![Given the following information about a continuous-time LTI system: (1) it is causal, (2) its
system function H(s) is rational and has three poles: -1, -2, and -3, respectively, (3) If x(t) = 5,
then y(t) = 0, (4) h(t = 0^+) = 8, and (5) H(s) has a zero at -1/8, determine the exact form of H(s).
Solution
Ploes are at s=-1,-2,-3
Zero is at s=-1/8
Let H(s)= k*s*(s+1/8)/[(s+1)(s+2)(s+3)]
When x(t)=5, then X(s)=5/s
Y(s)= H(s)*X(s)= k(s+1/8)/[(s+1)(s+2)(s+3)]
= (-k7/16)/(s+1) +(15k/8)/(s+2) -(23k/16)/(s+3)
y(t) = 0,
Now. From initial value theorem
h(0+)= s--> infinity. SH(S)
8 = k

How does the oxygen status of lake sediments affect phosphorus avail.pdf
How does the oxygen status of lake sediments affect phosphorus availability? What is the role of
iron?
Solution
under aerobic condition iron immobilises phospherous and anaerobic condition releases
phospherous. when oxygen is present in the sediments the iron (Fe2+) is oxidised(Fe3+) and it
will precipitates phospherous. Due to this the concentration of phospherous in the lake water will
be very less. if the microorganisms in the lake is utilising oxyygen in the lake , the iron will get
reduced and the phospherous will be released..

How do risk assessment and risk management inform the environmental health policy cycle
How do risk assessment and risk management inform the environmental health policy cycle
Solution
Risk assessment includes evaluation to distinguish the nature and degree of health risks to
humans and ecological receptors from environmental chemical contaminants and other stressors.
That can calculate in environmental health policy cycle by studying the following factors:
After finding of potential hazards, make a record of all significant findings and then review the
record before forwarding to management.
Risk management is managing potential risks and implementation of steps for the beneficial of
the organization. That can achieve by considering following factors:.

For Cooperative Diversity (CD) system, please talk about its potential disadvantages.
Solution
Potential disadvantages of cooperative diversity system
1. Compromise on security :Since different users share data, there is a threat to the privacy and
security of a user\'s data.
2. Limitation due to the non availability of cooperative nodes : To communicate data,
neighbouring nodes called cooperative node provide assistance. But what if there are less number
of nodes or maybe no nodes at all? This is a potential disadvantage.
3. Time delay while using Time Division Multiple Access(TDMA) scheme : Since TDMA
requires that the same frequency channel is to be shared by many and so transmission takes place
one after the other. So, if there are M relays then M+1 time slots are required to send signal..

Explain how the concept of race has developed in the Western world. What are the limitations of
this approach? How have current genetic studies changed this view?
Solution
Physically visible traits, traditionally used in attempts to classify humans into clearly defined
groups(\"races\"), have emphasized such features such as skin color, hair color, hair form, head
shape and nose shape. Throughout the 18th and 19th centuries, American and European
scientists concentrated on describing and classifying biological variations in humans and other
organisms as well. Linnaeus classification, which was based on behavioural and intellectual
abiities divided human in 4 groups.
His ranking system reflects that Europeans are superior to anybody. A German scientist divided
huan popoulation on the basis of skin color: White, yellow. red, brown, and black. The main
concern of the Europeans was religion and how people of different colors fit into that scheme.
All these physical characteristics are not only influenced by several genetic loci but are also
modified by the environment. As a result these traditional markers of race aren\'t reliable
indicator of genetic relationships, they are not biologically useful in depicting patterns of human
diversity.
Since, the middle of 20th century, more precise techniques are allowed a far better understanding
of actual patterns of human variations..

During her quarantine, Mary Mallon secretly had her feces tested by an independent laboratory.
The lab did not detect any Salmonella. How would you explain this finding biologically
Solution
Mary Mallon was an intermittent carrier of typhoid. In intermittent or asymptomatic carriers, the
organism may lie dormant for long periods and reproduce during certain periods. So, the
specimens of the carriers need not necessarily give positive results for the test organism. As
Mary Mallon is an intermittent carrier, her species specimens could be positive sometimes and
negative sometimes..

Understanding the systems of social impact and aggregate knowledge is a key test in

neuronal-type nicotinic receptors (tweleve different subtypes include 210 and 24)
Muscarinic acetyl choline receptors (M1-M5) are involved in the large number of physiological
functions including heart rate and force, contraction of smooth muscles, sensory control as well
as more sensory control including arousal, memory and learning and release of
neurotransmitters. All five are found in CNS, while M1-M4 are found in various tissues.
Nicotinic aceyl choline receptors plays very important role in neurotransmissions like synaptic
transmission and paracrine transmission.nACHR mediates excitatory neurotransmission at
neuronal junction in the brain and spinal cord. They also commonly involved in the modulation
of neurotransmitter release or second messenger systems and calcium signaling.

stands for the rest of the molecule. EXERCISE Based on the olectronegativities of the atoms
involved, predict whether each functional group is polar or nonpolar CHAPTER 2 Water and
Carbon: The Chemical Basis of Life
Solution
Ans. a. Phosphate is an ion. An ion is a chemical species bearing a positive or negative charge.
Note two negative charges on phosphate group.
Ans. b. The weak attractive interaction between a highly electronegative atom (F, O, N) and a H-
atom covalently linked to any such highly electronegative atoms is called hydrogen bond. A
larger difference in the electronegativity of the two atoms in a bond (say, O and H-atoms in a O-
H bond) causes partial charge separation because the electronegative atom pulls the bond
electrons slightly towards itself. Thus, the electronegative atom gets a partial negative charge and
the less electronegative atom gets a partial positive charge. It makes the bond polar (two poles of
charge- a partial negative pole of O-atom, and partial positive charge on H-atom). When a polar
molecule comes in vicinity of another polar group or molecule, the partial positive charge on one
group (molecule) is attracted by partial negative charge on another group (molecule) and vice
versa. This weak attraction is what we call hydrogen bond.
A water (H2O) molecule has both- I. a highly electronegative atom (O- atom), and II. a H-atom
covalently linked to highly electronegative atom.
So, it can form H-bond with a molecule that has-
a highly electronegative atom >> form hydrogen bond with H-atom of water
a H-atom covalently linked to highly electronegative atom >> form hydrogen bond with O-atom
of water
or both A and B
In the given set of groups, all groups (except- thiol, R-SH) have highly electronegative O-atom.
Thus, they all form H-bonds with water.
The S-atoms in thiol group (R-SH) is weakly electronegative. So, the group has low polarity. The
thiol group is also polar (polarity is weaker than that of alcohol) and can form H-bonds with
water, too. However, the resultant H-bonds are much weaker than those formed due to alcohol
(R-OH) groups..

Where is the specific location in an animal where cells are undergoing Meiosis? In a Plant?
Solution
Meiosis is a process by which cell divides. In meiosis cell divides to form four daughter cells,
each with half parental chromosomes i.e half from mother and half from father. So it is evident
that meiosis will takes place in reproductive organs whether it is plants or animals.
In animals meiosis occurs in testes(males) and ovaries(females).
In plants it occurs in anther to form pollen grains and within ovary to form ovules..

Solution
1.
To say we are in interesting times would be an understatement, the recent general election has
plunged us further into uncertainty. Putting aside the rights and wrongs of holding the election
and the unfolding political alliances it’s important to remember that on the ground people and
businesses are struggling to keep up with the changes and the potential impact. Most of us get on
with our lives despite the national turmoil. But the effect of that turmoil is to dampen investment
and decision making; which slows growth. Latest research by the Institute of Directors highlights
that 92% of respondents see current uncertainty over the make-up of the government as a
concern. There has been a negative swing of 34 points in confidence in the UK economy from
their last survey in May. This has serious implications for business growth, as how we interpret
and perceive our future, our risk aversion and our need to have good information to make
decisions can stifle our ability to act.
The national situation we are seeing unfold, in terms of lack of clear majority for either side, and
regardless of eventual party outcome, will be a government relying on a brokered deal to get
things through parliament which will exacerbate this uncertainty and the impact of Brexit fears.
So where can we look to for leadership?
A recent blog by the World Economic Forum has highlighted that in many places the nation state
is looking outdated, and even dangerous. Where power is too centralised and focussed on
national interests, policy is disengaged from the local, from the day to day lives of people and
businesses. The populist movement we are seeing globally is a reaction to this; dissatisfaction
with the way countries are governed creates turbulence in the current way of thinking and doing,
and challenges political structures. Shifting of decision making to a more local level eases
tensions as people see change locally and impact can be seen quicker. Cities are therefore
emerging as key leadership nodes, galvanising action and responding to local need. Focussing on
regional economic growth and giving powers and funding to local delivery structures to improve
growth can help alleviate the social and political tensions that have led us down this unfortunate
path to instability.
Half of humanity lives in cities and urbanization is set.

The number of messages arriving at a multiplexer is a Poisson random .pdf
The number of messages arriving at a multiplexer is a Poisson random variable with mean 15
messages/second. Estimate the probability that more than 950 messages arrive in one
minute.(Bonus problem)
Solution
Possion Distribution
PMF of P.D is = f ( k ) = e- x / x!
Where
= parameter of the distribution.
x = is the number of independent trials
number of messages arriving at a mulfiplexer is a Poisson random variable with
mean 15 messages/second
mean rate for arriving at one minute = 60*15 = 900
P( X > = 950 ) = 1 - P (X < 950) = 0.0504
USE the excel formula = (1-POISSON(950,900,TRUE).

QUESTION 2 Which of the following is not one of the counterproductive.pdf
QUESTION 2 Which of the following is not one of the counterproductive cultural traits that
adversely impact the work climate? O a Hostility to change and a general wariness of new ways
of doing things O b. A highly politicized internal environment O c Company personnel averse to
looking outside the company for best practices O d. Relatively homogeneous top management
team with similar skills O e.A disregard for high ethical standards
Solution
The correct answer is d
Explanation:- Five particularly unhealthy cultural traits are hostility to change, heavily
politicized decision making, insular thinking, unethical and greed driven behaviours and the
presence of incompatible clashing subcultures..
Please answer the following questions only if you know it.Than.pdf
Please answer the following questions only if you know it.
Thank you.
Solution
Answer:
2. (B) Different cells express different set of genes.
Cell differentiation generally depends on changes in gene expression rather than on any changes
in the nucleotide sequence of the cell\'s genome.
3. (A) The type of cell adhesion molecules and cellular junctions.
A fundamental feature of complex multicellular organisms is the molecular adhesion that
governs formation of a distinctive and reproducible multicellular morphology. In animals, cell
adhesion is mediated by a battery of proteins, including those that give rise to epithelia. Plants, in
contrast, use pectins and, perhaps, hemicelluloses to mediate cell-cell adhesion.
Complex multicellular organisms show not only evidence of cell-cell adhesion but also
intercellular communication and, commonly, tissue differentiation mediated by networks of
regulatory genes.
4. (A) Simple diffusion
Oxygen and carbon dioxide are both small, nonpolar molecules that are able to pass through the
lipid bilayers of the membrane through the simple diffusion process because the plasma
membrane of the capillaries are permeable to these substances..
Measure of poverty (example, the poverty line) and the distribution o.pdf
Measure of poverty (example, the poverty line) and the distribution of income( for example, the
Lorenz curve and the Gini coefficient) are misleading for which of the following two reasons?
First, these measures do not take into account income mobility over time. Second, these
measures ignore the effects of government programs meant to reduce poverty. First, these
measures fail to include the income U.S. citizens earn working for foreign firms that have
operations located in the United States. Second, these measures fail to include income foreign
citizens earn working for U.S. firms that have operations in foreign countries. First, none of
these measures are adjusted for inflation. Second, they do not measure income on a per capita
basis. First, these measures fail to include dividend and interest income earned on stocks and
bonds. Second, these measures fail to include the values of goods and services citizens make for
this own consumptions that are not sold in markets.
Solution
a. First these measures do not take into account income mobility over time. Second, these
measures ignores the effects of government programs meant to reduce poverty..
Many people incorrectly think of evolution as a completely random.pdf
Many people incorrectly think of evolution as a completely random process. Based on the
changes you observed in frequencies of alleles in this simulation, would you say natural selection
is totally predictable, totally unpredictable, or something between? Explain in.
Solution
Generally not.
Transformations, while subject to specific inclinations, are irregular occasions and eccentric. Be
that as it may, one can get a general transformation rate, and with learning of the populace size
and wellness scene, one could likewise for the most part foresee the obsession rate of those
changes.
However, these are all factual estimations, to a substantial degree hopeful ones. Populace sizes
change. Determination weights change, adjusting the wellness scene constantly. Transformation
rates are variable. What\'s more, these progressions can\'t be anticipated.
At a macroevolutionary level, it\'s somewhat more risky, yet again the appropriate response is
no. As an exceptionally straightforward work out, envision constraining canines to live in the
seas for a large number of years. Would you go to a whale-like creature toward the finish of your
analysis? Perhaps, perhaps not: there are numerous possiblities. The primary whales were canine
like creatures, bit by bit adjusting to a more amphibian way of life, and in the long run turned out
to be completely oceanic (see: The Tertiary: Birds, Whales, Humans and Climate Change), then
coevolved with sharks to wind up distinctly the huge creatures of we know today. You couldn\'t
have anticipated any of this 50 million years prior.
One could foresee utilitarian adjustments. Oceanic vertebrates quite often develop a streamlined
shape for the hydrodynamic preferred standpoint: we see this with cetaceans and sharks and
angle, and with the wiped out marine reptiles of the past (mosasaurs, plesiosaurs, and so forth.).
In any case, once more, merged advancement can be truly broad. Flying creatures, bats,
pterosaurs, and creepy crawlies merged on flight, yet all have altogether different systems
empowering flight.
You could foresee that flying life forms will advance \"wings\", however that is a really aimless
articulation, since the definition and structure of a wing changes relying upon the creature; also
that flght can hypothetically be accomplished with different systems, e.g. taking off (creepy
crawlies can do that, yet they have no wings)..
It is simple question.I need Requirements for building a syntax .pdf
It is simple question.
I need \'Requirements for building a syntax analyser tool\'
please answer this for me.
Thanks
Solution
Requirements for Syntax analyzer:
Syntax analyzer checks the syntax with the help of symbol table.Symbol table is generated by
Lexical Analyzer(.l file).
Before syntax analyzer,lexical analysis and semantic analysis takes place.
We need
1)Flex which is lexical analyzer which divides input into tokens
2).l file which is input to flex
3)Yacc which is parser
4).y file input file to yacc
5)Parsing algorithm
6)Language to used for making syntax analyzer c++,java,python
7)Input program to syntax analyzer.

In what way (or ways) is the current Knowledge Revolution a child of the Industrial Revolution?
Is this a new revolution or simply an extension of the 18th-century revolution? Given the history,
is it perhaps more appropriate to call the current revolution a Communications Revolution?
Solution
the present revolution is information oriented revolution, and its a new phase.
why I am saying its a new phase, in this fast generation, every thing is fast and too fast. people
cant live in the same world where they spent on yester day, they always looking for chang and
what more and what next?
the life span of these are much less, with in span of months only these strategies are going to be

2. How does DNA coil or become more compact? Give two reasons why it must be compacted?
3. Explain what crossing over and independent assortment are. Where does each happen in
meiosis?
Solution
1. There are four major types of biomolecules. Carbohydrates, proteins, lipids and nucleic acid.
Out of these, the nucleic acid has the most number of function. Nucleic acid are polymers present
in the living cells and are of two types: Ribonucleic acid (RNA) and Deoxyribonucleic acid
(DNA). DNA carry genes which are responsible for storing and transmitting the hereditary
information from one generation to the next. RNA help in protein formation and also have
functional activity as enzymes.
2. The entire length of DNA in each cell could reach up to 2 meters if measured end to end. The
DNA is coiled with the help of proteins called histones to form nucleosomes which are
compacted together to form chromatin fibre. The reason for it to be compacted : to accomodate
in the small size of the cell which has the size in micro meteres. It is also required to be
specifically coiled which is required to enter cell division.
3. Crossing Over is the process of exchange of genes between two homologous chromosomes
during sexual reproduction. This results in non-identical chromatids called recombinant
chromosomes. It happens in the pachytene stage of Prophase I of meiosis.
Independent assortment is the independent separation of homologous chromosomes. The alleles
of different genes get sorted into gametes randomly. This gives different hereditary traits equal
probability to occur together. in the offspring. It occurs in Metaphase I of meiosis..

Arrange the following enzymes in the order of their action during DNA.pdf
Arrange the following enzymes in the order of their action during DNA replication in E. coli:
DNA polymerase 1, DNA polymerase 3, DNA primate, DNA gyrate and DNA helicase.
Solution
In E.coli, the replication starts at a single origin site (Monocistronic), it is semi-conservative and
consists of two replication forks i.e. leading strand (Continuous DNA replication) and lagging
strand (Okazaki fragments). The replication proceeds sequentially as below:
Therefore, the order of events during DNA replication in E.coli are:
DNA helicase, DNA primate, DNA polymerase 3, DNA polymerase 1, and DNA gyrate.

stands for the rest of the molecule. EXERCISE Based on the olectronegativities of the atoms
involved, predict whether each functional group is polar or nonpolar CHAPTER 2 Water and
Carbon: The Chemical Basis of Life
Solution
Ans. a. Phosphate is an ion. An ion is a chemical species bearing a positive or negative charge.
Note two negative charges on phosphate group.
Ans. b. The weak attractive interaction between a highly electronegative atom (F, O, N) and a H-
atom covalently linked to any such highly electronegative atoms is called hydrogen bond. A
larger difference in the electronegativity of the two atoms in a bond (say, O and H-atoms in a O-
H bond) causes partial charge separation because the electronegative atom pulls the bond
electrons slightly towards itself. Thus, the electronegative atom gets a partial negative charge and
the less electronegative atom gets a partial positive charge. It makes the bond polar (two poles of
charge- a partial negative pole of O-atom, and partial positive charge on H-atom). When a polar
molecule comes in vicinity of another polar group or molecule, the partial positive charge on one
group (molecule) is attracted by partial negative charge on another group (molecule) and vice
versa. This weak attraction is what we call hydrogen bond.
A water (H2O) molecule has both- I. a highly electronegative atom (O- atom), and II. a H-atom
covalently linked to highly electronegative atom.
So, it can form H-bond with a molecule that has-
a highly electronegative atom >> form hydrogen bond with H-atom of water
a H-atom covalently linked to highly electronegative atom >> form hydrogen bond with O-atom
of water
or both A and B
In the given set of groups, all groups (except- thiol, R-SH) have highly electronegative O-atom.
Thus, they all form H-bonds with water.
The S-atoms in thiol group (R-SH) is weakly electronegative. So, the group has low polarity. The
thiol group is also polar (polarity is weaker than that of alcohol) and can form H-bonds with
water, too. However, the resultant H-bonds are much weaker than those formed due to alcohol
(R-OH) groups..
Where is the specific location in an animal where cells are undergoin.pdf
Where is the specific location in an animal where cells are undergoing Meiosis? In a Plant?
Solution
Meiosis is a process by which cell divides. In meiosis cell divides to form four daughter cells,
each with half parental chromosomes i.e half from mother and half from father. So it is evident
that meiosis will takes place in reproductive organs whether it is plants or animals.
In animals meiosis occurs in testes(males) and ovaries(females).
In plants it occurs in anther to form pollen grains and within ovary to form ovules..

states, which are political units that possess some, but not all. of the basic characteristics of a
state. Which of the following is one of them? ]
Solution
1.
To say we are in interesting times would be an understatement, the recent general election has
plunged us further into uncertainty. Putting aside the rights and wrongs of holding the election
and the unfolding political alliances it’s important to remember that on the ground people and
businesses are struggling to keep up with the changes and the potential impact. Most of us get on
with our lives despite the national turmoil. But the effect of that turmoil is to dampen investment
and decision making; which slows growth. Latest research by the Institute of Directors highlights
that 92% of respondents see current uncertainty over the make-up of the government as a
concern. There has been a negative swing of 34 points in confidence in the UK economy from
their last survey in May. This has serious implications for business growth, as how we interpret
and perceive our future, our risk aversion and our need to have good information to make
decisions can stifle our ability to act.
The national situation we are seeing unfold, in terms of lack of clear majority for either side, and
regardless of eventual party outcome, will be a government relying on a brokered deal to get
things through parliament which will exacerbate this uncertainty and the impact of Brexit fears.
So where can we look to for leadership?
A recent blog by the World Economic Forum has highlighted that in many places the nation state
is looking outdated, and even dangerous. Where power is too centralised and focussed on
national interests, policy is disengaged from the local, from the day to day lives of people and
businesses. The populist movement we are seeing globally is a reaction to this; dissatisfaction
with the way countries are governed creates turbulence in the current way of thinking and doing,
and challenges political structures. Shifting of decision making to a more local level eases
tensions as people see change locally and impact can be seen quicker. Cities are therefore
emerging as key leadership nodes, galvanising action and responding to local need. Focussing on
regional economic growth and giving powers and funding to local delivery structures to improve
growth can help alleviate the social and political tensions that have led us down this unfortunate
path to instability.
Half of humanity lives in cities and urbanization is set.

QUESTION 2 Which of the following is not one of the counterproductive.pdf
QUESTION 2 Which of the following is not one of the counterproductive cultural traits that
adversely impact the work climate? O a Hostility to change and a general wariness of new ways
of doing things O b. A highly politicized internal environment O c Company personnel averse to
looking outside the company for best practices O d. Relatively homogeneous top management
team with similar skills O e.A disregard for high ethical standards
Solution
The correct answer is d
Explanation:- Five particularly unhealthy cultural traits are hostility to change, heavily
politicized decision making, insular thinking, unethical and greed driven behaviours and the
presence of incompatible clashing subcultures..
Please answer the following questions only if you know it.Than.pdf
Please answer the following questions only if you know it.
Thank you.
Solution
Answer:
2. (B) Different cells express different set of genes.
Cell differentiation generally depends on changes in gene expression rather than on any changes
in the nucleotide sequence of the cell\'s genome.
3. (A) The type of cell adhesion molecules and cellular junctions.
A fundamental feature of complex multicellular organisms is the molecular adhesion that
governs formation of a distinctive and reproducible multicellular morphology. In animals, cell
adhesion is mediated by a battery of proteins, including those that give rise to epithelia. Plants, in
contrast, use pectins and, perhaps, hemicelluloses to mediate cell-cell adhesion.
Complex multicellular organisms show not only evidence of cell-cell adhesion but also
intercellular communication and, commonly, tissue differentiation mediated by networks of
regulatory genes.
4. (A) Simple diffusion
Oxygen and carbon dioxide are both small, nonpolar molecules that are able to pass through the
lipid bilayers of the membrane through the simple diffusion process because the plasma
membrane of the capillaries are permeable to these substances..
Measure of poverty (example, the poverty line) and the distribution o.pdf
Measure of poverty (example, the poverty line) and the distribution of income( for example, the
Lorenz curve and the Gini coefficient) are misleading for which of the following two reasons?
First, these measures do not take into account income mobility over time. Second, these
measures ignore the effects of government programs meant to reduce poverty. First, these
measures fail to include the income U.S. citizens earn working for foreign firms that have
operations located in the United States. Second, these measures fail to include income foreign
citizens earn working for U.S. firms that have operations in foreign countries. First, none of
these measures are adjusted for inflation. Second, they do not measure income on a per capita
basis. First, these measures fail to include dividend and interest income earned on stocks and
bonds. Second, these measures fail to include the values of goods and services citizens make for
this own consumptions that are not sold in markets.
Solution
a. First these measures do not take into account income mobility over time. Second, these
measures ignores the effects of government programs meant to reduce poverty..
Many people incorrectly think of evolution as a completely random.pdf
Many people incorrectly think of evolution as a completely random process. Based on the
changes you observed in frequencies of alleles in this simulation, would you say natural selection
is totally predictable, totally unpredictable, or something between? Explain in.
Solution
Generally not.
Transformations, while subject to specific inclinations, are irregular occasions and eccentric. Be
that as it may, one can get a general transformation rate, and with learning of the populace size
and wellness scene, one could likewise for the most part foresee the obsession rate of those
changes.
However, these are all factual estimations, to a substantial degree hopeful ones. Populace sizes
change. Determination weights change, adjusting the wellness scene constantly. Transformation
rates are variable. What\'s more, these progressions can\'t be anticipated.
At a macroevolutionary level, it\'s somewhat more risky, yet again the appropriate response is
no. As an exceptionally straightforward work out, envision constraining canines to live in the
seas for a large number of years. Would you go to a whale-like creature toward the finish of your
analysis? Perhaps, perhaps not: there are numerous possiblities. The primary whales were canine
like creatures, bit by bit adjusting to a more amphibian way of life, and in the long run turned out
to be completely oceanic (see: The Tertiary: Birds, Whales, Humans and Climate Change), then
coevolved with sharks to wind up distinctly the huge creatures of we know today. You couldn\'t
have anticipated any of this 50 million years prior.
One could foresee utilitarian adjustments. Oceanic vertebrates quite often develop a streamlined
shape for the hydrodynamic preferred standpoint: we see this with cetaceans and sharks and
angle, and with the wiped out marine reptiles of the past (mosasaurs, plesiosaurs, and so forth.).
In any case, once more, merged advancement can be truly broad. Flying creatures, bats,
pterosaurs, and creepy crawlies merged on flight, yet all have altogether different systems
empowering flight.
You could foresee that flying life forms will advance \"wings\", however that is a really aimless
articulation, since the definition and structure of a wing changes relying upon the creature; also
that flght can hypothetically be accomplished with different systems, e.g. taking off (creepy
crawlies can do that, yet they have no wings)..

Requirements for Syntax analyzer:
Syntax analyzer checks the syntax with the help of symbol table.Symbol table is generated by
Lexical Analyzer(.l file).
Before syntax analyzer,lexical analysis and semantic analysis takes place.
We need
1)Flex which is lexical analyzer which divides input into tokens
2).l file which is input to flex
3)Yacc which is parser
4).y file input file to yacc
5)Parsing algorithm
6)Language to used for making syntax analyzer c++,java,python
7)Input program to syntax analyzer.

2. How does DNA coil or become more compact? Give two reasons why it must be compacted?
3. Explain what crossing over and independent assortment are. Where does each happen in
meiosis?
Solution
1. There are four major types of biomolecules. Carbohydrates, proteins, lipids and nucleic acid.
Out of these, the nucleic acid has the most number of function. Nucleic acid are polymers present
in the living cells and are of two types: Ribonucleic acid (RNA) and Deoxyribonucleic acid
(DNA). DNA carry genes which are responsible for storing and transmitting the hereditary
information from one generation to the next. RNA help in protein formation and also have
functional activity as enzymes.
2. The entire length of DNA in each cell could reach up to 2 meters if measured end to end. The
DNA is coiled with the help of proteins called histones to form nucleosomes which are
compacted together to form chromatin fibre. The reason for it to be compacted : to accomodate
in the small size of the cell which has the size in micro meteres. It is also required to be
specifically coiled which is required to enter cell division.
3. Crossing Over is the process of exchange of genes between two homologous chromosomes
during sexual reproduction. This results in non-identical chromatids called recombinant
chromosomes. It happens in the pachytene stage of Prophase I of meiosis.
Independent assortment is the independent separation of homologous chromosomes. The alleles
of different genes get sorted into gametes randomly. This gives different hereditary traits equal
probability to occur together. in the offspring. It occurs in Metaphase I of meiosis..

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

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.

Given the following information about a continuous-time LTI system (.pdf
- 1. Given the following information about a continuous-time LTI system: (1) it is causal, (2) its system function H(s) is rational and has three poles: -1, -2, and -3, respectively, (3) If x(t) = 5, then y(t) = 0, (4) h(t = 0^+) = 8, and (5) H(s) has a zero at -1/8, determine the exact form of H(s). Solution Ploes are at s=-1,-2,-3 Zero is at s=-1/8 Let H(s)= k*s*(s+1/8)/[(s+1)(s+2)(s+3)] When x(t)=5, then X(s)=5/s Y(s)= H(s)*X(s)= k(s+1/8)/[(s+1)(s+2)(s+3)] = (-k7/16)/(s+1) +(15k/8)/(s+2) -(23k/16)/(s+3) y(t) = 0, Now. From initial value theorem h(0+)= s--> infinity. SH(S) 8 = k Hence. H(s)= 8*s*(s+1/8)/[(s+1)(s+2)(s+3)]
