Solution
Kevin Mitnick:
-->The hacker who change his hat.He is the most famous hacker drones on about technoology.
-->The nebulous language of section 814 does not clearly differenciate between a computer
crime or an electronic
prank and an international act of terror.
--> Kevin Mitnick did anything all that illegal, but there\'s no denying that he was the world\'s
first high profile computer criminal.
-->hacker Kevin Mitnick is (although he is undeniably great), but how devastatingly effective he
is at tricking people into
revealing critical information in casual conversations
-->Under this legislation,Mafiaboy or kevin Mitnick would be considered a cyber-terrorist,even
though they were
not acting against critical national infrastructures.
-->This is like equating a water-balloon attack with a political assassination.
-->Mitnick became a legend in the nascent hacking community for some of his cunning stunts:
dumpster-diving
outside businesses to uncover discarded staff manuals and access codes, posing as an IT
department staff member
so that other workers would voluntarily cough up passwords over the phone.
-->He was proclaimed \"the world\'s most notorious cyber-thief\" in The New York Times, and
\"the poster boy for computer crime\"
on TV\'s 60 Minutes.
--> The FBI finally nailed him, living under a fake identity in North Carolina.
-->Mitnick was presented in court as extremely dangerous, \"the world\'s most wanted\"
computer criminal, and his trial
coincided with a time when American cyber paranoia was at an all-time high.
Stuxnet:
--> The FBI defines cyber terrorism as a “premeditated, politically motivated attack against
information,
computer systems, computer programs and data which results in violence against non-combatant
targets by
subnational groups or clandestine agents.
-->a terror group might launch a “digital Pearl Harbor” to Stuxnet-like sabotage (ahem,
committed by state forces)
to hacktivism, WikiLeaks and credit card fraud. As one congressional staffer put it, the way we
use a term like
cyber terrorism “has as much clarity as cybersecurity — that is, none at all.
--> “It is possible for a terrorist group to develop cyber-attack tools on their own .
In the computer security context, a hacker is someone who seeks and exploits weaknesses in a computer system or computer network. Hackers may be motivated by a multitude of reasons, such as profit, protest, challenge, enjoyment,[1] or to evaluate those weaknesses to assist in removing them. The subculture that has evolved around hackers is often referred to as the computer underground and is now a known community. While other uses of the word hacker exist that are related to computer security, such as referring to someone with an advanced understanding of computers and computer networks, they are rarely used in mainstream context. They are subject to the longstanding hacker definition controversy about the term's true meaning. In this controversy, the term hacker is reclaimed by computer programmers who argue that someone who breaks into computers, whether computer criminal (black hats) or computer security expert (white hats), is more appropriately called a cracker instead. Some white hat hackers, who claim that they also deserve the title hacker, and that only black hats should be called "crackers"

Many of the technical controls put into place can be circumvented with a simple phone call. Recently, famed hacker Kevin Mitnick demonstrated this, by breaking into Sprint's backbone network. Rather than mounting a buffer overrun or denial-of-service (DoS) attack, Mitnick simply placed a call posing as a Nortel service engineer and persuaded the staff at Sprint to provide log-in names and passwords to the company's switches, under the guise that he needed them to perform remote maintenance on the system. Once the password information had been obtained, Mitnick was able to dial in and manipulate Sprint's networks at will.
Many people believe this was an isolated incident, and they would not fall for a similar act of social engineering, but Mitnick gained notoriety during the 1980s and 1990s, by performing similar techniques on computer networks around the world. Mitnick's more notorious crimes included accessing computer systems at the Pentagon and the North American Defense Command (NORAD), and stealing software and source code from major computer manufacturers. Kevin Mitnick was arrested six times. He has been working as a consultant, specializing in social engineering techniques, having gone straight after serving a five-year sentence for his most recent crime. He has authored several books regarding social engineering, including

Solution
sin theta ( cosec theta - sin theta )
cosec theta = 1/ sin theta
so we can write
sin theta ( 1 / sin theta - sin theta )
= sin theta ( 1 - sin^2 theta / sin theta )
= ( 1- sin^2 theta )
1 - sin^2 theta = cos^2 theta ( by trigonometric identity )

mutations in the LDL receptor are linked to familial hypercholestero.pdfdeepakarora871
mutations in the LDL receptor are linked to familial hypercholesterolemia. there are 5 classes of
familial hypercholesterolemia that are characterized by a specific defect in LDL receptor
synthesis, trafficking or function. Hypothesize on the 5 different causes of this disease.
Solution
Familial hypercholesterolemia ( FH) is a Type II hyperlipoproteinemia caused by decreased
number of normal LDL (LOW DENSITY LIPOPROTEINS) receptors due to the mutation in
LDLR gene. The condition is marked by elevated LDL - a compound that regulates the synthesis
and transport of cholesterol in the body, causing high cholesterol levels in the blood. This may
put individuals at an increased risk of heart attacks.
Types of FH
Heterozygous FH is the most common type and affects 1 in 500 individuals where the
individuals have premature cardiovascular disease at the age of 30-40.
Homozygous FH occurs in 1 in a million births and is usually seen in children.
LDL receptor (LDLR):
Defects in LDLR are functionally divided into 5 classes depending on the impact of mutation:
Class 1
Class 1 mutations affect the synthesis of the receptor in the endoplasmic reticulum (ER). In other
words, receptor is not synthesized.
Class 2
Class 2 mutation in LDLR prevents it\'s transportation from endoplasmic reticulum to golgi
complex ( for modification of the receptor and it\'s expression on cell surface).
Class 3
In class 3 mutation the receptor has difficulty in binding to the LDL on cell surface.
Class 4
In this mutation LDLR binds to LDL, but does not cluster in clathrin coated vesicles for receptor
mediated endocytosis.
Class 5
The receptor donot circulate back to cell surface..

Match the following parts of an EKG with what part of the heartbeat t.pdfdeepakarora871
Match the following parts of an EKG with what part of the heartbeat they mark. Interval
between QRS & T waves QRS wave P Wave T Wave Interval between P & QRS waves Match
the following techniques with what they measure. Auscultation Electrocardiogram (EKG)
Sphygmomanometer Volume Pulse Recording
Solution
QRS WAVE - Ventricular depolarisation
P Wave - atrial depolarisation
T Wave - Ventricular repolarisation
The first deflection, the P wave, corresponds to current flows during atrial depolarisation. The
second deflection, the QRS complex, occurring approximately 0.15 s later, is the result of
ventricular depolarisation. It is a complex deflection because the paths taken by the wave of
depolarisation through the thick ventricular walls differ from instant to instant, and the currents
generated in the body fluids change direction accordingly. The final deflection, the T wave, is a
result of ventricular repolarisation.
Ausculation : Ausculation is the process of listening to sounds. Direct method uses only the ear
while the indirect method uses stethoscope to hear the sounds.
Electrocardiogram : Electrocardiogram is primarily a tool for evaluating the electrical events
within the heart. The action potentials of cardiac muscle cells can be viewed as batteries that
cause charge to move throughout the body fluids. These moving charges represent the sum of the
action potentials occurring simultaneously in many individual cells and can be detected by
recroording electrodes at the surface of the skin.
Sphygmomanometer : Sphygmomanometer is a device used to measure the blood pressure in the
arteries.
Volume pulse recording : Recording of the segmental flowing of blood in the limb as a result of
changes in the blood volume during cardiac cycle..

which is the known mean for an exponential function,
then In the context of the Poisson process, the parameter r is known as the rate of the process. On
average, there are 1 r time units between arrivals, so the arrivals come at an average rate of r per
unit time.
Now
Mx(t)= 1/r + rp/2

Lets try to summarize Darwins observations that drive changes in .pdfdeepakarora871
Let\'s try to summarize Darwin\'s observations that drive changes in species over time: From
these four observations, which two inferences did Darwin make?
Solution
Observation
Cite and Example
1. Variations in traits exist.
We can see variation in different skin colors of humans, Asian ladybird beetles show variation in
color and spot patterns, humans has variations in their eye color, and snail will have different
colored shell.
2.These variations (traits) are heritable
Parents will pass on their characteristics through heritability, like passing sex-linked traits which
are located on genes to their offspring.
For example, because of the passing of variation to offspring, the variation observed in offspring
will make them to look related to close relatives more when compared to other members of
population.
3. Species overproduce.
Some species will overproduce. thousands of seeds are produced by Dandelion, Fish will lay
millions of eggs and puffball fungus will overproduce the offspring
4. There is competition for resources; not all offspring survive.
Not all these offspring produced by the above organisms will survive. It might be due to
predation, lack of resources, and lack of favorable environment. So only those which can make
use of resources and escape from predation will survive.
. From these four observations, what two inferences did Darwin make?
1. Darwin was able to make an inference that offspring which has inherited better traits will have
better chance to survive and reproduce in the provided environment and only these will have
chance to produce more offspring than other individuals, and the offspring from these fit
organism will also thrive well.
2. Because of the tough competition, only individual equipped with better skills or ability will
have the chance to survive and reproduce, thus over the generation, only favorable traits will be
passing onto the future generation leading to their accumulation.

If the CFTR doesnt work correctly due to a mutation, Cl^- movement .pdfdeepakarora871
If the CFTR doesn\'t work correctly due to a mutation, Cl^- movement is blocked and an
abnormally thick sticky mucus is produced on the outside of the cell. This mucus clogs the
airways in the lungs, and increases the risk of infection by bacteria. Figure 2 illustrates a mutant
CFTR channel in the epithelial cells lining the lung. Suppose the Na^+ channel in the figure was
open. Why would more Na^+ enter a cell with mutant CFTR than a cell with normal CFTR?
How is solute composition of the mucus layer (outside of cell) affected by mutant CFTR? What
membrane protein not shown in this diagram would be important for maintaining ion
homeostasis, and why is it important?

How does the Drosophila embryo get its pair-rule stripes How is the .pdfdeepakarora871
How does the Drosophila embryo get its pair-rule stripes? How is the evenskipped enhancer
build to ensure transcription of even-skipped in stripes? Use the even-skipped stripe 2 enhancer
as an example. Describe in general terms the inputs of transcription factors, and how the
embryonic expression domains of these factors are generated in the Drosophila embryo.
Solution
Initially,12 nuclear divisions take place which result in a multinucleate syncitium which is an
early drosophilla embryo; formation of pole cells take place followed by cellularization and
gastrulation. During gastrulation, extension of germ band takes place driving the posterior trunk
regions around the posterior end and the dorsal side, here the first signs of segmentation are seen.
At the syncitial blastoderm stage anterior-posterior and dorso-ventral axes get fully established.
Maternal factors in the form of mRNAs and proteins specify the anterior-posterior axis of the
embryo and the dorso-ventral aspect is governed by the localization of maternal proteins within
the envelope of egg vitelline and the positional information.
Even skipped acts as a transcriptional repressor of numerous genes.There is a combination of
maternal factors, transcription activators, and repressors, which defines each stripe of eve already
patterned in the egg either prior to fertilization or prior to cellularization.There are regional
specific enhancers which governs the stripe pattern of eve transcription.A stripe-specific
enhancer regulate each stripe. As seen in the case of eve stripe 2,in the range of -1.5 and -1.0 kb
upstream from the eve start site a minimal stripe 2 enhancer has been identified which assures
eve transcription in the second pair rule stripe.

Each group should plot on graph paper the ½ life of the radioisotope.pdfdeepakarora871
Each group should plot on graph paper the ½ life of the radioisotopes using the special graph
paper supplied by the teacher. The y-axis has a log scale and begins at 100% of the parent
radioisotope present; the next point is 100/ 2, or 50% parent radioisotope present; the next point
is 50/2, or 25%; and so on.). For example, if the ratio of C-14 to C-13 is 1:3 than the fossil is
how old? 5600 +5600. Correct? For each of the radioisotopes listed above, make a radiometric
graph going to 3 half-lives. Be sure to make one graph using uranium-lead and potassium-argon
dating to one half life. This will become useful later. Why?
Uranium-Lead dating method
Very careful measurements in laboratories, made on VERY LARGE numbers of U-235 atoms,
have shown that each of the atoms has a 50:50 chance of decaying during about 704,000,000
years. In other words, during 704 million years, half the U-235 atoms that existed at the
beginning of that time will decay to Pb-207. This is known as the half life of U- 235. Many
elements have some isotopes that are unstable, essentially because they have too many neutrons
to be balanced by the number of protons in the nucleus. Each of these unstable isotopes has its
own characteristic half life. Some half lives are several billion years long, and others are as short
as a ten-thousandth of a second.
The uranium-lead radiometric dating scheme has been refined to the point that the error margin
in dates of rocks can be as low as less than two million years in two-and-a-half billion years. An
error margin of 2–5% has been achieved on younger Mesozoic rocks.
One of its great advantages is that any sample provides two clocks, one based on uranium-235\'s
decay to lead-207 with a half-life of about 700 million years, and one based on uranium-238\'s
decay to lead-206 with a half-life of about 4.5 billion years, providing a built-in crosscheck that
allows accurate determination of the age of the sample even if some of the lead has been lost.
Potassium-argon dating method
This involves electron capture or positron decay of potassium-40 to argon-40. Potassium-40 has
a half-life of 1.3 billion years, and so this method is applicable to the oldest rocks. Radioactive
potassium-40 is common in micas, feldspars, and hornblendes, though the closure temperature is
fairly low in these materials, about 125°C (mica) to 450°C (hornblende).

Dr. Liu did a genetic screen for yeast cells that fail to synthesize .pdfdeepakarora871
Dr. Liu did a genetic screen for yeast cells that fail to synthesize leucine (ie. leu^-). She first
exposed the yeast cells to X-ray and then she plated the cells on to a plate containing complete
medium. Then she replicated (using replicate plating technique) the colonies from the complete
medium onto two new plates (plate A and B). Indicate medium type in A and B plate and how
will she find the colony that is Leu- by comparing the colonies on A and B plates?
Solution
Replica plating technique identifies the nutritional auxotrophs by growing the microbes on
complete and minimal media. The complete media contain all the nutrients required for growth
and development of microbe uder study. The minimal media contain all but one nutrient for
which the microbe is supposed to be auxotroph. In the given question, Dr grows the colonies on
plate A (containing complete media) and plate B (containing media that lack leucine). The
auxotrophs which fail to synthesize leucine can grow on the plate A having complete media only.
The colonies of these auxotrophs are absent on the plate B with minimal media which does not
supplement the requirement of leucine by the auxotrophs. This is how, she can find out the Leu-
colonies on the plate A..
Children with Down Syndrome generally show a pattern of retarded men.pdfdeepakarora871
Children with Down Syndrome generally show a pattern of retarded mental development,
although some achieve higher intellectual levels than others. The intellectual achievements of
Down Syndrome children have been studied by numerous investigations, and several different
types of chromosomal abnormalities associated with the syndrome have been identified. Two
such abnormalities are called trisomy 21 and mosaicism. The levels of intellectual functioning of
trisomy 21 and Mosaic Down Syndrome were compared in the paper

Choose the statement that describes the first stage of phagocytosis .pdfdeepakarora871
Choose the statement that describes the first stage of phagocytosis Phagocytes form
pseudopodia at the site of inflammation in order to grab the invading microbe Phagocytes move
with deliberation along a gradient of stimulatory products at the site of injury Phagocytes make
their way to an inflammatory site by random chance Phagocytes release substances to attack the
extracellular microbe
Solution
Answer b: Phagocytes move with delibration along a gradient of stimulatory products at the site
of injury
Reason: Chemotaxis is the movement of phagocytes toward an increasing concentration of some
attractant such as bacterial factors (bacterial proteins, capsules, LPS, peptidoglycan, teichoic
acids, etc.), complement proteins (C5a), chemokines (chemotactic cytokines such as interleukin-
8 secreted by various cells), fibrin split products, kinins, and phospholipids released by injured
host cells..
Are logarithms prolems used for career jobsSolutionLogarithmi.pdfdeepakarora871
Are logarithms prolems used for career jobs?
Solution
Logarithmic (and exponential) functions are widely used in describing economic and physical
phenomenon such as compound interest, population growth, memory retention, decay of
radioactive materials. Instances are: a logarithmic function can be sued to relate the weight of an
animal and its lowest galloping speed. Sensation of sound in human ear is logarithmic to its
loudness. Scales to measure sound (decibel) is therefore, logarithmic. So is the scale used to
measure the magnitude of earthquakes, i.e. the Richter scale.
There are many careers that use exponential and logarithmic functions. Examples of such careers
include: astronomer, psychologist , archaeologist, forensic scientist, seismologist etc..

Is this correct? Demonstrate how you determined this.
Solution
Yeh this is correct
Star-forming clouds like this one are dynamic and evolving structures. Since the stars trace the
straight line pattern of spokes of a wheel, scientists believe that these are newborn stars, or
\"protostars.\" At a mere 100,000 years old, these infant structures have yet to \"crawl\" away
from their location of birth. Over time, the natural drifting motions of each star will break this
order, and the snowflake design will be no more..
June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
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

1. This is a 1 -2 page essay on an issue you found interesting while reading Cuckoos Egg.
Examples include the continuing conflict between the FBI and Apple or Kevin Mitnick or
Stuxnet or how terrorists use the Internet or how the US government decision to attack ISIS
digitally. These are master’s level essays not college descriptive essays. You must find and
analyze interesting and challenging issue. Prior to submitting the paper, you must submit a five
source annotated bibliography with two paragraphs about each source. The first is a summary of
the article. The second is your reflection on the article – what it makes you think about. Each
paragraph contains a minimum of five sentences. Submit to me on blackboard. The document
should include the paper and the annotated bibliography
Solution
Kevin Mitnick:
-->The hacker who change his hat.He is the most famous hacker drones on about technoology.
-->The nebulous language of section 814 does not clearly differenciate between a computer
crime or an electronic
prank and an international act of terror.
--> Kevin Mitnick did anything all that illegal, but there's no denying that he was the world's
first high profile computer criminal.
-->hacker Kevin Mitnick is (although he is undeniably great), but how devastatingly effective he
is at tricking people into
revealing critical information in casual conversations
-->Under this legislation,Mafiaboy or kevin Mitnick would be considered a cyber-terrorist,even
though they were
not acting against critical national infrastructures.
-->This is like equating a water-balloon attack with a political assassination.
-->Mitnick became a legend in the nascent hacking community for some of his cunning stunts:
dumpster-diving
outside businesses to uncover discarded staff manuals and access codes, posing as an IT
department staff member
so that other workers would voluntarily cough up passwords over the phone.
-->He was proclaimed "the world's most notorious cyber-thief" in The New York Times, and
"the poster boy for computer crime"
on TV's 60 Minutes.
--> The FBI finally nailed him, living under a fake identity in North Carolina.
2. -->Mitnick was presented in court as extremely dangerous, "the world's most wanted"
computer criminal, and his trial
coincided with a time when American cyber paranoia was at an all-time high.
Stuxnet:
--> The FBI defines cyber terrorism as a “premeditated, politically motivated attack against
information,
computer systems, computer programs and data which results in violence against non-combatant
targets by
subnational groups or clandestine agents.
-->a terror group might launch a “digital Pearl Harbor” to Stuxnet-like sabotage (ahem,
committed by state forces)
to hacktivism, WikiLeaks and credit card fraud. As one congressional staffer put it, the way we
use a term like
cyber terrorism “has as much clarity as cybersecurity — that is, none at all.
--> “It is possible for a terrorist group to develop cyber-attack tools on their own or to buy them
on the black market,” Lynn warned.
“A couple dozen talented programmers wearing flip-flops and drinking Red Bull can do a lot of
damage.”
-->Taking down hydroelectric generators, or designing malware like Stuxnet that causes nuclear
centrifuges to spin out of
sequence doesn’t just require the skills and means to get into a computer system. It’s also
knowing what to do once you are in.
To cause true damage requires an understanding of the devices themselves and how they run,
the engineering and physics behind the target.
-->The Stuxnet case, for example, involved not just cyber experts well beyond a few wearing
flip-flops, but also experts in areas that ranged
from intelligence and surveillance to nuclear physics to the engineering of a specific kind of
Siemens-brand industrial equipment.
-->It also required expensive tests, not only of the software, but on working versions of the
target hardware as well.
