Find the indicial roots then solve the following ODE using series. Yo.pdf
Find the indicial roots then solve the following ODE using series. You must show the first 4
terms of each series. xy\" + 2y\' + xy = 0
Solution
Ans-
Let X be a set and let be a family of subsets of X. Then is called a topology on X if:[1][2]
If is a topology on X, then the pair (X, ) is called a topological space. The notation X may be
used to denote a set X endowed with the particular topology .
The members of are called open sets in X. A subset of X is said to be closed if its complement is
in (i.e., its complement is open). A subset of X may be open, closed, both (clopen set), or
neither. The empty set and X itself are always both closed and open.
Basis for a topology
Main article: Basis (topology)
A base (or basis) B for a topological space X with topology T is a collection of open sets in T
such that every open set in T can be written as a union of elements of B.[3][4] We say that the
base generates the topology T. Bases are useful because many properties of topologies can be
reduced to statements about a base that generates that topology—and because many topologies
are most easily defined in terms of a base that generates them.
Subspace and quotient
Every subset of a topological space can be given the subspace topology in which the open sets
are the intersections of the open sets of the larger space with the subset. For any indexed family
of topological spaces, the product can be given the product topology, which is generated by the
inverse images of open sets of the factors under the projection mappings. For example, in finite
products, a basis for the product topology consists of all products of open sets. For infinite
products, there is the additional requirement that in a basic open set, all but finitely many of its
projections are the entire space.
A quotient space is defined as follows: if X is a topological space and Y is a set, and if f : XY is
a surjective function, then the quotient topology on Y is the collection of subsets of Y that have
open inverse images under f. In other words, the quotient topology is the finest topology on Y for
which f is continuous. A common example of a quotient topology is when an equivalence
relation is defined on the topological space X. The map f is then the natural projection onto the
set of equivalence classes.
Examples of topological spaces
A given set may have many different topologies. If a set is given a different topology, it is
viewed as a different topological space. Any set can be given the discrete topology in which
every subset is open. The only convergent sequences or nets in this topology are those that are
eventually constant. Also, any set can be given the trivial topology (also called the indiscrete
topology), in which only the empty set and the whole space are open. Every sequence and net in
this topology converges to every point of the space. This example shows that in general
topological spaces, limits of sequences need not be unique. However, often topological spaces
must b.

DNA and RNA are both stands of nucleotides but RNA can carry out for .pdf
DNA and RNA are both stands of nucleotides but RNA can carry out for more functions than
DNA. How docs the structure of RNA differ from DNA? What additional activities/function can
RNA do that DNA cannot?
Solution
The structure of ribonucleic acid is single stranded in which thymine replaces uracil as
complimentary base and other adenine, guanine, cytosine are the nucleotides but
deoxyribonucleic acid is double stranded & duplex.
The additive activities can RNA performing are to undergo \"translation\" to code for proteins
the following are the other functions where as DNA cannot undergo translation directly to code
for proteins
Small nuclear ribonucleic acid (snRNA): It is also known as U-RNA as it contains many uridine
contents in its complex structure. This is composed of 150 nucleotides nearly to produce
spliceosomes and to act along with snRNP. This snRNA has a predominant role in splicing.
mRNA: It is produced by the transcription of DNA in the presence of RNA polymerase enzyme
and it has amino acid coding exons to code for specific proteins as per genetic code.
rRNA (ribosomal RNA): It has 50S and 30S ribosomal subunits which have aminoacyl site and
peptidyl site to carry out translation process during protein synthesis with mRNA.
tRNA (transfer RNA): It has clover leaf structure & common to all tRNA structure. It has
anticodon site to bind to the mRNA and to displace mRNA transcript from nuclear region onto
the rRNA for protein synthesis. It is considered as an adaptor molecule mainly consist of 76 to
90 ribonucleotides in length
piRNA:
Piwi-interacting RNAs (piRNA) are the small non-coding RNA molecules with 26 to 31
nucleotides that are expressed in many of the germ lines of eukaryotic animals. piRNAs interact
with piwi proteins to form RNA-protein complexes..

Solution
An octapeptide was hydrolyzed and the amino acids separated. It was found to have the
following amino acid composition: Gly (1); Ala (2); Val (1); Lys (2); Met (1); Asp (1).
After incubation with FDNB and hydrolysis, 2,4-dinitrophenylalanine was detected.
1-fluoro-2,4-dinitrobenzene (FDNB) is an reagent that always react with N-terminal aminoacid
of a peptide chain and after acid hydrolysis it produces 2.4-dinitrophenyl derivative of
aminoacid. As there is production of 2,4-dinitrophenylalanine, that means alanine is present at
the N-terminal end of the octapeptide.
Treatment with cyanogen bromide, which cleaves at M, resulted in two fragments: a
pentapeptide containing two K residues and a tripeptide containing V, G, and A. (The residues
are not listed in any particular order.)
Cyanogen bromide always cleaves the peptide at the carboxylic end of methionine and after
cleavage it gives two fragments of pentapeptide and tripeptide. So it indicates that methionine is
present at 5th position of the octapeptide.
After treatment with trypsin, which cleaves at R and K, there were 3 fragments: two dipeptides
and MGAV.
Trypsin always cleaves at the carboxy-terminal of arginine and lysine. After cleavage, two
dipeptide and one tetrapeptide (MGAV) is produced. So it is cleared that, the two dipeptide
would be AK and DK.
Therefore the final aminoacid sequence of the octapeptide would be H2N-AKDKMGAV-COOH
Answer: AKDKMGAV.

Why is it important to use several sources of power and influence, r.pdf
Why is it important to use several sources of power and influence, rather than relying on one or
two?
Solution
There are 5 various sources of influence that are as follows
1. Reward power
2. Coercive power
3. Legitimate power
4. Expert power
5. Recent power
Reward power is that in which we can provide reqare for obtaining power
Coercive power is that we can take a disciplinary action to obtain power or to influence for work.
Legitimate power is that which can be granted by your position or rights that as a MD of a
company have a power towards the employees who report him
Expert power is that which is received by your knowledge and experience of any work .
Referent power is that which is related to your reference when you know someone and feel that
you know him means you connect with him
All the five sources of power and influence are important because with the help of all the five
sources we can do the best of himself nothing has been left. And we know every person has
different different thoughts and views. Not all the person preferred same thing . And we don\'t
know the person clearly so if we use all the five sources it helps us to increase or obtaining good
and satisfactory results .
If we use only one or two and rely on it . May be it happens that person don\'t like these two
means these two sources are not good as per that person for obtaining good response. May be it
happens that we wants more position as compared to monetary benefits so if we can use all the
five sources then It makes more chance of better influencing..

What are the advantages of Credit Suisse’s new supplier managemente.pdf
What are the advantages of Credit Suisse’s new supplier management/evaluation system?
Please write in your own words, and atlest 2 paragraphs
Solution
Historically, the IT industry has been mostly a reactive unit. Enterprise IT departments were
essentially order-takers that were quick to adopt the latest programs. Stephen Hilton, managing
director and CIO of technology infrastructure for Credit Suisse, will have none of that. Known
for his stick-to-itiveness and indifference to flavor-of-the-week technology, Hilton has shown
leadership in building a unified culture and developed a reputation for his steady pace of
improvement.
As most Industry leaders know, since 2007 capital markets revenues have decreased rapidly,
resulting in budget cuts across the board. At the same time, most financial institutions had built
up significant fixed costs during the prior decade when revenues were high and budgets were
bloated. \"People were surprised that IT was not as variable as they thought it would be,\" says
Hilton, whose firm has a market capitalization of $42 billion and $1.3 trillion in assets under
management.
At Credit Suisse, only 30% to 40% of IT cost was allocated to staffing, reports Hilton. \"A lot of
the budget covers other IT assets, obligations, liabilities and licensing costs we built up over the
years that just are not variable in a short period of time.\" The only way you can really drive the
cost base down is through business process reengineering, he says, and that\'s exactly what his
team has been working toward.
\"It was quite a learning process for people to understand that. And if I\'m honest, that
realization, a very good realization, has actually changed the business attitude,\" Hilton says.
\"They\'re having different conversations with us now.\" Business leaders are aware that asking
for \"please do it quickly and just get it in\"-style requests aren\'t acceptable anymore. \"They
have to be more patient and more strategic in their decisions.\"
Challenge Silliness
While the old way of approaching technology may have been fitting given the short lifespan of
IT and massive innovation cycles, things began to change in the mid-2000s. For Credit Suisse
the focus shifted to optimizing the company\'s massive, complex infrastructure and improving
end user productivity. As CIO of technology infrastructure, Hilton prepared to make tough
decisions to meet company goals.
\"My view is that at the scale we now run at, process efficiency is key. I am a technologist, but
my master\'s degree is in mechanical engineering and making manufacturing decisions. So I
learned back in the late \'80s about industrialized processes and how to optimize factories. Those
skill sets are what I\'ve applied in the last five years.\" He adds, \"I very much encourage my
teams to be challenging partners. I\'ve spent five years really empowering them, saying, \'Look,

The PRIMARY structure of a protein is:
formed by alpha helices and beta sheets
formed by multiple polypeptide chains binding to one another
formed by dehydration reactions that join amino acids together
all of the above are true
The PRIMARY structure of a protein is:
Solution
option C.
The primrary structure of a protein is formed by dehydration reactions that join amino acids
together.
dehydration reaction removes H2O between two amino acids to form peptide bond. this is the
native primary structure that consists of a linear chain of amino acids.
alpha and beta structures are secondary structures.
tertiary structure involves the interaction between different polypeptide chains..
The figure below shows the chromosomes in a cell for some species (.pdf
The figure below shows the chromosomes in a cell for some species (\"pretend\" that
chromosomes are always visible for this exercise & ignore any nuclear membrane). 1. How
many chromosomes do you see? ___________ Is this haploid or diploid? What do the letters
represent? ___________ Why does the letter \"g\" appear only as lower case but the letter \"F\"
appears as both upper- AND lowercase (F & f)
Solution
1.The number of chromosomes is equal to the number of centromeres.Here in this case ,it is 6
chromosomes.
2.This is haploid as only single chromosomes are seen.
3.The letters represent the alleles of gene.
4.The letter \'g \'appears in the lower case because it is present only in recessive form while \' F\'
appears as both upper and lower case as it is present in both dominant and recessive forms..

A mistake occurs during lambda phage excision from the E. coli genom.pdf
A mistake occurs during lambda phage excision from the E. coli genome: a portion of the E.
colichromosome is excised with the phage genome, leaving behind a portion of the lambda
genome that includes the int gene. This defective genome is packaged and infects an E. coli
strain that is recA- (it lacks RecA). What do you think happens to this genetic material?
1) injected DNA is degraded
2) integrates into new host genome
3) The transferred portion of E. coli chromosome recombines with the new host genome
4) All of these are possible
Solution
The answer is Option no 1 that is injected DNA is degraded.
The defective genome does not carry int gene. So, the lambda phge cannot insert its genetic
material into host genome.
Homologus recombination and DNA reapir does not possible because the host genome is recA-
Strain.(rec A protein plays a major role in homologus recombination)..

1.) Explain what type of mechanism and application use a marine ste.pdf
1.) Explain what type of mechanism and application use a marine steam engine and why?
2.) Explain the history behind a marine steam engine? and compare how it is used in today
society?
Solution
1 a)
Basic operation of a simple reciprocating steam engine
Components of steam engines
There are two fundamental components of a steam engine: the boiler or steam generator, and the
motor unit, itself often referred to as a \"steam engine.\" The two components can either be
integrated into a single unit or can be placed at a distance from each other, in a variety of
configurations.
Other components are often present; pumps (such as an injector) to supply water to the boiler
during operation, condensers to recirculate the water and recover the latent heat of vaporization,
and superheaters to raise the temperature of the steam above its saturated vapor point, and
various mechanisms to increase the draft for fireboxes. When coal is used, a chain or screw
stoking mechanism and its drive engine or motor may be included to move the fuel from a
supply bin (bunker) to the firebox.
Heat source
The heat required for boiling the water and supplying the steam can be derived from various
sources, most commonly from burning combustible materials with an appropriate supply of air in
a closed space (called variously combustion chamber, firebox). In some cases the heat source is a
nuclear reactor or geothermal energy.
Cold sink
As with all heat engines, a considerable quantity of waste heat is produced at relatively low
temperature. This must be disposed of.
The simplest cold sink is simply to vent the steam to the environment. This is often used on
Steam locomotives, but is quite inefficient. Steam locomotive condensing apparatus can be
employed to improve efficiency.
Steam turbines in power stations often use cooling towers which are essentially one form of
condenser.
Sometimes the \"waste heat\" is useful in and of itself, and in those cases very high overall
efficiency can be obtained; for example combined heat and power uses the waste heat for district
heating.
Boilers
Boilers are pressure vessels that contain water to be boiled, and some kind of mechanism for
transferring the heat to the water so as to boil it.
The two most common methods of transferring heat to the water according are:
Once turned to steam, some boilers use superheating to raise the temperature of the steam
further. This allows for greater efficiency.
Motor units
A motor unit takes a supply of steam at high pressure and temperature and gives out a supply of
steam at lower pressure and temperature, using as much of the difference in steam energy as
possible to do mechanical work.
A motor unit is often called \"steam engine\" in its own right. They will also operate on
compressed air or other gas.
Simple expansion
This means that a charge of steam works only once in the cylinder. It is then exhausted directly
into the atmosphere or into a condenser, but remaining heat can be recuperated if needed.
Stars from what part of the main sequence are likely to become black .pdf
Stars from what part of the main sequence are likely to become black holes? Explain your
answer (You may need to look for additional information to answer this question) b)If you were
to look up into the sky for a few hours, and see 100 stars (or take a picture of 100 stars making
up a starfield), why would you see the particular stars that you see out of the billions of stars in
the Universe\'? Include two main reasons (Thinking about magnitude might help you answer this
question) C)Many variable stars are stars in the Yellow or Red Giant stages List at least two such
categories of variable stars.
Solution
a) Most black holes form from the remnants of a large star that dies in a supernova explosion.
(Smaller stars become dense neutron stars, which are not massive enough to trap light.) If the
total mass of the star is large enough (about three times the mass of the Sun), it can be proven
theoretically that no force can keep the star from collapsing under the influence of gravity.
However, as the star collapses, a strange thing occurs. As the surface of the star nears an
imaginary surface called the \"event horizon,\" time on the star slows relative to the time kept by
observers far away. When the surface reaches the event horizon, time stands still, and the star
can collapse no more - it is a frozen collapsing object.
b)
Whether we are able to see an object or not just depends only on the amount of light that is
reaching us and is independent of its size. If you cannot see an object, it just means that the
amount of light coming is not enough for your eye to discern it.
It is true that the angular size of stars is extremely small and that is the reason why no telescope
has ever taken a well resolved picture of a star. For us at the Earth, the atmosphere causes an
angular blurring by scintillation (which is why stars twinkle) and smears their size to about 1
arcsecond (which is 1/3600 of a degree).
Even for telescopes like Hubble which is above the Earth\'s atmosphere, the star\'s angular size is
too small to be resolved. But remember that each star produces a lot of light which is more than
enough for the eye to discern them. Hence we see stars; However they are too small; so we see
them as points and not disks (as you would with planets).
c)
Variable stars may be either intrinsic or extrinsic.
These subgroups themselves are further divided into specific types of variable stars that are
usually named after their prototype. For example, dwarf novae are designated U Geminorum
stars after the first recognized star in the class, U Geminorum..
List what you feel are the advantages and disadvantages of sexual ver.pdf
List what you feel are the advantages and disadvantages of sexual versus asexual reproduction,
and hypothesize what the mode of reproduction tells us about the stability of the environment
each of these types of organisms live integral
Solution
Sexual
Advantages: Increased genetic diversity
Disadvantages: Depending on availability of the other members of the species, it can be
impractical.
Asexual:
Advantages: Can always do it. No need for other individuals.
Disadvantages: Offspring are clones, decreased genetic diversity, which is potentially not ideal
for a population.
If the environment is stable and favorable, organisms prefer sexual reproduction to Asexual
reproduction..
Practice Problem 85 During Drosophila development, adult structures a.pdf
Practice Problem 85 During Drosophila development, adult structures are formed from clusters
of cells called imaginal discs, which are recognizable during larval and pupal stages. You are
interested in the genes expressed in imaginal discs, and you have identified two such genes that
are closely linked together Gene 1 is expressed in the imaginal discs that will become the adult
antennae Gene 2 is expressed in the discs that will become the adult wings and legs. A map of
the two genes is shown here. The arrows indicate the start of transcription. Gene 1 Gene 2
Solution
1. Insulator region acts as an insulator for the construct 13 where it is hiding the I band of
construct 8 . In the table it is showing presence in GFP in antennal discs only. And antennal discs
are expressed by Gene 1 only. So the answer is Gene 1 only.
2. Two enhancers, one for each disc type. In the wing type, it is present for construct 10 and in
leg discs it is present for construct 9..

Name the two laws of inheritance proposed by Gregor Mendel and briefly describe what they are
(2 pts each).
Solution
Mendels law of inheritance
First law : Law of seggregation states that two members of a gene pair called allels separatefrom
each other in formation of gametes. half of the gametes carry one allele and other half carry
another allele.
Second law : Law of independant asssortment states that genes for different traints assort
independantly of one another in the formation of gametes.
Third law ; Law of dominance states that one of the alleles is dominant and other is recessive
which is expressed only when both recessive alleles are present..

Solution
Answer:
7. (d) Adaptive radiation
Adaptive radiation is a process in which organisms diversify rapidly from an ancestral species
into a multitude of new forms, particularly when a change in the environment makes new
resources available, creates new challenges, or opens new environmental niches.
An example of adaptive radiation would be the avian species of the Hawaiian honeycreepers.
Through natural selection, these birds adapted rapidly and converged based on the different
environments of the Hawaiian islands..

Operation Blue Star - Saka Neela Tara
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Why is it important to use several sources of power and influence, r.pdf
Why is it important to use several sources of power and influence, rather than relying on one or
two?
Solution
There are 5 various sources of influence that are as follows
1. Reward power
2. Coercive power
3. Legitimate power
4. Expert power
5. Recent power
Reward power is that in which we can provide reqare for obtaining power
Coercive power is that we can take a disciplinary action to obtain power or to influence for work.
Legitimate power is that which can be granted by your position or rights that as a MD of a
company have a power towards the employees who report him
Expert power is that which is received by your knowledge and experience of any work .
Referent power is that which is related to your reference when you know someone and feel that
you know him means you connect with him
All the five sources of power and influence are important because with the help of all the five
sources we can do the best of himself nothing has been left. And we know every person has
different different thoughts and views. Not all the person preferred same thing . And we don\'t
know the person clearly so if we use all the five sources it helps us to increase or obtaining good
and satisfactory results .
If we use only one or two and rely on it . May be it happens that person don\'t like these two
means these two sources are not good as per that person for obtaining good response. May be it
happens that we wants more position as compared to monetary benefits so if we can use all the
five sources then It makes more chance of better influencing..

What are the advantages of Credit Suisse’s new supplier managemente.pdf
What are the advantages of Credit Suisse’s new supplier management/evaluation system?
Please write in your own words, and atlest 2 paragraphs
Solution
Historically, the IT industry has been mostly a reactive unit. Enterprise IT departments were
essentially order-takers that were quick to adopt the latest programs. Stephen Hilton, managing
director and CIO of technology infrastructure for Credit Suisse, will have none of that. Known
for his stick-to-itiveness and indifference to flavor-of-the-week technology, Hilton has shown
leadership in building a unified culture and developed a reputation for his steady pace of
improvement.
As most Industry leaders know, since 2007 capital markets revenues have decreased rapidly,
resulting in budget cuts across the board. At the same time, most financial institutions had built
up significant fixed costs during the prior decade when revenues were high and budgets were
bloated. \"People were surprised that IT was not as variable as they thought it would be,\" says
Hilton, whose firm has a market capitalization of $42 billion and $1.3 trillion in assets under
management.
At Credit Suisse, only 30% to 40% of IT cost was allocated to staffing, reports Hilton. \"A lot of
the budget covers other IT assets, obligations, liabilities and licensing costs we built up over the
years that just are not variable in a short period of time.\" The only way you can really drive the
cost base down is through business process reengineering, he says, and that\'s exactly what his
team has been working toward.
\"It was quite a learning process for people to understand that. And if I\'m honest, that
realization, a very good realization, has actually changed the business attitude,\" Hilton says.
\"They\'re having different conversations with us now.\" Business leaders are aware that asking
for \"please do it quickly and just get it in\"-style requests aren\'t acceptable anymore. \"They
have to be more patient and more strategic in their decisions.\"
Challenge Silliness
While the old way of approaching technology may have been fitting given the short lifespan of
IT and massive innovation cycles, things began to change in the mid-2000s. For Credit Suisse
the focus shifted to optimizing the company\'s massive, complex infrastructure and improving
end user productivity. As CIO of technology infrastructure, Hilton prepared to make tough
decisions to meet company goals.
\"My view is that at the scale we now run at, process efficiency is key. I am a technologist, but
my master\'s degree is in mechanical engineering and making manufacturing decisions. So I
learned back in the late \'80s about industrialized processes and how to optimize factories. Those
skill sets are what I\'ve applied in the last five years.\" He adds, \"I very much encourage my
teams to be challenging partners. I\'ve spent five years really empowering them, saying, \'Look,
you\'re the experts. Challenge inefficiencies whenever you see them.\'\".

1.) Explain what type of mechanism and application use a marine ste.pdf
1.) Explain what type of mechanism and application use a marine steam engine and why?
2.) Explain the history behind a marine steam engine? and compare how it is used in today
society?
Solution
1 a)
Basic operation of a simple reciprocating steam engine
Components of steam engines
There are two fundamental components of a steam engine: the boiler or steam generator, and the
motor unit, itself often referred to as a \"steam engine.\" The two components can either be
integrated into a single unit or can be placed at a distance from each other, in a variety of
configurations.
Other components are often present; pumps (such as an injector) to supply water to the boiler
during operation, condensers to recirculate the water and recover the latent heat of vaporization,
and superheaters to raise the temperature of the steam above its saturated vapor point, and
various mechanisms to increase the draft for fireboxes. When coal is used, a chain or screw
stoking mechanism and its drive engine or motor may be included to move the fuel from a
supply bin (bunker) to the firebox.
Heat source
The heat required for boiling the water and supplying the steam can be derived from various
sources, most commonly from burning combustible materials with an appropriate supply of air in
a closed space (called variously combustion chamber, firebox). In some cases the heat source is a
nuclear reactor or geothermal energy.
Cold sink
As with all heat engines, a considerable quantity of waste heat is produced at relatively low
temperature. This must be disposed of.
The simplest cold sink is simply to vent the steam to the environment. This is often used on
Steam locomotives, but is quite inefficient. Steam locomotive condensing apparatus can be
employed to improve efficiency.
Steam turbines in power stations often use cooling towers which are essentially one form of
condenser.
Sometimes the \"waste heat\" is useful in and of itself, and in those cases very high overall
efficiency can be obtained; for example combined heat and power uses the waste heat for district
heating.
Boilers
Boilers are pressure vessels that contain water to be boiled, and some kind of mechanism for
transferring the heat to the water so as to boil it.
The two most common methods of transferring heat to the water according are:
Once turned to steam, some boilers use superheating to raise the temperature of the steam
further. This allows for greater efficiency.
Motor units
A motor unit takes a supply of steam at high pressure and temperature and gives out a supply of
steam at lower pressure and temperature, using as much of the difference in steam energy as
possible to do mechanical work.
A motor unit is often called \"steam engine\" in its own right. They will also operate on
compressed air or other gas.
Simple expansion
This means that a charge of steam works only once in the cylinder. It is then exhausted directly
into the atmosphere or into a condenser, but remaining heat can be recuperated if needed.
Stars from what part of the main sequence are likely to become black .pdf
Stars from what part of the main sequence are likely to become black holes? Explain your
answer (You may need to look for additional information to answer this question) b)If you were
to look up into the sky for a few hours, and see 100 stars (or take a picture of 100 stars making
up a starfield), why would you see the particular stars that you see out of the billions of stars in
the Universe\'? Include two main reasons (Thinking about magnitude might help you answer this
question) C)Many variable stars are stars in the Yellow or Red Giant stages List at least two such
categories of variable stars.
Solution
a) Most black holes form from the remnants of a large star that dies in a supernova explosion.
(Smaller stars become dense neutron stars, which are not massive enough to trap light.) If the
total mass of the star is large enough (about three times the mass of the Sun), it can be proven
theoretically that no force can keep the star from collapsing under the influence of gravity.
However, as the star collapses, a strange thing occurs. As the surface of the star nears an
imaginary surface called the \"event horizon,\" time on the star slows relative to the time kept by
observers far away. When the surface reaches the event horizon, time stands still, and the star
can collapse no more - it is a frozen collapsing object.
b)
Whether we are able to see an object or not just depends only on the amount of light that is
reaching us and is independent of its size. If you cannot see an object, it just means that the
amount of light coming is not enough for your eye to discern it.
It is true that the angular size of stars is extremely small and that is the reason why no telescope
has ever taken a well resolved picture of a star. For us at the Earth, the atmosphere causes an
angular blurring by scintillation (which is why stars twinkle) and smears their size to about 1
arcsecond (which is 1/3600 of a degree).
Even for telescopes like Hubble which is above the Earth\'s atmosphere, the star\'s angular size is
too small to be resolved. But remember that each star produces a lot of light which is more than
enough for the eye to discern them. Hence we see stars; However they are too small; so we see
them as points and not disks (as you would with planets).
c)
Variable stars may be either intrinsic or extrinsic.
These subgroups themselves are further divided into specific types of variable stars that are
usually named after their prototype. For example, dwarf novae are designated U Geminorum
stars after the first recognized star in the class, U Geminorum..
List what you feel are the advantages and disadvantages of sexual ver.pdf
List what you feel are the advantages and disadvantages of sexual versus asexual reproduction,
and hypothesize what the mode of reproduction tells us about the stability of the environment
each of these types of organisms live integral
Solution
Sexual
Advantages: Increased genetic diversity
Disadvantages: Depending on availability of the other members of the species, it can be
impractical.
Asexual:
Advantages: Can always do it. No need for other individuals.
Disadvantages: Offspring are clones, decreased genetic diversity, which is potentially not ideal
for a population.
If the environment is stable and favorable, organisms prefer sexual reproduction to Asexual
reproduction..
Practice Problem 85 During Drosophila development, adult structures a.pdf
Practice Problem 85 During Drosophila development, adult structures are formed from clusters
of cells called imaginal discs, which are recognizable during larval and pupal stages. You are
interested in the genes expressed in imaginal discs, and you have identified two such genes that
are closely linked together Gene 1 is expressed in the imaginal discs that will become the adult
antennae Gene 2 is expressed in the discs that will become the adult wings and legs. A map of
the two genes is shown here. The arrows indicate the start of transcription. Gene 1 Gene 2
Solution
1. Insulator region acts as an insulator for the construct 13 where it is hiding the I band of
construct 8 . In the table it is showing presence in GFP in antennal discs only. And antennal discs
are expressed by Gene 1 only. So the answer is Gene 1 only.
2. Two enhancers, one for each disc type. In the wing type, it is present for construct 10 and in
leg discs it is present for construct 9..

Name the two laws of inheritance proposed by Gregor Mendel and brief.pdf
Name the two laws of inheritance proposed by Gregor Mendel and briefly describe what they are
(2 pts each).
Solution
Mendels law of inheritance
First law : Law of seggregation states that two members of a gene pair called allels separatefrom
each other in formation of gametes. half of the gametes carry one allele and other half carry
another allele.
Second law : Law of independant asssortment states that genes for different traints assort
independantly of one another in the formation of gametes.
Third law ; Law of dominance states that one of the alleles is dominant and other is recessive
which is expressed only when both recessive alleles are present..

The ozone layer to form, so that the level of ultraviolet radiation was reduced What is most
likely to occur if a parasite accidentally introduced into the Great Lakes kills 95% of all living
organisms living in the lakes? fusion in a hybrid zone evolution of a surviving organism mass
extinction of the surviving organisms adaptive radiation of the surviving populations: allopatric
speciation in the surviving organisms.
Solution
Answer:
7. (d) Adaptive radiation
Adaptive radiation is a process in which organisms diversify rapidly from an ancestral species
into a multitude of new forms, particularly when a change in the environment makes new
resources available, creates new challenges, or opens new environmental niches.
An example of adaptive radiation would be the avian species of the Hawaiian honeycreepers.
Through natural selection, these birds adapted rapidly and converged based on the different
environments of the Hawaiian islands..

Operation Blue Star - Saka Neela Tara
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

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.
