why is the idea of a standard network protocol such as the OSI refer.pdf
why is the idea of a standard network protocol such as the OSI reference model important ? what
are the advantages and disadvantages of developing a single standard protocol ?
Solution
The idea of standard network protocol such as the OSI reference model is important as OSI
reference model and TCP/IP are the backbone for today\'s computer systems and architecture. It
allows communication between local area networks. Network protocols such as TCP/IP enable
client server computing and assists in information sharing across the world. It has made the
world a global village by providing an information super highway and is as important for
business and commerce as roads, railways and airlines. Standard protocol allows different
departments in the companies to share information and resources.
Advantages of OSI reference model:
Advantages of single standard protocol:
Open standards are industry-wide protocol definitions that are not tied with a specific
manufacturer company. With open standard protocols, we can use equipment from any vendor to
build our network. As long as the equipment implements the standard protocols, it should be able
to coexist on the same network. With open standard protocols, networks can consist of many
different computing platforms running entirely different software.
Protocols are implemented on a network in several ways. Some are integrated into the operating
system. Others are device drivers, such as the driver for a particular network interface adapter
supplied by its manufacturer.
Disadvantages of developing a single standard protocol:
1. If there are problems in standard protocols, all the systems implementing them will be
affected.
2. All companies and manufactures will need to follow the standards and it will get harder to
innovate and create new standards which is orthogonal to the current standard..
Which of the following potential problems need not be considered whe.pdf
Which of the following potential problems need not be considered when eliminating cases with
missing values on one or more variables:
a. Many cases may be lost
b. The correlation between the predictor and the criterion variables may be inflated.
c. The eliminated cases may be systematically different from the retained cases.
d. none of the above--all need to be considered.
Solution
Answer option D
Analysis of covariance (ANCOVA) is a general linear model which blends ANOVA and
regression. ANCOVA evaluates whether population means of a dependent variable (DV) are
equal across levels of a categorical independent variable (IV) often called a treatment, while
statistically controlling for the effects of other continuous variables that are not of primary
interest, known as covariates (CV) or nuisance variables. Mathematically, ANCOVA
decomposes the variance in the DV into variance explained by the CV(s), variance explained by
the categorical IV, and residual variance. Intuitively, ANCOVA can be thought of as \'adjusting\'
the DV by the group means of the CV(s).

4. Explain two-phase locking.
5. Explain the meaning of the expression of ACID transaction.
Solution
1. What is the purpose of database administration?
Data administration is the concept of managing people and their rights on how to access the data
and to which level of granularity is the different people/designations are allowed to access the
data base. Its just authorizing and de-authorizing people on how to access the data.
2. Purpose of concurrency control?
Concurrency control is allowing more than one transaction to access the object in a safe and
secure way such that the database is consistent at the end of multiple transactions. If concurrency
control not applied properly, either the transactions should be performed serially, or the
concurrent transactions may make the database inconsistent.
3. Give an different example of the lost update problem in Lecture slide (Chapter 6-15)
Lost update is the concept of one update done by a transaction is lost, just because the data is
read by other transaction before the update, and is written after the update.
Consider a scenario:
T1: Read A (Assume A = 50)
T2: Read A (Assume A = 50)
T2: Update A (Assume A is increased by 10)
T2: Write A (Now A = 60)
T1: Update A (Assume A is decreased by 10 )
T1: Write A (Now A = 40)
Here the update done by Transaction T2 is lost..

What factors do you think make them excellent project reports write.pdf
What factors do you think make them excellent project reports? write in your own words
Solution
1) Structure - A good report has a proper style and structure. Most businesses prefer the top-
down approach that entails stating the main point or the gist of the point first and then
reinforcing or substantiating the point made.
2) Substance - The report needs to cover the details of the project comprehensively, including all
the big risks and issues that affect the project and solutions for the same.
3) Table of Contents - Large reports, usually more than four pages\' length or containing many
subsections, need to include a table of contents. Incorporation of a table of contents provides a
“top down” gist of the report, allowing the reader to orient himself or read selectively from the
report.
4) Content Heavy Table - Content heavy titles support the “top-down” approach with the title
being the main point and the text that follows the explanation of the point. The best headings
makes the text that follows superfluous.
5) Language and Style - A critical aspect of good project report writing is the use of simple and
easy-to-understand language free from spelling, grammar, and punctuation mistakes. Even minor
spelling and punctuation mistakes can change the entire meaning of sentences and highlight the
project promoters in poor light.
6) Lists, Tables, Figures, and Graphs - Such items highlight key points of emphasis, remove
clutter, and make the report structure easy to read and visually appealing.
Bulleted lists find use to highlight to-do items or specific actions. Figures, graphs, and tables
make for powerful tools to present ideas, make comparisons, or summarize points in a way that
captures and retains interest. Including all such information in descriptive sentences make the
project report too lengthy and cumbersome
7) Appendices - Lengthy project reports require an appendix to place technical details,
background material such as experts from previous studies, lists of supporting programs, raw
data, derivative and analytical expressions, and similar material. Inclusion of such items along
with the main text interrupts the flow nd makes it difficult for the reader who wants to make a
quick initial reading and go into the details at a later stage.
8) References and Citations
A references section becomes mandatory if the report contains results from books or articles. The
best practice is to cite sources in the main text, such as (Harvey, 1999), and provide the full
citation in the references section. Adherence to standard style guidelines such as the APA Style,
MLA Style, Chicago Style, or Harvard Style lends additional credibility to the project report.
9) Proofreading - Pople ignore is proofreading the project report before submission. This is a
mistake! Proofreading can capture inadvertent errors that are simple to correct but costly if not
caught.
10) Appearance - Another factor that many people ignore is ensuring the tidiness and appearan.

What aspects of today\'s information economy have influenced the importance of building
partnerships?
Solution
A revolution in information and communications technology is transforming the way we live
and work. Information Communication Technoloy is becoming the largest distribution platform
of providing public and private services to millions of people in rural and poor areas. It is
changing the way we deliver education and business services, design buildings and cities, and
manufacture engines and cars. Market information, financial services, education and health
services had largely been unavailable in those areas in the past due to lack of connectivity of any
kind. Increases productivity and makes the market work more efficiently reaching population
with low levels of income and literacy. A recognisable new dynamic force – the information
economy – has emerged, and is transforming every other sector. The principles of business
strategy are being transformed from focusing on physical assets and economies of scale to the
drivers of success which reside in connectivity and intangibles. Businesses need to develop and
manage complex ecologies or organizations around themselves so as to succeed. Barriers
between companies, which used to be solid and absolute, are now permeable. Through virtual
integration, the walls between enterprises crumble. Cyber security underpins the information
economy. Without it businesses and consumers would not have the trust and confidence to use
the internet and other digital technologies. People and businesses expect the right information to
be available, all the time, and anywhere. Through trends such as cloud computing, software
services and data are hosted away from users but are accessible on demand, any place or time.
This week, we are going to work together as a class to assist the Lon.pdf
This week, we are going to work together as a class to assist the Lone Star Center for Disease
Control. They have identified a closed population of 10, 000 individuals, where a particularly
nasty strain of flu virus has started to spread. What we know about this particular virus: It
spreads at a rate that is jointly proportional to both the number of infected individuals and then
number of uninfected individuals. When 1, 000 individuals are infected, the rate at which
individuals are becoming infected is 500 individuals per day. There are currently 200 individuals
infected. The LSCDC has determined that it is critical for relief efforts that they know how long
it will take, based upon available information, for 90% of the population to become infected with
the virus. You are not required to solve this entire problem on your own. Post at least the
equivalent of 50 words that contributes to us solving this together throughout the course of the
week.

Take a position on this statement The media represent realistic ima.pdf
The document discusses whether media represents realistic images of Arabs. It argues that media does not, citing a survey that found nearly 50% of adults believe there is persistent negative media bias against Muslims and Arabs in media. As evidence, it notes that in films, the villain is often Arab or Muslim, while the hero is non-Arab. This negative portrayal increases when a group is seen as a security threat. Hispanics have also faced long-term negative bias in media related to immigration debates.
Relate selected early morphological developments in the ancestors of.pdf
Relate selected early morphological developments in the ancestors of mammals to the demands
of endothermic homeothermy.
Solution
Endothermic organisms are those organisms that maintain constant body temperature irrespective
of the environmental temperature. This constant regulation of temperature (Homeothermy) is due
to well developed metabolism in Mammales. Mitochondria play a crucial role in maintain
Homeothermy
Mammals evolved from a group of reptiles called the synapsids. A branch of the synapsids called
the therapsids appeared by the middle of the Permian Period (275 to 225 million years ago).
Over millions of years some of thetherapsids would evolve many features that would later be
associated with mammals.
The hallmarks of today\'s mammals are presence of hair, warm blood and milk-producing glands.
- Some dinosaurs, such as the Stegosaurus and Dimetrodon, supported large plates or sails of
skin, developed to function as solar panels, absorbing the sun\'s heat for quick mobilization.
However, during the period of dinosaurs, some of the sail-backed pelycosaurs (which includes
the Dimetrodon) lost their sails. It would be improbable that such an effective heating
mechanism would be lost through evolution unless a more efficient method of heat control had
evolved to replace it. It is therefore reasonable to supposed that the pelycosaurs and their
successors, the therapsids, were to some degree endothermic. The therapsids, being only three
feet long, would need some form of body insulation if it was to be effective. Thus, it is
reasonable to conclude that some of these creatures were covered in hair, or fur..
Question VI. In 1976, Hozumi and Tonegawa published an elegant paper.pdf
Question VI. In 1976, Hozumi and Tonegawa published an elegant paper (Proc. Natl. Acad. Sci.
USA 73, 3628-3632, 1976) showing that a V gene and a C gene are miles apart in germline DNA
(from mouse embryos), but next to each other in antibody-coding DNA (from a myeloma tumor).
Subsequent experiments have demonstrated unequivocally that the immune system generates the
antibody diversity by shuffling a few hundred genes to create countless permutations, in a
process called V(D)J recombination. In this process, RAG enzymes work as a multi-subunit
complex to induce cleavage of a double-stranded DNA molecule between the antigen receptor
coding segment and a flanking recombination signal sequence (RSS). They do this in two steps.
They initially introduce a ‘nick’ in the 5\' (upstream) end of the RSS heptamer (a conserved
region of 7 nucleotides) that is adjacent to the coding sequence, leaving behind a 3\'-hydroxyl
group at the coding end and a 5\'-phosphate group at the RSS end. The next step couples these
chemical groups, binding the OH-group (on the coding end) to the PO4group (that is sitting
between the RSS and the gene segment on the opposite strand). [Assess each subsequent
statement (64-71) as either factually correct (= “true”) or incorrect (= “false”)]:
64. This is an important enzymatic step in a process known as somatic recombination, which is
limited to macrophages.
65. This is an event of the mechanism of genetic recombination in the early stages of Ig and
TCRs production.
66. This produces a 3\'-phosphorylated double-stranded break at the RSS and a covalently closed
hairpin at the coding end.
67. This produces a 3\'-phosphorylated double-stranded break at the RSS and a non-covalently
closed hairpin at the coding end.
68. This produces a 5\'-phosphorylated double-stranded break at the RSS and a covalently-closed
hairpin at the coding end.
69. This produces a 5\'-phosphorylated double-stranded break at the RSS and a non-covalently
closed hairpin at the coding end.
70. This is an event of the mechanism of genetic recombination in the late stages of
immunoglobulin (Ig) and T-cell receptors (TCRs) production.
71. The V(D)J recombination events are involved in somatic hypermutations of the TCR and the
binding of the OH-group (on the coding DNA end) to the PO4-group (that is sitting between the
RSS and the gene segment on the opposite DNA strand) plays an important role in these
hypermutations, which contribute to generating TCR diversity.
Solution
64. False
This process is not limited to macrophages and occurs in the B cells and T cells.
65. True
This occurs in early stages of production of T cell receptors as well as immunoglobulins.
66. False
No 3\'-phosphorylated double-stranded break is produced
67. False
No 3\'-phosphorylated double-stranded break is produced
68. True
Yes, 5\'-phosphorylated break is produced at the RSS as well as on the coding end a covalently
closed- hairpin is formed.
69. False
Non- covalently closed hairpin is not .

accurate as the genome of a modern human. Therefore we may have the potential to recreate a
Neanderthal – would you be interested in trying to recreate extinct species from genome
sequences?
Solution
The book and the movie Jurassic Park presented a masterpiece in sci-fi which ignited young
minds with the spark of innovation and engineering in the field of genetic manipulation of
organisms. The below are the points in response to the given question.
(1) In my knowledge of science philosophy, creating and innovating in science is not (rather
should not be) ONLY limited by theoretical or practical feasibilities but rather by ethics. Human
is a social animal and is bound and institutionalized within its filial and geographical boundaries.
Creating extinct races of humans, such as Neanderthals, will certainly pose complexities of
maternal and paternal relations. Such an individual will face issues of emotional, psychological
and cultural development.
(2) Another aspect of looking at the given question would be related to the individual\'s
acclimatization in the present earth environs. The Neanderthals used to inhabit the earth about
40000 ybp. Given the present time\'s phenomenon of global climate change and warming one
might believe that the set of climatic parameters 40000 ybp were certainly and completely
different that those of the present. Creating and bringing an individual of 40000 years before
time would certainly be an act of pure science experiment without social and human perspectives
kept in mind.
Thirdly, the important aspect would be the place of the individual in the global food chain. The
species in nature develop so as to fit in a crucial and defined role and place in energy transfer in
ecological food web.
In a nutshell, such created Neanderthals would be out of place and time in the current world
scenarios. They will face climatic, cultural and ecological shock. Such individuals will be only a
retrogressive science experiment with perhaps no contribution in research and development..

Prior to the development of anti-retroviral drugs, HIV infected pati.pdf
Prior to the development of anti-retroviral drugs, HIV infected patients with AIDS developed a
high frequency of Kaposi’s sarcoma. Why?
a. Compromised Immune surveillance promotes the spontaneous appearance of Kaposi’s
sarcoma.
b. High levels of HIV replication in AIDS patients cause Kaposi’s sarcoma.
c. Latent EBV is reactivated and causes Kaposi’s sarcoma.
d. Latent HHV-8 is reactivated and causes Kaposi’s sarcoma.
Solution
Kaposi\'s sarcoma (KS) is a tmors with tiny new blood vessels grow under the the skin and in
membranes of your mouth, nostril, eyes, and anus. It can spread in lungs, liver, stomach,
intestines, and lymph nodes, which are glands that help fight contamination.
The failure of a tumor to develop as it does within the immunosuppressive host might be not due
to a loss of tumor-cell killing within the suppressed host. Instead, the better degree of immune
response , even to tumor-inhibitory ranges, probably offers less fine guide to tumor increase.
Because humans with HIV have weakened immune systems, they may be much more likely to
expand KS. Most severe instances happen when a person has AIDS, the HIV contamination,
however skin lesions can also show up in advance. They\'re a signal for high immune system
Both EBV and KSHV are latent residents in B lymphocytes and display sporadic reactivation in
lymphoepithelial tissues including tonsils .Lytic reactivation of EBV or KSHV in epithelial cells
of the nasopharynx is strongly inspired by the differentiation. In addition, XBP-1s, a made from
the gene accountable for B cellular differentiation, turned into currently suggested to be one of
the physiological stimuli that trigger the lytic switch of EBV and KSHV in latently infected B
cells.With the aid of infection with human herpesvirus eight (HHV8), also known as Kaposi
sarcoma-related herpesvirus (KSHV) or KS agent.

Amnesty international was know as Amnesty and AI. It is a non governmental organisation deals
with human rights with 7 million members in the world.
History: It was founded in London in July 1961 by English labour lawyer Peter Benenson. In
1967 Peter Benenson resigned after an independent inquiry did not support his claims that AI
had been infiltrated by British agents. Later he claimed that the Central Intelligence Agency had
become involved in Amnesty.
In 1970 it was led by Seán MacBride and Martin Ennals.
In 1980 Amnesty International was drawing more criticism from governments. The USSR
alleged that Amnesty International conducted espionage, the Moroccan government denounced it
as a defender of lawbreakers, and the Argentinian government banned Amnesty International\'s
1983 annual report.
Throughout the 1990s, Amnesty International continued to grow, to a membership of over 7
million in over 150 countries and territories,[2]led by Senegalese Secretary General Pierre Sané.
After 2000, Amnesty International\'s agenda turned to the challenges arising from globalisation

ort Answer 1) Why would migration to an island by a single p.pdf
ort Answer: 1) Why would migration to an island by a single pair of birds be likely to lead to
adaptive radiation in their descendants?
Solution
1) The law of adaptive radiation by Osborn postulates, \"each isolated region, if large and
sufficiently varied in its topography, soil, climate and vegetation, will give rise to a diverse
fauna; the larger the region and more diverse teh conditions, the greater will be the variation of
animals found\". Thus, the pair of birds entering an island will be prone to variations in
topography and biological entities leading to adaptations in their features to lead a survival. The
factors which would influence their adaptative radiation are need for food, need for safety, need
for better breeding grounds, absence of enemies, presence of unoccupied environmental niches
and isolation.
2) The incompleteness of fossils is caused by the following factors:
Most of the animals and plants do not get suitable conditions for fossilization. They are
destroyed by destructive forces.

Solution
The human brain has three main parts: cerebrum, brain stem and the cerebellum. Cerebrum is the
major part that is divided into two hemispheres. There are four lobes harbored by the cerebrum:
frontal lobe, parietal lobe, temporal lobe and occipital lobe.
The frontal lobe is associated with memory, thinking process, behavior and movement.
The parietal lobe handles the sensory information related to taste and touch and has some
functions relating to language.
Occipital lobe is responsible for vision.
The temporal lobe functions to control hearing, language, speech, memory and emotions.
The cerebellum is important in maintenance of posture and balance of the body. It also controls
motor movements.
The brain stem transfers information between the brain and the body and has role in breathing
and functioning of heart..

In groups, start with a brainstorming session on what you know and do.pdf
In groups, start with a brainstorming session on what you know and don\'t know about
mosquitoes in general. The class will compare lists to see how much collective information we
can gather. Include, specifically, these questions in your brainstorming: Why were the
researchers planning to use only female mosquitoes? Why do female mosquitoes bite for a blood
\"meal\" in the first place? What do male and female mosquitoes live on as their main nutrient
source (if only females take blood meals)? Continuing in your groups, work on the following:
Based on the information above, write a plausible hypothesis that describes a possible
mechanism to explain the differences between the forest and domestic forms in terms of their
specific preferences for humans Based on your hypothesis, write one or more specific
predictions that you could experimentally test. Draw a cartoon of a specific experiment you
would want to design to test your predictions. During the lab meeting described in Part I of this
case study. Carolyn brought up the concept of \"what makes a species one species.\" The most
common way that scientists define species is called the \'biological species concept\" (BSC).
Define the BSC What are the criteria used in the BSC in define a species?
Solution
Blood-feeding as a behavioural adaptation is exceedingly rare in insects. Of the 1-10 million
insect species on earth, only ~10,000 feed on the blood of live animals. Among these, only about
100 species blood-feed preferentially on humans. When biting insects evolve to prefer humans,
they can spread diseases such as malaria and dengue fever with devastating efficiency. The
mosquito Aedes aegypti provides one of the best examples of specialization on humans. It
originated as a wild, animal-biting species in the forested areas of sub-Saharan Africa, where the
subspecies Ae. aegypti formosus is still often found living in forests and biting non-human
animals today. The derived non-African subspecies Ae. aegypti aegypti, in contrast, has evolved
to specialise in biting humans and thus has become the major worldwide vector of dengue and
yellow fevers.
The evolutionary adaptations that help subspecies aegypti exploit humans are most clearly seen
where it has been reintroduced along the coast of East Africa and is known as the ‘domestic’
form. Researchers investigating the outbreak of an unknown illness in Tanganyika in 1952
discovered homes heavily populated by brown-pigmented ‘domestic’ mosquitoes. Subsequent
work in the Rabai region of Kenya in the 1960s and 1970s showed that domestic mosquitoes
readily entered homes, preferred to lay eggs in nutrient-poor river and rain water stored in
containers indoors, were resistant to starvation as larvae, and had evolved a strong preference for
biting humans. Black-pigmented populations of the native African subspecies formosus, known
in Rabai as the ‘forest’ form, were found just hundreds of meters away avoiding homes, laying
their eggs in tree holes and ro.

Persistent Data Structures
A persistent data structure is one in which we can make changes (such as inserting and removing
elements) while still preserving the original data structure Of course, an easy way to do this is to
create a new copy of the entire data structure every time we perform an operation that changes
the data structure, but it is much more efficient to only make a copy of the smallest possible
portion of the data structure.
First, let\'s look at one of the easiest possible data structures — a stack, implemented using a
linked list.
Persistent Stack
Let\'s say that we have a stack S1, and we want to create a new stack S2, which is the result of
pushing a new element X onto S1, without changing S1 at all. This is easy — we just add a new
element that points to S1:
Starting with the stack S1:
We push X on S1, to get S2, leaving S1 as it was. So after the operation we have two versions of
the stack S1 the older version with elements A, B and C and S2 the newer version with elements
X, A, B and C.
What about popping? That works in the same way. Starting with our original S1 (elements A, B
and C), we can pop off the first element (A), to get S2:
What if we want to push something on to this new stack? It works in the same was as before – if
we push an X onto S2 above to get S3, we have
So for every operation you make a new version of the stack while reusing any existing stack
elements.
You will have to make a linked list of pointers that will point to the head of the different stack
versions.
Also each stack is also implemented as a linked list of elements SAB

Farmer Brown plans on adding fertilizer to his crop. However, hes a.pdf
Farmer Brown plans on adding fertilizer to his crop. However, he\'s a little nervous because the
last time he used fertilizer many of the plants wilted and some even turned brown and died. Why
did this \"fertilizer burn\" occur in terms of water potential, and what could Farmer Brown do to
enable him to add the same amount of fertilizer while being more likely to avoid this problem?
Solution
The plants suffered from fertilizer burn because farmer brown overdozed the plants with
excessive fertilizer which dessicated the plant tissues due to increased osmotic stress creating a
state of hypertonicity.
Farmer Brown can avoid the recurrence of the same event by applying only dilute or controlled
release fertilizer..

What aspects of today\'s information economy have influenced the importance of building
partnerships?
Solution
A revolution in information and communications technology is transforming the way we live
and work. Information Communication Technoloy is becoming the largest distribution platform
of providing public and private services to millions of people in rural and poor areas. It is
changing the way we deliver education and business services, design buildings and cities, and
manufacture engines and cars. Market information, financial services, education and health
services had largely been unavailable in those areas in the past due to lack of connectivity of any
kind. Increases productivity and makes the market work more efficiently reaching population
with low levels of income and literacy. A recognisable new dynamic force – the information
economy – has emerged, and is transforming every other sector. The principles of business
strategy are being transformed from focusing on physical assets and economies of scale to the
drivers of success which reside in connectivity and intangibles. Businesses need to develop and
manage complex ecologies or organizations around themselves so as to succeed. Barriers
between companies, which used to be solid and absolute, are now permeable. Through virtual
integration, the walls between enterprises crumble. Cyber security underpins the information
economy. Without it businesses and consumers would not have the trust and confidence to use
the internet and other digital technologies. People and businesses expect the right information to
be available, all the time, and anywhere. Through trends such as cloud computing, software
services and data are hosted away from users but are accessible on demand, any place or time.
This week, we are going to work together as a class to assist the Lon.pdf
This week, we are going to work together as a class to assist the Lone Star Center for Disease
Control. They have identified a closed population of 10, 000 individuals, where a particularly
nasty strain of flu virus has started to spread. What we know about this particular virus: It
spreads at a rate that is jointly proportional to both the number of infected individuals and then
number of uninfected individuals. When 1, 000 individuals are infected, the rate at which
individuals are becoming infected is 500 individuals per day. There are currently 200 individuals
infected. The LSCDC has determined that it is critical for relief efforts that they know how long
it will take, based upon available information, for 90% of the population to become infected with
the virus. You are not required to solve this entire problem on your own. Post at least the
equivalent of 50 words that contributes to us solving this together throughout the course of the

Take a position on this statement The media represent realistic ima.pdf
The document discusses whether media represents realistic images of Arabs. It argues that media does not, citing a survey that found nearly 50% of adults believe there is persistent negative media bias against Muslims and Arabs in media. As evidence, it notes that in films, the villain is often Arab or Muslim, while the hero is non-Arab. This negative portrayal increases when a group is seen as a security threat. Hispanics have also faced long-term negative bias in media related to immigration debates.
Relate selected early morphological developments in the ancestors of.pdf
Relate selected early morphological developments in the ancestors of mammals to the demands
of endothermic homeothermy.
Solution
Endothermic organisms are those organisms that maintain constant body temperature irrespective
of the environmental temperature. This constant regulation of temperature (Homeothermy) is due
to well developed metabolism in Mammales. Mitochondria play a crucial role in maintain
Homeothermy
Mammals evolved from a group of reptiles called the synapsids. A branch of the synapsids called
the therapsids appeared by the middle of the Permian Period (275 to 225 million years ago).
Over millions of years some of thetherapsids would evolve many features that would later be
associated with mammals.
The hallmarks of today\'s mammals are presence of hair, warm blood and milk-producing glands.
- Some dinosaurs, such as the Stegosaurus and Dimetrodon, supported large plates or sails of
skin, developed to function as solar panels, absorbing the sun\'s heat for quick mobilization.
However, during the period of dinosaurs, some of the sail-backed pelycosaurs (which includes
the Dimetrodon) lost their sails. It would be improbable that such an effective heating
mechanism would be lost through evolution unless a more efficient method of heat control had
evolved to replace it. It is therefore reasonable to supposed that the pelycosaurs and their
successors, the therapsids, were to some degree endothermic. The therapsids, being only three
feet long, would need some form of body insulation if it was to be effective. Thus, it is
reasonable to conclude that some of these creatures were covered in hair, or fur..
Question VI. In 1976, Hozumi and Tonegawa published an elegant paper.pdf
Question VI. In 1976, Hozumi and Tonegawa published an elegant paper (Proc. Natl. Acad. Sci.
USA 73, 3628-3632, 1976) showing that a V gene and a C gene are miles apart in germline DNA
(from mouse embryos), but next to each other in antibody-coding DNA (from a myeloma tumor).
Subsequent experiments have demonstrated unequivocally that the immune system generates the
antibody diversity by shuffling a few hundred genes to create countless permutations, in a
process called V(D)J recombination. In this process, RAG enzymes work as a multi-subunit
complex to induce cleavage of a double-stranded DNA molecule between the antigen receptor
coding segment and a flanking recombination signal sequence (RSS). They do this in two steps.
They initially introduce a ‘nick’ in the 5\' (upstream) end of the RSS heptamer (a conserved
region of 7 nucleotides) that is adjacent to the coding sequence, leaving behind a 3\'-hydroxyl
group at the coding end and a 5\'-phosphate group at the RSS end. The next step couples these
chemical groups, binding the OH-group (on the coding end) to the PO4group (that is sitting
between the RSS and the gene segment on the opposite strand). [Assess each subsequent
statement (64-71) as either factually correct (= “true”) or incorrect (= “false”)]:
64. This is an important enzymatic step in a process known as somatic recombination, which is
limited to macrophages.
65. This is an event of the mechanism of genetic recombination in the early stages of Ig and
TCRs production.
66. This produces a 3\'-phosphorylated double-stranded break at the RSS and a covalently closed
hairpin at the coding end.
67. This produces a 3\'-phosphorylated double-stranded break at the RSS and a non-covalently
closed hairpin at the coding end.
68. This produces a 5\'-phosphorylated double-stranded break at the RSS and a covalently-closed
hairpin at the coding end.
69. This produces a 5\'-phosphorylated double-stranded break at the RSS and a non-covalently
closed hairpin at the coding end.
70. This is an event of the mechanism of genetic recombination in the late stages of
immunoglobulin (Ig) and T-cell receptors (TCRs) production.
71. The V(D)J recombination events are involved in somatic hypermutations of the TCR and the
binding of the OH-group (on the coding DNA end) to the PO4-group (that is sitting between the
RSS and the gene segment on the opposite DNA strand) plays an important role in these
hypermutations, which contribute to generating TCR diversity.
Solution
64. False
This process is not limited to macrophages and occurs in the B cells and T cells.
65. True
This occurs in early stages of production of T cell receptors as well as immunoglobulins.
66. False
No 3\'-phosphorylated double-stranded break is produced
67. False
No 3\'-phosphorylated double-stranded break is produced

Yes, 5\'-phosphorylated break is produced at the RSS as well as on the coding end a covalently

accurate as the genome of a modern human. Therefore we may have the potential to recreate a
Neanderthal – would you be interested in trying to recreate extinct species from genome
sequences?
Solution
The book and the movie Jurassic Park presented a masterpiece in sci-fi which ignited young
minds with the spark of innovation and engineering in the field of genetic manipulation of
organisms. The below are the points in response to the given question.
(1) In my knowledge of science philosophy, creating and innovating in science is not (rather
should not be) ONLY limited by theoretical or practical feasibilities but rather by ethics. Human
is a social animal and is bound and institutionalized within its filial and geographical boundaries.
Creating extinct races of humans, such as Neanderthals, will certainly pose complexities of
maternal and paternal relations. Such an individual will face issues of emotional, psychological
and cultural development.
(2) Another aspect of looking at the given question would be related to the individual\'s
acclimatization in the present earth environs. The Neanderthals used to inhabit the earth about
40000 ybp. Given the present time\'s phenomenon of global climate change and warming one
might believe that the set of climatic parameters 40000 ybp were certainly and completely
different that those of the present. Creating and bringing an individual of 40000 years before
time would certainly be an act of pure science experiment without social and human perspectives
kept in mind.
Thirdly, the important aspect would be the place of the individual in the global food chain. The
species in nature develop so as to fit in a crucial and defined role and place in energy transfer in
ecological food web.
In a nutshell, such created Neanderthals would be out of place and time in the current world
scenarios. They will face climatic, cultural and ecological shock. Such individuals will be only a
retrogressive science experiment with perhaps no contribution in research and development..

Prior to the development of anti-retroviral drugs, HIV infected pati.pdf
Prior to the development of anti-retroviral drugs, HIV infected patients with AIDS developed a
high frequency of Kaposi’s sarcoma. Why?
a. Compromised Immune surveillance promotes the spontaneous appearance of Kaposi’s
sarcoma.
b. High levels of HIV replication in AIDS patients cause Kaposi’s sarcoma.
c. Latent EBV is reactivated and causes Kaposi’s sarcoma.
d. Latent HHV-8 is reactivated and causes Kaposi’s sarcoma.
Solution
Kaposi\'s sarcoma (KS) is a tmors with tiny new blood vessels grow under the the skin and in
membranes of your mouth, nostril, eyes, and anus. It can spread in lungs, liver, stomach,
intestines, and lymph nodes, which are glands that help fight contamination.
The failure of a tumor to develop as it does within the immunosuppressive host might be not due
to a loss of tumor-cell killing within the suppressed host. Instead, the better degree of immune
response , even to tumor-inhibitory ranges, probably offers less fine guide to tumor increase.
Because humans with HIV have weakened immune systems, they may be much more likely to
expand KS. Most severe instances happen when a person has AIDS, the HIV contamination,
however skin lesions can also show up in advance. They\'re a signal for high immune system
Both EBV and KSHV are latent residents in B lymphocytes and display sporadic reactivation in
lymphoepithelial tissues including tonsils .Lytic reactivation of EBV or KSHV in epithelial cells
of the nasopharynx is strongly inspired by the differentiation. In addition, XBP-1s, a made from
the gene accountable for B cellular differentiation, turned into currently suggested to be one of
the physiological stimuli that trigger the lytic switch of EBV and KSHV in latently infected B
cells.With the aid of infection with human herpesvirus eight (HHV8), also known as Kaposi
sarcoma-related herpesvirus (KSHV) or KS agent.

Amnesty international was know as Amnesty and AI. It is a non governmental organisation deals
with human rights with 7 million members in the world.
History: It was founded in London in July 1961 by English labour lawyer Peter Benenson. In
1967 Peter Benenson resigned after an independent inquiry did not support his claims that AI
had been infiltrated by British agents. Later he claimed that the Central Intelligence Agency had
become involved in Amnesty.
In 1970 it was led by Seán MacBride and Martin Ennals.
In 1980 Amnesty International was drawing more criticism from governments. The USSR
alleged that Amnesty International conducted espionage, the Moroccan government denounced it
as a defender of lawbreakers, and the Argentinian government banned Amnesty International\'s
1983 annual report.
Throughout the 1990s, Amnesty International continued to grow, to a membership of over 7
million in over 150 countries and territories,[2]led by Senegalese Secretary General Pierre Sané.
After 2000, Amnesty International\'s agenda turned to the challenges arising from globalisation

ort Answer 1) Why would migration to an island by a single p.pdf
ort Answer: 1) Why would migration to an island by a single pair of birds be likely to lead to
adaptive radiation in their descendants?
Solution
1) The law of adaptive radiation by Osborn postulates, \"each isolated region, if large and
sufficiently varied in its topography, soil, climate and vegetation, will give rise to a diverse
fauna; the larger the region and more diverse teh conditions, the greater will be the variation of
animals found\". Thus, the pair of birds entering an island will be prone to variations in
topography and biological entities leading to adaptations in their features to lead a survival. The
factors which would influence their adaptative radiation are need for food, need for safety, need
for better breeding grounds, absence of enemies, presence of unoccupied environmental niches
and isolation.
2) The incompleteness of fossils is caused by the following factors:
Most of the animals and plants do not get suitable conditions for fossilization. They are
destroyed by destructive forces.

The human brain has three main parts: cerebrum, brain stem and the cerebellum. Cerebrum is the
major part that is divided into two hemispheres. There are four lobes harbored by the cerebrum:
frontal lobe, parietal lobe, temporal lobe and occipital lobe.
The frontal lobe is associated with memory, thinking process, behavior and movement.
The parietal lobe handles the sensory information related to taste and touch and has some
functions relating to language.
Occipital lobe is responsible for vision.
The temporal lobe functions to control hearing, language, speech, memory and emotions.
The cerebellum is important in maintenance of posture and balance of the body. It also controls
motor movements.
The brain stem transfers information between the brain and the body and has role in breathing
and functioning of heart..

In groups, start with a brainstorming session on what you know and do.pdf
In groups, start with a brainstorming session on what you know and don\'t know about
mosquitoes in general. The class will compare lists to see how much collective information we
can gather. Include, specifically, these questions in your brainstorming: Why were the
researchers planning to use only female mosquitoes? Why do female mosquitoes bite for a blood
\"meal\" in the first place? What do male and female mosquitoes live on as their main nutrient
source (if only females take blood meals)? Continuing in your groups, work on the following:
Based on the information above, write a plausible hypothesis that describes a possible
mechanism to explain the differences between the forest and domestic forms in terms of their
specific preferences for humans Based on your hypothesis, write one or more specific
predictions that you could experimentally test. Draw a cartoon of a specific experiment you
would want to design to test your predictions. During the lab meeting described in Part I of this
case study. Carolyn brought up the concept of \"what makes a species one species.\" The most
common way that scientists define species is called the \'biological species concept\" (BSC).
Define the BSC What are the criteria used in the BSC in define a species?
Solution
Blood-feeding as a behavioural adaptation is exceedingly rare in insects. Of the 1-10 million
insect species on earth, only ~10,000 feed on the blood of live animals. Among these, only about
100 species blood-feed preferentially on humans. When biting insects evolve to prefer humans,
they can spread diseases such as malaria and dengue fever with devastating efficiency. The
mosquito Aedes aegypti provides one of the best examples of specialization on humans. It
originated as a wild, animal-biting species in the forested areas of sub-Saharan Africa, where the
subspecies Ae. aegypti formosus is still often found living in forests and biting non-human
animals today. The derived non-African subspecies Ae. aegypti aegypti, in contrast, has evolved
to specialise in biting humans and thus has become the major worldwide vector of dengue and
yellow fevers.
The evolutionary adaptations that help subspecies aegypti exploit humans are most clearly seen
where it has been reintroduced along the coast of East Africa and is known as the ‘domestic’
form. Researchers investigating the outbreak of an unknown illness in Tanganyika in 1952
discovered homes heavily populated by brown-pigmented ‘domestic’ mosquitoes. Subsequent
work in the Rabai region of Kenya in the 1960s and 1970s showed that domestic mosquitoes
readily entered homes, preferred to lay eggs in nutrient-poor river and rain water stored in
containers indoors, were resistant to starvation as larvae, and had evolved a strong preference for
biting humans. Black-pigmented populations of the native African subspecies formosus, known
in Rabai as the ‘forest’ form, were found just hundreds of meters away avoiding homes, laying
their eggs in tree holes and ro.

Persistent Data Structures
A persistent data structure is one in which we can make changes (such as inserting and removing
elements) while still preserving the original data structure Of course, an easy way to do this is to
create a new copy of the entire data structure every time we perform an operation that changes
the data structure, but it is much more efficient to only make a copy of the smallest possible
portion of the data structure.
First, let\'s look at one of the easiest possible data structures — a stack, implemented using a
linked list.
Persistent Stack
Let\'s say that we have a stack S1, and we want to create a new stack S2, which is the result of
pushing a new element X onto S1, without changing S1 at all. This is easy — we just add a new
element that points to S1:
Starting with the stack S1:
We push X on S1, to get S2, leaving S1 as it was. So after the operation we have two versions of
the stack S1 the older version with elements A, B and C and S2 the newer version with elements
X, A, B and C.
What about popping? That works in the same way. Starting with our original S1 (elements A, B
and C), we can pop off the first element (A), to get S2:
What if we want to push something on to this new stack? It works in the same was as before – if
we push an X onto S2 above to get S3, we have
So for every operation you make a new version of the stack while reusing any existing stack
elements.
You will have to make a linked list of pointers that will point to the head of the different stack
versions.
Also each stack is also implemented as a linked list of elements SAB

How is the population on Earth protected from each radiation type A.pdf
How is the population on Earth protected from each radiation type? And explaine it.
Solution
The population are protected by the earth from harmful radiations of the sum.
Cosmic rays: are high energy particles thrown at the speed of light. They bLast right through our
body damaging the DNA. Such harmful rays are collided by oxygen and nitrogen particles in the
atmosphere thus protecting us.
Gamma&x rays: They are potentiak enough to damage our cells but the molecules in the atm.
Absorb them and give protection.
Uv radiation: sun always throws uv rafiation onto earth and earth inturn has a blanket called
ozone layer to get protected from it.
Sun flares: also kept away by the atmosphere.
Vacuum: the temp. Of vacuum is too cold but our earth is protected by green house gases to
maintain warmth.
It is believed that the earths magnetic field also keeps awsy harmful radiations from sun and
diverts them to anothet path.
Layers of Atmosphere:
There are 5 layers approx. 60 km thick.
Troposphere: First layer near surface of earth. It provides majoriy of oxygen and protect from
drought.

Farmer Brown plans on adding fertilizer to his crop. However, hes a.pdf
Farmer Brown plans on adding fertilizer to his crop. However, he\'s a little nervous because the
last time he used fertilizer many of the plants wilted and some even turned brown and died. Why
did this \"fertilizer burn\" occur in terms of water potential, and what could Farmer Brown do to
enable him to add the same amount of fertilizer while being more likely to avoid this problem?
Solution
The plants suffered from fertilizer burn because farmer brown overdozed the plants with
excessive fertilizer which dessicated the plant tissues due to increased osmotic stress creating a
state of hypertonicity.
Farmer Brown can avoid the recurrence of the same event by applying only dilute or controlled
release fertilizer..

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
9
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.
