• Sexual orientation is often framed on a binary-gay OR straight; ho.pdf
• 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 informatio.pdf
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.

You heated the samples containing your cheek cells. Think carefully .pdf
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..

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.

What tissue type has polarity and is avascular What tissue.pdf
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 t.pdf
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..

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 atype I reaction.type I.pdf
Tissue transplant rejection occurs when the host immune system reacts to antigens in the transplanted organ from a foreign organism. This is a type IV hypersensitivity reaction where T-cells mediate an immune response against the major histocompatibility complex proteins on the surface of donated tissue that help the immune system identify foreign substances. Tissue transplant rejection can take weeks to months to occur as an immune response against the transplanted organ.
The members of the UN peace committee, must choose, from among thems.pdf
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 ope.pdf
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 .pdf
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.

intermediate calculations.) Choose Numerator: | Choose Denominator: | = Current Ratio Current
ratio 2015 to 1
Solution
Answer to Part 1.
Current Ratio = Current Assets / Current Liabilities
Current Assets = Cash + Short Term Investments + Accounts Receivable, net + Notes
Receivable (Trade) + Merchandise Inventory + Prepaid Expenses
Current Assets = $16,000 + $9,200 + $32,200 + $5,000 + $38,150 + $2,800
Current Assets = $103,350
Current Liabilities = Accounts Payable + Accrued Wages Payable + Income Taxes Payable
Current Liabilities = $17,500 + $4,800 + $4,700
Current Liabilities = $27,000
Current Ratio = 103,350 / 27,000
Current Ratio = 3.83 to 1
Answer to Part 2.
Acid-Test Ratio = Quick Assets / Current Liabilities
Quick Assets = Current Assets – Merchandise Inventory – Prepaid Expenses
Quick Assets = $103,350 - $38,150 - $2,800
Quick Assets = $62,400
Acid-Test Ratio = 62,400 /27,000
Acid-Test Ratio = 2.31 to 1
Answer to Part 3.
Days Collected Sales = Current Receivable / Net Sales * 365
Current Receivable = $32,200 + $5,000 = $37,200
Days Collected Sales = 37,200 / 453,600 * 100
Days Collected Sales = 29.93 days
Answer to Part 4.
Inventory Turnover Ratio = Cost of goods sold / Average Inventory
Average Inventory = (38,150 + 53,900) / 2

explain why these three properties of water are importantmelting .pdf
explain why these three properties of water are important?
melting and freezing
cohesive and adhesive
An excellent solvent
Solution
Water melting and freezing properties are important because these properties are main colligative
properties useful to prepare polar biological & pharmaceutical products suitable to the internal
human body environment
The cohesive forces (cohesion) & adhesive forces of water molecules enable to acquire elastic
tendency with considerable surface area promote solubility. This tendency is referred as surface
tension. Surface tension of any fluid decreases with increasing temperature. This is due to
existence of cohesive intermolecular forces between molecules of the fluid is reduced and it is
based on the surrounding environment with adhesive intermolecular forces & viscosity of the
fluid, molecular thermal activity at the liquid interface
For example, water is a universal solvent and it has both polar because it has both positive charge
(H+ or H3O+) and negative charge (OH-). This polarity enables water to make substances to
dissolve in it as charged species. On the other hand, water molecules possess a higher attractive
power to each other so that these forces are referred as cohesive forces responsible for “surface
tension” phenomenon” and these attractions are predominantly due to hydrogen bonding. For
instance, 2 to 3 drops of water between the cover slip is imparted adhesive forces (another
example is capillary rise due to forces between glass and water in capillary tube) between the
two glass cover slips result in adhesion instead of cohesion that potentially differentiate
intermolecular forces between two different substances namely water and silicon. These
intermolecular forces render glass surface as hydrophilic. These intermolecular forces are
decreased as the temperature increases due to increase in molecular thermal activity of the fluid
molecules ate the interface of water molecules.
An excellent solvent
Water is a universal polar solvent and it has hydrogen bonding associated with highest heat
capacity and is referred as “specific heat capacity”. This specific heat is predominantly due to
intermolecular and intermolecular hydrogen bonding. In nature on land when heat is absorbed
result in breaking of hydrogen bonds specifically followed by production of heat. Normally
ocean water cool little bit slower when compared to the land water because of more heat
capacity. This sterile solvent has ability to dissolve a majority of biological products to prepare
pharmaceutical products finally used as diluents in saline, injectables etc.
Water properties and the biological importance of water:
1). Due of the presence of hydrogen bonds and strong intermolecular forces, water has high
specific heat index. Specific heat capacity of water is defined as; the amount of heat (energy in
joules) required for raise of temperature of water per unit mass by 10C.
Our body temperature is maintained higher than the surroundin.
Drosophila melanogaster has one pair of sex chromosomes (XX or XY) a.pdf
Drosophila melanogaster has one pair of sex chromosomes (XX or XY) and three pairs of
autosomes, referred to as chromosomes II, III, and IV. A genetics student discovered a male fly
with very short (sh) legs. Using this male, the student was able to establish a pure breeding stock
of this mutant and found that it was recessive. She then incorporated the mutant into a stock
containing the recessive gene black (b, body color located on chromosome II) and the recessive
gene pink (p, eye color located on chromosome III). A female from the homozygous black, pink,
short stock was then mated to a wild-type male. The F1 males of this cross were all wild type and
were then backcrossed to the homozygous b, p, sh females. The F2 results appeared as shown in
the following table. No other phenotypes were observed.
Based on these results, the student was able to assign short to a linkage group (a chromosome).
Which one was it?
a. X chromosome

What tissue type has polarity and is avascular What tissue.pdf
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 t.pdf
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..

Tissue transplant rejection is primarily atype I reaction.type I.pdf
Tissue transplant rejection occurs when the host immune system reacts to antigens in the transplanted organ from a foreign organism. This is a type IV hypersensitivity reaction where T-cells mediate an immune response against the major histocompatibility complex proteins on the surface of donated tissue that help the immune system identify foreign substances. Tissue transplant rejection can take weeks to months to occur as an immune response against the transplanted organ.
The members of the UN peace committee, must choose, from among thems.pdf
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 Question1a.) In writing a letter to a Friend, what .pdf
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 ope.pdf
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..

explain why these three properties of water are importantmelting .pdf
explain why these three properties of water are important?
melting and freezing
cohesive and adhesive
An excellent solvent
Solution
Water melting and freezing properties are important because these properties are main colligative
properties useful to prepare polar biological & pharmaceutical products suitable to the internal
human body environment
The cohesive forces (cohesion) & adhesive forces of water molecules enable to acquire elastic
tendency with considerable surface area promote solubility. This tendency is referred as surface
tension. Surface tension of any fluid decreases with increasing temperature. This is due to
existence of cohesive intermolecular forces between molecules of the fluid is reduced and it is
based on the surrounding environment with adhesive intermolecular forces & viscosity of the
fluid, molecular thermal activity at the liquid interface
For example, water is a universal solvent and it has both polar because it has both positive charge
(H+ or H3O+) and negative charge (OH-). This polarity enables water to make substances to
dissolve in it as charged species. On the other hand, water molecules possess a higher attractive
power to each other so that these forces are referred as cohesive forces responsible for “surface
tension” phenomenon” and these attractions are predominantly due to hydrogen bonding. For
instance, 2 to 3 drops of water between the cover slip is imparted adhesive forces (another
example is capillary rise due to forces between glass and water in capillary tube) between the
two glass cover slips result in adhesion instead of cohesion that potentially differentiate
intermolecular forces between two different substances namely water and silicon. These
intermolecular forces render glass surface as hydrophilic. These intermolecular forces are
decreased as the temperature increases due to increase in molecular thermal activity of the fluid
molecules ate the interface of water molecules.
An excellent solvent
Water is a universal polar solvent and it has hydrogen bonding associated with highest heat
capacity and is referred as “specific heat capacity”. This specific heat is predominantly due to
intermolecular and intermolecular hydrogen bonding. In nature on land when heat is absorbed
result in breaking of hydrogen bonds specifically followed by production of heat. Normally
ocean water cool little bit slower when compared to the land water because of more heat
capacity. This sterile solvent has ability to dissolve a majority of biological products to prepare
pharmaceutical products finally used as diluents in saline, injectables etc.
Water properties and the biological importance of water:
1). Due of the presence of hydrogen bonds and strong intermolecular forces, water has high
specific heat index. Specific heat capacity of water is defined as; the amount of heat (energy in
joules) required for raise of temperature of water per unit mass by 10C.
Our body temperature is maintained higher than the surroundin.
Drosophila melanogaster has one pair of sex chromosomes (XX or XY) a.pdf
Drosophila melanogaster has one pair of sex chromosomes (XX or XY) and three pairs of
autosomes, referred to as chromosomes II, III, and IV. A genetics student discovered a male fly
with very short (sh) legs. Using this male, the student was able to establish a pure breeding stock
of this mutant and found that it was recessive. She then incorporated the mutant into a stock
containing the recessive gene black (b, body color located on chromosome II) and the recessive
gene pink (p, eye color located on chromosome III). A female from the homozygous black, pink,
short stock was then mated to a wild-type male. The F1 males of this cross were all wild type and
were then backcrossed to the homozygous b, p, sh females. The F2 results appeared as shown in
the following table. No other phenotypes were observed.
Based on these results, the student was able to assign short to a linkage group (a chromosome).
Which one was it?
a. X chromosome
b. chromosome II
c. chromosome III
d. chromosome IV

How to Make a Field Mandatory in Odoo 17
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.
LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
