This week you surveyed many different groups of living things. What Domain of living things is thought to have been the first form of life on Earth? Name one piece of evidence that exists for the claim that these were the earliest living things? Solution Archaea are found in the harshest environments on Earth, and are the oldest known organisms on Earth, appearing in the fossil record over 3.6 BILLION years ago Archaea display unique capacities, such as methanogenesis and survival at temperatures higher than 90 °C, that make them crucial for understanding the nature of the biota of early Earth..

The restriction enzyme EcoRI recognizes a 6 bp (palindromic) sequence. On average, how often would this enzyme cut a random sequence of DNA? How many times would the enzyme cut the E. coli genome? (The E. coli genome contains 4.6 x 106 bp). Solution There are 4 types of bases so the chances of each base to cut in the sequence is (1/4) (1/4) (1/4) (1/4) (1/4) (1/4)= (1/4)6 base pairs=1/4096. Now as the DNA sequence is completely random and we can expect that the enzyme may cut the DNA once every 4096 bases. Now the E.coli genome contains 4.6 x 106 base pairs of sequence. Then the cutting site will be in the whole E.coli genome is (4.6*106 /4096)= 1123 times..

There are several types of bacterial toxins that are categorized as spreading factors. One of those is leukocidins. Do the 3 species of staphylococci you\'ve described produce leukocidins? What is their function? How do they work? Solution Leukocidins are toxins secreted by Staphylococcus aureus, Streptococcus pyogenes, and S. pneumoniae Among the three important Staphylococci, viz., S. aureus, S.epidermidis, and S.saprophiticus, leukocidins play a major role in the pathogenesis of S. aureus. Leukocidins are toxins that kill leukocytes (lit., Leuko: for leukocytes and caedo: killing) with or without lysis. In Streptococcus aureus, they attacks neutrophils, disrupt their membrane that leads to the release of the lysosomal contents, thereby, killing them..

Please help!!! I can change a link layer protocol and the application layer protocol does not need to know or be made aware of the change. Explain why? Solution Answer :- The protocols are like a pile of building blocks stacked one upon another. Because of this appearance, the structure is often called a stack or protocol stack. A layer does not define a single protocol it defines a data communications function that may be performed by any number of protocols. Therefore, each layer may contain multiple protocols, each providing a service suitable to the function of that layer. For example, a file transfer protocol and an electronic mail protocol both provide user services, and both are part of the Application Layer. 1) Application Layer :- The Application Layer is the level of the protocol hierarchy where user-accessed network processes reside. In this text, a TCP/IP application is any network process that occurs above the Transport Layer. This includes all of the processes that users directly interact with as well as other processes at this level that users are not necessarily aware of. 2) Presentation Layer :- For cooperating applications to exchange data, they must agree about how data is represented. In OSI, the Presentation Layer provides standard data presentation routines. This function is frequently handled within the applications in TCP/IP, though TCP/IP protocols such as XDR and MIME also perform this function. 3) Session Layer :- As with the Presentation Layer, the Session Layer is not identifiable as a separate layer in the TCP/IP protocol hierarchy. The OSI Session Layer manages the sessions (connections) between cooperating applications. In TCP/IP, this function largely occurs in the Transport Layer, and the term “session” is not used; instead, the terms “socket” and “port” are used to describe the path over which cooperating applications communicate. 4) Transport Layer: Much of our discussion of TCP/IP is directed to the protocols that occur in the Transport Layer. The Transport Layer in the OSI reference model guarantees that the receiver gets the data exactly as it was sent. In TCP/IP, this function is performed by the Transmission Control Protocol (TCP). However, TCP/IP offers a second Transport Layer service, User Datagram Protocol (UDP), that does not perform the end-to-end reliability checks. 5) Network Layer :- The Network Layer manages connections across the network and isolates the upper layer protocols from the details of the underlying network. The Internet Protocol (IP), which isolates the upper layers from the underlying network and handles the addressing and delivery of data, is usually described as TCP/IP’s Network Layer. 6) Data Link Layer :- The reliable delivery of data across the underlying physical network is handled by the Data Link Layer. TCP/IP rarely creates protocols in the Data Link Layer. Most RFCs that relate to the Data Link Layer discuss how IP can make use of existing data link protocols. 7) Physi.

Explain the basic characteristics of a partnership. Solution There must be at least two or more persons to form Partnership. There must be agreement between partners and such agreement can be Oral or Written. The agreement forms the basis of Mutual rights and duties of Partners. Partnership can be formed for the purpose of carrying on some business with the intension of earning some profit. The Agreement must include how the profit or loss to be shared. If the persons joins firm for some Charity then it will not be called partnership and if the persons is deprived of his right to share the profit then he/she will not be called partner. And it is not necessary that all partner share loss also, it may be agreed between partners that some oo one of the partners will not be liable for losses. All the persons have Unlimited liability i.e. if the assets of the company is not sufficient to pay the liabilities then the Creditors can come after the personal property of the Partners. In the eyes of Law, A partner and Partnership firm are same, i.e. Partnership firm doesn’t have its own Legal identity. The business must be Legal..

Explain the functions of the different types of meristems found in plants. Be able to distinguish between secretory tissues. Solution In plants, meristems are resent broadly of three types namely: 1. Apical meristem 2. intercalary Meristem 3. Lateral meristem 1. APICAL MERISTEM This is present at the root and shoot apex of the plant and is actively dividing zone. Shoot apcal meristem causes plant to grow up and root apical meristem causes thr roots to grow down in the soil. Apical meristems keep dividing and result in the primary growth of plant and the tissues formed as their division as named as Protoderm and Procambium. 2. INTERCALARY MERISTEM Intercalary meristem is found between the mature tisues like nodes and internodes. It functions to regulate the regenration of Tissues when the leaves and grasses are grazed by herbivores. This meristem is found mainly in monocot plants. 3. LATERAL MERISTEM This type of meristems is developed late in the plant life cycle and thus it is also known as secondary meristem. It functions in the secondary growth of plant where plant grows in girth not in height. Cork cambium fascisular cambium and interfascicular cambium are types of lateral meristems..

Consider the security of a personal computer. List a few of the attackers who might break into the computer, their incentives, and the associated costs and risks to the attacker. Solution A top-down approach to identifying threats and countermeasures, CISOs should consider a threat modeling technique allows the target application to be decomposed to reveal its attack surface and subsequently its relevant threats, associated countermeasures, and finally, its security control gaps and design flaws. applications are also a source of potential risks especially when new or different technologies are integrated within applications. As applications evolve by offering new services to citizens, clients, customers and employees, it is also necessary to plan for mitigation of new vulnerabilities introduced by the adoption and implementation of new technologies such as mobile devices, web 2.0 and new services such as cloud computing. Adopting a risk framework to evaluate the risks introduced by new technologies is essential to determine which countermeasures to adopt to mitigate these new risks. threat agents seek financial gain such as by attacking applications to compromise users\' sensitive data and company’s proprietary information for financial gain, fraud as well as for competitive advantage the risks posed by these threat agents, it is necessary to determine the risk exposure and factor the probability and the impact of these threats as well as to identify the type of application vulnerabilities that can be exploited by these threat agents. The exploit of some of these application vulnerabilities might severely and negatively impact the organization and personal computer. data from legal in relation to law suits and regulatory fines and fraud data that includes amount of money losses incurred because of online fraud. All this type of information is essential to determine the overall impact. In absence of this data, the best the CISO can do is to use data breach incident data from public sources and data breach incident reports. In part I of this guide, we provided some examples of how this data can be used to estimate impact. We documented what are the critical factors to estimate impacts of data breaches: these as the value of the data assets liability for the organization in case these assets are lost. Once the potential business impact of a data breach is estimated, the next step is to determine how much should be spent to mitigate the risk. At high level, this is a risk strategy decision that depends on the organization risk culture and the organization priorities for mitigating risks..
