cycle. This cycle make carbon compounds continuously available in an ecosystem and deliver chemical energy to organism living within that ecosystem 3. Describe how energy is released from ATP. ATP is made up of an unstable chain of 3 phosphate group because they are all negatively charged and thus repel each other. The energy that was stored is released during the breaking of the 3rd bond. This energy can be released as heat or power in cell in order to help perform chemical activities. ATP can be used to contract muscle cell, actively transport a protein or help make more ATP. Critical Thinking 4. Analyzing Patterns Explain how life involves a continuous flow of energy. The law of conservation of energy states that the total amount of energy is an isolated system remains constant. The consequence of this law is that energy cannot be created nor destroyed. Energy can be converted or transformed into another form of energy. We can’t create more energy. A certain amount of energy will always be lost, usually as heat, to the environment. Therefore, when we use glucose and other products to maintain our bodies, we generate heatas a â€Å"waste product†. Heat is also lost at each step as we go up the food chain, until all the energy trapped by plant is liberated as heat. Thus, energy does flow through life, or a system. At one point it was sunlight, at another point glucose, another point biomass consumed, and as heat finally. 5. Inferring Relationships How can the energy in the food that a fox eats be traced back to the sun? Fox in general or red fox may consume birds or small mammals like squirrels, rabbits and mice. And as we know, squirrels eat fruits, nuts and seeds. These are products of plants, or autotrophs. Autotrophs make their own food through photosynthesis. However, it would be impossible for them to produce organic compounds from CO2 and H2O without sunlight. Therefore, the energy in the food that the squirrels eat, which the fox eats, came from the sun. 6. Summarizing Information What is the difference between cellular respiration and the process by which energy is released from a burning log? When the log burns the chemical energy stored in wood molecules is released in a burst of heat and light. While during a cellular respiration, stored chemical energy is released gradually in a series of enzyme-assisted reactions. Cellular respiration takes place in the mitochondria. This process is the breaking down C6H12O6 and burning it with O2 in a combustion or water yielding reaction to form CO2 and H2O while burning a log is an exothermic reaction which is caused by the burning of Hydrocarbon in the presence of O2.

Assignment in law (Legal Issues Relevant to the Quality of the Website Essay

Assignment in law (Legal Issues Relevant to the Quality of the Website and Indecent Images of Children, Invention Law, Expert Witness) - Essay Example Synergy Ltd, the company in which I am a systems manager does not want to be left out of the internet technology and its benefits. Therefore, the company has sought to develop a website in order to attract clients in the wake of the economic downturn. The website will provide relevant contact information, technical information, and a discussion group allowing registered users to discuss problems, and allow them to estimate the charge for recovering information. The company has sought the services of a developer to develop its website. There are legal issues that are relevant to the quality of website delivered by the developer and to protecting the company from problems. These issues include the following: private and security issue and legal liability issue. According to Baumer, Lyengar, & Moffie, (2003, p. 23), the issue of privacy and security is one of the main issues that surround creation of websites. Websites are crucial for storing and selling of information that benefits both the businesses and the consumers. However, there is a concern among businesses and consumers regarding their personal safety and privacy of their personal and other sensitive information. This concern is compounded by the ease with which information may be cross processed and collected from websites. In the United Kingdom, the issue of website security and privacy is covered under the Data Protection Act 1998 and Privacy and Electronic Communications Regulations 2003 (Defago and Bockanic, 2006, p. 205). These Acts requires that cookies should be signposted on the websites. In addition, they require that visitors of the websites should be allowed to refuse or accept their personal details to be collected and used in the websites. Also, the Acts requires that personal information that is collected concerning individual visitors should be used or processed in accordance to the principles and provisions set out in the Privacy Regulations and the Data Protection Acts. More importantly, these Acts seek to protect businesses in an event that commercial relationships become ruined, as was demonstrated in the case of Ashton Investments v OSJC (2006). In this case, OSJC (a Russian company) employed spyware to the computer system of its former business partner, Ashton Investments, to hack illegally private information relating to the litigation between them. In the light of these two Acts and the need to protect the business in an event of ruined relationship between the company and its business partners, the developer of the website should ensure that the website has a high level of privacy and security. In regard to the issue of legal liability, it is important to point out that the utilization of Wide Web has prompted businesses to venture in unexplored business frontiers. As such, they are more likely to be exposed to legal risks. This issue has been exacerbating by the fact that most laws relating to cyberspace in both criminal and civil dimensions are still in comparative legal infancy. The legal liability issues relating to websites are copyrights, infringement of copyrights, website development contracts, appropriation of names, and defamation (Baumer, Lyengar, & Moffie, 2003, p. 24). In addition to under the Data Protection Act 1998 and Privacy and Electronic Communications Regulations 2003, Digital Economy Act 2010 makes legal provisions for website and internet. The Act has provisions that seek

Network Security Outline Example | Topics and Well Written Essays - 4250 words

Network Security - Outline Example Network security has advanced from a fascinating curiosity to a vital rather essential part of the network management activity for potential corporate users in all sectors of the economy. Successful test projects are helping an increasing number of institutions to make the shift towards incorporating security measures in their organizations. In the recent past, last decade, network security implementations have shifted the focus from the relatively small early adopters to a much larger group of organizations that use the network security to expand and comprehensively cover the networking capabilities and enhance their solicitation to their clientele. This report examines the state security implementation on an organization’s network based on the success stories and perceived benefits. It examines the objectives, background and level of detail into implementing the service. Further, the report incisively looks at the motivation for making the technological shift from wired infrastructure to wireless networking solutions and nature of the expected implementation Majority of the existing organizations, commercial and non commercial, have in the very least installed a certain security mechanism in their organizations. This comes in the form of simple firewall to a complex layered network of switches, routers etc. in a single room to rolling out large campus areas and few metropolitan area networks. Granted the continuing forecasts and advances for network technology and the pervasive use of network applications., the era for implementing tight network security in an organization is at hand. Organizations are growing increasingly concerned about security of their data, especially as the very value of their data continues to increase. This value refers to what strategic and planning information that the data can be used for. Network security has been overlooked in this rising awareness about security. It is often not possible to put a price tag on the stored data but the organization knows that it is its most valuable asset. Compromising or expo sing the information can cause them pervasive damage of their brand and reputation. Organizations ought to adopt security strategies, for instance, tagging data with a level of confidentiality to make sure only those permitted have access to such data (Connolly and Begg 2009). Security strategies are designed as the overall plans to mitigate risk. As mentioned earlier, most organizations have security strategies, but miss out on network security or do not adequately address the issue. A comprehensive security strategy must lessen the overall possibility of loss or harm to an organization’s data. Furthermore, the strategy must focus on the business data concerns from a statutory, contractual and legal perspective. There exist multiple regulatory standards and requirements that have imposed on the organization to address information security risks. Contracts are making it necessary to organizations to consider security of their data at all levels. Proactive network security man agement and planning can save organizations significant amounts of money and reduce the overall exposure to risk. Striking a balance between the organizational objectives and security requirements is a task that squarely falls on the IT department. They are charged with developing the ICT policy for companies in consultation with
