There are many types of malwares like Trojans, viruses, worms, rootkits, and many more We will here discuss about viruses and worms Viruses are the programs that gets themselves replicated itself and gets into other files and programs and destroys data or makes the file damaged so that the file becomes corrupt or damaged. Whenever the user tries to open the infected files virus gets spread in other files. Worms are self-activated programs. They spreads over the networks and infect the other computers in the network without user’s knowledge and permission and sends the data of one system to others.

Two types of malware -1. Virus A virus is a contagious program o.pdf
Two types of malware :-
1. Virus: A virus is a contagious program or code that attaches itself to another piece of software,
and then reproduces itself when that software is run. Most often this is spread by sharing
software or files between computers.
Virus cannot be spread without a human action. So when you share infected files or send email
with viruses as attachment in email, virus spread in another system also.
If you have turned off your anti-virus protection your system is vulnerable to virus and other
threats.
2. Trojan: This is the most dangerous Malware. Trojans are written with the purpose of
discovering your financial information, taking over your computer’s system resources, and in
larger systems creating a “denial-of-service attack ”.
Denial-of-service attack: an attempt to make a machine or network resource unavailable to those
attempting to reach it. Example: AOL, Yahoo or your business network becoming unavailable.
70% malware are trojan horse. When you open a file that have trojan horse or other kind of
unscrupulous virus program then it replicate in your system and your system is also get infected.

Ans.1A path, the general form of the name of a file or directory, .pdf
Ans.1
A path, the general form of the name of a file or directory, specifies a unique location in a
filesystem. A path points to a file system location by following the directory tree
hierarchyexpressed in a string of characters in which path components, separated by a
delimitingcharacter, represent each directory.
The delimiting character is most commonly the slash (\"/\"),the backslash character (\"\\\"), or
colon (\":\"), though some operating systems may use a differentdelimiter. Paths are used
extensively in computer science to represent the directory/filerelationships common in modern
operating systems, and are essential in the construction ofUniform Resource Locators
(URLs).Systems can use either absolute or relative paths.
A full path or absolute path is a path thatpoints to the same location on one file system regardless
of the working directory or combinedpaths. It is usually written in reference to a root directory.
Ans.2
An operating system provides four access rights for files and most other resources:
• Create a new instance of the resource (for example, a new file).
• Read the contents of a particular resource.
• Update or write ” or “modify” a particular resource.
• Delete or destroy an existing resource.
The names of these four rights form the acronym CRUD While the four rights also may apply to
RAM and processes, its more common for programs to apply them to files. When a process tries
to create or use a file, it inherits whatever rights belong to the user who started the process. Some
systems also provide a right to append to a file; that is, add data to the end of the file without
reading its contents. There also may be an execute right.
Ans. 8
Computer worms are similar to viruses in that they replicate functional copies of themselves and
can cause the same type of damage. In contrast to viruses, which require the spreading of an
infected host file, worms are standalone software and do not require a host program or human
help to propagate.A Trojan is another type of malware named after the wooden horse the Greeks
used to infiltrate Troy. It is a harmful piece of software that looks legitimate. Users are typically
tricked into loading and executing it on their systems. After it is activated, it can achieve any
number of attacks on the host, from irritating the user (popping up windows or changing
desktops) to damaging the host (deleting files, stealing data, or activating and spreading other
malware, such as viruses). Trojans are also known to create back doors to give malicious users
access to the system.
Unlike viruses and worms, Trojans do not reproduce by infecting other files nor do they self-
replicate. Trojans must spread through user interaction such as opening an e-mail attachment or
downloading and running a file from the Internet.

The decomposition of hydrogen peroxide to gaseous.pdf
The decomposition of hydrogen peroxide to gaseous O2 and water is a spontaneous
process only means H2O2 is thermodynamically unstable. The fact that H2O2 is stable for long
periods of time indicates that H2O2 is kinetically stable. Thus. Adding catalyst will speed the
decomposition reaction up cause it decreases the activation energy.

Im not entirely sure what this is asking. I ass.pdf
I\'m not entirely sure what this is asking. I assume these are two processes being
performed on the molecule shown. I\'ve seen similar reactions and not exactly the same thing.
OsO4 usually adds OH cis if I recall to the inner carbons, but the OH groups are already there.
The second part of that might add SO2? For question 2 I\'m almost certain that the initial reaction
removes the OH groups on the original molecule and makes it into an epoxide. adding hydroxide
and H20 would make it a basic environment so an H+ in solution would protonate the epoxide.
OH would attach wherever the bond to the protonated epoxide was weakest, resulting in the
initial molecule with one of the centers having inverted stereochemistry 40% sure on all of this at
best. I just had my orgo final. good luck on yours :)

First remember that non polar compounds are solub.pdf
First remember that non polar compounds are soluble in non polar solvents (like
benzene in acetone) and polar compounds are soluble in polar solvents (like NaCl in H2O) Now
if you consider solubility in water, all polar compounds are soluble and the structure which can
make hydrogen bonding with water is also soluble like methanol which can form hydrogen
bonding with water.. First look at the structure to identify what kind of bonds are existing, if you
see any ionic bond it will be soluble in water. inorganic base is something like NaOH which has
the basic unit OH- which can easily take a proton from an organic acid and from a bond and
hence it will be soluble. organic base is soluble when organic acid is present because acid and
base has the larger tendency to get interacted and form a complex.

Photosynthesis - is the unique process that is limited to plant king.pdf
Photosynthesis - is the unique process that is limited to plant kingdom.Green plants are able to
synthesize carbohydrates in there systems due to the presence of an uinique structure called
chloroplast.
The chloroplasts are present only in plant kingdom which gives them the ability to trap solar
energy convert it into chemical energy along with the synthesis of carbohydrates and evolution
of oxygen, so the process of photosynthesis does not only fix the carbon di oxide but in the
process also give out oxygen.
These chloroplasts are present in diverse groups of plant kingdom and may show structural
differences . Though they exhibit variations in their structure they perform the same function.The
chloroplasts are membrane bound organnels locate din the cytoplasm and are responsible for the
trapping of solar energy and converting it into chemical energy in the form of ATP and
NADPH due to the presence of the pigment chlorophyll and in the process liberate oxygen from
the water molecule through a series of reactions.
The number of chloroplasts per cell vary from one organism to the other they may be varying
from 1 as seen in algae or may be upto 100 per cell as seen in higher plants.the chloroplasts
develop from a pre existing plastids known as the proplastid.whcih can develop into a variety of
plastids like the chloroplast, leucoplast amyloplast etc.
They are considered to have originated from cyanobacteria through endosymbiosis .The
ancestors of chloroplasts are believed to be the cyanobacteria or the blue-green algae .They are
often found as symbionts with a number of other groups of organisms like the
fungi,pteridophytes angiosperms .The oxygen present in the atmosphere is attributed due to the
activity of these cyanobacteria.They do not have a nucleus or any membrane bound organnels .
The photosynthetic apparatus is embedded into folds of the external cell membrane, called
thylakoids and contain a bluish green pigment phycocyanin and chlorophyll a.
The green algae cor the chlorophytes have a definite chloroplast whose shape may vary among
different members it may be cup shaped as seen in simple chlamydomonas , ribbon like as in
spirogyra or disc like as in higher members of the group . The main pigments are chlorophyll a, b
along with carotenoids and xanthophylls and have starch as the storage product.
the members of red algae have additional pigments in there chloroplast like phycobilins and
phycocyanins in addition to chlorophyll and the starch they make is also called as floridean
starch unique to the group.The brown algae differ from the other groups due to the presence of
the pigment fucoxanthin along with chlorophyll a and c which gives them the color.
If we move to higher group of plants like the bryophytes , Pteriodophytes, Gymnosperms and the
Angiosperms the chloroplast represents a well organized double membrane structures with they
thylakoids, grana , stroma , intergaranal lamella , stromal lamella and have chlorophyll as the
main.

Organism Entameoeba histolyticQ AIt can be analyzed by feces te.pdf
Organism :Entameoeba histolytic
Q A
It can be analyzed by feces tests, however take note of that specific different species are difficult
to recognize by microscopy alone. Trophozoites might be found in a new fecal spread and sores
in a standard feces test. ELISA or RIA can likewise be utilized
Q B
The dynamic (trophozoite) arrange exists just in the host and in crisp free defecation; growths
make due outside the host in water, in soils, and on sustenances, particularly under wet
conditions on the last mentioned.
Q C
Distinctive monophasic media that were created for E. histolytica are the egg yolk imbuement
medium of Balamuth , Jones\' medium , and TYSGM-9 . Of the diverse media created for the
xenic development of E. histolytica, just three media, diphasic Locke-egg, Robinson\'s medium
Q D
anaerobic
QE
Microscopy utilized in an indicative clinical research facility incorporate wet planning, fixation,
and for all time recolored smears for the distinguishing proof of E. histolytica/E. dispar/E.
moshkovskii in excrement. Tiny examination of an immediate saline (wet) mount is an
exceptionally uncaring strategy (<10%) which is performed on a crisp example .The example
ought to be analyzed inside 1 h of accumulation to hunt down motile trophozoites which may
contain RBCs. Be that as it may, in patients who don\'t present with intense looseness of the
bowels, trophozoites won\'t contain RBCs. Patients with asymptomatic carriage by and large
have just growths in the fecal example. In spite of the fact that the focus procedure is useful in
exhibiting sores, the utilization of forever recolored smears (trichrome or press hematoxylin) is
an imperative technique for recuperation and distinguishing proof of Entamoeba species.
Q F Q G
In most by far of cases, disease is asymptomatic and the bearer is uninformed they are tainted.
Be that as it may, in an expected 10% of cases E. histolytica causes ailment. Once the
trophozoites are excysted they colonize the extensive gut, staying on the surface of the bodily
fluid layer and sustaining on microscopic organisms and sustenance particles. Every so often,
and in light of obscure boosts, trophozoites travel through the bodily fluid layer where they
interact with the epithelial cell layer and begin the obsessive procedure. E. histolytica has a lectin
that ties to galactose and N-acetylgalactosamine sugars on the surface of the epithelial cells, The
lectin typically is utilized to tie microscopic organisms for ingestion. The parasite has a few
catalysts, for example, pore shaping proteins, lipases, and cysteine proteases, which are regularly
used to process microbes in nourishment vacuoles yet which can bring about lysis of the
epithelial cells by instigating cell putrefaction and apoptosis when the trophozoite interacts with
them and ties through the lectin. The trophozoites will then ingest these dead cells. This harm to
the epithelial cell layer draws in human resistant cells and these thusly can be lysed by .

A Strategic Approach: GenAI in Education
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.
