Wolves were hunted and poisoned to extinction in Sweden and Norway by the mid-20th century. Three wolves migrated from Russia and founded a new Scandinavian wolf population in the early 1980s. That population now consists of approximately 100 animals. How large do you think the Scandinavian wolf population should be to maintain genetic variation that may be important for the viability (continued persistence) and continued evolution of this population? There is some possibility of gene flow into this population from Russian wolves. Do you think that it is important that gene flow between the Scandinavian and the Russian populations be maintained in the future? Why? Solution There is no cut-off formula for calculating the length of population to maintain genetic diversity. It is important to note that even after bottleneck effect populations are able to survive and are able to maintain genetic diversity. Here, there are 100 animals; and these 100 animals are heterozygous, not pure lines; because they have already mixed up with the Scandinavian population. So, the population is large enough to maintain genetic variation. Yes, there is further possibility of mixing of this population with Russian wolves further also; but that possibility is very rare. This is so because wolves have already been extinct over there; as per the question. No, it is no more compulsion for gene flow between the two populations. This is so because the populations have already diverged. And a subsequent amount of genetic variability has been attained..

Declaring a Pointer To define a pointer, use an asterisk, (*), in the declaration to specify the variable will be a pointer to the specified data type. Recall that the name of an array holds the memory address of the first element of the array. The second statement then would store the memory address of the first value in the variable valuePtr. The name of a pointer is an identifier and must follow the rules for defining an identifier. Some programmers place the letters ptr, a common abbreviation for pointer, at the end of the variable name, others prefix a pointer with p_ or ptr_, and there are those who do nothing to distinguish a pointer by its name. The naming of a pointer variable is a matter of programming style. Once a pointer has been declared and initialized, it can be used to access the data to which it points. In order to access this value, the dereference operator, *, must be used to prefix the name of the pointer. From the code above, valuePtr holds the address of the first element of the values array; therefore, *valuePtr will access the value 325. Add the following to main and execute the program. The output generated should look something like the following. Where 0xbfad43e8 is a memory address displayed in hexadecimal. Obtaining the Memory Address of a Variable The address operator, &, is used to determine the memory address of a variable that is not an array. Add code necessary to use fixed and setprecision, then add the following to main and run the program to confirm the use of the address operator. Using a Pointer to Alter Data Just as the dereference operator is used to retrieve data, so too is it used to store data. Add the following to function main and run the program. The pointer, ratePtr, is used to change the data stored in payRate. The output of payRate confirms the change. Using a Pointer in an Expression As previously shown, the value pointed to by a pointer variable can be retrieved by dereferencing the pointer. In the above code, the retrieved value was simply displayed to the screen; however, it can also be used in an expression. Add the following to main and execute the program. Pointer Arithmetic It is possible to add to or subtract from a memory address stored in a pointer. These actions can be accomplished using the addition operator,+, subtraction operator, - and the increment and decrement operators, ++ and --. This is helpful when accessing arrays via pointers. The increment operator has been used to add the value 1 to a variable. When used with a pointer, the increment operator adds the size of the data referenced to the memory address stored in the pointer, effectively moving the pointer to the next data value. Building on the code from above, add the following to main and execute the program. We initialized valuePtr to the memory address of the first element of the array values. Incrementing valuePtr instructs the computer to add four bytes, the size of an integer, to the memory addressed stored in .

Which of the following concepts is exemplified by the story of Parus major and the island of Vlieland? Gene flow reduces the genetic differences between populations. Gene flow can affect how well populations are adapted to local environmental conditions. Genetic drift is significant in small populations. Genetic drift can lead to a loss of genetic variation within populations. Relative fitness is not the same as fitness when calculated on a 0-1 scale. Solution ANS: E. Relative fitness is not the same as fitness when calculated on a 0-1 scale. Explanation: Ex: the great tit (Parus major) on the Dutch island of Vlieland. In Parus major high immigrated central region birds have a lower fitness, when compare with the low immigration birds which are present in east. This phenomenon clearly explains low immigrated birds had higher fitness. Definitions of Other Terminology: Darwin\'s fitness: It is the ability of an individual to survive and reproduce in its environment. Fitness of an organism is measured by how many offspring it produces compared to other individuals of a species. Adaptation refers to the trait that increases organism fitness relative to individuals without the trait. Genetic drift: It is random and happens in every population due to chance. Because of this smaller population are more susceptible to the effect of genetic drift. Gene pool: Gene pool is a reservoir of all genes, which was present in a population. Gene pool corresponds with a number of unique alleles present in a population..

What are the main challenges to be dealt within a distributed operating system? 150 words expected. Solution Challenges in the distributed operating systems do not come for free. Some challenges need to be beat in order to get the perfect systems. The challenges in distributed systems are: Heterogeneity: is the variety of the distributed systems in terms of hardware, software and platforms Transparency: Distributed systems designers hide the complexity of the systems as much as they preserve. Addition of abstraction layer is particularly helpful in distributed systems Concurrency: Concurrency is a tricky challenge and then we must keep away from the systems state from becoming unstable when the users compete to view or update the data Security: Every system must consider strong security height. Distributed Systems somehow deals with responsive information.

What networking challenges does for the Open Ethernet address and how does it improve them? What would be some of the future business demands on data networks that Open Ethernet would satisfy? Solution 1)Answer: challenges: If a networked Layer 2 device such as a bridge or LAN switch could contain a list of all known MAC addresses, then the network node could function in much the same way as a router, forwarding frames instead of packets hop-by-hop through the network from source LAN to destination LAN. However, the MAC address is much larger than the IPv4 address currently used on the Internet backbone (48 bits compared to the 32 bits of IPv4). This poses problems. Also, because the MAC address has no “network organization” like the IPv4 or IPv6 address, an Layer 2 network node must potentially store every conceivable MAC address in memory for next-hop table lookups. Instead of tables of about 125,000 entries, every Layer 2 network node would have to store millions of entries. Improvement: Wireless access points often use MAC addresses for access control. They only allow access for known devices (MAC address is unique and identifies devices) with the correct passphrase. DHCP servers use the MAC address to identify devices and give some devices fixed IP addresses. uses: Hotels, restaurants and bars are increasingly being pushed to offer ubiquitous and free WiFi – in hotel rooms and also in all common areas. Travelers and patrons, now used to having access anywhere, at any time for their multiple smart devices, demand connectivity and choose where to patronize accordingly. Ethernet-based Dedicated Internet Access can provide this feature both costeffectively and reliably. Moreover, multi-site hotel and restaurant chains operating in today’s fastpaced online business environment can upgrade and consolidate services onto a single network that supports voice, data and video traffic alike..

This is a digital forensics questions. How can a hard drive be used for potential evidence as documentary evidence. If it cannot, why? Solution Please follow the data and description : Hard Drives as Evidence : In the stream of forensics department there are many evidences that could be considered and taken in to account for the culprit to be caught. In the same way a hard drive can also be presented as an documentary evidence because it contains various records, data, information and the respective pictures showing the perpetrators behaviour patterns leading to the offence. The hard disk can act as a demonstrative evidence to retrieve the important information that offers for the department and the forensics to prove of what has actually took place over the incident or the case. It can also be used to explain the behaviour patterns of the perpetrator using charts, presentations, slides and so on. Hope this is helpful..
