What is the evolutionary basis for sexual reproduction? Solution There are both asexual and sexual reproduction in nearly all groups of animals and plants, in neither kingdom sex developed as a more rapid means. When sexual reproduction first originated is still a question. But it is believed that sex originated in green algae. There are certain species like Ulothrix have different size of spores are produced. These spores comes in pair and become one and gives valuable new forms. In some groups of unicellular plants ,the Peridinea, the Conjugatae and the Diatomeae- there is no asexual reproduction. These are good example of the actual gametic origin. The whole process of evolution is understand by these lines that first there was a visible morphological differentiation of gametes, the one becoming a large inactive cell stored with food , the other becoming small and mobile. Then came the evolution of various sex organs, and finally the alternation of generation. There are 3 main categories of sexual life cycles: diploid-dominant, demonstrated by most animals; haploid - dominant, demonstrated by all fungi and some algae; and the alternation of generations , demonstrated by plants and some algae. The Red Queen Hyothesis- First proposed by Leigh Van Valen in 1973. According to this hypothesis are species co-evolved with other organisms like predators evolve with their prey and parasites evolve with their hosts. Each tiny advantages gained by favorable variations gives a secies an edge over close competitors, predators, parasites, or even prey. Species that cannot keep up become extinct. August Weismann proposed an explanation for the evolution of sex, where the advantages of sex is the creation of variation among siblings. A similar hypothesis proposed by Charles Darwin in his book Origin of species..

Why is it that the Gram\'s stain is not appropriate for acid fast bacterium? Solution During staining in microbiology, microbes are coloured or dyed so that their structure can be viewed against a lighter background. There are different staining techniques such as direct(Dye binds to the cell surface and all the microbes are stained alike),differential(based on their specific cell surface different microbes get stained differently) special (usually a particular organelle is targeted)and negative staining(back ground is stained instead of microbes) Gram stain is a differential stain where the bacteria with a thick peptidoglycan layer around the cells are stained with violet colour and those with an additional lipopolysaccharide layer will be stained pink. To understand this lets take a look at Gram staining procedure. First of all bacterial culture is smeared onto a glass slide and is heat fixed so that during the washes in the procedure the bacteria stay fixed onto the slide. Primary stain crystal violet is added onto the slide and the dye seperates into ions which penetrate or enter the cell membranes of both Gram positive and negative cells. Next iodine is added onto the slide which forms huge complexes with crystal violet. Then a dye remover usually called as decolouriser such as alchohol or acetone is used to remove the stain. In Gram negative bacteria the outer most membrane is lost during the treatment with alchohol whereas in the case of gram positive bacteria the dye is trapped inside the cell membrane. A secondary stain saffronin is used and which gives pink colour to Gram negative bacteria. Now coming to acid-fast bacteria, they have a compound called mycolic acid in their cell walls and are resistant to decolourisation after the acid treatment and alchohol and hence would not lose colour and appear violet. As we can see these organism can be easily confused with Gram positive bacteria which also do not lose stain not because they are resistant to acids but they have the crystal violet dye trapped in their cell membrane..

Why does this version of the swap function fail to work? Is there a fix? (Choose 2) oid swap (int & lhs, int & rhs) Select one or more: It fails because the programmer forgot to make the parameters call-by-reference. Of course it works ! Just look at it It clearly swaps the two parameters! It fails OK, and we can fix it we can just reverse the order of the lines. To fix this, we must save the the value in a local variable before making the first assignment indicated, then instead of the second Iine, as int local = lhs; Ihs = rhs; rhs = local; It fails because the first line destroys the old value of ihs without saving it. Then both variables have the old value of rhs in them. Solution Choice d, and e are valid options. To swap the elements, we need to first copy the value of first variable to temporary variable, then copy the second variable to first variable, finally copy the value in temporary variable to second variable. So, int local = lhs; lhs = rhs; rhs = local; is the perfect way to swap two values. The last option is the actual problem with the given code. When we do lhs = rhs, the old value of lhs is destroyed, and now, both lhs and rhs are holding the same value, that is the value in rhs. And then, the second operation rhs = lhs, is of no use, as both of them are holding the same value. Therefore, options d, and e are correct..

Security Challenges\" Please respond to the following: Distributed applications and cloud computing have become a viable option within the LAN-to- WAN Domain. Discuss the primary challenges related to maintaining the security of both applications and data in such an environment. Describe the controls that are needed to ensure the security of distributed applications and data. Identify the auditing approach that you believe is best suited to this arrangement. Provide a rationale for your response. No plagiarism please. Solution Challenges in Distributed applications : 1) Computational problems:- Those kind of problems which cannot be resolved within a specific amount of time on a single computer. 2) Scalability:- The system has to remain effective enough so that it can handle the increase in the number of resources and users. 3) Security:- In Distributed applications, the possible threats could be the information leakage, integrity violation, DoS(Denial Of Services) , illegitimate usage of the system. 4) Concurrency:- The shared access to the resources should be handled properly. Challenges in Cloud computing : 1) Security & Privacy:- The fact that the organization\'s data will reside outside the organization\'s firewall really raises a serious concern. Various types of attacks including hacking may affect multiple clients even if only one site is attacked.These risks has to be mitigated by using proper security applications, encrypted file-systems, using a proper storage devices to track unsual activity across the servers . 2) Loss of control over sensitive data:- The sensitive data that are stored in the servers has to be properly controlled. 3) Reliability and Availability:- The frequent outages has to be avoided here. It is very important to monitor the activity of servers using monitoring tool. The controls that are essential to prevent security threats in distributed applications and data include: 1) The control should protect data and integrity of system in case of invalid operation on secured data:- In case, a user tries to enter invalid data into the system, the control should protect the system from such operations. 2) Unauthorized invocations should be rejected by security control. 3) Efficient protection against unauthorized users:- Unauthorized access request by non-system users should be rejected by the control. The auditing approach should firstly start by ensuring data integrity that is associated with application. Control should specify the operation that can be invoked only by authorized person while rejecting access to unauthorized users when the data resources are accessed. Irrespective of operation, control should select only that user which can be allowed access while restricting others non-system users. Rules should be strictly followed by control and on the basis of defined rules, users access should be granted or denied..

Why can’t an attacker masquerade by using a hashed password? 6. Explain how biometric systems are vulnerable to the five generic attacks on authentication systems. a. Clone or borrow credential b. Sniff credential c. Trial and error guessing d. Denial of service e. Retrieve from backup Solution 1) and 6) 1.Clone or borrow the credential or token - copy of the credential itself and uses it to log in. 2.Sniff the credential - intercepts and copies it while being transmitted to the login process. 3.Trial-and-error guessing - simply guess several words or names. 4.Denial of service - attack either damages the system or blocks access to it by others. 5.Retrieve from backup - find the authentication database or other information on a backup copy of the hard drive 2) Hashing is the transformation of a string of characters into a usually shorter fixed-length value or key that represents the original string. Hashing is used to index and retrieve items in a database because it is faster to find the item using the shorter hashed key than to find it using the original value. It is also used in many encryption algorithms >As a simple example of the using of hashing in databases, a group of people could be arranged in a database like this: Abernathy, Sara Epperdingle, Roscoe Moore, Wilfred Smith, David (and many more sorted into alphabetical order) >Each of these names would be the key in the database for that person\'s data. A database search mechanism would first have to start looking character-by-character across the name for matches until it found the match (or ruled the other entries out). But if each of the names were hashed, it might be possible (depending on the number of names in the database) to generate a unique four- digit key for each name For example: 7864 Abernathy, Sara 9802 Epperdingle, Roscoe 1990 Moore, Wilfred 8822 Smith, David (and so forth) >A search for any name would first consist of computing the hash value (using the same hash function used to store the item) and then comparing for a match using that value. It would, in general, be much faster to find a match across four digits, each having only 10 possibilities, than across an unpredictable value length where each character had 26 possibilities. >The hashing algorithm is called the hash function-- probably the term is derived from the idea that the resulting hash value can be thought of as a \"mixed up\" version of the represented value..
