You heated the samples containing your cheek cells. Think carefully about where this DNA was packaged in your cells, and what high temperatures usually do to enzyme structure and function. (Hint: Lysosomes contain enzymes known as DNAses!) What functions do you think these high temperature incubations served in your DNA extractions? Solution The DNA is present in the nucleus of the cell, i.e. enclosed in the nuclear membrane. At high temperatures, the membrane of organelles is break-down. The breakup of lysosomal membrane result in leakage of lysosomal enzymes, which break down the other organelles. But at higher temperatures, these enzymes become functionally inactive as they become denatured upon exposure to higher temperatures. So, the DNAases cannot break down DNA, and it can be extracted out..

• Sexual orientation is often framed on a binary-gay OR straight; homosexual OR heterosexual. Why can sexual orientation be thought of as a continuum? Solution Sexual orientation is a psychological or physiological understanding of sexuality in humans.It is thought of as a continuum as it undergoes a gradual transition from heterosexuality to homosexuality.There could exist sexual attraction towards opposite sex (heterosexual) exclusively at one end or attraction towards same sex (homosexual) exclusively at the other end..

You will need to develop a system that can track employee information for two Organizations (such as Google and Microsoft). The Employee information you must track is as follows: Name Gender Job Title Organization they work for Birthday As for the Organization that the Employee works for, you must also track this information: Organization Name Number of Employees The system must be able to properly compare any two employees against each other to determine if they are the same Employee. This means that if you compared two Employees with the same Name, Gender, Birthday and Organization, the system should think that they are equal to one another. If any of these properties are different, then the two Employees are not the same Employee. The same rules apply to comparing Organizations to one another. Organizations with the same Organization name are to be thought of as equal, different names means different organizations. Use the charts on the next page to create your classes. Employee private String name; private String gender; private String jobTitle; private Organization organization; private String birthDate; Employee(String theName, String theGender, String title, Organization org, String theBirthDate) <> String getName() String getGender() String getJobTitle() Organization getOrganization() String getBirthDate() String toString() boolean equals(Employee other) <> void changeJobTitle (String newTitle) void changeName(String newName) void changeOrganization(Organization org) Organization private String organizationName; private int numEmployees; Organization(String name, int employees) <> String getOrganizationName() int getNumEmployees() String toString() boolean equals(Organization other) <> void changeOrganizationName(String newName) *****NOTE: All constructors and methods should be public. ***** *Note: There is a zip file listed that has a starts for each of the classes that are required.

write at least 3 virulence factors for staph, strep A, strep B, strep D, pneumococcus, Nisseria Meningo, nisseria gonorrhoeae, haemophilus write at least 3 virulence factors for staph, strep A, strep B, strep D, pneumococcus, Nisseria Meningo, nisseria gonorrhoeae, haemophilus write at least 3 virulence factors for staph, strep A, strep B, strep D, pneumococcus, Nisseria Meningo, nisseria gonorrhoeae, haemophilus Solution Staphylococcus expresses many potential virulence factors. They are : (1) surface proteins that induces colonization of host tissues (2) invasins that helps in bacterial spread in tissues (leukocidin, kinases, hyaluronidase); (3) surface factors that resist phagocytic engulfment (capsule, Protein A); (4) biochemical properties that increase their chance of survival in phagocytes (carotenoids, catalase production); (5) immunological disguises like Protein A, coagulase; (6) membrane-damaging toxins that lyse eucaryotic cell membranes (hemolysins,leukotoxin, leukocidin; (7) exotoxins that destroy host tissues or provoke symptoms of disease (SEA-G, TSST, ET); (8) inherent and acquired resistance to antimicrobial agents Streptococcus pyogenes (Group A streptococcus) expresses the following virulence factors : (1) M protein, fibronectin-binding protein (Protein F) and lipoteichoic acid that help in adherence (2) hyaluronic acid capsule which acts as an immunological disguise and inhibits phagocytosis; (3) invasins such as streptokinase, streptodornase (DNase B), hyaluronidase, and streptolysins; (4) exotoxins, such as pyrogenic (erythrogenic) toxin which forms the rash of scarlet fever and systemic toxic shock syndrome. Streptococcus agalactiae ( Group B streptococcus ) expresses the following virulence factors : (1) capsular polysaccharides, which confer serotype specificity to GBS (2) C proteins and other related surface proteins (3) Pilins function as adhesins, promote CNS entry, and enhance biofilm formation (4) a pore-forming toxin, -hemolysin, that today is considered identical to the GBS pigment Group D Streptococci have been reclassified and placed in the genus Enterococcus. The virulence factors are : (i) adherence to host tissues facilitated by aggregation substance, surface carbohydrates, or fibronectin-binding moieties (ii) invasion and abscess formation, (iii) factors potentially relevant to modulation of host inflammatory responses, (iv) potentially toxic secreted products (v) Extracellular toxins such as cytolysin can induce tissue damage The pneumococcus virulence factors are : (1) the choline-binding proteins; (2) pneumococcal surface proteins A and C (PspA and PspC); (3) the LPXTG-anchored neuraminidase proteins; hyaluronate lyase (Hyl); (4) pneumococcal adhesion and virulence A (PavA); (5) enolase (Eno); pneumolysin; autolysin A (LytA) The virulence factors of Neisseria meningitidis are : (1) Capsules whose presence provide resistance against antibody, complement-mediated, or phagocytic destruction by the host i.

Why have rodents been spectacularly successful? What role do you think human activity has played in their success over the last 500 years? Please answer the question fully and correctly. Solution because they are cosmopolitan in distribution, exploit a broad spectrum of food and out number all other mammals. When humans ceased to be hunter gatherers and instead became farmers, their lives and those of rats became intimately connected. Humans learned to grow and store grain, and rats learned it was easier to feed off these stores than to fend for themselves. They also discovered that human dwellings provided excellent shelter from the elements..

What tissue type has polarity and is avascular What tissue type has polarity and is avascular Solution The epithelial tissue do not receive vascular supply, so they are avascular. It is polar because it contains apical, lateral and basal membrane domains. The epithelial tissues form the sheet like outer covering of the body surfaces and provide protection to the organs. One surface of this epithelial tissue is not bound to anything and produces glandular secretions, also involved in absorption process. The characteristics of the epithelial tissues include the following: 1). Cells undergo frequent cell division 2). Lack of blood vessels 3). Cells are tightly packed by cell junctions..

What is meant by modular software and why is it important? How can the modularity of a program code be quantifiably measured? Solution 1) What is ment by modular software and why is it important? Answer:- How important is modularization of software projects: Modularization is obviously important in software projects, but I want to know people\'s opinions on how important and for what reasons it is important. I\'ve obviously got my own ideas since I\'m asking this, but think of it like a \"common brainstorm\" of the reasons one should modularize one\'s software projects.. Techopedia explains Modular Programming: 1) Modules in modular programming enforce logical boundaries between components and improve maintainability. They are incorporated through interfaces. They are designed in such a way as to minimize dependencies between different modules. Teams can develop modules separately and do not require knowledge of all modules in the system. 2) Each and every modular application has a version number associated with it. This provides developers flexibility in module maintenance. If any changes have to be applied to a module, only the affected subroutines have to be changed. This makes the program easier to read and understand. 3) Modular programming has a main module and many auxiliary modules. The main module is compiled as an executable (EXE), which calls the auxiliary module functions. 2) How can the modularity of a program code be quantifiably measured? Answer:- A Software Metric is a standard of measure of a degree to which a software system or process possesses some property. Even if a metric is not a measurement (metrics are functions, while measurements are the numbers obtained by the application of metrics), often the two terms are used as synonymous. A Software development goal is obtaining objective, reproducible and quantifiable measurements, which may have numerous valuable applications in schedule and budget planning, cost estimation, quality assurance testing, software debugging, software performance optimization, and optimal personnel task assignments..

What are the two major steps in biological classification? What did Linnaeus contribute to taxonomy? are scientific names derived? want to identify the various Solution Answers: 1. Two major steps in biological classification are: a) Defining and describing organisms b) Arranging organisms into a logical classification scheme 2. The binomial nomenclature system was introduced by Carolus Linnaeus. It is used to assign each organism a two part scientific name - genus and species. 3. Scientific names are derived following the universal rules of nomenclature: a) These are in Latin and written in italics. b) The first word represents the genus while the second word is the species epithet c) The first word (genus) is written in capital letter while second word (species) is written in small letter. d) If hand written, they are separately underlined, or printed in italics to denote their Latin origin..

Tissue transplant rejection is primarily a type I reaction. type II reaction. type III reaction. type IV reaction. type V reaction. Solution Organ transplantation is the replacement of a host\'s dysfunctional tissue with a healthy tissue from another organism (host). Since the transplanted organ is from another (foreign) organism, the host\'s immune system reacts to the foreign antigens. This immunological response is a hypersensitivity response called Transplant Rejection. During a Tissue Transplant, the transplant rejection is a T-Cell mediated response against foreign Major Histocompatibility Complex in the donated organ. The Major Histocompatibility Complex are a group of genes that code for proteins found on the surfaces of the donated tissue that helps the immune system to recognize the foreign substances. It usualy takes around weeks to months. Therefore, a tissue transplant rejection is a Type IV hypersensitivity reaction..

The members of the UN peace committee, must choose, from among themselves, a presiding officer of their committee. For each member x, let f(x) designate that member\'s choice for officer. If no two members vote alike, what is the range of f? Solution Since each member can vote only for one person and no two members vote alike the mapping f: x to f(x) is one to one and onto. Hence f is a bijective function So order of x = order of f(x) Or Range of f = No of members of the UN Peace committee.

NetWork Design Question 1a.) In writing a letter to a Friend, what do you hace to do to get the letter to your friend. List all the steps and ways. 1b.) Relate the stages of letter transaction to the layers of the internet. Solution In writing a letter to a Friend, the following 5 steps do you face to get the letter to your friend. 1) Application layer: TCP/IP: A user retrieves a Web page from a server in somewhere by typing a URL into a browser and clicking the enter key. The server receives the request, finds the page on its hard drive and sends it back to the user. Neither the user nor the client or server software is aware of the way the messages were delivered. There are many application layer protocols. 2) Transport layer: TCP/IP: Transport layer software establishes a connection between a client and server then monitors that connection for errors. It also slows transmission if it gets too fast to handle at the other end. Transport layer software is not concerned with how the data is actually moved from one point to the other that is the responsibility of lower level software. There are two transport layer protocols TCP (reliable) and UDP (unreliable, but fast). If TCP tries repeatedly and errors persist, it informs its \"boss,\" the application program. 3) Internet layer: TCP/IP:Internet layer programs move data between networks. IP is the internet layer protocol. IP software ignores the data, and it does the same thing with a packet whether it comes from the friend or your mother. Once the data gets to its destination local area network (LAN), it is handed over to data link layer software or firmware for delivery to the proper computer. 4) Data link layer: TCP/IP:Data Link layer programs move (incoming and outgoing) data within LANs. Ethernet is the most common data link protocol. A data link program is not concerned with how outgoing data will be handled once it leaves the LAN or how incoming data got there. That is the responsibility of the internet layer software. 5) Physical layer: TCP/IP:Physical layer protocols specify the means of representing ones and zeros (bits). The method of transmitting them between two points using wire, radio, fiber, etc. is also specified. There are many ways to make ones and zeros and many ways to transmit them so there are many physical layer protocols..

My question is pretty simple, I just want to know how to call my operator== function in Stack.cpp using a list function. Here is what I meant. This is my Stack.h file: class Stack { public: /**constructors and destructors*/ Stack(); Stack(const Stack &S); ~Stack(); void pop(); void push(int data); bool operator==(const Stack &S); [ .......] private: List stack; }; Here is my List.h file: template class List { private: struct Node { listitem data; Node* next; Node* previous; Node(listitem data) : next(NULL), previous(NULL), data(data) { } }; typedef struct Node* NodePtr; NodePtr start; NodePtr end; NodePtr cursor; int length; public: ........ bool operator==(const List &list); [.......] } [........] template bool List::operator==(const List& list) { if (length != list.length) return false; NodePtr temp1 = start; NodePtr temp2 = list.start; while (temp1 != NULL) { if (temp1->data != temp2->data) return false; temp1 = temp1->next; temp2 = temp2->next; } return true; } [......] So I already define my functions in List.h and I only need to call my function from List again in my Stack.cpp file. For example from my Stack.cpp: Stack::Stack(const Stack &S) : stack(S.stack) { } void Stack::pop() { stack.remove_start(); } [......] And I don\'t know how to call my operator== function in Stack.cpp from the List.h like the way above. This is what my guess so far but did not work: bool Stack::operator==(const Stack &S) { stack.operator==(S.stack); } Thank you Solution When we wish to make a comparison, such as in an if statement, we use the double equals sign (==). 1)bool operator==(const Stack &S); [ .......] It means whatever the boolean operator it should be belongs to stack or equal to. 2) bool operator==(const List &list); Likewise link list also compare with the constructor link list. and constructor need not to call explicitly. it will call itself when program called first..

Irreducible polynomials over a field F play a similar, in a certain sense, role in F[x] to the role the prime numbers play for Z. Using your favorite proof of the existence of an infinite number of primes as inspiration, please prove that there are infinitely many irreducible polynomials over a field F. Solution if there were finite such polynomials.... p1.p2.p3.........pn then p1 * p2 * p3 * ......pn +1 (multiplicative unity) is a polynomial which is either irreducible or can be written as a product of irreducible polynomials. It cannot be irreducible since it is different from the set of irreducibles. Also it cannot be divisible by any irreducible . Say it does pi divides this new polynomial fr some i , then pi divides p1*p2*......pn + 1 and also pi is one of p1,p2....pn so divides p1*p2*....pn hence it divides 1 contradiction.
