Why is water a more hospitable environment for life than dry land? Osmotic balance is not a
problem Gravity is not a problem. Sperm can meet egg easily in water. Oxygen is more
available in water. B and C only. Angiosperms disperse their seeds by producing seeds. Fleshy
edible fruits that are consumed by animals which defecate the Seeds that sometimes attach to
animals. Seeds that catch the wind. All of the choices are correct. None of the choices are
correct. Tracheal system for gas exchange is found in which organism? Crustacean Earthworm.
Insect. Jellyfish. Vertebrate What is a radula? A flexible supportive rod on the dorsal surface
of chordates. A stinging cell used by sea anemones to capture prey. A locomotory structure in
sea stars. A spiny ribbon of tissues used for feeding in snails. A gas exchange structure in
insects. Which of the following adaptations allowed reptiles to complete their life cycles on
land? Lungs. Endothermic metabolism. An amniotic egg. Four legs. Pack behavior. What
class of the phylum Cnidarian occurs only as a polyp? Hydrozoa. Scyphozoan. Anthozoa.
Only A are correct. A, B, and Care correct.
Solution
The third option is correct. Water is a good source for pollination or spreading of gametes.
The option D is correct. Angiosperms are evolved advanced and have various types of
pollination system. This helps the greater availability of them.
The option C is correct. Insects have advance type of tracheal based respiratory system.
The option D is correct. Radula is a hard anatomical structure used for feeding by scraping or
cutting food. This is characteristic of Mollusca phylum.
The option A is correct. Lungs are importantly developed in reptiles to live in land.
The option D is correct. Hydrozoa a class of Cnidaria are always polyp..

Amphibians, as their name indicates, they can spend “double life” bo.pdfpreetajain
Amphibians, as their name indicates, they can spend “double life” both in water and on earth.
The respiratory organs skin, gills and lungs are the characteristic adaptations of these animals.
However, during evolution they adopted to live on land though they spend also in water.
Three organs/organ systems that appear relatively early on from embryo-organogenesis:
Notochord formation
Neural tube formation
Spemanns organizer
Gills
Fate of each adult: Initialy notochor is primary organ system develops to support skeletal
arrangement
Adaptive change
Amphibians
Respiration
During larval life, amphibians have gills, which disappear as they grow and they respire through
the moist skin in water and through lungs on lands
Reproduction
Amphibians lay eggs in water as they need moist environment for hatching, and the adults can
live on land.
Circulation
Amphibians have double loop circulation. The heart is equipped with three chambers and there is
some mixing of oxygenated blood with deoxygenated blood.
Feeding
Amphibians mostly live on small aquatic plants and animals, and small insects on land. Most of
the amphibians are carnivores.
Excretion
Amphibians excrete their wastes through the kidneys. They excrete ammonia through the urine
directly into the surrounding environment.
Response
These have well developed sensory and nervous systems. The eyes of amphibians are protected
by nictitating membrane, that provide protection in water and they hear through tympanic
membrane, located at the side of the head.
Amphibian gastrulation always initiates with invagination of the embryonic bottle cells followed
by involution of mesoderm and finally epiboly of ectoderm.
In frog, gastrulation starts on the dorsal side of the blastula, a group of cells invaginate and form
a crease, along the region of where grey crescent is formed. The part above this crease becomes
dorsal lip (dorsal side of the blastospore). In case of frogs (vertebrates), organizer region is
become a “dorsal lip” of developing blastophore during gastrulation finally “this embryonic
organizer enable formation of blastula by modifying genetic expression of cells moving past the
organizer.
During gastrulation process, involution of endoderm and mesoderm occurs from “embryonic
organizer”. Once inside the embryo, then these cells moves toward the animal pole (in the figure,
the upper pole is animal pole, and the lower pole is vegetal pole) and organized into layers of
endoderm and mesoderm. Blastocoel is the central cavity of blastula; it is present in the animal
hemisphere in frog embryo.

expelcit knowledge can be trasfered to other easily, what ever we knows and want to share others
we can. we can write it, we can speak it and we can draw it and make the opposite understand it.
on the other hand tacit knowledge is intuitive and unarticulated knowledge that cannot be
communicated, understood or used without the ‘knowing subject’. to understand this the subject
knowledge is required to the opposit people.
explecit knowledge can be learned by formal education, logical thinking and practical

How did printing technology impact literacy and education How d.pdfarihantkitchenmart
How did printing technology impact literacy and education ?
How did printing technology impact literacy and education ?
Solution
Print culture embodies all forms of printed text and other printed forms of Visual
Communication. One prominent scholar in the field is Elizabeth Eisenstein, who contrasted print
culture, which appeared in Europe in the centuries after the advent of the Western printing press
to scribal culture.
Print culture is the conglomeration of effects on human society that is created by making printed
forms of communication. Print culture encompasses many stages as it has evolved in response to
technological advances. Print culture can first be studied from the period of time involving the
gradual movement from oration to script as it is the basis for print culture. As the printing
became commonplace, script became insufficient and printed documents were mass produced.
The era of physical print has had a lasting effect on human culture, but with the advent of digital
text, some scholars believe the printed word is becoming obsolete.
The advent of the printing press over five hundred years ago may be described as one of the few
major significant events in mankind’s history in terms of the greatest impact on literacy. Before
paper and print were invented, oral communication was the only method in which information
was gathered and distributed. Even though this bound the community together, it did not allow
the community to grow and there were no methods of accurately storing and retrieving
information. Further, if the community moved on or perished so did their historical records and
knowledge. Although the following technologies involved the written word in the form of
papyrus scrolls and manuscript codex as examples, it was still quite time consuming and limited
to the upper literate elite class of society. When the printing press was invented there was a shift
from the laborious manuscript making to the codex print allowing many copies of written work
to be quickly created, in turn providing greater access to information for all and providing the
framework for the gradual transformation of societal literacy.
The concept of printing was first conceived and developed in China and Korea. Although the
concept was conceived by the eastern nations, the first mechanized printing press was invented
by a German metalworker named Johann Gutenberg in 1452. Gutenberg did not invent the
printing press but rather conceived the idea of movable type which is actually an aggregation of
three distinct technologies utilized by humans for many centuries before Gutenberg (Jones
2007). This can be described as a form of remediation of previous communication technologies.
Bolter defines remediation when a, “newer medium takes place of an older one, borrowing and
reorganizing the characteristics of writing in the older medium and reforming its cultural space.”
(Bolter, 2001, p.23). Gutenberg combined the technologies of paper, viscous oil-based ink.

Applying change management theoryto discuss the integration ofone of.pdfarihantkitchenmart
Applying change management theoryto discuss the integration ofone of the four types of
knowledge-based decision support systems
Solution
Change management and knowledge-based decision support systems to my mind are supposed to
play both supplementary and complementry roles in the development of decision making process
in almost all types of the organizations.
With the development of computers and emergence of Data based Management System
(DBMS), very many companies/ organizations underwent changes during 1950 and 1970 but
mostly at the lower level of management to cope up with the incresed level of transactions and
the subsequent couple of decades with the success of Decision Supports Systems (DSS) and
increasing use of internet forced the middle level management to pay attention to the crucial role
of Information Technology and its impact on the theories of change management. Middle level
of management has popularised the terms Executive information Systems (EIS), Management
Information Systems (MIS and Experts Systems (ES).
Currently all levels of management including top level management who is more resposible for
strategic planning, are talking about all types of knowledge-based decision support systems to be
integrated in so called Enterprise Resources Planning Systems (ERP).
The introduction of ERP, the ultimate of integration of all activities, tasks, procedures, processes,
rules regulations etc calls upon the Change management theories to come into play for the
success of ERP. It is required because ERP needs not only the integration of knowledge-based
decision support systems but being very much dynamic in nature needs change management
theories for its implementation..

Albinism in humans is inherited as a simple recessive trait. For the following families, determine
the most likely genotypes of the parents. A normal male and an albino female have six children,
three normal and three albino. What are the most likely genotypes of the parents?
a.male AA; female aa
b.male AA; female Aa
c.male Aa; female aa
d.male Aa; female Aa
Solution
c.male Aa; female aa
Albinism is a homozygous recessive trait. Assume that the gene coding for normal phenotype is
A and the gene coding for albinism is a (A is normal and A is dominant over a), albinism is
inherited by a homozygous recessive pattern (aa).
It is given that an unaffected male and an affected female had both normal and affected children.
Means, the children receive one recessive allele from the mother and the other from the father.
Thus, the father is heterozygous (Aa) and the mother is homozygous recessive (aa)..

Solution
BILATERAL SYMMETRY-The evolutionary significance of it is , bilateral symmetry is a
feature of most of the vertebrae. bilateral symmetry contribute to the development of complex
central nervous system such as spinal cord and vast network of nerves in the brain. it also help in
sensory organ development. this characters make us superior from other species.
CEPHALIZATION- THE evolutionary significance of it is the development of brain which
becomes more complex and co-ordinated. other advantage is, thevconcentration of sense organs
at the front of the body and the close proximity of the mouth to sense organs.
TRIPLOBLASTY- the germ layers are evidence of slowly adapting layersof developmental

What are transposons How have they been exploited for bacterial gen.pdfarihantkitchenmart
What are transposons? How have they been exploited for bacterial genetic research?
Solution
The discrete genetic elements of pathogens such as bacteriophages, \"transposons\" & conjugate
plasmids that integrated into the host cell genome via horizontal gene transfer finally become
more recombinant to generate virulence of pathogen. The hypothesis of this phenomenon is to
acquire higher resistance towards host defense system by increasing “pathogen virulence factor
synthesis”. This acquisition of genomic integration of conjugate plasmid or “transposon” is
useful to obtain knowledge about the pathogen nature & pathogen interaction with host cell
finally enables to synthesize vaccines via bacterial genetic research etc.
Horizontal gene transfer takes place between bacteria by transferring plasmids and transposons
to transfer both pathogenicity and antibiotic resistance properties carrying genes to non-
pathogenic, antibiotic-susceptible bacteria..

Southern, Eastern, Western, and Central populations. Each new population consisted of about
200 individuals. The five populations continued to evolve, and n migration occurred among
populations. One hundred generations later, each population still has about 200 individuals, and a
biology Each population would probably have fewer allies that is, versions of gones than it
would have had 100 generations ago. Agree Disagree Each population would probably gain
new mutations through genetic drift. Agree Desagree Would\'s biologist agree ordisagree with
the following statements In the smaller populations of 20 individuals, the processes leading to
genetic crift could have a stroger influence on a gene than natural selection Agree Disagree
Chance survical of some individulas occurmed in some generations, but no every generation.
Agree Disagree All species of during beetles lay their eggs in bells in during Long lege allow
the beetles to create better during balls which improves reproductive success. Long legs were
common before the canals were bult. However, after the populations were separated became less
common in the most southern population. Would the biologist agree or disagree with the
following explanations An increase in the proportion of beetles with short legs occurred because
natural selection favored individuals with shorter legs. Agree Disagree Since there was no
migration there could be no genetic drift. Agree Disagree A disorder that causes
nearsightedness is caused by a genetic multaion. Nearsighledness was harmful to people living
on a small island because the island. Before the storm, 0.1 % of the people had this disorder. Of
the 50 people who survived the storm, 2% were nearshigted. Within a few generations, 10% of
the islanders were nearsighted. Nearsightedness must have become more common thought
natural selection. Agree Disagree Near-sightedness must have become more common though
people migrating from neighboring islands. Agree Disagree Nearsighledriess must common
through migrating from neighboring islards. Agree Disagree Nearsighteclness must have
become more common through new mutations. Agree Disagree
Solution
Answer 12- Agreed to this statement as greater variation will occur due to mutation, climatic and
environmental changes over a long period of time. So only few adaptic variation were found
among five population.
Answer 13-Agreed . Yes number of alleles will remain same .
Answer 14-Agreed. Variation may occur through long time gap. Genetic drift will cause
mutation and result in variation among 5 population.
Answer 15- Agreed. As genetic drift will have more influence than natural selection as it a
slower process than genitic drift.
Answer 16- Agreed. Similar features existed among these population , so number of death of
individual remai.

Why do some elderly take B12 sublingually or transdermally Provide .pdfarihantkitchenmart
Why do some elderly take B12 sublingually or transdermally? Provide a detailed answer with
research to back it up. Cite your source.
Solution
The oral route of administration of vitamin -B12 (cynacobalamin) has poor absorption rates in
older senior citizens during the treatment of pernicious anemia whereas intramuscular route of
administration is going to cause severe pain finally inflammation or wound, which is likely take
longer time to heal (if they have diabetes). So that it is essential to provide them sublingual
tablets or transdermal B12 patches to provide them a better absorption into direct \"blood
transport\". This is because sublingual route has associated with direct exposure of blood
capillaries so that promotes easy absorption.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
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.

Why is water a more hospitable environment for life than dry land O.pdf
1. Why is water a more hospitable environment for life than dry land? Osmotic balance is not a
problem Gravity is not a problem. Sperm can meet egg easily in water. Oxygen is more
available in water. B and C only. Angiosperms disperse their seeds by producing seeds. Fleshy
edible fruits that are consumed by animals which defecate the Seeds that sometimes attach to
animals. Seeds that catch the wind. All of the choices are correct. None of the choices are
correct. Tracheal system for gas exchange is found in which organism? Crustacean Earthworm.
Insect. Jellyfish. Vertebrate What is a radula? A flexible supportive rod on the dorsal surface
of chordates. A stinging cell used by sea anemones to capture prey. A locomotory structure in
sea stars. A spiny ribbon of tissues used for feeding in snails. A gas exchange structure in
insects. Which of the following adaptations allowed reptiles to complete their life cycles on
land? Lungs. Endothermic metabolism. An amniotic egg. Four legs. Pack behavior. What
class of the phylum Cnidarian occurs only as a polyp? Hydrozoa. Scyphozoan. Anthozoa.
Only A are correct. A, B, and Care correct.
Solution
The third option is correct. Water is a good source for pollination or spreading of gametes.
The option D is correct. Angiosperms are evolved advanced and have various types of
pollination system. This helps the greater availability of them.
The option C is correct. Insects have advance type of tracheal based respiratory system.
The option D is correct. Radula is a hard anatomical structure used for feeding by scraping or
cutting food. This is characteristic of Mollusca phylum.
The option A is correct. Lungs are importantly developed in reptiles to live in land.
The option D is correct. Hydrozoa a class of Cnidaria are always polyp.
