Compare and contrast protein import into the ER and into the nucleus.pdf
Compare and contrast protein import into the ER and into the nucleus. List at least two major
differences in the mechanisms and speculate on why the nuclear mechanism might not work for
ER import.
Solution
The Proteins are imported into the nucleus from the cytoplasm only after thay have been
synthesized,folded and properly assembled into complexes. They carry a sequence of amino
acids that acts as a tag called as Nuclear localization signals (NLS) ,bound by importins. In
contrast, all the unfolded polypeptide chains will be imported or translocated into ER as they are
been made by the ribosomes. Though ribosomes function in the cytosol they are assembled in the
nucleus where as the enzyme complexes function in the nucleus and assembles in the cytosol.
But, both these ribosomes and enzyme complexes are transported through a nuclear pore intact.
These Nuclear pores are gates, always opened for small molecules; in contrast, translocation
channels in the ER membrane will be normally closed and open only after the ribosome has
attached to the membrane. The ER membrane remains impermeable to small molecules during
the translocation process, as the ER is a major store for Ca2+ ions in the cell, and Ca2+ ions
released into the cytosol must be tightly controlled.
Nuclear localization signals (NLS) are not cleaved off after the protein is imported into the
nucleus; in contrast, ER signal peptides are usually cleaved off.
Nuclear localization signals (NLS) are needed inorder to reimport nuclear proteins repeatedly
after they have been released into the cytosol i.e during mitosis, when the nuclear envelop breaks
down..

Dimitri and Rita eat some donuts for breakfast and then spend the mo.pdf
Dimitri and Rita eat some donuts for breakfast and then spend the morning at an amusement
park. After a few hours of riding the Super Looper Double Twist Dimitri feels nauseous and
regurgitates the donuts. Rita is fine, but Dimitri has developed a ________, and the next time
they stop for donuts, Dimitri immediately feels ill.
a. taste aversion
b. taste response
c. unconditioned aversion
d. unconditioned response
Solution
Taste aversion is a condition which is generally developed after ingestion of food that causes
nausea, vomiting, and sickness.
This condition serves as a mechanism to avoid poisonous substances before they can cause harm
to our body.
This condition is most commonly seen in human beings.
When a person eats bad food, he develops nausea and becomes aversive to that food.
The same thing happened in the above case. Dimitri has developed a food aversion for donuts.
The next time they stop for donuts, Dimitri immediately feels ill.
Therefore, option A is correct..

behavioral and physiological characteristics in response to environmental condition. Inducible
defenses are a ubiquitous form of plasticity that involve the production of chemicals,
morphologies, or behaviors by prey species in response to predator cues. These changes reduce
prey vulnerability to inducing predators or herbivores..
Will th ebelow code work andif not please help me fix it. Basically .pdf
Will th ebelow code work andif not please help me fix it. Basically I am taking in a line of code
and we are supposed to use fail state to figure out which kind of format the line will follow. It
will either follow one of two formats. So I am trying to say if while reading in it hits something
that doesn\'t work it must be the OTHER kind of line. Am I using clear and fail functions
correctly? It is important that when it fails the next value being read in goes into the place where
it failed reading in.
So if it tries to read something in and it fails the next value read in should go into THAT value
and not the next one.

Which of the following is NOT a benefit of breathing through the nose? extraction of heat and
moisture from the air leaving the nasal cavity destruction of pathogens entering the nasopharynx
filtration of the air entering the nasal cavity heating and moistening the air entering the nasal
cavity
Solution

what is the transport process for a methane gas leakSolutionS.pdf
what is the transport process for a methane gas leak?
Solution
Scientists have developed a material made out of a mixture of silica and water which can soak up
large quantities of methane molecules. The material looks and acts like a fine white powder
which, if developed for industrial use, might be easily transported or used as a vehicle fuel.
Methane is the principal component of natural gas and can be burnt in oxygen to produce carbon
dioxide and water. The abundance of the gas and its relatively clean burning process makes it a
good source of fuel, but due to its gaseous state at room temperature, methane is difficult to
transport from its source.
Many natural gas reserves are geographically remote and can only be extracted via pipelines, so
there is a need to look for other ways to transport the gas. It has been suggested that methane gas
hydrate could be used as a way of containing methane gas for transportation. The disadvantage
of methane gas hydrate for industry use is that it is formed at a very slow rate when methane
reacts with water under pressure.
To counteract these difficulties, a method to break water up into tiny droplets to increase the
surface area in contact with the gas can be used. Mixing water with a special form of silica – a
similar material to sand – which stops the water droplets from coalescing. This ‘dry water’
powder soaks up large quantities of methane quite rapidly at around water’s normal freezing
point.
‘Dry water’ could be more economical than other potential products because it is made from
cheap raw materials. The material may also have industrial applications if methane could be
stored more conveniently and used to power clean vehicles..
Summarize the article Trading liberty for illusions by Wendy Kam.pdf
Summarize the article \"Trading liberty for illusions\" by Wendy Kaminer in 300 words by
following these steps: - the central idea of the passage - what, who, why, where, when and how -
the author\'s conclusion - the subject of the description and it\'s key feature(s)
Solution
The central idea of the article is about how the September 11 attacks have affected the civilian
population. In such circumstances, people are really scary and it is the responsibility of the
government to take all necessary precautions to secure its citizens. But the actions adhered to go
beyond the logical approach to safety by using several surveillance devices to track criminals or
abnormal behavior.
Kaminer accuses government of ignoring the civil liberties and the processes followed were
pointless and demonstrated its failures. She further adds that Americans have had to trade their
privacy with security, which means there is no privacy. The ways facial recognition was used
and abused, she says it constitutes a threat to security and liberty, not a promise of security.
The hard-core trained criminals fooled the intelligence surveillance system by suppressing their
emotions, behaviors, and facial expressions which proved the systems to be highly inefficient.
This leaves technology surveillance system a very controversial topic in the United States. She
goes on to say that the government is divided between using law as it was intended or breaking
law to meet special interest breaching security of the people it is supposed to protect. The
government should not exploit the gullibility of the citizens, for dissenters will start questioning
the credibility of the American philosophy.
What she concludes is that though technological advancement is geared up at improving security,
it should be relied upon as the most accurate measure against threat. The government need a
sober approach to security and privacy and should not rely upon the existing systems, laws, and
technology.

what is a shared derived charterer and how is it useful for construc.pdf
what is a shared derived charterer and how is it useful for constructing a phylogeny ?
Solution
Phylogeny can be understood as the science of developmental history of an organism with
respect to other organisms. Since the origin of an individual remains unknwon and
developmental characters can be measures only relative to other known organisms, the science of
phylogeny is based upon relavance of the features of a developing organism with respect to other
organisms whose features have been already well studied. For this purpose, the extent of
relatedness and differences between two or more organisms are generally studied. There are
some features which remain exclusive for a species whereas some features are common in
different species. These common features are termed as \'shared derived characters\' because it is
supposed that owing to their presence, anatomical relavance and similarities in physiological
function in different species, these features must have been orginated from a common ancestor
and gradually shared by different species for development. Thus, the more is the number of
shared derived characters between two or more species, the more likely is their evolutionary
relatedness.
For example, while constructing a phylogeny tree, the index of these shared derived characters
remains highly useful. It helps in grouping and clssifying organisms based upon their
evolutionary history and evident relatedness based upon number of shared characters. For
example, all organisms with jointed feet are placed under phylum arthropoda. After that,
organisms with paired feet and un-paired feet are differentiated either as millipeds or centipeds.
After that, organisms are differentiated based upon their mouth structures and so on. Thus, the
occurence of jointed feet, nature of feet and distribution of body plates on mouth cavity represent
shared derived characters. These characters can be further elaborated at anatomical and
molecular levels.
Thus, this clearly explains the role of shared derived charterer and its usefullness for
constructing a phylogeny tree..

Solution
2) Thermodynamics:
Thermodynamics is the branch of physics that deals with the relationships between heat and
other forms of energy. In particular, it describes how thermal energy is converted to and from
other forms of energy and how it affects matter.
3) Energy :
Measure of the ability of a body or system to do work or produce a change, expressed usually in
joules or kilowatt hours (kWh). No activity is possible without energy and its total amount in the
universe is fixed. In other words, it cannot be created or destroyed but can only be changed from

4) First law of thermodynamics:
The First Law of Thermodynamics states that heat is a form of energy, and thermodynamic
processes are therefore subject to the principle of conservation of energy. This means that heat
energy cannot be created or destroyed. It can, however, be transferred from one location to
another and converted to and from other forms of energy.
5) Second law of Thermodynamics :
The second law of thermodynamics states that the total entropy of an isolated system always
increases over time, or remains constant in ideal cases where the system is in a steady state or
undergoing a reversible process. The increase in entropy accounts for the irreversibility of
natural processes, and the asymmetry between future and past.
6) System :
A thermodynamic system is a quantity of matter of fixed identity, around which we can draw a
boundary.
7)Closed system :
Closed systems exchange energy but not matter with an outside system.
8) Yes, In closed system energy may cross the boundary.

Patient was diagnosed with x-linked agammaglobulinemia leading to re.pdf
Patient was diagnosed with x-linked agammaglobulinemia leading to recurrent bacterial
infections. Patient was determined by DNA sequencing to have a nonsense mutation in the btk
gene on his X chromosome resulting in premature truncation of the Bruton’s tyrosine kinase
(BTK) protein. This mutation has been previously reported in patients with susceptibility to
bacterial infections resulting in recurrent infection. Mother is heterozygous for the mutation and
received genetic counseling in case they decide to have additional offspring as ~50% of male
children will have similar disease, and 50% of daughters will be asymptomatic carriers. How
would you treat this patient? What are some possible side effects associated with this treatment?
Do the pros outweigh the cons? Please be specific.
Solution
There is 30-50% chance of XLA patients having a positive family history of genetic inheritance.
The rest of the cases occur as random mutations. XLA diagnosis usually begins due to a history
of recurrent infections, mostly in the respiratory tract, through childhood. This is due to humoral
immunodeficiency. The most common treatment for XLA is an intravenous infusion of
immunoglobulin (IVIg, human IgG antibodies) every 3–4 weeks, for life. IVIg is a human
product extracted and pooled from thousands of blood donations. IVIg does not cure XLA but
increases the patient\'s lifespan and quality of life, by generating passive immunity, and boosting
the immune system. With treatment, the number and severity of infections is reduced. With IVIg,
XLA patients may live a relatively healthy life. A patient should attempt reaching a state where
his IgG blood count exceeds 800 mg/kg. The dose is based on the patient\'s weight and IgG
blood-count. Antibiotics are another common supplementary treatment. Local antibiotic
treatment are preferred over systemic treatment (pills) for long-term treatment, if possible.One of
the future prospects of XLA treatment is gene therapy, which could potentially cure XLA. Gene
therapy technology is still in its infancy and may cause severe complications such as cancer and
even death. XLA patients are specifically susceptible to viruses of the Enterovirus family, and
mostly to: polio virus, coxsackie virus and Echoviruses. These may cause severe central nervous
system conditions as chronic encephalitis, meningitis and death. An experimental anti-viral
agent, pleconaril, is active against picornaviruses. XLA patients, however, are apparently
immune to the Epstein-Barr virus (EBV), as they lack mature B cells needed for the viral
infection. Patients with XLA are also more likely to have a history of septic arthritis.
Agammaglobulinemia (XLA) is similar to the primary immunodeficiency and their clinical
conditions and treatment are almost identical..

Olfactory Nerve Solutionolfactory nerve is a type of a cranial .pdf
Olfactory Nerve
Solution
olfactory nerve is a type of a cranial nerve. It is first of the twelve cranial nerves and is shortest
of all. It\'s sensory data is responsible for smell and partially responsible for taste. It\'s olfactory
receptors are located in the mucosal membrane of the nasal cavity. It bypass the brain stem and
connects directly to the brain.
Mechanism of smell:
chemicals enters nose -----> enters into a nasal cavity ---->region of olfactry epthelium covered
with cilia on side and axon of the olfactory nerve on the other ----> these axons enter into skul
through cribriform plate-----> then they get together at olfactory bulb------> passes signal to
olfactory tract -----> brain-----> brain interpretate specific pattern of impulses as specific smell..
Let R be a ring such that 0 is both the additive identity and the mu.pdf
Let R be a ring such that 0 is both the additive identity and the multiplicative identity. Show that
there is only one element in R.
Solution
Let a be an arbitrary element of the ring R. Since 0 is the multiplicative identity, we have 0 *a =
a *0 = a. However, 0 * a = a *0 = 0 for all a in R. Therefore a = 0. Thus, there is only one
element in R i.e. 0..

2. The Lorenz curve measures inequality in person income distribution. What is the difference
between personal income distribution and functional income distribution?
Solution
Personal income distribution shows differences in income of citizens among a nation. On the
otherhand, functional income distribution may occur due to difference in factor rewards to
production, viz. wages, rent, interest and profits. The former one belongs to the discussion of
labour market and the later one is determined in input/factor market that ultimately show factor
rewards..

Phenotypic plasticity refers to the ability of a genotype to exhibit alternative morphological,
behavioral and physiological characteristics in response to environmental condition. Inducible
defenses are a ubiquitous form of plasticity that involve the production of chemicals,
morphologies, or behaviors by prey species in response to predator cues. These changes reduce
prey vulnerability to inducing predators or herbivores..

Will th ebelow code work andif not please help me fix it. Basically I am taking in a line of code
and we are supposed to use fail state to figure out which kind of format the line will follow. It
will either follow one of two formats. So I am trying to say if while reading in it hits something
that doesn\'t work it must be the OTHER kind of line. Am I using clear and fail functions
correctly? It is important that when it fails the next value being read in goes into the place where
it failed reading in.
So if it tries to read something in and it fails the next value read in should go into THAT value
and not the next one.

what is the transport process for a methane gas leakSolutionS.pdf
what is the transport process for a methane gas leak?
Solution
Scientists have developed a material made out of a mixture of silica and water which can soak up
large quantities of methane molecules. The material looks and acts like a fine white powder
which, if developed for industrial use, might be easily transported or used as a vehicle fuel.
Methane is the principal component of natural gas and can be burnt in oxygen to produce carbon
dioxide and water. The abundance of the gas and its relatively clean burning process makes it a
good source of fuel, but due to its gaseous state at room temperature, methane is difficult to
transport from its source.
Many natural gas reserves are geographically remote and can only be extracted via pipelines, so
there is a need to look for other ways to transport the gas. It has been suggested that methane gas
hydrate could be used as a way of containing methane gas for transportation. The disadvantage
of methane gas hydrate for industry use is that it is formed at a very slow rate when methane
reacts with water under pressure.
To counteract these difficulties, a method to break water up into tiny droplets to increase the
surface area in contact with the gas can be used. Mixing water with a special form of silica – a
similar material to sand – which stops the water droplets from coalescing. This ‘dry water’
powder soaks up large quantities of methane quite rapidly at around water’s normal freezing
point.
‘Dry water’ could be more economical than other potential products because it is made from
cheap raw materials. The material may also have industrial applications if methane could be
stored more conveniently and used to power clean vehicles..
Summarize the article Trading liberty for illusions by Wendy Kam.pdf
Summarize the article \"Trading liberty for illusions\" by Wendy Kaminer in 300 words by
following these steps: - the central idea of the passage - what, who, why, where, when and how -
the author\'s conclusion - the subject of the description and it\'s key feature(s)
Solution
The central idea of the article is about how the September 11 attacks have affected the civilian
population. In such circumstances, people are really scary and it is the responsibility of the
government to take all necessary precautions to secure its citizens. But the actions adhered to go
beyond the logical approach to safety by using several surveillance devices to track criminals or
abnormal behavior.
Kaminer accuses government of ignoring the civil liberties and the processes followed were
pointless and demonstrated its failures. She further adds that Americans have had to trade their
privacy with security, which means there is no privacy. The ways facial recognition was used
and abused, she says it constitutes a threat to security and liberty, not a promise of security.
The hard-core trained criminals fooled the intelligence surveillance system by suppressing their
emotions, behaviors, and facial expressions which proved the systems to be highly inefficient.
This leaves technology surveillance system a very controversial topic in the United States. She
goes on to say that the government is divided between using law as it was intended or breaking
law to meet special interest breaching security of the people it is supposed to protect. The
government should not exploit the gullibility of the citizens, for dissenters will start questioning
the credibility of the American philosophy.
What she concludes is that though technological advancement is geared up at improving security,
it should be relied upon as the most accurate measure against threat. The government need a
sober approach to security and privacy and should not rely upon the existing systems, laws, and
technology.

what is a shared derived charterer and how is it useful for construc.pdf
what is a shared derived charterer and how is it useful for constructing a phylogeny ?
Solution
Phylogeny can be understood as the science of developmental history of an organism with
respect to other organisms. Since the origin of an individual remains unknwon and
developmental characters can be measures only relative to other known organisms, the science of
phylogeny is based upon relavance of the features of a developing organism with respect to other
organisms whose features have been already well studied. For this purpose, the extent of
relatedness and differences between two or more organisms are generally studied. There are
some features which remain exclusive for a species whereas some features are common in
different species. These common features are termed as \'shared derived characters\' because it is
supposed that owing to their presence, anatomical relavance and similarities in physiological
function in different species, these features must have been orginated from a common ancestor
and gradually shared by different species for development. Thus, the more is the number of
shared derived characters between two or more species, the more likely is their evolutionary
relatedness.
For example, while constructing a phylogeny tree, the index of these shared derived characters
remains highly useful. It helps in grouping and clssifying organisms based upon their
evolutionary history and evident relatedness based upon number of shared characters. For
example, all organisms with jointed feet are placed under phylum arthropoda. After that,
organisms with paired feet and un-paired feet are differentiated either as millipeds or centipeds.
After that, organisms are differentiated based upon their mouth structures and so on. Thus, the
occurence of jointed feet, nature of feet and distribution of body plates on mouth cavity represent
shared derived characters. These characters can be further elaborated at anatomical and
molecular levels.
Thus, this clearly explains the role of shared derived charterer and its usefullness for
constructing a phylogeny tree..

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
