Solution
Blood capillaries allow(s) for the movement of blood plasma and interstitial fluid into the
lymphatic vessels and trunks. Lymphatic capillaries contain structures that prevent backflow,
called valves. Lymphatic capillaries conduct lymph towards the heart. They transport lymph due
to the pumping action of the skeletal muscle. The lymphatic vessels and trunks include(s) the
lacteals that transport a white, fatty fluid called chyle.
Lymph nodes filter debris and foreign matter from the lymphatic fluid. A lymph node is
surrounded by the fibrous capsule. Beneath the capsule, the node contains specific tissues called
cortex and medulla. It contains fluid filled spaces called the sinuses. It also contains
macrophages suspended on a network of reticular fibers. The lymph nodes are served by fluid-
conducting vessels at the hilum called the afferent lymph vessels..
JAVA.Q4 Create a Time class. This class will represent a point in.pdf
JAVA.
Q4: Create a Time class. This class will represent a point in time, such as a departure time. It
should contain 2 constructors, 2 instance variables (hour and minute), and 10 methods (see
below). All methods but toString should be in terms of the 24 hour format. [30 points]
default constructor: Creates a Time object for 12:00AM.
overloaded constructor: Creates a Time object at a specific hour and minute.
getHour(): Returns an integer representing the hour of the Time object.
getMinute(): Returns an integer representing the minute of the Time object.
addHours(...): Updates the object by moving it forward a number of hours.
addMinute(...): Updates the object by moving it forward a number of minutes. (Hint: Be careful

isSameTime(...): Returns true if this Time object is the same as another Time object.
isLaterThan(...): Returns true if this Time object is later than another Time object.
toString(): Returns a string representing the Time object. Uses 12 hour AM/PM format and pads
minutes to be two digits. See the sample output for an example.
Q5: Create a Flight class that uses the Plane and Time class. This class will represent a flight
between two airports, using a specific Plane, and departing at a specific Time. It should contain a
constructor, 7 instance variables (plane, flight number, cost, departure, duration, source,
destination), and 9 methods (see below). [25 points]
overloaded constructor: Creates a Flight object that is setup up with a Plane, a flight number, a
cost, a departure Time, a duration time, a source Airport, and a destination Airport.
getPlane(): Returns the Plane that operates this flight.
getNumber(): Returns the flight number.

in the case of the Bacillis strain, why would a young culture be used for gram staining while an
old culture is used when spore staining?
Solution
Older clustures donot retain the staining due to weak cell walls hence for old bacillus cultures
endospore staining is done as endospores are more stable structures. The young cultures wil
retain the stain so gram negative staining is done..

How is the mouth of planaria similar to the proboscis of Nemertean.pdf
How is the mouth of planaria similar to the proboscis of Nemertean worms?
How is the mouth of planaria similar to the proboscis of Nemertean worms?
Solution
Both nemerteans and planarians are invertebrates. Planarians are tubellarian flat worms and
nemerteans have been called ribbon worms. Both nemerteans and planarians are acoelomates.
Nemerteans have complete digestive tract and circulatory system like coelomates, but some
similarities exist with planarians. Planarians have been mostly carnivorous and they do not have
digestive tract and circulatory system like nemerteans and other coelomates. Eventhough
nemerteans are the primitive organisms with closed circulatory system with blood vessels
structurally but functionally it looks like planarians. Planarians and nemerteans both have
ciliated epidermis, sense organs such as light sensitive pigment cups. Planarians have single
opening digestive tract with mouth and blind ended flame bulbs for excretion through diffusion.
But in nemerteans, this digestive tube have both ends possessing openings, with mouth for food
taking and blind ended tube develops into end for excretion. Reproduction through fragmentation
could be seen both in planarians and nemerteans. Nemerteans also have the name proboscis
worms because of distinctive feature of proboscis. Nemerteans use the proboscis to capture the
prey, immobilize the prey. Proboscis is a long, hollow, sticky, muscular tube which can be
moved inside out. The proboscis produces toxic chemical to kill the prey. Like the nemerteans
have proboscis to capture the prey, the planarians also have tube like muscular pharynx, which is
the first part of digestive tube of planarians. The planarians like the proboscis of nemerteans can
push its pharynx outward to catch the prey and can take back its pharynx inside once it catches
its prey through the mouth. Thus the pharynx of planarians and proboscis of nemerteans have
similar features..

Solution
Adolescence is a distinct, yet transient, period of development between childhood and adulthood
characterized by increased experimentation and risk taking, heightened sensitivity to peers and
other social influences, and the formation of personal identity. These alterations make this period
a time of vulnerability and adjustment. Major changes in the structure and functioning of the
brain occur at this period and result in cognitive and behavioral development. It contributes to
autonomous decision making and critical thinking contribute to healthy development. Schools,
extracurricular activities, and work settings can provide opportunities for adolescents to learn to
think for themselves, develop self-reliance and self-efficacy, and improve reasoning skills. The
absence of these opportunities in these settings will undermine developmental progress.

Day care centers expose children to a wider variety of germs than th.pdf
Day care centers expose children to a wider variety of germs than the children would be exposed
to if they stayed at home more often. This has the obvious downside of more frequent colds and
other illnesses, but it also serves to challenge the immune system of children at a critical stage in
their development. A study by Gilham et al. (2005) tested whether social activity outside the
house in young children affected their probabilty of later developing the white blood cell disease
acute lymphoblastic leukemia (ALL), the most common cancer of children. They compared 1272
children with acute lymphoblastic leukemia to 6238 children without acute lymphoblastic
leukemia. Of the acute lymphoblastic leukemia kids, 1020 had significant social activity outside
the home (including day care) when younger. Of the kids without acute lymphoblastic leukemia,
5343 had significant social activity outside the home. The rest of the children in both groups
lacked regular contact with children who were not in their immediate surroundings.
a.) Is this an experimental or observational study?
b.) What are the proportions of children with significant social activity in children with and
without acute lymphoblastic leukemia?
c.) What is the odds ratio for acute lymphoblastic leukemia, comparing the groups with and
without significant social activity?
d.) What is the 95% confidence interval for this odds ratio?
e.) Does this confidence interval indicate that the amount of social activity is associated with
acute lymphoblastic leukemia? If so, did the children with more social activity have a higher or
lower occurence of acute lymphoblastic leukemia?
f.) The researchers interpreted their study results in terms of the differing immune system
exposure of the children, but gave several alternative explanations for the pattern. Can you think
of any possible cofounding variables?

Below is a quote from Bobby Kennedy on what the Gross National Produ.pdf
Below is a quote from Bobby Kennedy on what the Gross National Product means and more
importantly what it does not mean.
Too much and too long, we seem to have surrendered community excellence and community
values in the mere accumulation of material things. Our gross national product ... if we should
judge America by that - counts air pollution and cigarette advertising, and ambulances to clear
our highways of carnage. It counts special locks for our doors and the jails for those who break
them. It counts the destruction of our redwoods and the loss of our natural wonder in chaotic
sprawl. It counts napalm and the cost of a nuclear warhead, and armored cars for police who
fight riots in our streets. It counts Whitman\'s rifle and Speck\'s knife, and the television
programs which glorify violence in order to sell toys to our children.
\"Yet the gross national product does not allow for the (1) health of our children, (2) the quality
of their education, or the joy of their play. It does not include the (3) beauty of our poetry or the
strength of our marriages; (4) the intelligence of our public debate or (5) the integrity of our
public officials. It measures neither our (6) wit nor our (7) courage; neither our (8) wisdom nor
our learning; neither our (9) compassion nor our (10) devotion to our country; it measures
everything, in short, except that which makes life worthwhile. And it tells us everything about
America except why we are proud that we are Americans.\"
Kennedy mentions at least 10 things that aren\'t measured by GDP. YOUR task is to argue that
he is wrong. Find a way to prove that we can somewhat account for the factors he mentions in
our GDP.
Solution
As long as these points is not subject to any productive work he is right but if these lap with
productive goods and service programmes they can be included in GDP. For example, if
devotion is spread through tv channels then, people get benefit and trp, satelight rights etc. yield
a return. Hence, it can be possible to include in GDP. Similarly on several grounds we can do
that too for the other items to recorded in the ten points..

Using only the stack abstraction operations defined above, write pseudocode for
an algorithm that determines, using a stack, whether or not the number of closing
parentheses is the same as the number of opening parentheses.
You may assume the existence of a function read(str,ch) that reads the next character
of string str into ch.
You may also assume that you can invoke a function reportFail, that will cause
termination with failure, and similarly, reportSuccess causes termination with a
success indication.
Further, you may also assume that you can call a function newStack(S) to create
a new empty stack S, and eos(str) that returns false when you reach the end of
the string.
Solution
(a) Explain briefly what is meant by the term abstract data type (ADT). Give two
reasons why use of ADTs is good programming practice.
A data type is a collection of values and a set of operations on those values. That collection and
these operations form a mathematical construct that may be implemented with the use of a
particular hardware or software data structure. The term abstract data type (ADT) refers to the
basic mathematical concept that defines the data type. We have discussed four different
implementations of the list data structure.
In case of implementation of the list with the use of an array, the size of the array gives difficulty
if increased.
To avoid this, we allocate memory dynamically for nodes before connecting these nodes with the
help of pointers.
For this purpose, we made a singly linked list and connected it with the next pointer to make a
chain.
Moving forward is easy but going back is a difficult task.
To overcome this problem, we made a doubly linked list using prev andnext pointers. With the
help of these pointers, we can move forward and backward very easily. Now we face another
problem that the prev pointer of first node and the next pointer of the last node are NULL.
Therefore, we have to be careful in case of NULL pointers. To remove the NULL pointers, we
made the circular link list by connecting the first and last node.
The program employing the list data structure is not concerned with its implementation.
We do not care how the list is being implemented whether through an array, singly linked list,
doubly linked list or circular linked list. It has been witnessed that in these four implementations
of the list, the interface remained the same i.e. it implements the same methods like add, get,
next, start a.

12. The white “Spirit” black bear, Ursys anerucabys kermodei, differ.pdf
12. The white “Spirit” black bear, Ursys anerucabys kermodei, differs from the ordinary black
bear by a single amino acid change in the melanocortin 1 receptor gene. In this population, the
gene has two forms (or alleles): the “white: allele b and the “black” allele B. The trait is
recessive: white bears have two copies of the while allele of this gene (bb), whereas a bear is
black if it has one ore two copies of the black allele (Bb or BB). Both colors morphs and all three
genotypes are found together in the bear population of the northwest coast of British Columbia.
If processing the white allele has no effect on growth, survival, reproductive success, or mating
patterns of individual bears, then the frequency of individuals with 0, 1, or 2 copies of the white
allele (b) in the population will follow a binomial distribution. To investigate, Hendrick and
Ritland sampled and genotyped 87 bears from the northwest coast: 42 were BB, 24 were Bb, and
21 were bb. Assume that this is a random sampled of bears.
a. Calculate the fraction of b alleles in the population (remember, each bear has two copies of the
gene).

With respect to the study of law
What is the purpose of discovery?
Who can be deposed? Who must answer interrogatories?
Solution
discovery is the civil process where both parties to a case to be interogated and find collect the
facts or relevant information to the case. it is a civil process where the authorities will personally
interact with both the parties individually and collects the relevant information relates to the
issue. both the parties will rise their voices and they explained their views and perceptions
towards the issue.
the purpose is to konw and identify the truths with pleas and perceptions of the individual related
to the case. here just hearings will happens.
the police parties or official parties will participate in the interogation and questions the victims
and accused people in the case. they will express their views and the reality to the officials..
Why do you need proteins to allow ions to cross the cell membrane an.pdf
Why do you need proteins to allow ions to cross the cell membrane and enter the muscle cell?
Solution
The transfer of ions are required for the conductance of muscle impulse. The proteins are
attached to, or associated with the membrane of a cell or an organelle. Facilitated diffusion is the
spontaneous passage of molecules or ions across a biological membrane passing through specific
transmembrane integral proteins. The use of proteins along with different proteins used in the
transport of ions are listed below:.

a) How does the Edman Degradation method work?
b) What is the correct sequence of your protein?
c) What are alternate ways you could have determined the sequence of your protein?
Solution
Edman degradation is a chemical method used for the sequencing of amino acids in a peptide.
This method is developed by Pehr Edman in 1960. In this method, N-terminal is labeled or
cleaved form the peptide and number of residues are identified
The Edman degradation is a very important reaction for protein sequencing, because it allows the
ordered amino acid composition of a protein to be discovered.
Automated Edman sequencers are now in widespread use, and are able to sequence peptides up
to approximately 50 amino acids long. A reaction scheme for sequencing a protein by the Edman
degradation follows:
1.Break anydisulfide bridgesin the protein with areducing agentlike2-mercaptoethanol.
Aprotecting groupsuch asiodoacetic acidmay be necessary to prevent the bonds from re-forming.
2.Separate and purify the individual chains of the protein complex, if there are more than one.
3.Determine the amino acid composition of each chain.
4.Determine the terminal amino acids of each chain.
5.Break each chain into fragments under 50 amino acids long.
6.Separate and purify the fragments.
7.Determine the sequence of each fragment.
8.Repeat with a different pattern of cleavage.
9.Construct the sequence of the overall protein.
Step – 1: The phenyl isothiocyanate reagent attacks and removes the N-terminal amino acid unit
in the form of a substituted thiohydantoin heterocycle. Characteristic hydantoin derivatives of all
the amino acids have been made and catalogued, so identification of the terminal unit is
accomplished easily by comparison.
Step – 2: The terminal amino group adds to the reactive isothiocyanate function to give a
substituted thiourea. This moiety is conformationally mobile, and the sulfur atom may approach
the carboxyl carbonyl of the N-terminal amino acid.
Step – 3: Anhydrous HCl protonates the amide oxygen atom, activating it to nucleophilic attack
by sulfur. Next, a thiazolinone heterocycle incorporating the N-terminal unit is cleaved, leaving
behind a shorter peptide chain. This heterocyclic ring is unstable and undergoes acid-catalyzed
rearrangement to the isomeric thiohydantoin (in the green shaded box).
Digestion into peptide fragments
Peptides longer than about 50-70 amino acids long cannot be sequenced reliably by the Edman
degradation. Because of this, long protein chains need to be broken up into small fragments that
can then be sequenced individually. Digestion is done either by endopeptidases such as trypsin or
pepsin or by chemical reagents such as cyanogen bromide. Different enzymes give different
cleavage patterns, and the overlap between fragments can be used to construct an overall
sequence.

What type of rock can be dated with radiometric methodsSolution.pdf
What type of rock can be dated with radiometric methods?
Solution
the metamorphic rock and Igneous rock & melt, all are vey slowly cooling and we can measure
radioactivity decay unless or until it cool down below it’s the closure temperature.and more
frequently used radiometric dating technique are depending on breakdown of the Potassium
[40K] to -argon [40Ar]. sharp measurement of 40K to-- 40Ar amount in the igneous rock can tell
you the real amount of time has been passed since this rock crystallized.for the sedimentary
rocks we used Carbon-14 method for young rock( >50,00 years old rock) . This method is
depend upon uptake of the naturally occured radioactive isotope like carbon-14,when living
organism dead than stop accumulating carbon-14 atomes in body,over a time dead living things
incorprated into the sedimentary rock, and geo-scientist calculate radiometric dating by using
this carbon-14 atoms.this method used to measure the age of meteorites, Earth , ages of fossils,
Moon, also early man, ages of mineral deposits, timing of glaciations, recurrence the rates of
volcanic, earthquakes & eruptions Geologists scientist use this radiometric dating method to
estimate or determine that how long ago back rocks were formed, & give information of ages of
the fossils that contained within rocks.
Naturally occurring various radioactive elements in the universe, and we know that Radioactive
atoms are generally inherently unstable ,in radioactive \"large atoms\" decay into the stable small
daughter atoms.in general When the molten rock cool & forming rock are know as igneous rocks
a lot of radioactive atom were trapped inside the rock. than they starte decaying at the perticular
expected rate. By determine the number of unstable atoms are left in rock & compare to the
number of stable molecule of daughter atoms in a rock, geologist can be estimated the amount of
the time is over since the perticularly rock formed.but the Fossils are frequently found in
sedimentary rock,& not in the igneous rock. Sedimentary rocks can be use to dated a
radioactively,carbon, but the problem is carbon decays vey quickly, this method can only work
for the younger rocks age about 50 thousand years. So that in order to measure or date rock &
older fossils, geologist scientists used layer of the volcanic ash & igneous rock below and above
the fossil.geo- Scientists date the igneous rock by using elements which slow to decay, like
uranium & potassium..

SUPER FORTRESS:
The Boeing B-29 Superfortress is a four-engine propeller-driven heavy bomber designed by
Boeing which was flown primarily by the United States during World War II and the Korean
War. It was one of the largest aircraft operational during World War II and featured state of the
art technology. It was the single most expensive weapons project undertaken by the United
States in World War II, exceeding the cost of the Manhattan Project by between 1 and 1.7 billion
dollars. It featured apressurized cabin, all dual wheeled, tricycle landing gears, and a remote,
computer-controlled fire-control system that directed four machine gun turrets that could be
operated by a single gunner and a fire-control officer. A manned tail gun installation was semi-
remote. The name “Superfortress” continued the pattern Boeing started with its well-known
predecessor, the B-17 Flying Fortress. Designed for the high-altitude strategic bomber role, the
B-29 also excelled in low-altitude nighttimeincendiary bombing missions. One of the B-29’s
final roles during World War II was carrying out the atomic bomb attacks on Hiroshima and
Nagasaki.
Due to the B-29’s highly advanced design, unlike many other World War II-era bombers, the
Superfortress remained in service long after the war ended, with a few even being employed as
flying television transmitters for the Stratovisioncompany. The B-29 served in various roles
throughout the 1950s. The Royal Air Force flew the B-29 as the Washington until phasing out
the type in 1954. The Soviet Union produced an unlicensed reverse-engineered copy as the
Tupolev Tu-4. The B-29 was the progenitor of a series of Boeing-built bombers, transports,
tankers, reconnaissance aircraft and trainers including the B-50 Superfortress (the first aircraft to
fly around the world non-stop) which was essentially a re-engined B-29. The type was finally
retired in the early 1960s. The B-29 production total was 3,970 aircraft. Dozens of B-29s remain
as static displays but only two examples, Fifi and DOC, have been restored to flying status; with
Doc flying again for the first time from McConnell AFB on July 17, 2016.
FLYING FORTRESS:
The Boeing B-17 Flying Fortress is a four-engine heavy bomber developed in the 1930s for the
United States Army Air Corps (USAAC). Competing against Douglas and Martin for a contract
to build 200 bombers, the Boeing entry outperformed both competitors and exceeded the air
corps\' performance specifications. Although Boeing lost the contract because the prototype
crashed, the air corps ordered 13 more B-17s for further evaluation. From its introduction in
1938, the B-17 Flying Fortress evolved through numerous design advances.[5][6]
The B-17 was primarily employed by the United State.

\"Using netbeans java\"
The purpose of this exercise is to effectively demonstrate, that if an external code receives the
address of an instance of a class, it can change the state of the object of that class, even it is
against the intentions of the programmer who implemented the class. In order to prevent such an
intrusion, accessors of reference type fields should not return the field itself, but rather a copy of
it.
1. The ArrayPractice class has two private data fields, both are arrays. Declare the fields as
-- an array to store integer numbers of type int named numbers
-- an array to store Rectangle references (type is Rectangle) named boxes
\"Do not instantiate the fields at the declaration!\"
2. Each field has an associated accessor method as usual
3. There is a second accessor method associated to boxes named as getCopyOfBoxes, see the
definition later.
4. Define a method named loadArrays( ). The method is void and takes no parameter. The
method assigns the entries of the integer array and those of the Rectangle array such that for each
array it
--runs a for loop to the length of the array
--entries of the int array assigned a random integer between 1 and 100
--each entry of the Rectangle array is assigned a new Rectangle object with random integer
length and width values. Select the integers again between 1 and 100. Note that the individual
Rectangle objects do not have names.
5. The class has a default constructor and an initializer constructor such that it takes one
parameter, an int type value named size. The constructor
-instantiates the fields numbers and boxes such that the array length is size for both
-calls the loadArray() method
6. Define a method named copyNumbers( ). The method takes no parameter and returns an array
integers, a copy of the numbers field. In the method declare and instantiate an array (a local
variable) named say, temp, with the same type and to the same length as those of the field. The
method runs a for loop to load the temp array such that it assigns each temp entry the
corresponding numbers entry index-by-index. The method returns temp.
7. Define a method named copyBoxes( ). This method is entirely analogous to the previous
method copyNumbers except in the for loop of we do NOT assign boxes[k] to temp[k], but
rather a new Rectangle which is a copy of the boxes[k]. This copy must be instantiated by the
copy constructor you added to the Rectangle class in Exercise 1 above. That is, the value
assigned to temp[k] will be new Rectangle(boxes[k])
8. Complete the definition of the second accessor method getCopyOfBoxes() mentioned above
so as to return copyBoxes( ) rather than boxes itself.

Day care centers expose children to a wider variety of germs than th.pdf
Day care centers expose children to a wider variety of germs than the children would be exposed
to if they stayed at home more often. This has the obvious downside of more frequent colds and
other illnesses, but it also serves to challenge the immune system of children at a critical stage in
their development. A study by Gilham et al. (2005) tested whether social activity outside the
house in young children affected their probabilty of later developing the white blood cell disease
acute lymphoblastic leukemia (ALL), the most common cancer of children. They compared 1272
children with acute lymphoblastic leukemia to 6238 children without acute lymphoblastic
leukemia. Of the acute lymphoblastic leukemia kids, 1020 had significant social activity outside
the home (including day care) when younger. Of the kids without acute lymphoblastic leukemia,
5343 had significant social activity outside the home. The rest of the children in both groups
lacked regular contact with children who were not in their immediate surroundings.
a.) Is this an experimental or observational study?
b.) What are the proportions of children with significant social activity in children with and
without acute lymphoblastic leukemia?
c.) What is the odds ratio for acute lymphoblastic leukemia, comparing the groups with and
without significant social activity?
d.) What is the 95% confidence interval for this odds ratio?
e.) Does this confidence interval indicate that the amount of social activity is associated with
acute lymphoblastic leukemia? If so, did the children with more social activity have a higher or
lower occurence of acute lymphoblastic leukemia?
f.) The researchers interpreted their study results in terms of the differing immune system
exposure of the children, but gave several alternative explanations for the pattern. Can you think
of any possible cofounding variables?

Below is a quote from Bobby Kennedy on what the Gross National Produ.pdf
Below is a quote from Bobby Kennedy on what the Gross National Product means and more
importantly what it does not mean.
Too much and too long, we seem to have surrendered community excellence and community
values in the mere accumulation of material things. Our gross national product ... if we should
judge America by that - counts air pollution and cigarette advertising, and ambulances to clear
our highways of carnage. It counts special locks for our doors and the jails for those who break
them. It counts the destruction of our redwoods and the loss of our natural wonder in chaotic
sprawl. It counts napalm and the cost of a nuclear warhead, and armored cars for police who
fight riots in our streets. It counts Whitman\'s rifle and Speck\'s knife, and the television
programs which glorify violence in order to sell toys to our children.
\"Yet the gross national product does not allow for the (1) health of our children, (2) the quality
of their education, or the joy of their play. It does not include the (3) beauty of our poetry or the
strength of our marriages; (4) the intelligence of our public debate or (5) the integrity of our
public officials. It measures neither our (6) wit nor our (7) courage; neither our (8) wisdom nor
our learning; neither our (9) compassion nor our (10) devotion to our country; it measures
everything, in short, except that which makes life worthwhile. And it tells us everything about
America except why we are proud that we are Americans.\"
Kennedy mentions at least 10 things that aren\'t measured by GDP. YOUR task is to argue that
he is wrong. Find a way to prove that we can somewhat account for the factors he mentions in
our GDP.
Solution
As long as these points is not subject to any productive work he is right but if these lap with
productive goods and service programmes they can be included in GDP. For example, if
devotion is spread through tv channels then, people get benefit and trp, satelight rights etc. yield
a return. Hence, it can be possible to include in GDP. Similarly on several grounds we can do
that too for the other items to recorded in the ten points..

Solution
(a) Explain briefly what is meant by the term abstract data type (ADT). Give two
reasons why use of ADTs is good programming practice.
A data type is a collection of values and a set of operations on those values. That collection and
these operations form a mathematical construct that may be implemented with the use of a
particular hardware or software data structure. The term abstract data type (ADT) refers to the
basic mathematical concept that defines the data type. We have discussed four different
implementations of the list data structure.
In case of implementation of the list with the use of an array, the size of the array gives difficulty
if increased.
To avoid this, we allocate memory dynamically for nodes before connecting these nodes with the
help of pointers.
For this purpose, we made a singly linked list and connected it with the next pointer to make a
chain.
Moving forward is easy but going back is a difficult task.
To overcome this problem, we made a doubly linked list using prev andnext pointers. With the
help of these pointers, we can move forward and backward very easily. Now we face another
problem that the prev pointer of first node and the next pointer of the last node are NULL.
Therefore, we have to be careful in case of NULL pointers. To remove the NULL pointers, we
made the circular link list by connecting the first and last node.
The program employing the list data structure is not concerned with its implementation.
We do not care how the list is being implemented whether through an array, singly linked list,
doubly linked list or circular linked list. It has been witnessed that in these four implementations
of the list, the interface remained the same i.e. it implements the same methods like add, get,
next, start a.

12. The white “Spirit” black bear, Ursys anerucabys kermodei, differ.pdf
12. The white “Spirit” black bear, Ursys anerucabys kermodei, differs from the ordinary black
bear by a single amino acid change in the melanocortin 1 receptor gene. In this population, the
gene has two forms (or alleles): the “white: allele b and the “black” allele B. The trait is
recessive: white bears have two copies of the while allele of this gene (bb), whereas a bear is
black if it has one ore two copies of the black allele (Bb or BB). Both colors morphs and all three
genotypes are found together in the bear population of the northwest coast of British Columbia.
If processing the white allele has no effect on growth, survival, reproductive success, or mating
patterns of individual bears, then the frequency of individuals with 0, 1, or 2 copies of the white
allele (b) in the population will follow a binomial distribution. To investigate, Hendrick and
Ritland sampled and genotyped 87 bears from the northwest coast: 42 were BB, 24 were Bb, and
21 were bb. Assume that this is a random sampled of bears.
a. Calculate the fraction of b alleles in the population (remember, each bear has two copies of the
gene).
proportion from the data
b. With your estimate of the fraction of b alleles, and assuming a binomial distribution, calculate
the expected frequency of bears with 0, 1, and 2 copies.
c. Compare the observed and expected frequencies in a graph. Describe how they differ.

With respect to the study of law
What is the purpose of discovery?
Who can be deposed? Who must answer interrogatories?
Solution
discovery is the civil process where both parties to a case to be interogated and find collect the
facts or relevant information to the case. it is a civil process where the authorities will personally
interact with both the parties individually and collects the relevant information relates to the
issue. both the parties will rise their voices and they explained their views and perceptions
towards the issue.
the purpose is to konw and identify the truths with pleas and perceptions of the individual related
to the case. here just hearings will happens.
the police parties or official parties will participate in the interogation and questions the victims
and accused people in the case. they will express their views and the reality to the officials..
Why do you need proteins to allow ions to cross the cell membrane an.pdf
Why do you need proteins to allow ions to cross the cell membrane and enter the muscle cell?
Solution
The transfer of ions are required for the conductance of muscle impulse. The proteins are
attached to, or associated with the membrane of a cell or an organelle. Facilitated diffusion is the
spontaneous passage of molecules or ions across a biological membrane passing through specific
transmembrane integral proteins. The use of proteins along with different proteins used in the
transport of ions are listed below:.

a) How does the Edman Degradation method work?
b) What is the correct sequence of your protein?
c) What are alternate ways you could have determined the sequence of your protein?
Solution
Edman degradation is a chemical method used for the sequencing of amino acids in a peptide.
This method is developed by Pehr Edman in 1960. In this method, N-terminal is labeled or
cleaved form the peptide and number of residues are identified
The Edman degradation is a very important reaction for protein sequencing, because it allows the
ordered amino acid composition of a protein to be discovered.
Automated Edman sequencers are now in widespread use, and are able to sequence peptides up
to approximately 50 amino acids long. A reaction scheme for sequencing a protein by the Edman
degradation follows:
1.Break anydisulfide bridgesin the protein with areducing agentlike2-mercaptoethanol.
Aprotecting groupsuch asiodoacetic acidmay be necessary to prevent the bonds from re-forming.
2.Separate and purify the individual chains of the protein complex, if there are more than one.
3.Determine the amino acid composition of each chain.
4.Determine the terminal amino acids of each chain.
5.Break each chain into fragments under 50 amino acids long.
6.Separate and purify the fragments.
7.Determine the sequence of each fragment.
8.Repeat with a different pattern of cleavage.
9.Construct the sequence of the overall protein.
Step – 1: The phenyl isothiocyanate reagent attacks and removes the N-terminal amino acid unit
in the form of a substituted thiohydantoin heterocycle. Characteristic hydantoin derivatives of all
the amino acids have been made and catalogued, so identification of the terminal unit is
accomplished easily by comparison.
Step – 2: The terminal amino group adds to the reactive isothiocyanate function to give a
substituted thiourea. This moiety is conformationally mobile, and the sulfur atom may approach
the carboxyl carbonyl of the N-terminal amino acid.
Step – 3: Anhydrous HCl protonates the amide oxygen atom, activating it to nucleophilic attack
by sulfur. Next, a thiazolinone heterocycle incorporating the N-terminal unit is cleaved, leaving
behind a shorter peptide chain. This heterocyclic ring is unstable and undergoes acid-catalyzed
rearrangement to the isomeric thiohydantoin (in the green shaded box).
Digestion into peptide fragments
Peptides longer than about 50-70 amino acids long cannot be sequenced reliably by the Edman
degradation. Because of this, long protein chains need to be broken up into small fragments that
can then be sequenced individually. Digestion is done either by endopeptidases such as trypsin or
pepsin or by chemical reagents such as cyanogen bromide. Different enzymes give different
cleavage patterns, and the overlap between fragments can be used to construct an overall
sequence.

What type of rock can be dated with radiometric methodsSolution.pdf
What type of rock can be dated with radiometric methods?
Solution
the metamorphic rock and Igneous rock & melt, all are vey slowly cooling and we can measure
radioactivity decay unless or until it cool down below it’s the closure temperature.and more
frequently used radiometric dating technique are depending on breakdown of the Potassium
[40K] to -argon [40Ar]. sharp measurement of 40K to-- 40Ar amount in the igneous rock can tell
you the real amount of time has been passed since this rock crystallized.for the sedimentary
rocks we used Carbon-14 method for young rock( >50,00 years old rock) . This method is
depend upon uptake of the naturally occured radioactive isotope like carbon-14,when living
organism dead than stop accumulating carbon-14 atomes in body,over a time dead living things
incorprated into the sedimentary rock, and geo-scientist calculate radiometric dating by using
this carbon-14 atoms.this method used to measure the age of meteorites, Earth , ages of fossils,
Moon, also early man, ages of mineral deposits, timing of glaciations, recurrence the rates of
volcanic, earthquakes & eruptions Geologists scientist use this radiometric dating method to
estimate or determine that how long ago back rocks were formed, & give information of ages of
the fossils that contained within rocks.
Naturally occurring various radioactive elements in the universe, and we know that Radioactive
atoms are generally inherently unstable ,in radioactive \"large atoms\" decay into the stable small
daughter atoms.in general When the molten rock cool & forming rock are know as igneous rocks
a lot of radioactive atom were trapped inside the rock. than they starte decaying at the perticular
expected rate. By determine the number of unstable atoms are left in rock & compare to the
number of stable molecule of daughter atoms in a rock, geologist can be estimated the amount of
the time is over since the perticularly rock formed.but the Fossils are frequently found in
sedimentary rock,& not in the igneous rock. Sedimentary rocks can be use to dated a
radioactively,carbon, but the problem is carbon decays vey quickly, this method can only work
for the younger rocks age about 50 thousand years. So that in order to measure or date rock &
older fossils, geologist scientists used layer of the volcanic ash & igneous rock below and above
the fossil.geo- Scientists date the igneous rock by using elements which slow to decay, like
uranium & potassium..

SUPER FORTRESS:
The Boeing B-29 Superfortress is a four-engine propeller-driven heavy bomber designed by
Boeing which was flown primarily by the United States during World War II and the Korean
War. It was one of the largest aircraft operational during World War II and featured state of the
art technology. It was the single most expensive weapons project undertaken by the United
States in World War II, exceeding the cost of the Manhattan Project by between 1 and 1.7 billion
dollars. It featured apressurized cabin, all dual wheeled, tricycle landing gears, and a remote,
computer-controlled fire-control system that directed four machine gun turrets that could be
operated by a single gunner and a fire-control officer. A manned tail gun installation was semi-
remote. The name “Superfortress” continued the pattern Boeing started with its well-known
predecessor, the B-17 Flying Fortress. Designed for the high-altitude strategic bomber role, the
B-29 also excelled in low-altitude nighttimeincendiary bombing missions. One of the B-29’s
final roles during World War II was carrying out the atomic bomb attacks on Hiroshima and
Nagasaki.
Due to the B-29’s highly advanced design, unlike many other World War II-era bombers, the
Superfortress remained in service long after the war ended, with a few even being employed as
flying television transmitters for the Stratovisioncompany. The B-29 served in various roles
throughout the 1950s. The Royal Air Force flew the B-29 as the Washington until phasing out
the type in 1954. The Soviet Union produced an unlicensed reverse-engineered copy as the
Tupolev Tu-4. The B-29 was the progenitor of a series of Boeing-built bombers, transports,
tankers, reconnaissance aircraft and trainers including the B-50 Superfortress (the first aircraft to
fly around the world non-stop) which was essentially a re-engined B-29. The type was finally
retired in the early 1960s. The B-29 production total was 3,970 aircraft. Dozens of B-29s remain
as static displays but only two examples, Fifi and DOC, have been restored to flying status; with
Doc flying again for the first time from McConnell AFB on July 17, 2016.
FLYING FORTRESS:
The Boeing B-17 Flying Fortress is a four-engine heavy bomber developed in the 1930s for the
United States Army Air Corps (USAAC). Competing against Douglas and Martin for a contract
to build 200 bombers, the Boeing entry outperformed both competitors and exceeded the air
corps\' performance specifications. Although Boeing lost the contract because the prototype
crashed, the air corps ordered 13 more B-17s for further evaluation. From its introduction in
1938, the B-17 Flying Fortress evolved through numerous design advances.[5][6]
The B-17 was primarily employed by the United State.

\"Using netbeans java\"
The purpose of this exercise is to effectively demonstrate, that if an external code receives the
address of an instance of a class, it can change the state of the object of that class, even it is
against the intentions of the programmer who implemented the class. In order to prevent such an
intrusion, accessors of reference type fields should not return the field itself, but rather a copy of
it.
1. The ArrayPractice class has two private data fields, both are arrays. Declare the fields as
-- an array to store integer numbers of type int named numbers
-- an array to store Rectangle references (type is Rectangle) named boxes
\"Do not instantiate the fields at the declaration!\"
2. Each field has an associated accessor method as usual
3. There is a second accessor method associated to boxes named as getCopyOfBoxes, see the
definition later.
4. Define a method named loadArrays( ). The method is void and takes no parameter. The
method assigns the entries of the integer array and those of the Rectangle array such that for each
array it
--runs a for loop to the length of the array
--entries of the int array assigned a random integer between 1 and 100
--each entry of the Rectangle array is assigned a new Rectangle object with random integer
length and width values. Select the integers again between 1 and 100. Note that the individual
Rectangle objects do not have names.
5. The class has a default constructor and an initializer constructor such that it takes one
parameter, an int type value named size. The constructor
-instantiates the fields numbers and boxes such that the array length is size for both
-calls the loadArray() method
6. Define a method named copyNumbers( ). The method takes no parameter and returns an array
integers, a copy of the numbers field. In the method declare and instantiate an array (a local
variable) named say, temp, with the same type and to the same length as those of the field. The
method runs a for loop to load the temp array such that it assigns each temp entry the
corresponding numbers entry index-by-index. The method returns temp.
7. Define a method named copyBoxes( ). This method is entirely analogous to the previous
method copyNumbers except in the for loop of we do NOT assign boxes[k] to temp[k], but
rather a new Rectangle which is a copy of the boxes[k]. This copy must be instantiated by the
copy constructor you added to the Rectangle class in Exercise 1 above. That is, the value
assigned to temp[k] will be new Rectangle(boxes[k])
8. Complete the definition of the second accessor method getCopyOfBoxes() mentioned above
so as to return copyBoxes( ) rather than boxes itself.

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

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.
