1- Distinguish the locations and tissues among epidermis, dermis, and hypodermis layers. ? Solution The epidermis is the outermost layer of the skin, below which lies dermis and the hypodermis lies beneath the dermis. Keratinocytes in the epidermis helps to protect the inner layers from the outside environment. The dermis contains blood vessels, lymph vessels, hair follicles, and sweat glands. hypodermis consists of mostly adipose tissue and is the storage site of most body fat. It.

A series RL circuit includes a 9.05-V battery, a resistance of R = 0.pdf
A series RL circuit includes a 9.05-V battery, a resistance of R = 0.755 , and an inductance of L
= 2.97 H. What is the induced emf 1.33 s after the circuit has been closed?
So, basically, I tried solving this equation using an RL circuit formula: I = emf/R(1-e^-t/(L/R))
and used V=IR to solve for the current, for which I plugged it back in to obtain the emf. I got an
answer of about 31, which was wrong. If you could help me on this, it would make my day!
Solution
tau = L/R = 2.97/0.755 = 3.9337
V = V0*e^(-t/tau)
V = 9.05*e^(-1.33/3.9337)
V = 6.453 V.

What is the dangling pointer? Explain with a proper example.
Solution
A dangling pointer is a pointer which nce pointed to some data, but because of memory
deallocation, points to an invalid or null data.
Example:
Suppose we declare and allocate some memory to a pointer:
char *temp = malloc(some_size);
Then we de-allocate the memory allocated to the pointer temp by,
free (temp);
After execution of the above statement, temp becomes a dangling pointer..

What’s Love Got To Do With It?
The Evolution of Human Mating
By Meredith F. Small
Reviewed By Michael S. Kimmel
When Tina Turner first bitterly asked “What’s love got to do with it?” her voice was so drenched
with pain and regret, the listener knew better than to believe her.
Not so Meredith Small. A physical anthropologist whose main research has been on primate
mating behavior, Small joins a coterie of such writers as Robert Ardrey, Desmond Morris and
Lionel Tiger, who have sought to make evolutionary biology the foundation of studies of sexual
behavior.
In “What’s Love Got To Do With It,” Small argues that we’re genetically programmed to
experience sexual pleasure; hard-wired to search for young, attractive mates; driven to copulate
“Way down deep, underneath all the love and lust, underlying the attachment and intimacy, is
DNA pushing us along”
Like those male writers, she claims that our genetic predisposition toward reproductive success is
the driving force of our sex-seeking behavior. And like them, she assumes that sex is a constant,
universal and relatively unchanging experience. But unlike them, Small places no value on
judgments on the strategies that individuals may adopt to achieve that reproductive success.
Women, she argues, are as sexual as men; homosexuality is as “normal” as heterosexuality.
Small exposes many of her colleagues’ conclusions as based more on myth than on evolution.
Take, for example, the familiar canard that men are “naturally” predisposed toward promiscuity,
while women are “naturally” monogamous. Males’ prodigious sperm production, the argument
goes, means that it is in men’s interest to fertilize as many women as possible. But women
produce only one egg at a time, and gestation and child care take an extraordinarily long time,
which means that it is in their interest to mate with only one man for life.
Not only do such arguments assume what they are trying to explain, but their assumptions are
wrong to begin with. Sperm and eggs do not have little personalities, complete with ambitions
and motivations. What’s more, the evidence actually tilts the other way. Female humans are
among the only mammals who conceal estrus; that is, they do not go into “heat” when they are
sexually receptive. They are potentially sexually receptive all through their cycle. What’s more, a
woman has a clitoris, which “exists only to receive and give off sexual pleasure.” What could be
the evolutionary function of that?
Small argues that it is just as likely that women may be designed to maximize their reproductive
chances by promiscuity. If they have sex with a large number of male partners, they can ensure
that their offspring will have a significant number of men who believe that they are the father,
and who will, therefore, protect the baby and provide it with food.
“The ability to move from male to male certainly improves a female’s chance of finding the best
genes for her future offspring,” Small writes.
Males, by contrast, wo.
What is the Surface characterization techniques of Fourier-transform.pdf
What is the Surface characterization techniques of Fourier-transform infrared spectroscopy
(FTIR) and Optical Imaging and Spectroscopy (microscopy, TIRF)
explain what are they measuring, their uniqueness, working principle briefly
Solution
Fourier transform infrared spectroscopy (FTIR) is a powerful analysis tool for characterizing and
identifying organic molecules. It is the spectroscopic technique that is the most widely used for
determining the characteristics of new membranes. In attenuated total reflectance mode, this type
of spectroscopy enables functional groups present over a depth of about 1 m to be identified.
During ATR analysis, the sample is kept in contact with a crystal allowing total internal
reflection. An infrared ray arrives at the crystal where the material under study has been placed.
The internal reflection of the ray in the crystal gives rise to an evanescent wave which, at each
reflection, continues beyond the surface of the crystal and penetrates the sample over about 1 m.
The penetration depth depends on the wavelength, the angle of incidence of the beam on the
crystal, and the nature of the crystal.
Spectra are thus obtained (curves of absorbance vs. wavelength) that have absorption peaks
characteristic of the functions present at the membrane surface.
FTIR-ATR is a sensitive, nondestructive method that can be used qualitatively and
quantitatively. However, it requires prior drying of the membrane sample.
One of the applications of FTIR-ATR is the characterization of modified surfaces. In this case,
the spectra show bands characteristic of the basic membrane with, in most cases, bands
characteristic of the new functional groups related to the modification. FTIR-ATR also enables
the efficiency of membrane cleaning to be assessed .
This method can also be used to analyze the adsorption of macromolecules at the membrane
surface and to check whether the conformation of the adsorbed compounds (e.g., proteins) has
been modified by comparing the spectra of the adsorbed product with those of the same product
in solution . When the deposits are very small, however, it is difficult to determine the presence
of fouling agents; this necessitates the use of elaborate data-processing methods that eliminate
the contributions of the membrane and water from the raw spectra.
UNIQUENESS:
There are three principal advantages for an FT spectrometer compared to a scanning (dispersive)
spectrometer.
TIRF
Total internal reflection fluorescence (TIRF) microscopy (TIRFM) is an elegant optical
technique that provides for the excitation of fluorophores in an extremely thin axial region
(‘optical section’). The method is based on the principle that when excitation light is totally
internally reflected in a transparent solid (e.g., coverglass) at its interface with liquid an
electromagnetic field, called the evanescent wave, is generated in the liquid at the solid-liquid
interface and is the same frequency as the excitation light. Since the inte.

We are removing half the data at each turn so time complexity is O(log n).
We divide it into 2 till we find 1. Thus,

What are the security requirements and challenges of Grid and Cloud .pdf
What are the security requirements and challenges of Grid and Cloud Computing?
Solution
security issues:
A. Policies:
1) Inside Threats: good supervision should be done for having trusted employees .
2) Access Control:Digital signature can be implemented
for access control.
3) System Portability: The problem of vendor lock-in
should be handled .
B. Software Security:
1) Virtualization technology: up to date version of
virtualization product should be installed for the
security reasons.
2) Host Operating System:should be up to date and
secure from hackers
3) Guest Operating System: should be up to date and
secure from hackers
4) Data Encryption:should be done on all the data for
its safety.
C)Physical security:
1) Backup:Either a backup plan should be provided
automatically for each customer, or they can use the
plans provided elsewhere in the cloud.
2) Server Location:It should be at appropriate place. Room should have adequate space and
isolated. A
Cooling System and Fire Suppression System should
be installed there.
3) Firewall: Cloud Computing service providers should
provide a complete firewall solution to their clients.
Challenges:
A)No clear standard:Grid computing
uses various standards, but all grids are
not use same standards. Example all grid
operating system such as Linux, Apache,and My SQL are using WSRF,
WWW, SOAP and XML standards.
B)Distributed computing Vs Grid
computing: Grid computing involves
dynamic virtual organisation, resource
sharing and peer to peer computing. The
Grid intends to make access to
computing power, scientific data
repositories and experimental facilities
as easy as the Web makes access to
information. Same all facilities provide
the grid computing. So it is a challenge
for grid computing.
C)Lack of grid enabled software: The
software, which are enabled the grid
computing are less, It has limited
software on Grid. Much software has
not copyright issues and source code of
licence. It is need for more company
developing grid-enabled version, need
more developers on grid development
and need to develop open source
software.
D)Sharing Resources between Various
types of Services:Grid used for
sharing resource from various sites and
grid hosts. It handles a massive amount
of data as a grid platform. A lot of sites
and multiple servers gathered there it is
so complex infrastructure. It provides
difficulty for hardware resource sharing
within virtual organisation..

The organization of interrupted genes is often conserved between spe.pdf
The organization of interrupted genes is often conserved between species. What does this mean
and what is an example of this conservation (diagram/explain)?
Solution
First we have know about interrupted genes is often conserved between species,the intricate
cellular machinery that converts genetic information into functional protein and RNA molecules
and the many ways in which gene expression is regulated by the cell,we discuss some of the
ways that genes and genomes have evolved over time to produce the vast diversity of modern-
day life forms on our planet uncovering an astonishing wealth of information about the family
relationships among organisms and evolutionary mechanisms,but the great revelation of the past
20 years has been the discovery that the actual nucleotide sequences of many genes are
sufficiently well conserved that homologous genes.
The recognition of sequence homology has become a major tool for inferring gene and protein
function thus it is often possible to predict the function of a gene in humans for which no
biochemical or genetic information is available simply by comparing its sequence to that of an
intensively studied gene in another organism.
Gene sequences are often far more tightly conserved than is overall genome structure as
discussed features of genome organization such as genome size,cells do not have specialized
mechanisms for creating changes in the structures of their genomes evolution depends instead on
accidents and mistakes.
Introns can be detected by the presence of additional regions when genes are compared with their
RNA products by restriction mapping or electron microscopy
The positions of introns are usually conserved when homologous genes are compared between
different organisms but the lengths of the corresponding introns may vary greatly..

Solution
The basic principle of Enrichment is that of selection. Enrichment culture provides favourable
growth conditions for the organism of intrest and unfavourable conditions for the competing
organisms. This technique can be used in many ways. for example, if we want to culture a
thermophile bacteria, incubate the sample at high temperature i.e., at above 55 degrees
centigrade because at that temperature, only the thermophilic bacteria can grow while this
temperature hampers the growth of other bacteria in the sample.
Likewise, enrichment culture may also contains antimicrobial agents to which the selective
organism is resistant hence the required organism\'s growth is facilitated hampering the growth
of other organisms which are not resistant to the antimicrobial agent.
Enrichment culture may also contains pesticides or N2 (used for selective growth of nitrogen
fixing bacteria) depending upon the type of microorganism selected.
Hence the Answer is a lawn of bacteria is prepared and filter discs containing antimicrobial
agents are applied..

Q1) Show what part of SSL that protects against the following attack.pdf
Q1) Show what part of SSL that protects against the following attacks :-
a. Replay Attack: Earlier SSL handshake messages are replayed.
b. Man-in-the-Middle Attack: An attacker interposes during key exchange, acting as the client to
the server and as the server to the client.
c. IP Spoofing: Uses forged IP addresses to fool a host into accepting bogus data.
Q2) Describe the port forwarding operation. Using an example, describe the cases when it is very
useful, and the cases when it is very dangerous.
Solution
The secure socket layer (SSL) is a computer networking protocol that manages server
authentication, client authentication and encrypted communication between servers ant client
.
PROTACTION FROM REPLAY ATTACK-
The SSL itself is protected againsts replay attack using Medium Access Control ( MAC ). By
using MAC secret and the sequence number it ensures the communication integrity.
ssl handshake protocol
PROTECTION AGAINSTS MAN-IN-THE MIDDLE ATACK-
SSL is based on public/ private key cryptography. This basically means that there is a key pair.
The public key is used for encryption and secret key is used for decryption . A certificate is
basically a public key with a label identifying the owner. So when your browser connects to an
https server , the server will answer with its certificate. The browser checks if the certificate is
valid-
1: The owner information needs to match the server name that the user requested.
2: The certificate needs to be signed by a trusted certification authority.
if one of these condition is not met, the user is informed about the problem.
PROTECTION AGAINSTS IP SPOOFING-
An SSL certificate is specific to the particular domain for which it was created regardless of the
IP address of the doimain. So if a malicious entity want to attempt to redirect trafiic for a certain
website to their own malicious site through IP spoofing techniques. The fake site would not have
a SSL certificate that was accurately registerd to the real website.This can be varified through a
browser by viewing the certificate information and if the wrong address is shown, then the user
will know that they are not on the site they think they are on.Secure Socket Layer Architecture

Let’s make it so that we can look up and find a Patient in the “Patients.txt” file. The Patients are
organized by Patients Code. So we should be able to look in the File for Patient “A900”, and it
should give us back all the data about that Patient, like, Patinet Id, etc. So we will need to read
from the “Patients.txt” file and select the Patient Id “A900”. The File is delimited by “:”(colons).
Take a look at the file. use FileInputStream and Buffered reader to read from the file.
Code for testing ‘Select’ that goes in main:
Patient p1 = new Patient();
p1.select(“A900”);
p1.display();
Let’s also make it so that we can add a new Patient to the “Patients.txt” file.use PrintStream and
Buffered writer to write to the file. We should be able to append a new line to the “Patients.txt”
file with all the data for a new Patient, like PatientId,etc.
Code for testing ‘Insert’ that goes in main:
Patient p1 = new Patient();
p1.insert(“A900\",\"1234\",\"Jimmy:Hawkins\",\"Marietta\",\"jhawk@yahoo.com\",\"Cigna\");

dsRNA
Retroviruses have a single stranded RNA genome. Two copies of the sense strand of the genome
are present with the viral particle. When they infect a T cell, the single stranded RNA is
converted into dsDNA copy by the reverse transcriptase. Replication and transcription occur
from this dsDNA intermediate, the provirus, whihc is integrated into the host cell genome by a

Please make sure you write about Republic of Turkey otherwise please.pdf
Please make sure you write about Republic of Turkey otherwise please don\'t waste your and my
time. Thanks!!
Give an example of Republic of Turkey\'s regional economic integration and identify several
potential benefits and several potential drawbacks of regional integration for Republic of Turkey.
Elaborate on the protocols of the regional agreement.
Solution
Turkey’s need for foreign markets in 1980s led the country to strengthen regional cooperation
with trading partners worldwide. Trade ties with Middle East received particular attention under
Ozal. Business people also worked to improve trade ties with North America, East Asia, and
Eastern Europe. Turkey’s increased attention to Middle Eastern markets boosted export of
manufactured goods and construction services.
The Ozal government made a formal application to EC membership. The European Commission
issued an official opinion on the Turkish application but proposed that negotiations should not
commence until 1993. Negotiations thereafter led the EU to vote for Turkey’s inclusion in the
free trade area in 1995. The steady liberalization of the economy and integration begun by
former President Ozal has continued without interruption.
Some observers have postulated that admitting Turkey into EU would have some negative
effects. One that the level of industrialization in Turkey lags behind the European countries, that
the degree of budgetary transfers to lift Turkey to the levels of even the poorest European
countries would place a huge burden on Europe’s resources, and that given entry would mean
permitting labor mobility. They were also sceptical about human rights policies of Turkey.
Despite several setbacks, Turkey has been designated a major emerging market by the main
international financing centers. Most observers have instilled confidence in the economy because
a large proportion of foreign investments has gone into industrialization. It has also been
acknowledged the government’s ability to steer the economy toward the objective of making
Turkey a major regional and international industrial power.

Solution
Please find the answer below.
Lec 10:
1. The nervous system is divided into the central nervous system and peripheral nervous system.
2. The basic function of a neuron is to receive the information and send a signal to other neurons,
muscles, or glands. First, a neuron receives information from the external environment or from
other neurons. Then, the neuron integrates, or processes the information from all of its inputs and
determines whether or not to send an output signal.
3. The dendrites and axon are thin cytoplasmic extensions of the neuron. The dendrites, which
branch out in treelike fashion from the cell body, are specialized to receive signals and transmit
them toward the cell body. The single long axon carries signals away from the cell body.
The cell body (soma) is the enlarged portion of a neuron that most closely resembles other cells.
Nodes of Ranvier are a gap in the myelin sheath of a nerve, between adjacent Schwann cells.
4. Ion channels and direction:
As an action potential travels down the axon, there is a change in polarity across the membrane.
The Na+ and K+ gated ion channels open and close as the membrane reaches the threshold
potential, in response to a signal from another neuron. At the beginning of the action potential,
the Na+ channels open and Na+ moves into the axon, causing depolarization. Repolarization
occurs when the K+ channels open and K+ moves out of the axon. This creates a change in
polarity between the outside of the cell and the inside. The impulse travels down the axon in one
direction only, to the axon terminal where it signals other neurons..

Jim produces and sells $1100 worth of flowers. Jim uses no intermedi.pdf
Jim produces and sells $1100 worth of flowers. Jim uses no intermediate inputs. He pays his
workers $700 in wages, pays $100 in taxes and pays $200 in interest on a loan. What is Jim\'s
contribution to GDP? What are Jim\'s profits?
Solution
by income approach of calculating GDP,
GDP = wages paid to workers + interest
= 700+200 = $900
profit = 1100 - 700 - 100 - 200
= $100.
How will you choose to contribute to the public good over not contri.pdf
How will you choose to contribute to the public good over not contributing, and what factors
must be considered.
Solution
Public goods are goods that everyone (contributors and non-contributors alike) can enjoy, once
they are provided.
Casual observations in economic system highlights that sometimes people choose to contribute
to the public good over not contributing, even when we recognize the pull to free ride on the
contributions of others. This contribution can be in the following forms: effort in work teams,
provision of tangible or intangible public goods, the use of natural resources (the tragedy of the
commons), contributions to charities, tax honesty, buyer-seller relationships, employer-employee
relationships.
The explanatory factors which motivates people to contribute may be efficient coercion,
selective incentives, institutional structure, government trustworthiness, social norms, social
capital, ethical reciprocity, and dispositions.

What are the security requirements and challenges of Grid and Cloud .pdf
What are the security requirements and challenges of Grid and Cloud Computing?
Solution
security issues:
A. Policies:
1) Inside Threats: good supervision should be done for having trusted employees .
2) Access Control:Digital signature can be implemented
for access control.
3) System Portability: The problem of vendor lock-in
should be handled .
B. Software Security:
1) Virtualization technology: up to date version of
virtualization product should be installed for the
security reasons.
2) Host Operating System:should be up to date and
secure from hackers
3) Guest Operating System: should be up to date and
secure from hackers
4) Data Encryption:should be done on all the data for
its safety.
C)Physical security:
1) Backup:Either a backup plan should be provided
automatically for each customer, or they can use the
plans provided elsewhere in the cloud.
2) Server Location:It should be at appropriate place. Room should have adequate space and
isolated. A
Cooling System and Fire Suppression System should
be installed there.
3) Firewall: Cloud Computing service providers should
provide a complete firewall solution to their clients.
Challenges:
A)No clear standard:Grid computing
uses various standards, but all grids are
not use same standards. Example all grid
operating system such as Linux, Apache,and My SQL are using WSRF,
WWW, SOAP and XML standards.
B)Distributed computing Vs Grid
computing: Grid computing involves
dynamic virtual organisation, resource
sharing and peer to peer computing. The
Grid intends to make access to
computing power, scientific data
repositories and experimental facilities
as easy as the Web makes access to
information. Same all facilities provide
the grid computing. So it is a challenge
for grid computing.
C)Lack of grid enabled software: The
software, which are enabled the grid
computing are less, It has limited
software on Grid. Much software has
not copyright issues and source code of
licence. It is need for more company
developing grid-enabled version, need
more developers on grid development
and need to develop open source
software.
D)Sharing Resources between Various
types of Services:Grid used for
sharing resource from various sites and
grid hosts. It handles a massive amount
of data as a grid platform. A lot of sites
and multiple servers gathered there it is
so complex infrastructure. It provides
difficulty for hardware resource sharing
within virtual organisation..

The organization of interrupted genes is often conserved between spe.pdf
The organization of interrupted genes is often conserved between species. What does this mean
and what is an example of this conservation (diagram/explain)?
Solution
First we have know about interrupted genes is often conserved between species,the intricate
cellular machinery that converts genetic information into functional protein and RNA molecules
and the many ways in which gene expression is regulated by the cell,we discuss some of the
ways that genes and genomes have evolved over time to produce the vast diversity of modern-
day life forms on our planet uncovering an astonishing wealth of information about the family
relationships among organisms and evolutionary mechanisms,but the great revelation of the past
20 years has been the discovery that the actual nucleotide sequences of many genes are
sufficiently well conserved that homologous genes.
The recognition of sequence homology has become a major tool for inferring gene and protein
function thus it is often possible to predict the function of a gene in humans for which no
biochemical or genetic information is available simply by comparing its sequence to that of an
intensively studied gene in another organism.
Gene sequences are often far more tightly conserved than is overall genome structure as
discussed features of genome organization such as genome size,cells do not have specialized
mechanisms for creating changes in the structures of their genomes evolution depends instead on
accidents and mistakes.
Introns can be detected by the presence of additional regions when genes are compared with their
RNA products by restriction mapping or electron microscopy
The positions of introns are usually conserved when homologous genes are compared between
different organisms but the lengths of the corresponding introns may vary greatly..

selective pressure A kind of virus that preferentially and exclusively infects bacterial cells A
circular clearing within a lawn of growth; surrounding a disk or colony containing an
antimicrobial
Solution
The basic principle of Enrichment is that of selection. Enrichment culture provides favourable
growth conditions for the organism of intrest and unfavourable conditions for the competing
organisms. This technique can be used in many ways. for example, if we want to culture a
thermophile bacteria, incubate the sample at high temperature i.e., at above 55 degrees
centigrade because at that temperature, only the thermophilic bacteria can grow while this
temperature hampers the growth of other bacteria in the sample.
Likewise, enrichment culture may also contains antimicrobial agents to which the selective
organism is resistant hence the required organism\'s growth is facilitated hampering the growth
of other organisms which are not resistant to the antimicrobial agent.
Enrichment culture may also contains pesticides or N2 (used for selective growth of nitrogen
fixing bacteria) depending upon the type of microorganism selected.
Hence the Answer is a lawn of bacteria is prepared and filter discs containing antimicrobial
agents are applied..

Q1) Show what part of SSL that protects against the following attack.pdf
Q1) Show what part of SSL that protects against the following attacks :-
a. Replay Attack: Earlier SSL handshake messages are replayed.
b. Man-in-the-Middle Attack: An attacker interposes during key exchange, acting as the client to
the server and as the server to the client.
c. IP Spoofing: Uses forged IP addresses to fool a host into accepting bogus data.
Q2) Describe the port forwarding operation. Using an example, describe the cases when it is very
useful, and the cases when it is very dangerous.
Solution
The secure socket layer (SSL) is a computer networking protocol that manages server
authentication, client authentication and encrypted communication between servers ant client
.
PROTACTION FROM REPLAY ATTACK-
The SSL itself is protected againsts replay attack using Medium Access Control ( MAC ). By
using MAC secret and the sequence number it ensures the communication integrity.
ssl handshake protocol
PROTECTION AGAINSTS MAN-IN-THE MIDDLE ATACK-
SSL is based on public/ private key cryptography. This basically means that there is a key pair.
The public key is used for encryption and secret key is used for decryption . A certificate is
basically a public key with a label identifying the owner. So when your browser connects to an
https server , the server will answer with its certificate. The browser checks if the certificate is
valid-
1: The owner information needs to match the server name that the user requested.
2: The certificate needs to be signed by a trusted certification authority.
if one of these condition is not met, the user is informed about the problem.
PROTECTION AGAINSTS IP SPOOFING-
An SSL certificate is specific to the particular domain for which it was created regardless of the
IP address of the doimain. So if a malicious entity want to attempt to redirect trafiic for a certain
website to their own malicious site through IP spoofing techniques. The fake site would not have
a SSL certificate that was accurately registerd to the real website.This can be varified through a
browser by viewing the certificate information and if the wrong address is shown, then the user
will know that they are not on the site they think they are on.Secure Socket Layer Architecture

Let’s make it so that we can look up and find a Patient in the “Patients.txt” file. The Patients are
organized by Patients Code. So we should be able to look in the File for Patient “A900”, and it
should give us back all the data about that Patient, like, Patinet Id, etc. So we will need to read
from the “Patients.txt” file and select the Patient Id “A900”. The File is delimited by “:”(colons).
Take a look at the file. use FileInputStream and Buffered reader to read from the file.
Code for testing ‘Select’ that goes in main:
Patient p1 = new Patient();
p1.select(“A900”);
p1.display();
Let’s also make it so that we can add a new Patient to the “Patients.txt” file.use PrintStream and
Buffered writer to write to the file. We should be able to append a new line to the “Patients.txt”
file with all the data for a new Patient, like PatientId,etc.
Code for testing ‘Insert’ that goes in main:
Patient p1 = new Patient();
p1.insert(“A900\",\"1234\",\"Jimmy:Hawkins\",\"Marietta\",\"jhawk@yahoo.com\",\"Cigna\");

dsRNA
Retroviruses have a single stranded RNA genome. Two copies of the sense strand of the genome
are present with the viral particle. When they infect a T cell, the single stranded RNA is
converted into dsDNA copy by the reverse transcriptase. Replication and transcription occur
from this dsDNA intermediate, the provirus, whihc is integrated into the host cell genome by a

Please make sure you write about Republic of Turkey otherwise please.pdf
Please make sure you write about Republic of Turkey otherwise please don\'t waste your and my
time. Thanks!!
Give an example of Republic of Turkey\'s regional economic integration and identify several
potential benefits and several potential drawbacks of regional integration for Republic of Turkey.
Elaborate on the protocols of the regional agreement.
Solution
Turkey’s need for foreign markets in 1980s led the country to strengthen regional cooperation
with trading partners worldwide. Trade ties with Middle East received particular attention under
Ozal. Business people also worked to improve trade ties with North America, East Asia, and
Eastern Europe. Turkey’s increased attention to Middle Eastern markets boosted export of
manufactured goods and construction services.
The Ozal government made a formal application to EC membership. The European Commission
issued an official opinion on the Turkish application but proposed that negotiations should not
commence until 1993. Negotiations thereafter led the EU to vote for Turkey’s inclusion in the
free trade area in 1995. The steady liberalization of the economy and integration begun by
former President Ozal has continued without interruption.
Some observers have postulated that admitting Turkey into EU would have some negative
effects. One that the level of industrialization in Turkey lags behind the European countries, that
the degree of budgetary transfers to lift Turkey to the levels of even the poorest European
countries would place a huge burden on Europe’s resources, and that given entry would mean
permitting labor mobility. They were also sceptical about human rights policies of Turkey.
Despite several setbacks, Turkey has been designated a major emerging market by the main
international financing centers. Most observers have instilled confidence in the economy because
a large proportion of foreign investments has gone into industrialization. It has also been
acknowledged the government’s ability to steer the economy toward the objective of making
Turkey a major regional and international industrial power.

Solution
Please find the answer below.
Lec 10:
1. The nervous system is divided into the central nervous system and peripheral nervous system.
2. The basic function of a neuron is to receive the information and send a signal to other neurons,
muscles, or glands. First, a neuron receives information from the external environment or from
other neurons. Then, the neuron integrates, or processes the information from all of its inputs and
determines whether or not to send an output signal.
3. The dendrites and axon are thin cytoplasmic extensions of the neuron. The dendrites, which
branch out in treelike fashion from the cell body, are specialized to receive signals and transmit
them toward the cell body. The single long axon carries signals away from the cell body.
The cell body (soma) is the enlarged portion of a neuron that most closely resembles other cells.
Nodes of Ranvier are a gap in the myelin sheath of a nerve, between adjacent Schwann cells.
4. Ion channels and direction:
As an action potential travels down the axon, there is a change in polarity across the membrane.
The Na+ and K+ gated ion channels open and close as the membrane reaches the threshold
potential, in response to a signal from another neuron. At the beginning of the action potential,
the Na+ channels open and Na+ moves into the axon, causing depolarization. Repolarization
occurs when the K+ channels open and K+ moves out of the axon. This creates a change in
polarity between the outside of the cell and the inside. The impulse travels down the axon in one
direction only, to the axon terminal where it signals other neurons..

Jim produces and sells $1100 worth of flowers. Jim uses no intermedi.pdf
Jim produces and sells $1100 worth of flowers. Jim uses no intermediate inputs. He pays his
workers $700 in wages, pays $100 in taxes and pays $200 in interest on a loan. What is Jim\'s
contribution to GDP? What are Jim\'s profits?
Solution
by income approach of calculating GDP,
GDP = wages paid to workers + interest
= 700+200 = $900
profit = 1100 - 700 - 100 - 200
= $100.
How will you choose to contribute to the public good over not contri.pdf
How will you choose to contribute to the public good over not contributing, and what factors
must be considered.
Solution
Public goods are goods that everyone (contributors and non-contributors alike) can enjoy, once
they are provided.
Casual observations in economic system highlights that sometimes people choose to contribute
to the public good over not contributing, even when we recognize the pull to free ride on the
contributions of others. This contribution can be in the following forms: effort in work teams,
provision of tangible or intangible public goods, the use of natural resources (the tragedy of the
commons), contributions to charities, tax honesty, buyer-seller relationships, employer-employee
relationships.
The explanatory factors which motivates people to contribute may be efficient coercion,
selective incentives, institutional structure, government trustworthiness, social norms, social
capital, ethical reciprocity, and dispositions.

The Roman Empire A Historical Colossus.pdf
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

- 1. 1- Distinguish the locations and tissues among epidermis, dermis, and hypodermis layers. ? Solution The epidermis is the outermost layer of the skin, below which lies dermis and the hypodermis lies beneath the dermis. Keratinocytes in the epidermis helps to protect the inner layers from the outside environment. The dermis contains blood vessels, lymph vessels, hair follicles, and sweat glands. hypodermis consists of mostly adipose tissue and is the storage site of most body fat. It
