Explain why membranes are semifluid and describe how membrane compos.pdf
Explain why membranes are semifluid and describe how membrane composition can affect
fluidity? What are other factors that affect Fluidity?
Solution
Membranes are composed of both type of fatty acid(unsaturated and saturated) unsaturated fatty
acid always tend to be liquid state, where as saturated fatty acid tend to take a gel state, and the
proteins in plasma membrane are also water soluble, so membrane takes a gel like semi fluid
state always & its also important for membrane as membrane fluidity confers the transportation
of several molecules important for cell. Semifluid nature also helps the cell to be more elastic
type.
if membrane has a high percentage of unsaturated fatty acids then it takes a liquid or fluidic stage
and if membrane has a high percentage of saturated fatty acid then it takes a semi solid gel like
structure. Cholesterol in the membrane makes a membrane less fluid gel like substance.The other
factors that affects fluidity are 1. Temperature 2.polarity 3.pH 4.protein present in the membrane.

A slinky can demonstrate both a transverse and longitudinal wave. Ho.pdf
A slinky can demonstrate both a transverse and longitudinal wave. How?
Solution
If a slinky is stretched out from end to end, a wave can be introduced into the slinky by either
vibrating the first coil up and down vertically or back and forth horizontally. A wave will
subsequently be seen traveling from one end of the slinky to the other. As the wave moves along
the slinky, each individual coil is seen to move out of place and then return to its original
position. The coils always move in the same direction that the first coil was vibrated. A
continued vibration of the first coil results in a continued back and forth motion of the other
coils. If looked at closely, one notices that the wave does not stop when it reaches the end of the
slinky; rather it seems to bounce off the end and head back from where it started.
A transverse wave is a wave in which particles of the medium move in a direction perpendicular
to the direction that the wave moves. Suppose that a slinky is stretched out in a horizontal
direction across the classroom and that a pulse is introduced into the slinky on the left end by
vibrating the first coil up and down. Energy will begin to be transported through the slinky from
left to right. As the energy is transported from left to right, the individual coils of the medium
will be displaced upwards and downwards. In this case, the particles of the medium move
perpendicular to the direction that the pulse moves.
A longitudinal wave is a wave in which particles of the medium move in a direction parallel to
the direction that the wave moves. Suppose that a slinky is stretched out in a horizontal direction
across the classroom and that a pulse is introduced into the slinky on the left end by vibrating the
first coil left and right. Energy will begin to be transported through the slinky from left to right.
As the energy is transported from left to right, the individual coils of the medium will be
displaced leftwards and rightwards. In this case, the particles of the medium move parallel to the
direction that the pulse moves..

Consider the TCP multiple acknowledgement scheme. A base station (BS.pdf
Consider the TCP multiple acknowledgement scheme. A base station (BS) may receive an out of
sequence packet that was buffered at an earlier point in time. How can such a situation arise in
the network? (3 marks) Actions taken by the BS will depend upon the sequence number of the
received packet from the sender (in the wired segment) and sequence number of the last
unacknowledged packet (at the BS). Based on these sequence number values, explain the
different responses the BS can generate to bring the system to a consistent state. (6 marks)
Solution
Here TCP may be defined as the transmission control protocol where each nodes has to depend
on acknowledgment and sequence number from sender to receiver. Basically as we look at the
OSI model this TCP protocol lies in transport layer of OSI model, which is connection oriented
protocol. In this type of connection every data is divided into segments and each segment is
given a sequence number and on that basis data is being completely sent one by one in segments.
Since this type of protocol waits for the acknowledgment from the receiver so it is considered a
slow connection. But has got capability of fast data recovery and error control as well flow
control and congestion control.
In multiple acknowledgments we can denote that RTT would be for end to end round trip time
and similarly RTT (w) would be denoted as the round trip for base station and wireless node.
Here sender tries to re send the segments after waiting some time from end to end
acknowledgement until it receives an acknowledgment from the receiver thus establishes a
proper connection when a sender holds a ACK from the base station, then apparently sender gets
to know that base station has received the packets until S-1 but has got a difficulty to send it to
the wireless nodes/hosts, since it has not received the ACK from the wireless host even waiting
for some time.
When a base station receives a packet from the node sender, it keeps a timer and then again
sends to the sender. If suppose the timer get over from the base station it then sends ACKp
towards the sender and then next sequence number is being attached and sends back to the sender
which further sends to the wireless hosts.
Similarly if base station receives a packet which is out of sequence then it will send this packet to
the wireless node and if it doesn’t get received within time given then, then it will send early
packet to the sender by the base station upon which it sends ACKp to the sender..
3. A surface water has pH 7.2. What type of alkalinity should we expe.pdf
3. A surface water has pH 7.2. What type of alkalinity should we expect in this water? If pH 9.0,
what type of alkalinity should we expect?
Solution
From pH 14 to 10.2 there will be only hydroxide and carbonate alkalinity. When pH reaches 10.2
and below all hydroxide disappear.
From 10.2 to 8.3: No hydroxide alkalinity exist. Carbonate starts conversion to bicarbonate.
Hence both carbonate and bi carbonates exist. But by the end of pH 8.3 all the caronate will be
completely gets converted to bicarbonate. Hence no carbonate and no hydroxide below pH 8.3.
pH 8.3 to 4.3: only bicarbonate ion exists.
Answer:
Water having pH 7.2 will have only bicarbonate alkalinity.
Water having pH 9 will have both carbonate and bicarbonate alkalinity..
Assume you found a new worm species while working at Friday Harbor M.pdf
Assume you found a new worm species while working at Friday Harbor Marine Lab last
summer. It has some cells at the vegetal pole that form right after cleavage, then move into the
embryo. If you cut off the cells, the animals that developed were sterile. Using your knowledge
gained from lecture, what can you tell me about what these cells might be doing? What
experiments might you do to test your hypothesis?
What are enhancers? How do they function to promote gene expression, especially since they
may be some distance from the transcribed gene?? Do enhancers interact with promoters and
basal transcription factors?
Solution
Lower invertebrates (including worms) develop via autonomous specification. In this type of
specification, fate of cells is decided in early blastula stage. If in early stages, any cell is lost,
then the organ/cell part/body part destined to be formed from that lost cell will not be formed.
Such pattern of cell division and cleavage in early stages is known as mosaic division.
In the above case, the new worm species isolated is a lower invertebrate. And the lost cells, are
those which were responsible for formation of gonads. Now, because of autonomous
specification, loss of cells, responsible for development of gonads leads to formation of sterile
worms.
To test the hypothesis, you can take a control animal (worm) without the \"cut off cells” and a
test animal with cells cut out.
Enhancers are short regions in DNA, which bind to transcription factors. Transcription factors in
turn bind to promoter. So, with the help of enhancer binding of promoter, RNA polymerase and
transcription factors is speeded up. Overall the process of transcription is enhanced.
Enhancers can be located anywhere in the DNA. They may far away from the gene; or may be
present in some other gene; or can be present in the exon itself. They can be reversed also.
Enhancer of one gene can affect the transcription of another gene. There overall function is to
recruit RNA polymerase to the promoter. This can be done by chromatin modeling in several
ways (For detailed description of this part, please post separately).
No, enhancers do not interact directly with promoters and BTFs. They interact with other
transcription factors which in turn interact with a \'Transcription activator protein\'; which in
turn, binds to promoter..

You are responsible for convening a major event in which senior offi.pdf
You are responsible for convening a major event in which senior officials from several state
governments will try to come to an agreement on environmental issues. It is well known that
some officials posture so that they appear superior, whereas others are highly motivated to solve
the environmental problems that cross adjacent states. What team decision-making problems are
likely to be apparent in this government forum and what actions can you take to minimize these
problems?
Solution
I would consider the following team decision -making problems in this example:
1. Not fully aware about the current situation : State the current situtation and enlist the gravity
of the current issues being faced by several state governments: This is important to then arive at
a common goal or analyze the impact of various issues on the individual state governements and
the center, This should be the starting point for all state Governements considering that all of
them will be acing several environmental issues with difference and variability in severeity. For
eg: Noise Pollution, Ozone depletion, impact of radiation, Air and Sea Pollution, Diesease due to
environmental issues. Actions that I would take to minimize this problem: Ensure that the state
governments have complete facts and data and inputs of environmentalists, citizen groups on the
current situation and have it documented.
2. Goals are unclear : Each State must agree on the actions items to be achieved by setting
CLEAR goals. If the group begins to work on a solution before fully comprehending their goals,
the final result may not be the best fit for them. Actions that I would take to minimize this
problem: Each State can have a sub-goal with one common goal for the center. This will ensure
that there is enough motivation for each state to implement the agreed action items.
3: Absence of Complete and correct information: Another important aspect of team decision
making is having correct information about the given situation. Not only should all of the
information presented to the group be factually correct, but it should also be time relevant. If the
team attempts to arrive at a decision with too little or incorrect information, the final result will
likely result in an error and cost the governments time and money.Actions that I would take to
minimize this problem: Validate the information presented by the states and ensure that it is pre-
validated by neutral organisations.
4. Incorrect information about Data Available: The State Governments needs to involve
environmentalists and statisticians to interpret the data that is available to complete the study of
the current situation. As mentioned previously, it is essential that a team have all of the correct
information before attempting to come to a decision. However, even if the group has all of the
correct information the end result can still have flaws. Group members need to carefully interpret
and understand all of the data that they have to .

What happens to a B-mode image without post processing filtersWha.pdf
What happens to a B-mode image without post processing filters?
What happens to a B-mode image without envelope detection?
Solution
1) It is often necessary to do a wide variety of post processing to form the best quality ultrasound
images before displaying the information for human observation. This post processing might
include various techniques and the order depend on the system configuration. The key task
involved in post processing is conversion of raw data into displayed data.
>> For speckle reduction, various methods such as wavelet decomposition, anisotropic fitering
and bilateral filtering can be applied. These techniques follow spatial compounding which is a
multi imaging method where, by combining views of the same object from different angles, each
having an uncorrelated speckle realization, the resulting image will have significantly reduced
speckle.
>> Lowpass and Highpass fitering techniques are apllied for obtaining smoothening and for
higlighting the edges respectively.
>> Histogram eualization is typically used to improve image contrast and quality, and involves
doing a gray level transformation to obtain a uniform histogram from images with un-balanced
histograms.
To conclude, the B-mode imaging without these post processing techniques makes impossible
human intrepretation and observation.
2) The amplitude of the reflected sound waves forms the basis for the ultrasound image at its
focal point location. Envelope detection along with log compression is used to detect the peaks in
the received signal and to reduce the dynamic range of the received signals for efficient display.
Once all of the amplitudes for all of the focal points have been detected, they can be displayed
for analysis by the doctor or technician.
The B-mode imaging without envelope detection allows all reflected ultrasound waves for post
procesing that leads to a reconstruction a noisy image which is useless for diagnosis..

these species? The phylogeny in this figure shows the evolution of visual opsins in tetrapods.
Each colored triangle represents a different opsin. Which of the following accurately describes
the opsins in these species? A AAA AAAA A A AA AAA AAA Squamate reptiles New World
A opsin gain A opsin loss Tetrapod Click to view larger im O The green opsin is a
synapomorphy in rodents and New World primates, and the light blue opsin is a
symplesiomorphy in baboons and humans. O b. The light blue opsin is a synapomorphy in
squamate reptiles and birds, and the green opsin is an ancestral trait. O c The purple opsl in is an
analogous trait, and the green opsin is a homologous trait. O d The green opsin is a
synapomorphy in baboons and humans, and the light blue opsin is symplesiomorphy in squamate
reptiles and birds.
Solution
synapomorphy means a character that is present in an ancestral species and then it is shared by
one or more descendants, symplesiomorphy means that it is a shared primitive trait.
since we can see that the green opsin is first present in the ancestor the tetrapod and then gets
transferred to only baboons and humans it is derived, also we see that light blue opsin is
transferred to the reptiles and the birds from the tetrapod ancestor.
therefore the correct option should be:
the green opsin is a synapomorphy in baboons and humans, and the light blue opsin is
symplesiomorphy in squamate reptiles and birds..

1. How does the temperature influence the plasticity and elasticity .pdf
1. How does the temperature influence the plasticity and elasticity of materials?
2. What does it mean by ideal materials? And which real material is close to the definition of
ideal materials?
3. What are the imperfections found I solid materials? Describe them.
Please answer.
Solution
1)
The effect of temperature on elasticity is difficult to isolate, because there are numerous factors
affecting it. For instance, the bulk modulus of a material is dependent on the form of its lattice,
its behavior under expansion, as well as the vibrations of the molecules, all of which are
dependent on temperature.
Inelastic deformations of rocks and concrete are primarily caused by the formation of
microcracks and sliding motions relative to these cracks. At high temperatures and pressures,
plastic behavior can also be affected by the motion of dislocations in individual grains in the
microstructure
2)
Endless supply and close available source
Cheap to produce
Energy efficient
Appropriately strong, stiff, and temperature stable
Lightweight
Corrosion resistant
Produces no harmful effects (for environment or people)
Biodegradable or completely recyclable
It can be a difficult and complex process to find the ideal material for a specific product or
application. This process is called the material selection.
3) Imperfections in Solids:
Materials are often stronger when they have defects. The study of defects is divided according to
their dimension:
0D (zero dimension) – point defects: vacancies and interstitials. Impurities.
1D – linear defects: dislocations (edge, screw, mixed)
2D – grain boundaries, surfaces.
3D – extended defects: pores, cracks.
0D (Zero dimension):
A vacancy is a lattice position that is vacant because the atom is missing. It is created when the
solid is formed. There are other ways of making a vacancy, but they also occur naturally as a
result of thermal vibrations.
An interstitial is an atom that occupies a place outside the normal lattice position. It may be the
same type of atom as the others (self interstitial) or an impurity atom.
Impurities are often added to materials to improve the properties. For instance, carbon added in
small amounts to iron makes steel, which is stronger than iron. Boron impurities added to silicon
drastically change its electrical properties.
Dislocations—Linear Defects:
Dislocations are abrupt changes in the regular ordering of atoms, along a line (dislocation line) in
the solid. They occur in high density and are very important in mechanical properties of material.
They are characterized by the Burgers vector, found by doing a loop around the dislocation line
and noticing the extra interatomic spacing needed to close the loop. The Burgers vector in metals
points in a close packed direction.
Edge dislocations occur when an extra plane is inserted. The dislocation line is at the end of the
plane. In an edge dislocation, the Burgers vector is perpendicular to the dislocation line.
2D :
Screw dislocations resul.
Keplers First Law was proposed in about 1605 on the basis of celest.pdf
Kepler\'s First Law was proposed in about 1605 on the basis of celestial observations; it was
later confirmed using Newton\'s Laws of Motion. According to Kepler\'s First Law, the orbits of
planets (and other bodies such as asteroids) revolving around the Sun are ellipses with the Sun at
one focus. Polar coordinates are ideally suited for describing planetary orbits, because the
description of an ellipse in polar coordinates assumes that one focus of the ellipse is at the origin.
Recall a few facts about ellipses in polar coordinates. One equation of a conic section in polar
coordinates is where 0 lessthanorequalto theta lessthanorequalto pi. When the eccentricity
satisfies 0

Journalism question
I need to write a news story in pyramid style. The story should have opinions of 10 strangers.
The question for those stranges and the topic of the story is - What do you think about the
refugee situation in Europe, and what should be the United States\' involvement?
Solution
refugees are the people who enters into the other country whithout their acceptance. here these
people came here to fulfill their basic needs of food and shelter. they are the people other than
the home country and came like a migrants or pirates. majoirty of the people who belongs to
syria and its neighbour nations are entering into majority of the european nations. and these
nations are going to be serve the people in different aspects.
and all those countries have a special regulaiton about it, which country has to provide support to
higest number of refugees and which is the next one.
here the role of US is indirectly US is leading the majority of the UK countries like Briton. and
they are supporting the nations who are providing facilities to the refugees..

You are responsible for convening a major event in which senior offi.pdf
You are responsible for convening a major event in which senior officials from several state
governments will try to come to an agreement on environmental issues. It is well known that
some officials posture so that they appear superior, whereas others are highly motivated to solve
the environmental problems that cross adjacent states. What team decision-making problems are
likely to be apparent in this government forum and what actions can you take to minimize these
problems?
Solution
I would consider the following team decision -making problems in this example:
1. Not fully aware about the current situation : State the current situtation and enlist the gravity
of the current issues being faced by several state governments: This is important to then arive at
a common goal or analyze the impact of various issues on the individual state governements and
the center, This should be the starting point for all state Governements considering that all of
them will be acing several environmental issues with difference and variability in severeity. For
eg: Noise Pollution, Ozone depletion, impact of radiation, Air and Sea Pollution, Diesease due to
environmental issues. Actions that I would take to minimize this problem: Ensure that the state
governments have complete facts and data and inputs of environmentalists, citizen groups on the
current situation and have it documented.
2. Goals are unclear : Each State must agree on the actions items to be achieved by setting
CLEAR goals. If the group begins to work on a solution before fully comprehending their goals,
the final result may not be the best fit for them. Actions that I would take to minimize this
problem: Each State can have a sub-goal with one common goal for the center. This will ensure
that there is enough motivation for each state to implement the agreed action items.
3: Absence of Complete and correct information: Another important aspect of team decision
making is having correct information about the given situation. Not only should all of the
information presented to the group be factually correct, but it should also be time relevant. If the
team attempts to arrive at a decision with too little or incorrect information, the final result will
likely result in an error and cost the governments time and money.Actions that I would take to
minimize this problem: Validate the information presented by the states and ensure that it is pre-
validated by neutral organisations.
4. Incorrect information about Data Available: The State Governments needs to involve
environmentalists and statisticians to interpret the data that is available to complete the study of
the current situation. As mentioned previously, it is essential that a team have all of the correct
information before attempting to come to a decision. However, even if the group has all of the
correct information the end result can still have flaws. Group members need to carefully interpret
and understand all of the data that they have to .

What happens to a B-mode image without post processing filtersWha.pdf
What happens to a B-mode image without post processing filters?
What happens to a B-mode image without envelope detection?
Solution
1) It is often necessary to do a wide variety of post processing to form the best quality ultrasound
images before displaying the information for human observation. This post processing might
include various techniques and the order depend on the system configuration. The key task
involved in post processing is conversion of raw data into displayed data.
>> For speckle reduction, various methods such as wavelet decomposition, anisotropic fitering
and bilateral filtering can be applied. These techniques follow spatial compounding which is a
multi imaging method where, by combining views of the same object from different angles, each
having an uncorrelated speckle realization, the resulting image will have significantly reduced
speckle.
>> Lowpass and Highpass fitering techniques are apllied for obtaining smoothening and for
higlighting the edges respectively.
>> Histogram eualization is typically used to improve image contrast and quality, and involves
doing a gray level transformation to obtain a uniform histogram from images with un-balanced
histograms.
To conclude, the B-mode imaging without these post processing techniques makes impossible
human intrepretation and observation.
2) The amplitude of the reflected sound waves forms the basis for the ultrasound image at its
focal point location. Envelope detection along with log compression is used to detect the peaks in
the received signal and to reduce the dynamic range of the received signals for efficient display.
Once all of the amplitudes for all of the focal points have been detected, they can be displayed
for analysis by the doctor or technician.
The B-mode imaging without envelope detection allows all reflected ultrasound waves for post
procesing that leads to a reconstruction a noisy image which is useless for diagnosis..

1.Which of the following would BEST explain why a preoperational chi.pdf
1.Which of the following would BEST explain why a preoperational child would have difficulty
understanding that cats can be both pets and wild animals?
A. object permanence
B. centration
C. the imaginary audience
D. animism
2. 4 year old kanaan\'s mother make\'s him a ham and cheese sandwhich for lunch. Kanan refuses
to eat the sandwhich, stating that he does not like cheese. When Kanaan\'s mother removes the
cheese from the sanwhich, he still refuses to eat and again states he does not like cheese. This is
an example of:
A.overimitation
B. overregulation
C. fast-mapping
D. underrutilization
Solution
1. B centration
This is a condition usually occurs in children at preoperational stage wherein they can focus on
any one salient feature and ignore rest all others.
Such as this child, who cannot focus on cat being both pet and wild, he can focus on either of
them.

1. How does the temperature influence the plasticity and elasticity .pdf
1. How does the temperature influence the plasticity and elasticity of materials?
2. What does it mean by ideal materials? And which real material is close to the definition of
ideal materials?
3. What are the imperfections found I solid materials? Describe them.
Please answer.
Solution
1)
The effect of temperature on elasticity is difficult to isolate, because there are numerous factors
affecting it. For instance, the bulk modulus of a material is dependent on the form of its lattice,
its behavior under expansion, as well as the vibrations of the molecules, all of which are
dependent on temperature.
Inelastic deformations of rocks and concrete are primarily caused by the formation of
microcracks and sliding motions relative to these cracks. At high temperatures and pressures,
plastic behavior can also be affected by the motion of dislocations in individual grains in the
microstructure
2)
Endless supply and close available source
Cheap to produce
Energy efficient
Appropriately strong, stiff, and temperature stable
Lightweight
Corrosion resistant
Produces no harmful effects (for environment or people)
Biodegradable or completely recyclable
It can be a difficult and complex process to find the ideal material for a specific product or
application. This process is called the material selection.
3) Imperfections in Solids:
Materials are often stronger when they have defects. The study of defects is divided according to
their dimension:
0D (zero dimension) – point defects: vacancies and interstitials. Impurities.
1D – linear defects: dislocations (edge, screw, mixed)
2D – grain boundaries, surfaces.
3D – extended defects: pores, cracks.
0D (Zero dimension):
A vacancy is a lattice position that is vacant because the atom is missing. It is created when the
solid is formed. There are other ways of making a vacancy, but they also occur naturally as a
result of thermal vibrations.
An interstitial is an atom that occupies a place outside the normal lattice position. It may be the
same type of atom as the others (self interstitial) or an impurity atom.
Impurities are often added to materials to improve the properties. For instance, carbon added in
small amounts to iron makes steel, which is stronger than iron. Boron impurities added to silicon
drastically change its electrical properties.
Dislocations—Linear Defects:
Dislocations are abrupt changes in the regular ordering of atoms, along a line (dislocation line) in
the solid. They occur in high density and are very important in mechanical properties of material.
They are characterized by the Burgers vector, found by doing a loop around the dislocation line
and noticing the extra interatomic spacing needed to close the loop. The Burgers vector in metals
points in a close packed direction.
Edge dislocations occur when an extra plane is inserted. The dislocation line is at the end of the
plane. In an edge dislocation, the Burgers vector is perpendicular to the dislocation line.
2D :
Screw dislocations resul.
Keplers First Law was proposed in about 1605 on the basis of celest.pdf
Kepler\'s First Law was proposed in about 1605 on the basis of celestial observations; it was
later confirmed using Newton\'s Laws of Motion. According to Kepler\'s First Law, the orbits of
planets (and other bodies such as asteroids) revolving around the Sun are ellipses with the Sun at
one focus. Polar coordinates are ideally suited for describing planetary orbits, because the
description of an ellipse in polar coordinates assumes that one focus of the ellipse is at the origin.
Recall a few facts about ellipses in polar coordinates. One equation of a conic section in polar
coordinates is where 0 lessthanorequalto theta lessthanorequalto pi. When the eccentricity
satisfies 0
Solution
planet earth has the most nearly circular orbit.
Journalism questionI need to write a news story in pyramid style. .pdf
Journalism question
I need to write a news story in pyramid style. The story should have opinions of 10 strangers.
The question for those stranges and the topic of the story is - What do you think about the
refugee situation in Europe, and what should be the United States\' involvement?
Solution
refugees are the people who enters into the other country whithout their acceptance. here these
people came here to fulfill their basic needs of food and shelter. they are the people other than
the home country and came like a migrants or pirates. majoirty of the people who belongs to
syria and its neighbour nations are entering into majority of the european nations. and these
nations are going to be serve the people in different aspects.
and all those countries have a special regulaiton about it, which country has to provide support to
higest number of refugees and which is the next one.
here the role of US is indirectly US is leading the majority of the UK countries like Briton. and
they are supporting the nations who are providing facilities to the refugees..

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.
