The diagram shows a cell during the anaphase stage of mitosis. How would this diagram be different if it showed anaphase I of meiosis instead of anaphase of mitosis? Each chromosome would still have two chromatids together. The chromosomes would look the same as in mitosis. You would be able to see DNA in the chromosomes during meiosis. Homologous chromosomes would be moving to the same end of the cell. Solution Answer is A Each chromosome still have two chromatids together, which will further divide in anaphase II. Thus giving 4 daughter cells..

Should Maria’s ethical responsibility to Linda lead her to keep these concerns to herself and allow the recommendation to stand? Solution Ethical responsibility mainly is used to follow the right path. Here, the actions of an individual must benefit the whole society. So a person should speak up for the right thing. Every individual is accountable for fulfilling their civic duty, even small business owners also have ethical responsibilities to their employees, customers and society as a whole. So if Maria feels there is something that would affect their customers, environment, business and society as a whole, she should not keep her concerns to herself.

SNMPv1 (Simple Network Management Protocol) v1 was designed as a short term solution to allow management of TCP/IP - based internets. Although it was simple there were some major issues in SNMPv1, viz Expressiveness of MIB definitions, performance and security issues. Some key differences brought in SNMPv2 are: Answer 2: The newer version of SNMP, i.e. SNMPv3 was released to cover some of the security issues that plagued SNMPv2. SNMPv3 framework augments the original SNMP and SNMPv2 specifications with additional security and administration capabilities. Security and remote configuration capabilities were added in the newer version. The SNMPv3 architecture introduces the User-based Security Model (USM) for message security and View-based Access Control Model(VACM) for access control. The architecture supports the concurrent use of different security, access control and message processing protocols. SNMPv2 also introduces the ability to dynamically configure the SNMP agent using SNMP SET commands against the MIB objects that represent the agent\'s configuration. The dynamic configuration support enables addition, deletion and modification of configuration entries locally or remotely. The latest architecture incorporates an SNMP context engine ID to encode and decode SNMP contexts. In short, SNMPv3 provides three layers of security. The highest level is with authentication and privacy. The second or middle level is with authentication and no privacy and the bottom level is without authentication and privacy. Answer 3: Remote Monitoring (RMON) is a standard specification that facilitates the monitoring , analyzing and troubleshooting of network operational activities through the use of remote devices known as monitors or probes. RMON provides the benefits of standarazation and improves efficiency by allowing you to remain at one workstation and collect information from widely dispersed LAN segments or VLANs. RMON also allows proactive management and reduces the traffic load. Answer 4: Microsoft network monitor and CapsaFree are a few of the basic tools one can use for in this case.

Pretend you have been asked by the president of the united statesto chair a special task force that is to write a national policy statement on children\'s exposure to television. What recommendations would you make concerning viewing hours and type of shows to be aired? Relating television back to cognitive development, give two examples of how young children might misunderstand plots of television shows or claims made on advertisements. Solution individuals suffering from social isolation can employ television to create what is termed a parasocial or faux relationship with characters from their favorite television shows and movies as a way of deflecting feelings of loneliness and social deprivation.Just as an individual would spend time with a real person sharing opinions and thoughts, pseudo-relationships are formed with TV characters by becoming personally invested in their lives as if they were a close friend so that the individual can satiate the human desire to form meaningful relationships and establish themselves in society. The pleasurable effects of television may be likened to an addictive activity, producing \"momentary pleasure but long-term misery and regret.\"When a person plays video games or watches TV, the basal ganglia portion of the brain becomes very active and dopamine is released.Release of high amounts of dopamine reduces the amount of the neurotransmitter available for control of movement, perception of pain and pleasure and formation of feelings.Watching television starting at a young age can profoundly effect children\'s development. These effects include obesity, language delays, and learning disabilities. Physical inactivity while viewing TV reduces necessary exercise and leads to over-eating. Language delays occurs when a child doesn\'t interact with others. Children learn language best from live interaction with parents or other individuals. Resulting learning disabilities from over- watching TV include ADHD, concentration problems and even reduction of IQ. Children who watch too much television can thus have difficulties starting school because they aren\'t interested in their teachers. Children should watch a maximum of 2 hours daily if any television. At the same time, television can help young people discover where they fit into society, develop closer relationships with peers and family, and teach them to understand complex social aspects of communication. Recommendations are: Give a specific time,ie, like 2 hours/day for television watching and engage them in oter leisures such as sports,arts,etc.The type of shows must be informative,such as about new hobbies,improvements in science and technology and new discoveries or about great people.Never go for anything like dating shows or something explicit children..

Please explain in detail. Why can\'t Salmonella be infected by lambda phage? Why can\'t salmonella be successfully transfected using lambda DNA? Solution Lambda phage is a bacteriophage or bacteria virus which is known to infect bacteria especially Escherichia coli hence, sometimes also called as coliphage.This virus is used in recombinat DNA technology for transferring special genes or you can say that as a vector. To infect a bacterium a virus needs to: 1) interact first with the cell surface receptors which are different in different species thus, making coliphage entry difficult inside the Salmonella species. 2) Multiplication of virus genome inside the bacteria is another factor for a virus to cause infection in a bacterium. To multiply inside bacteria, phage join its nucleic acid with host\'s nucleic acid, this stage of infection is called prophage. To attach its nucleic acid a phage must recognise an attachment site called att site in host\'s genome which varies among different genera. At this stage genetic exchange takes place hence, it is difficult too transfect Salmonella with a coliphage. However, Phage P22 can transfect Salmonella because the bacterium has specific att sites for P22. Also, Transduction i.e. transfer of nucleic acid by a bacteriophage to bacteria was first discovered in P22 infecting Salmonella. Salmonella species can be made competitive( susceptible to genetic exchange by transfection) for coliphage by altering its genomic structure using recombinant DNA tools..

Part 2: Name and briefly describe two ways that college students could be recruited into illegal espionage. Part 3: Explain the function of the trusted boot function of the trusted platform module (TPM.) Tell how that is related to the current controversy between Apple and the FBI concerning encryption. What could the FBI do in the absence of a trusted boot function? Part 4: Define single loss exposure and annualized risk of occurrence. Explain in your own words what these have to do with computer security. Part 5: Explain why it is important to monitor outbound traffic as well as inbound traffic in a corporate network. Give an example Solution Part1:- There are three things that can enhance operating system security across an enterprise network: First, provisioning of the servers on the network should be done once in one place, involving the roughly tens of separate configurations most organizations require. This image, or set of images, can then be downloaded across the network, with the help of software that automates this process and eliminates the pain of doing it manually for each server. Moreover, even if you had an instruction sheet for these key configurations, you wouldn\'t want local administrators to access these key configurations for each server, which is very dangerous. The best way to do it is once and for all. Once the network has been provisioned, administrators need to be able to verify policy compliance, which defines user access rights and ensures that all configurations are correct. An agent running on the network or remotely can monitor each server continuously, and such monitoring wouldn\'t interfere with normal operations. Second, account management needs to be centralized to control access to the network and to ensure that users have appropriate access to enterprise resources. Policies, rules and intelligence should be located in one place—not on each box—and should be pushed out from there to provision user systems with correct IDs and permissions. An ID life cycle manager can be used to automate this process and reduce the pain of doing this manually. Third, the operating system should be configured so that it can be used to monitor activity on the network easily and efficiently—revealing who is and isn\'t making connections, as well as pointing out potential security events coming out of the operating system. Administrators can use a central dashboard that monitors these events in real time and alerts them to serious problems based on preset correlations and filtering. Just as important, this monitoring system should be set up so that administrators aren\'t overwhelmed by routine events that don\'t jeopardize network security.

List three characteristics that an Intrusion Prevention System (IPS) could use in identifying an intruder to a network. Do you feel these systems are effective? Solution Intrusion Prevention System is a control device of security technology where it has the capacity which it offers the security to all the system levels. That is, it provides the security from the operating system to network data packets. When the data is transferred by the user, the IPS offers some rules for the network traffic for alerting the user system or the network administrators by giving alert that there will be a suspicious in the traffic. Then the administrator can take the action on the suspicious and user can be attentive. If there are any potential attacks then IPS makes attempts to stop it. IPS has the capacity that it prevents the known intrusion signatures, and also some unknown attacks. Yes, it is an effective system to avoid the attacks and protects the system in all levels by providing the security..

In the early 1900s. there was considerable debate about whether protein or DNA was the hereditary material. For what reasons did many researchers assume that protein was the genetic material? What key sets of experiments led to the understanding that, in fact. DNA and not protein was the hereditary material? What evidence did each experiment provide? Solution Answer a. Scientist thought that almost everything inside the cells is done by protein also they gave the rationale behind this is due to fact that if something complex or any important thing that is being done inside the cell is may be due to protein At that time, it was known that proteins are made up of 20 amino acids and DNA is made up of 4 different nucleotides. This might lead them to thought that protein could be genetic material since it creates multiple variability as compared to DNA. What key set of experiments that led to the understanding that, in fact, DNA not protein was the hereditary material? What evidence did each experiment provide? Griffiths transformation experiment on mouse He used two different strains of Streptococcus pneumoniae. One stain was virulent and other one was virulent. He boiled both the strain and infected them to mice. But mice survived. Then he done another experiment where he mixed heat killed virulent strain with live avirulent strain. Upon injecting the mixture, the mice died. Upon isolation of the strain he found virulent strain from dead mice. Since protein denature upon heating so proposed that some material transfer from heat killed virulent strain and passes into avirument strain which is the cause of mice death. This experiment first indirect proof which showed that DNA not protein is the genetic material. Harshey and Chase Experiment They used 35sulphur and radio 32phosphorus. Since phosphorus is found in DNA not is proteins same way sulphur is found in proteins not in DNA. They incorporated radiolabelled isotopes into the T phage and transduce onto their host. When phage will multiply in the host their genetic material will also divide. But not the phage ghost. After multiple cycle, they blend the cells and centrifuge them. When they check the radioactivity in supernatant where phage ghost present and pellet where bacterial cells were present they found 32phosphorus in the pellet where bacterial cells were present and 35sulphur in supernatant containing phage ghost. Phage incorporate their DNA into the bacterial DNA so this lead the detection of 32phosphorus in bacterial pellet. What key set of experiments that led to the understanding that, in fact, DNA not protein was the hereditary material? What evidence did each experiment provide? Griffiths transformation experiment on mouse He used two different strains of Streptococcus pneumoniae. One stain was virulent and other one was virulent.

Babies younger than 1-month-old and people with weakened immune systems are more likely to have severe illness. The most common cause viral meningitis is by non-polio enteroviruses. This group of viruses include coxsackievirus A, coxsackievirus B and echoviruses. Other viruses which cause meningitis include mumps virus, herpes virus, measles virus and influenza virus. The symptoms include fever, headache, sensitivity to light, nausea, vomiting and lack of appetite in adults. In children they have symptoms like poor eating, sleepiness and lethargy. There is no specific treatment for viral meningitis but most people completely recover within 7 to 10 days. People infected with certain viruses like herpesvirus and influenza will usually need treatment such as antiviral medicine..
