1. Describe how plant vasculature is optimized for water transport in the tallest trees
2. What property of water molecules allow water to stay together while being transported to
extreme heights? And how does temperature affect this?
3.Water and minerals enter the plant through _______, and are then transported through plant\'s
vasculature, via the _________. This flow is maintained through constant ________, where
water exists through __________ in the leaves. The sugars that are made during photosynthesis
in the ____________ are transported downwards through the vasculature via the _______.
4. Give an example of ways plant have evolved to cope with drought,
Solution
Water transport in tree occurs by cappilary action .Water is trasported by root to leaves through
xylem . xylem is made up by tube like cells tracheids and vessel . These join together from root
to leaves . Two forces are usful to flow water upward 1. root pressure and 2. transpiration . Root
pressure occure when water flow into root due to osmotic pressure . Transpiration occures due to
evoporation from leaf surface . The adhesive nature of water molecules to inner cappilary wall
help to keep water column against gravitational force .
2 Adhesive nature of water to inner cappilary wall . Temprature increases transpiration and low
osmatic pressure in leaves .
3. water and mineral entered the plant through ROOT and are then trasported through plant
vasculature , via the XYLEM These flow is maintained through constant TRANSPIRATION
where water exist through STOMETA in the leaves . Thesuger that are made during
photosynthesis in the leaf are transported downward through the vasculature via PHLOEM.
4 Plant have evolved to cope with drought as xerophytic plant have well develop root system ,
fleshy leaves and stometa sunk in fleshy leave to avoid tranpiration ..
Conduction of water in plants is less elaborate than that of animal as well as plants. Plants are less active, so their cells do not need quick supply of materials. So, the only substances which are to be supplied to a plant through vascular bundle are water and minerals, this process is called ascent of sap. These materials are not available from air. Transport system also helps to carry food prepared in the leaves to the various parts of the plant like stems , roots etc. Ascent of sap is executed by two types of vascular bundles: Xylem which transports water and Phloem which transports prepared food.

Which of the following characteristics of living organisms absolutely disqualifies viruses as
alive?
A. Reproduction
B. Ability to move
C. Utilizing energy
D. Evolutionary adaptation
E. Cellular organization
Solution
A. Reproduction is characteristic that disqualifies viruses as alive; as for this they are dependent
on other living cells. They can reproduce on their own. for ex. a bacteriophage infects a bacterial
cell by injecting its DNA to bacterial cell. when that piece of viral DNA gets replicated with
bacterial DNA, the bacterial cell expresses all viral genes which are necessary to make new viral
cells, on getting them mature the bacterial cell brusts to release those viral cells. thus a life of
viruse is dependent on a other living cell for reproduction..

Problem asks me to prove Uniqueness but Im not sure how to do it! .pdfmohamednihalshahru
Problem asks me to prove Uniqueness but I\'m not sure how to do it! From my ODE\'s and

Solution
Uniqueness arguments are identical for both both problems (in general, for this category of
equations):
Let u and v are two solutions satisfying (the reduced Helmholtz) equations ) an elliptic equation
and the boundary conditons (Dirichlet and Neumann).
By linearlity u-v satisfies the elliptic equation with boundary conditions zero.
Applying the maximum principle to u-v yields u-v =0 throughout. Hence the uniqueness..

Examine your opinion on the death penalty. Defend why you are for the death penalty or against
it. Be sure to be specific in your defense on your stance.
Solution
Death penalty or execution is govt. sanctioned punishment by death.Iam in favour of death
penalty as:-
1.) Detterent to crime:- Death penalty is given to criminals who do first degree crimes ike murder
, terrorism and espionage.It produces a strong detterent effect on crime and criminals.
2) Fear of death:- Though death is inevitable we all still fear it. Imposing death punishment for
brutal crimes like rapes and murders will definately make the criminal think twice before
committing a crime.
3) No escape:- A criminal murderer or serial killer can escape imprisonment in the long run
leading to more crime and threat to society.. Death penalty puts an end to crime.
4) Saves lifes:- Death penalty produces a strong detterent effect on crime and criminals and
hence saves lifes..
Do you think that knowing about aggression between groups of chimpan.pdfmohamednihalshahru
Do you think that knowing about aggression between groups of chimpanzees is useful in
understanding conflicts between human societies? Why or why not?
Solution
In many primates where the range is small , contact with one or more groups of the same species
is a very common feature. However the nature of these encounters varies from species to species.
Primate groups remain permanently in a specific locality which is described as there home range.
Members of the same group exist in this range however it is not necessary that the individuals of
the group should remain in the same range but may change over to other ranges and join a new
community.
This home range consists of a central core area with highest concentration of the predictable
resources and represent the region where the group is more likely to be found.It also represents
the territory of the group which is defended against intrusion. There may be overlapping of the
home range between the groups but not the core area.
Territoriality is a behavior exhibited by many primates to protect their home range. This is seen
extensively where the home ranges are small and permits patrolling and protection of the
territory.
Biological continuum refers to the fact that the organisms are related through common ancestry
and the behavioral traits seen in one organisms are seen in others also but in varying degrees.
The man is considered to be a highly evolved social organism with a huge brain and thinking
capacity. He is more related to chimpanzees and the main difference between us and the other
primates is that the difference in behavior is merely quantitative and not qualitative.
Interactions between groups of chimpanzees include aggression, display chasing and sometimes
violent fighters also. Male chimpanzees are highly intolerable to unfamiliar chimpanzees,
specially males and aggressively defend their territories and resources.
Lethal aggression is a common feature among the chimpanzees. It is common in groups of male
chimpanzees which do patrolling around their territory. Sometimes they are also accompanied by
one or two females. During this patrolling, they exhibit silent movement, stop frequently, sniff
around and climb tall trees and sit on them for hours together to survey the area. They appear to
be tense during such situations and any sudden sound causes them to exhibit nervous behavior
like touching each other for reassurance or embrace each other.
When they encounter members of another community, They exhibit some form of aggression till
the other group retreats. Chimpanzees are also known to exhibit cruelty, and aggression
combined with compassion, tenderness and altruism which is comparable to human behavior, but
the main difference is that chimpanzees are not aware of the suffering they inflict on others while
humans do. Thus, the behavior of chimpanzees can be more related to human behavior, but the
difference lies in quantitative than qualitative.
Diana’s Death UnraveledHemophilia causes a lack of blood clotting,.pdfmohamednihalshahru
Diana’s Death Unraveled
Hemophilia causes a lack of blood clotting, but Diana died from overactive blood clotting. Factor
V Leiden is the most common hereditary hypercoagulability disorder amongst Eurasians. About
5% of Caucasians in North America are affected, and it is inherited as an autosomal dominant
mutation that causes high levels of clotting Factor V. It can cause deep vein thrombosis (blood
clot in the vein), pain, life-threatening strokes, and heart attacks.
1. Based on the types of mutations we’ve discussed so far in class, which does Factor V Leiden
fall into? (1pt)
2. Kevin Keller’s aunt’s husband and his girl cousin have died of heart attacks, but his mother,
sister, and brother are fine. Lisa Keller’s uncle is fine, but her aunt had multiple miscarriages
before she died. Her mother suffered from deep vein thrombosis, and her grandfather died of a
heart attack. Recall that Lisa has a brother with hemophilia C and an unaffected sister. Create a
pedigree diagramming these relationships. (3 pts)
b. Who do you think is more likely to carry the Factor V Leiden mutation? (1 pt)
a. Kevin Keller
b. Lisa Keller
c. Both
c. What do you think happened with the Morrison’s and Keller’s when Olivia and Diana were
young? (2 pt)
3. There is enough research evidence to support phenotypic changes in hemophiliacs with Factor
V Leiden mutations. Based on what we’ve discussed in chapter 4, what are some suggestions as
to why this might happen? Be sure to describe the normal symptoms of hemophilia and how
protein levels are affected to support your answer. (3pts)
Solution
1. Missense substitution mutation leads to Factor V Leiden . The gene which codes to the factor
is F5. A mutation of this gene where Guanine is substituted by Adenine which results in the
changing of amino acid Arginine to Glutamine.
I am not sure of the answers for the remaining questions. Please post those questions again for
other experts to answer. Thank you..

d) 2!T*d (00-10)
e) 9g&8tY7#?s+445=232+
Solution
Answers:
1)How do the viruses propagate between computers?
-> The browsers gain more features and functions more methods for virus propagation appear
directly to a computer across the network.
Web pages :
->Either via a download, web code, or a cross-site scripting (CSS) attack, web pages can be a
source of viral infection. As browsers gain more features and functions more methods for virus
propagation appear.
Messages:
-> E-mail messages as well as IM or chat messages can be a vector for viral infection.
-> Whether the virus is spread through links, embedded code, or an attachment depends on the
type of message and the client software.
Infected programs or Trojans :
-> Running an infected program that you copied from a CD or other media (or downloaded) is a
means of infection. Sometimes the virus is a Trojan, where it appears to be a useful program, but
is in fact a virus.
2. What is social engineering?
-> Social engineering is an attack vector that relies heavily on human interaction and often
involves tricking people into breaking normal security procedures.
-> Social engineering is the art of manipulating people so they give up confidential information.
-> A social engineer runs what used to be called a \"con game.
Popular types of social engineering attacks :
1)Phishing:
-> Phishing is when a malicious party sends a fraudulent email disguised as a legitimate email,
often purporting to be from a trusted source.
2) Pretexting:
->Pretexting is another form of social engineering where attackers focus on creating a good
pretext, or a fabricated scenario, that they can use to try and steal their victims’ personal
information.
3. How will an SPI firewall handle a packet containing a TCP segment which is an
acknowledgement?
-->Process it through the Access Control List (ACL)
-> Stateful Packet Inspection: Connections have distinct states or stages.
->Different states are subject to different attacks. Stateful firewalls use different filtering rules
for different states. Different because it uses filter rules in order to accept or deny traffic.
->An example would be windows firewall.
4. Revise the access control list (ACL) in Figure 3-23 (page 119 in.
Briefly describe the two competing theories regarding the origin of H.pdfmohamednihalshahru
Briefly describe the two competing theories regarding the origin of Homo sapiens and its
distributional expansion from its origin in Africa. What does the genetic data say about these
two hypothesis, which genes are most useful for these analyses and why? Given a large section
of a genome, say a complete chromosome, how could you locate genes? Given a large section of
a gene, say a complete exon, how could you determine reading frame?
Solution
1. There are many competing therapies for the origin of Homo sapiens. Two such theories are
Multi-regional hypothesis and Out of Africa 2 model.
Multi-regional Hypothesis: The multi-regional hypothesis argues that our early hominid
ancestors, including Homo ergaster and Homo heidelbergensis, migrated out of Africa and thus
the evolution of modern humans took place in different parts of the world, a process termed
regional continuity. This theory places great emphasis on the notion of steady evolutionary
alterations or changes that happen in different regions and produce diverse variations of the
species. Evolution of this kind is kept at a regular rate due to an amalgamation of cultural
progress and ‘gene flow’ or interbreeding, thus keeping all lineages evolving at the same time.
This process is characterized as parallel evolution, which suggests a subtle morphological
resemblance between populations of species who are geographically separated.
Out of Africa 2 model: It is widely recognized among both archaeological and anthropological
academics that archaic Homo populations did leave Africa in an initial phase of globalisation,
called the Out of Africa 1 model. Following this, the population replacement hypothesis
maintains that modern humans evolved in Africa from the ancestral hominids that did not travel
out of this continent in the first stage of global colonisation. It is then argued in this model that
once evolved as anatomically modern humans, Homo sapiens travelled out of Africa to explore,
colonise and rapidly replace the archaic Homo population. This movement suggests a second
wave of hominid species emerging from Africa, thus the title: the Out of Africa 2 model..

A Strategic Approach: GenAI in EducationPeter Windle
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.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

1. Describe how plant vasculature is optimized for water transport i.pdf
1. 1. Describe how plant vasculature is optimized for water transport in the tallest trees
2. What property of water molecules allow water to stay together while being transported to
extreme heights? And how does temperature affect this?
3.Water and minerals enter the plant through _______, and are then transported through plant's
vasculature, via the _________. This flow is maintained through constant ________, where
water exists through __________ in the leaves. The sugars that are made during photosynthesis
in the ____________ are transported downwards through the vasculature via the _______.
4. Give an example of ways plant have evolved to cope with drought,
Solution
Water transport in tree occurs by cappilary action .Water is trasported by root to leaves through
xylem . xylem is made up by tube like cells tracheids and vessel . These join together from root
to leaves . Two forces are usful to flow water upward 1. root pressure and 2. transpiration . Root
pressure occure when water flow into root due to osmotic pressure . Transpiration occures due to
evoporation from leaf surface . The adhesive nature of water molecules to inner cappilary wall
help to keep water column against gravitational force .
2 Adhesive nature of water to inner cappilary wall . Temprature increases transpiration and low
osmatic pressure in leaves .
3. water and mineral entered the plant through ROOT and are then trasported through plant
vasculature , via the XYLEM These flow is maintained through constant TRANSPIRATION
where water exist through STOMETA in the leaves . Thesuger that are made during
photosynthesis in the leaf are transported downward through the vasculature via PHLOEM.
4 Plant have evolved to cope with drought as xerophytic plant have well develop root system ,
fleshy leaves and stometa sunk in fleshy leave to avoid tranpiration .
