Imagine a spherical balloon filled wild helium- the balloon itself is.pdf
Imagine a spherical balloon filled wild helium- the balloon itself is magically crafted to expand
and contract freely without exerting any restorative force Some weights (with negligible volume)
are hung from the balloon such that the total mass of helium + balloon + weights is m Assume
the balloon is surrounded by with constant density p_0 and constant pressure P_0, independent
of altitude.
Solution
Gas equation PV = nRT
As the pressure P is constant
P dV/dt = nR dT/dt
dV/dt =nR/P dT/dt
initial condition P0V0 = nRT0
dV/dt = (V0/T0) dT/dt
upward thrust on the ballon
F = Vg – mg
Differentiate with t , we have
dF/dt = gdV/dt
initial the balloon is at rest hence
V0 g – mg = 0 hence m = V0
mda/dt = gdV/dt
= g*(V0/T0)* dT/dt
da/dt = g/T0 * dT/dt
we can express rate of change of acceleration in terms of g, which has units of acceleration
da/dt = (1/T0)dT/dt
integrating it
a(t) = T(t)/T0
given T(t) = T0(2 - 1/t+1)
a(t) = 2 – 1/t+1
dv(t)/dt = 2 – 1/t+1
v(t) = 2t – ln(t+1).
If a substance has a pH of 4, is it acidic or basic. What type of io.pdf
If a substance has a pH of 4, is it acidic or basic. What type of ion is it going to give off when
dissolved in water?
Solution
If a substance has a pH of 4, it is acidic in nature.
An acid donates hydrogen ions. So,when this acid is dissolved in water (H2O), the balance
between hydrogen ions and hydroxide ions is shifted. There will be more hydrogen ions rather
than hydroxide ions in the solution. This kind of solution is called acidic solution.
H2O -----------------> H+ + OH-
Note:
If,
pH < 7 = Acidic in nature
pH = 7 = Neutral solutions
pH > 7 = Basic / Alkaline in nature.

Emperor penguins live on a diet of fish and crustaceans obtained fro.pdf
Emperor penguins live on a diet of fish and crustaceans obtained from cold Antarctic seawaters.
However, during their breeding cycle, they migrate to inland breeding grounds nearly 100 km
away from their source of food. As a result, male emperor penguins do not eat for the two
months that they protect and incubate the single egg laid by their mate. During this time, each of
the tens of thousands of male penguins can lose up to 50% of its body mass (by dry weight).
Where does the majority of this penguin mass go?A. The mass is converted to energy and used

why is there an uneven distribution of photosystem 1 and 2 on the th.pdf
why is there an uneven distribution of photosystem 1 and 2 on the thylakoid membrane?
Solution
Photosynthesis is carried out by the cyanobacteria, plants involved the absorption of light and the
conversion of its energy into chemical energy. The photosynthetic apparatus is made up of 4
multiprotein complexes, which are asymmetrically embedded in the thyalkoid memberane. It is
the high structural and functional coordination between these 4 complexes, which enables the
efficient coupling of photosynthetic electron transfer and photophosphorylation.
The 4 complexes - Photosystem II (PSII), cytochrome b6f complex, PS I and the proton-ATP
synthase, are unevenly distributed between the 2 regions of the thylakoids. The PS II complex is
situated in the appressed grana-lamella region, the PS I and the ATP synthase complex are
located in the non-appressed stroma-lamella region.
Light driven electron transfer is intiated with the oxidation of water mole. by the PS II complex
and the reduction of quinones associated with the PS II complex. The electrons are then
transferred across the memberane to plastocyanin via the Cyt b6f complex. Plastocyanin is a
copper protein facing the lumen of the thylakoids, is the secondary electron donor of the PS I
complex. In the PS I the electron are translocated across the memberane to ferredoxin which
further transfers them to NADP+. The membrane potental and proton gradient resulting from this
photochemical electron transport provide the motive force required for the formation of ATP by
the ATP synthase.
The transport of electron against the electrical potential and the formation of ATP and NADPH
are made possible due to the unique ability of the thylakoids to absorb light energy. The 2
pigment complexes (PS II and PS I) are responsible for harvesting the light and performing the
charge separation across the thylakoid memberanes.
Photosytem II (PS II):
1. PS II is located at the inner surface the grana thyalkoid memberane
2. The photocentre is P680
3. Pigments absorb shorter wavelengths of light (<680nm)
4. Participates only in non cyclic photophosphorylation
5. It is associated with photolysis of water
6. Main functions are ATP synthesis and hydrolysis of water
Photosystem I (PS I)
1. PS I is located at the outer surface the grana thylakoid memberane
2. The photocentre is P700

What is the purpose of testing a program with different dataSol.pdf
What is the purpose of testing a program with different data?
Solution
The purpose of testing a program functions according to the expectation. The overall goal of
testing is to find a bug that might effect the functioning of the program. There are various types
of testing and each serve their own purpose. Different data is used for each type of testing. We
have to check the whether internal module is functioning properly, how the program responds to
invalid data, test how changing one module will effect the whole system etc.. There are many
automated tools which can be used for comprehensive testing..
what are the factors contributing to the rise in global media Will .pdf
what are the factors contributing to the rise in global media? Will global media eventually
replace national media?
Solution
Q1) Media is the mass communication system of letting people informed through broadcasting,
publishing, and the internet. It enriches public awareness and knowledge, which is very
important in today’s fast moving world.
Global media gives the news of whole world, suppose a person sitting in India can get the
happenings in the US.
Factors are as below:
Point 1) The urge of national media: There are so many small national media in various
countries. They want to get international news as well but can’t get because of their small
infrastructure. Therefore, they are now becoming tied up with big international media agencies in
order to get regular updating. This is the reason of rising trend of global media.
Point 2) Globalization of economy: Most of the countries have free-trade environment now.
They need cheaper rate of factors of production (land, labor, capital, and organization); the
global media is a great source of information of it.
Point 3) Technological development: The development of internet gives the platform of rising of
global media. A person sitting on computer can get to know the whole world.
Q2) To some extent it is true. Since national media getting tied up with big global firms, the
chance of being acquired may be high in future. The small national media could be acquired by
those global media..

The diets common to some cultures emphasize meat. Meat, milk, and br.pdf
The diets common to some cultures emphasize meat. Meat, milk, and bread, but few fruits and
vegetables, might be a typical meal for populations in northern latitudes and in desert areas, for
example. What ecological factors seem relevant in explaining this human habit?
Solution
Various studies have shown that populations living in northern latitude and desert areas have
dietary patterns higher in animal fat such as meat and dairy products compared to those living in
southern latitudes who thrive majorly on fruits and vegetables. This may be because land in
northern and desert areas had been less fertile to grow seasonal vegeies, due to extremes of
environment and limited rainfalls. People living in these areas over generations have been mostly
hunter-gatherers. Such societies had depended for their economic survival primarily on hunting,
gathering (wild vegetable and fruits and small land fauna), and fishing. Thus they might have
developed the food habit of increased meat and milk consumption (as they are largely dependent
on herd of cattle/animals) along with staple diet of breads, over the generations.
On the other hand, southern populations residing on more fertile pieces of land relish a
vegetarian diet consisting of fresh fruits and vegetables. They are richer in biodiversity due to
moderate climates and rainfall distribution throughtout the year. These populations are typically
farmers, food growers over several generations and have developed food habits of vegetarian
diets..

Below is my program, I just have some issues when I want to check ou.pdf
Below is my program, I just have some issues when I want to check out a patient and when I
want to print a specific patient. Please help. I think there is a minor error, but I can\'t find it.
PATIENT ID MUST BE \"LASTNAMEFIRSTNAMEYEAR\" example PattersonMathew2005.
Please read instructions help me solve the problem.
In this assignment, you will write a struct plus two simple classes and then write a program
that uses them all. The first class is a Date class. You are given code for this at the end of this
assignment, but you must make some modifications. The other is a Patient class; you are given
the class definition and you must write the implementation. The program will keep track of
patients at a walk-in clinic. For each patient, the clinic keeps a record of all procedures done.
This is a good candidate for a class, but to simplify the assignment, we will make a procedure
into a struct. We will assume that the clinic has assigned all care providers (doctors, nurses, lab
technicians) with IDs and each procedure (“office visit”, “physical exam”, “blood sample taken”,
etc.) also has an ID. Each patient will also have an ID, which is formed by the last name
concatenated with the first name and the year of birth. All other IDs (care providers, procedures)
will be just integers.
When the user runs the program at the start of the day, it first tries to read in from a binary file
calledCurrentPatients.dat. It will contain the number of patients(in binary format) followed by
binary copies of records for the patients at the clinic . This information should be read and stored
in an array of Patient objects. There will be a separate array, initially empty at the start of the
program that will store patient records for all patients who are currently checked in at the clinic.
It then asks the user to enter the current date and reads it in. It should then presents the user with
a simple menu: the letter N to check in a new patient, R for checking in a returning patient, O to
check out a patient, I to print out information on a particular patient, P to print the list of patients
who have checked in, but not yet checked out, and Q for quitting the program.
The following tasks are done when the appropriate letter is chosen.
N: The new patient’s first name, last name, and birthdate are asked for and entered. The new
patient ID will be the last name concatenated with the first name and the year of birth. (Example:
SmithJohn1998) The primary doctor’s ID is also entered. The new patient object is placed in
both arrays: one keeping all patients, and one keeping the patients who checked in today.
R: The returning patient’s ID is asked for, and the array holding all patients is searched for the
patient object. If found, a copy of the patient object is placed in the array for all currently
checked in patients. If not found, the user is returned to the main menu after asking them to
either try R again, making sure the correct ID was entered, or choose N to enter th.
Alice uses a biased coin to create a one-time pad to encrypt a messa.pdf
Alice uses a biased coin to create a one-time pad to encrypt a message m of 1 bit. The coin
comes up 1 (Heads) 60% of the times and 0 (Tails) 40% of the times. Alice sends 0 as a message
75% of the times and 1 as a message 25% of the times. All of this is publicly known. Eve sees
cipher c = 1. What was the probability that m = 1?
Solution
An encryption scheme (E, D) is perfectly secret if there for every set M {0, 1} ` of plaintexts,
and for every strategy used by Eve, if we choose at random m M and a random key k {0, 1} n,
then the probability that Eve guesses m after seeing Ek(m) is at most 1/|M|.
In particular, if we encrypt either “Yes” or “No” with probability 1/2, then Eve won’t be able to
guess which one it is with probability better than half. In fact, that turns out to be the heart of the
matter:
Two to Many Theorem: An encryption scheme (E, D) is perfectly secret if and only if for every
two distinct plaintexts {m0, m1} {0, 1} ` and every strategy used by Eve, if we choose at
random b {0, 1} and a random key k {0, 1} n, then the probability that Eve guesses mb after
seeing Ek(mb) is at most 1/2.
Proof: The “only if” direction is obvious— this condition is a special case of the perfect secrecy
condition for a set m of size 2
The “if” direction is trickier. We need to show that if there is some set M (of size possibly much
larger than 2) and some strategy for Eve to guess (based on the ciphertext) a plaintext chosen
from M with probability larger than 1/|M|, then there is also some set M0 of size two and a
strategy Eve0 for Eve to guess a plaintext chosen from M0 with probability larger than 1/2.
Let’s fix the message m0 for example to be the all zeroes message. Since Eve(Ek(m0)) is a fixed
string, if we pick a random m1 from M then it holds that
Pr[Eve(Ek(m0)) = m1] 1/|M|
while under our assumption, on average it holds that
Pr[Eve(Ek(m1)) = m1] > 1/|M|
Thus in particular, due to linearity of expectation, there exists some m1 satisfying
Pr[Eve(Ek(m1)) = m1] > Pr[Eve(Ek(m0)) = m1] .
But this can be turned into an attacker Eve0 such that the probability that Eve0 (Ek(mb)) = mb is
larger than 1/2. Indeed, we can define Eve0 (c) to output m1 if Eve(c) = m1 and otherwise output
a random message in {m0, m1}. The probability that Eve0 (c) equals m1 is higher when c =
Ek(m1) than when c = Ek(m0), and since Eve0 outputs either m0 or m1, this means that the
probability that Eve0 (Ek(mb)) = mb is larger than 1/2 (Can you see why?) QED.
Exercise: Another equivalent condition for perfect secrecy is the following: (E, D) is perfectly
secret if for every plaintexts m, m0 {0, 1} ` , the two random variables {Ek(m)} and {Ek0 (m0
)} (for randomly chosen keys k and k 0 ) have precisely the same distribution.
So, perfect secrecy is a natural condition, and does not seem to be too weak for applications, but
can it actually be achieved? After all, the condition that two different plaintexts are mapped to
the same distribution seems somewhat at odds with th.
A paleontologist is studying the history of group of stratigraphic fo.pdf
A paleontologist is studying the history of group of stratigraphic fossils the arthropods. Use the
diagram below to answer the questions. The pictures of the organisms represent of two different
species that your research team has assigned to the various stratigraphic layers. Which of the
fossils has been assigned to the wrong layer? The paleontologist\'s graduate student was unsure
which rock layer was the most in important to date so she dated all of them with the results as
follows: A: 100 mya, B: 50 mya, C: 10 mya, D: 300 mya When did species 1 go extinct? When
did species 2 go extinct? If found a non-fossilized organic sample in the soil above the rock
layers, how might my approach to determining its age be different than for the fossilized
remains?
Solution
a) Species in the igneous rock has been assigned to the wrong layer.
Because, Igneous rocks do not contain fossils as they form from the molten rocks. These rocks
form when the molten rocks become cools and eventually solidify.
Instead of this, fossils are generally found in sedimentary rocks which is formed in layers by the
depositing and pressing of sediments on top of each other.
b) i) species 1 went extinct after 100 million years.
ii) Species 2 went extinct after 50 million years.
c) If I found a non-fossilized organic sample in the soil above the rock layers then I can use
carbon dating or radiometric dating. It is the process of determining the percentage of the
radioactive isotope in the sample and using the half life data to ultimately determine the age of
the sample.
Basic data of radiocarbon dating-
Carbon 14 is an isotope of carbon which is naturally formed in the atmosphere. All plants and
animals when they are alive, have regular intake carbon. When an animal or plant dies it no
longer takes in carbon of any form. That plant or animal most often decays and its constituent
parts break down and are eaten by scavengers, or they decay, or are washed away etc. Instead of
these events if the animal or plant is encased in some sediment, or frozen, or desiccated, or
otherwise preserved quickly so that its structure and constituent parts are preserved. Scientists
have ways of counting the carbon 14 atoms in a sample and then they find out the total number
of carbon atoms and figure out how old the material is.
In this way fairly new organic material’s age is also determined..

Reliability and safety are related but distinct dependability attrib.pdf
Reliability and safety are related but distinct dependability attributes for software. Describe two
important distinctions between these attributes. Explain why it is possible for a reliable system to
be unsafe and vice versa.
Solution
Explain why it is possible for a reliable system to be unsafe and vice versa.?
ANS:------> Because If the specification does not explicitly exclude dangerous behavior then a
system can be reliable but unsafe.RELIABILITYSAFETY1) Reliability involves much more
than analyzing test results, estimating remaining faults, and modeling future failure
probabilities.1)safety optimizes system safety in the design, development, use, and maintenance
of software systems and their integration with safety-critical hardware systems in an operational
environment.2)Ensuring system reliability does not necessarily lead to system safety as
Reliability is concerned with meeting the system specification (the system \'shall\')2)Safety is
concerned with excluding the possibility of dangerous behavior (the system \'shall not\').

Short Answer
7. Describe the inheritance pattern(s) of blood types.
8. When studying a newly discovered flowering plant in Costa Rica, you collect data on its petal
color in an effort to determine how this trait may be inherited. You find that 852 flowers are red,
331 are white and 389 are yellow. What are the possible inheritance patterns, and how could you
definitely conclude which of these possibilities is the true mode of inheritance?
Solution
Wild type- wild type phenotype refers to characteristics that occurs naturally in a breeding
population.
Epistasis - it refers to a phenomena when one gene’s expression is dependent on the presence of
another gene(s), called the modifier gene.

Let\'s take an example of comb varieties in chicken
We have two pure breeds : wyandotte whose phenotype is a rose comb and brahmas having the
phenotype of a pea comb, when crossed with each other, they create a completely new phenotype
of a walnut comb. Let\'s look at the ratio:
Parental cross: rose comb x pea comb
F1 : all walnut combs
F2 : 9 walnut : 3 rose: 3peas : 1 single
Hence the ratio is 9:16
Under the restrictive or nonpermissive condition conditions, conditionally lethal mutants will
die.
Conditionally lethal mutants are those which have an allele that will make the survival of the
species difficult only in a specific condition.
True. for example if a mutation in a gene gives the species a particular characterisitc which has
97%penetrance, only 97% of those with the mutation will develop that characteristic and 3 %
will not.
True. multiple genes affect continuous traits. For such complex gene interactions, the traits are
influenced by environmental factors too. For example, height and skin color.

why is there an uneven distribution of photosystem 1 and 2 on the th.pdf
why is there an uneven distribution of photosystem 1 and 2 on the thylakoid membrane?
Solution
Photosynthesis is carried out by the cyanobacteria, plants involved the absorption of light and the
conversion of its energy into chemical energy. The photosynthetic apparatus is made up of 4
multiprotein complexes, which are asymmetrically embedded in the thyalkoid memberane. It is
the high structural and functional coordination between these 4 complexes, which enables the
efficient coupling of photosynthetic electron transfer and photophosphorylation.
The 4 complexes - Photosystem II (PSII), cytochrome b6f complex, PS I and the proton-ATP
synthase, are unevenly distributed between the 2 regions of the thylakoids. The PS II complex is
situated in the appressed grana-lamella region, the PS I and the ATP synthase complex are
located in the non-appressed stroma-lamella region.
Light driven electron transfer is intiated with the oxidation of water mole. by the PS II complex
and the reduction of quinones associated with the PS II complex. The electrons are then
transferred across the memberane to plastocyanin via the Cyt b6f complex. Plastocyanin is a
copper protein facing the lumen of the thylakoids, is the secondary electron donor of the PS I
complex. In the PS I the electron are translocated across the memberane to ferredoxin which
further transfers them to NADP+. The membrane potental and proton gradient resulting from this
photochemical electron transport provide the motive force required for the formation of ATP by
the ATP synthase.
The transport of electron against the electrical potential and the formation of ATP and NADPH
are made possible due to the unique ability of the thylakoids to absorb light energy. The 2
pigment complexes (PS II and PS I) are responsible for harvesting the light and performing the
charge separation across the thylakoid memberanes.
Photosytem II (PS II):
1. PS II is located at the inner surface the grana thyalkoid memberane
2. The photocentre is P680
3. Pigments absorb shorter wavelengths of light (<680nm)
4. Participates only in non cyclic photophosphorylation
5. It is associated with photolysis of water
6. Main functions are ATP synthesis and hydrolysis of water
Photosystem I (PS I)
1. PS I is located at the outer surface the grana thylakoid memberane
2. The photocentre is P700
3. Pigments absorb longer wavelength of light (>680nm)
4. Participates in cyclic and non-cyclic photophosphorylation
5. It is not associated with photolysis of water
6. Main function is ATP synthesis
This is the purpose the two photosystems (PS) are unevely distributed in thyalkoid memberane..

what are the factors contributing to the rise in global media? Will global media eventually
replace national media?
Solution
Q1) Media is the mass communication system of letting people informed through broadcasting,
publishing, and the internet. It enriches public awareness and knowledge, which is very
important in today’s fast moving world.
Global media gives the news of whole world, suppose a person sitting in India can get the
happenings in the US.
Factors are as below:
Point 1) The urge of national media: There are so many small national media in various
countries. They want to get international news as well but can’t get because of their small
infrastructure. Therefore, they are now becoming tied up with big international media agencies in
order to get regular updating. This is the reason of rising trend of global media.
Point 2) Globalization of economy: Most of the countries have free-trade environment now.
They need cheaper rate of factors of production (land, labor, capital, and organization); the
global media is a great source of information of it.
Point 3) Technological development: The development of internet gives the platform of rising of
global media. A person sitting on computer can get to know the whole world.
Q2) To some extent it is true. Since national media getting tied up with big global firms, the
chance of being acquired may be high in future. The small national media could be acquired by
those global media..

The diets common to some cultures emphasize meat. Meat, milk, and br.pdf
The diets common to some cultures emphasize meat. Meat, milk, and bread, but few fruits and
vegetables, might be a typical meal for populations in northern latitudes and in desert areas, for
example. What ecological factors seem relevant in explaining this human habit?
Solution
Various studies have shown that populations living in northern latitude and desert areas have
dietary patterns higher in animal fat such as meat and dairy products compared to those living in
southern latitudes who thrive majorly on fruits and vegetables. This may be because land in
northern and desert areas had been less fertile to grow seasonal vegeies, due to extremes of
environment and limited rainfalls. People living in these areas over generations have been mostly
hunter-gatherers. Such societies had depended for their economic survival primarily on hunting,
gathering (wild vegetable and fruits and small land fauna), and fishing. Thus they might have
developed the food habit of increased meat and milk consumption (as they are largely dependent
on herd of cattle/animals) along with staple diet of breads, over the generations.
On the other hand, southern populations residing on more fertile pieces of land relish a
vegetarian diet consisting of fresh fruits and vegetables. They are richer in biodiversity due to
moderate climates and rainfall distribution throughtout the year. These populations are typically
farmers, food growers over several generations and have developed food habits of vegetarian
diets..

Below is my program, I just have some issues when I want to check ou.pdf
Below is my program, I just have some issues when I want to check out a patient and when I
want to print a specific patient. Please help. I think there is a minor error, but I can\'t find it.
PATIENT ID MUST BE \"LASTNAMEFIRSTNAMEYEAR\" example PattersonMathew2005.
Please read instructions help me solve the problem.
In this assignment, you will write a struct plus two simple classes and then write a program
that uses them all. The first class is a Date class. You are given code for this at the end of this
assignment, but you must make some modifications. The other is a Patient class; you are given
the class definition and you must write the implementation. The program will keep track of
patients at a walk-in clinic. For each patient, the clinic keeps a record of all procedures done.
This is a good candidate for a class, but to simplify the assignment, we will make a procedure
into a struct. We will assume that the clinic has assigned all care providers (doctors, nurses, lab
technicians) with IDs and each procedure (“office visit”, “physical exam”, “blood sample taken”,
etc.) also has an ID. Each patient will also have an ID, which is formed by the last name
concatenated with the first name and the year of birth. All other IDs (care providers, procedures)
will be just integers.
When the user runs the program at the start of the day, it first tries to read in from a binary file
calledCurrentPatients.dat. It will contain the number of patients(in binary format) followed by
binary copies of records for the patients at the clinic . This information should be read and stored
in an array of Patient objects. There will be a separate array, initially empty at the start of the
program that will store patient records for all patients who are currently checked in at the clinic.
It then asks the user to enter the current date and reads it in. It should then presents the user with
a simple menu: the letter N to check in a new patient, R for checking in a returning patient, O to
check out a patient, I to print out information on a particular patient, P to print the list of patients
who have checked in, but not yet checked out, and Q for quitting the program.
The following tasks are done when the appropriate letter is chosen.
N: The new patient’s first name, last name, and birthdate are asked for and entered. The new
patient ID will be the last name concatenated with the first name and the year of birth. (Example:
SmithJohn1998) The primary doctor’s ID is also entered. The new patient object is placed in
both arrays: one keeping all patients, and one keeping the patients who checked in today.
R: The returning patient’s ID is asked for, and the array holding all patients is searched for the
patient object. If found, a copy of the patient object is placed in the array for all currently
checked in patients. If not found, the user is returned to the main menu after asking them to
either try R again, making sure the correct ID was entered, or choose N to enter th.
Alice uses a biased coin to create a one-time pad to encrypt a messa.pdf
Alice uses a biased coin to create a one-time pad to encrypt a message m of 1 bit. The coin
comes up 1 (Heads) 60% of the times and 0 (Tails) 40% of the times. Alice sends 0 as a message
75% of the times and 1 as a message 25% of the times. All of this is publicly known. Eve sees
cipher c = 1. What was the probability that m = 1?
Solution
An encryption scheme (E, D) is perfectly secret if there for every set M {0, 1} ` of plaintexts,
and for every strategy used by Eve, if we choose at random m M and a random key k {0, 1} n,
then the probability that Eve guesses m after seeing Ek(m) is at most 1/|M|.
In particular, if we encrypt either “Yes” or “No” with probability 1/2, then Eve won’t be able to
guess which one it is with probability better than half. In fact, that turns out to be the heart of the
matter:
Two to Many Theorem: An encryption scheme (E, D) is perfectly secret if and only if for every
two distinct plaintexts {m0, m1} {0, 1} ` and every strategy used by Eve, if we choose at
random b {0, 1} and a random key k {0, 1} n, then the probability that Eve guesses mb after
seeing Ek(mb) is at most 1/2.
Proof: The “only if” direction is obvious— this condition is a special case of the perfect secrecy
condition for a set m of size 2
The “if” direction is trickier. We need to show that if there is some set M (of size possibly much
larger than 2) and some strategy for Eve to guess (based on the ciphertext) a plaintext chosen
from M with probability larger than 1/|M|, then there is also some set M0 of size two and a
strategy Eve0 for Eve to guess a plaintext chosen from M0 with probability larger than 1/2.
Let’s fix the message m0 for example to be the all zeroes message. Since Eve(Ek(m0)) is a fixed
string, if we pick a random m1 from M then it holds that
Pr[Eve(Ek(m0)) = m1] 1/|M|
while under our assumption, on average it holds that
Pr[Eve(Ek(m1)) = m1] > 1/|M|
Thus in particular, due to linearity of expectation, there exists some m1 satisfying
Pr[Eve(Ek(m1)) = m1] > Pr[Eve(Ek(m0)) = m1] .
But this can be turned into an attacker Eve0 such that the probability that Eve0 (Ek(mb)) = mb is
larger than 1/2. Indeed, we can define Eve0 (c) to output m1 if Eve(c) = m1 and otherwise output
a random message in {m0, m1}. The probability that Eve0 (c) equals m1 is higher when c =
Ek(m1) than when c = Ek(m0), and since Eve0 outputs either m0 or m1, this means that the
probability that Eve0 (Ek(mb)) = mb is larger than 1/2 (Can you see why?) QED.
Exercise: Another equivalent condition for perfect secrecy is the following: (E, D) is perfectly
secret if for every plaintexts m, m0 {0, 1} ` , the two random variables {Ek(m)} and {Ek0 (m0
)} (for randomly chosen keys k and k 0 ) have precisely the same distribution.
So, perfect secrecy is a natural condition, and does not seem to be too weak for applications, but
can it actually be achieved? After all, the condition that two different plaintexts are mapped to
the same distribution seems somewhat at odds with th.
A paleontologist is studying the history of group of stratigraphic fo.pdf
A paleontologist is studying the history of group of stratigraphic fossils the arthropods. Use the
diagram below to answer the questions. The pictures of the organisms represent of two different
species that your research team has assigned to the various stratigraphic layers. Which of the
fossils has been assigned to the wrong layer? The paleontologist\'s graduate student was unsure
which rock layer was the most in important to date so she dated all of them with the results as
follows: A: 100 mya, B: 50 mya, C: 10 mya, D: 300 mya When did species 1 go extinct? When
did species 2 go extinct? If found a non-fossilized organic sample in the soil above the rock
layers, how might my approach to determining its age be different than for the fossilized
remains?
Solution
a) Species in the igneous rock has been assigned to the wrong layer.
Because, Igneous rocks do not contain fossils as they form from the molten rocks. These rocks
form when the molten rocks become cools and eventually solidify.
Instead of this, fossils are generally found in sedimentary rocks which is formed in layers by the
depositing and pressing of sediments on top of each other.
b) i) species 1 went extinct after 100 million years.
ii) Species 2 went extinct after 50 million years.
c) If I found a non-fossilized organic sample in the soil above the rock layers then I can use
carbon dating or radiometric dating. It is the process of determining the percentage of the
radioactive isotope in the sample and using the half life data to ultimately determine the age of
the sample.
Basic data of radiocarbon dating-
Carbon 14 is an isotope of carbon which is naturally formed in the atmosphere. All plants and
animals when they are alive, have regular intake carbon. When an animal or plant dies it no
longer takes in carbon of any form. That plant or animal most often decays and its constituent
parts break down and are eaten by scavengers, or they decay, or are washed away etc. Instead of
these events if the animal or plant is encased in some sediment, or frozen, or desiccated, or
otherwise preserved quickly so that its structure and constituent parts are preserved. Scientists
have ways of counting the carbon 14 atoms in a sample and then they find out the total number
of carbon atoms and figure out how old the material is.
In this way fairly new organic material’s age is also determined..

Reliability and safety are related but distinct dependability attrib.pdf
Reliability and safety are related but distinct dependability attributes for software. Describe two
important distinctions between these attributes. Explain why it is possible for a reliable system to
be unsafe and vice versa.
Solution
Explain why it is possible for a reliable system to be unsafe and vice versa.?
ANS:------> Because If the specification does not explicitly exclude dangerous behavior then a
system can be reliable but unsafe.RELIABILITYSAFETY1) Reliability involves much more
than analyzing test results, estimating remaining faults, and modeling future failure
probabilities.1)safety optimizes system safety in the design, development, use, and maintenance
of software systems and their integration with safety-critical hardware systems in an operational
environment.2)Ensuring system reliability does not necessarily lead to system safety as
Reliability is concerned with meeting the system specification (the system \'shall\')2)Safety is
concerned with excluding the possibility of dangerous behavior (the system \'shall not\').

Wild type- wild type phenotype refers to characteristics that occurs naturally in a breeding
population.
Epistasis - it refers to a phenomena when one gene’s expression is dependent on the presence of
another gene(s), called the modifier gene.
9:16
Let\'s take an example of comb varieties in chicken
We have two pure breeds : wyandotte whose phenotype is a rose comb and brahmas having the
phenotype of a pea comb, when crossed with each other, they create a completely new phenotype
of a walnut comb. Let\'s look at the ratio:
Parental cross: rose comb x pea comb
F1 : all walnut combs
F2 : 9 walnut : 3 rose: 3peas : 1 single
Hence the ratio is 9:16
Under the restrictive or nonpermissive condition conditions, conditionally lethal mutants will
die.
Conditionally lethal mutants are those which have an allele that will make the survival of the
species difficult only in a specific condition.
True. for example if a mutation in a gene gives the species a particular characterisitc which has
97%penetrance, only 97% of those with the mutation will develop that characteristic and 3 %
will not.
True. multiple genes affect continuous traits. For such complex gene interactions, the traits are
influenced by environmental factors too. For example, height and skin color.
There are four basic blood types which are A, B, AB and O and together with the Rh factor,
these can be +ve or -ve.
A and B are dominant, while O is recessive.

For Rh factor, Rh (+)ve is dominant.
So if the any one or both parents have Rh (+)ve factor, the progeny will be Rh(+)ve.
If both parents are Rh(-)ve, the progeny will be Rh (-)ve

Red: 852
White: 331
Yellow:389
According to the given data, red is dominant and white is recessive and yellow is a result of
incomplete dominance of both white and red phenotype.
It can\'t be codominance, because codominance involves both phenotypes being expressed in
di.

Embracing GenAI - A Strategic Imperative
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
