P1.
• X is a glycoprotein found in the saliva of
vampire bats. It is composed of 411 amino
acids. It functions as an anticoagulant,
inhibiting coagulation factors IX (IXa) and X
(Xa), thus keeping the blood of the bitten
victim from clotting while the bat is drinking.

P2.
• Quote by a certain dead Navy fighter pilot-
"I am, and ever will be, a white socks, pocket
protector, nerdy engineer," he said in February
2000 in one of his rare public appearances.
"And I take a substantial amount of pride in
the accomplishments of my profession”.
Name this pilot whose accomplishments
transcended all geographical boundaries.

P3.
• The following minerals are detectable in
_________ by X-ray diffraction:
brushite, octacalcium phosphate, magnesium-
containing whitlockite, and carbonate-
containing hydroxyapatite

P4. What is being described ??
• The spatulae tipped setae facilitate attractive
forces called van der Waals forces to arise
between the setae structures and the surface.
• These van der Waals interactions involve no
fluids. The setae are also self-cleaning and will
usually remove any clogging dirt . Recent
studies have also revealed that apart from the
setae, secreted phospholipids also come into
play. These lipids lubricate the setae.

P5. What has been blocked out ?

P6. Identify this very famous
astronomer.
• In 1994, engineers at Apple Computer code-named the
Power Macintosh 7100 X in the hope that Apple would
make "billions and billions" with the sale of the
PowerMac 7100. The name was only used internally, but X
was concerned that it would become a product
endorsement and sent Apple a cease-and-desist letter.
Apple complied, but engineers retaliated by changing the
internal codename to "BHA" for "Butt-Head Astronomer". X
then sued Apple for libel, a form of defamation, in federal
court. The court granted Apple's motion to dismiss X's
claims and opined in dicta that a reader aware of the
context would understand Apple was "clearly attempting to
retaliate in a humorous and satirical way"

P7.
• X literally means “that which resembles a
cloud”. X is supposed to have originated from
the bones of Maharishi Dadhichi. Acoording to
mythology Maharishi Dadhichi made the
weapon Vajrayudha(thunderbolt) with his
bones and presented it to Indra to kill
Vritrasura.Vajrayudha while finding its
triumphant way through the sky, produced
sparkles which became X

P8.
• X is an anglerfish of
the family Brachionichthyidae.
• X are small fish, growing up to 15 centimetres
(5.9 in) long, have skin covered
with denticles (tooth-like scales), giving them the
alternate name warty anglers. They are slow-
moving fishes that prefer to 'walk' rather than
swim, using their modified pectoral fins to move
about on the sea floor.

P9.
The definition of planet set in 2006 by
the International Astronomical Union (IAU) states
that, in the Solar System, a planet is a celestial
body which:
(a) is in orbit around the Sun,
(b) has sufficient mass for its self-gravity to
overcome rigid body forces so that it assumes a
hydrostatic equilibrium (nearly round) shape, and
(c) _________________

P11. FITB
• The French mathematician _____ invented the
eponymous _____ ____ in its modern form in
1631. Its use was described in detail in English
in Navigatio Britannica (1750) by John Barrow,
the mathematician and historian. In some
languages, this device is called a nonius. It was
also commonly called a nonius in English until the
end of the 18th century. Nonius is the Latin name
of the Portuguese astronomer and
mathematician Pedro Nunes who in 1542
invented a related but different system.

P12.
• A ________ radio receiver, also called a _____
set is a very simple radio receiver, popular in
the early days of radio. It needs no battery or
power source and runs on the power received
from radio waves by a long wire antenna. It
gets its name from its most important
component, known as a _______
detector, originally made with a piece of
_________ mineral such as galena. This
component is now called a diode.

Synthia or Mycoplasma Laboratorium. What
special about this organism?

Where in automobiles will you come across the
following reactions?

Biologist, shown here in a

in Bengali science fiction. He supposedly was
the first science fiction writer in the Bengali
language.

P19. Who is the author of this
manuscript ?

*P22.
• In addition to working as a scientist, X painted. He was a
member of the Chelsea Arts Club, where he created
amateurish watercolors. Less well known is that he also
painted in another medium, living organisms. X painted
ballerinas, houses, soldiers, mothers feeding children, stick
figures fighting and other scenes using bacteria. He
produced these paintings by growing microbes with
different natural pigments in the places where he wanted
different colors. He would fill a petri dish with agar and
then use a wire lab tool called a loop to inoculate sections
of the plate with different species. The paintings were
technically very difficult to make. X had to find microbes
with different pigments and then time his inoculations such
that the different species all matured at the same time.

*P23. What is this kind of cloud formation called ?
It is associated with extreme weather..

*P24. This Indian Science Fiction novel
(subtitled “A novel of Fevers, Delirium
and Discovery”) describes a
transmigration – not of souls, but
of one person’s disposition and
temperament, bit by bit, to another
person – through a physical entity.

*P25.
X is the sum of the first 36 natural numbers , and thus it is
a triangular number.
X is also an abundant number and a palindrome.
The harmonic mean of the decimal digits of X is 6.

occurrence of all symbols whose value is less than 1000

*P29.
• In paleontology, a X taxon is a taxon that
disappears from one or more periods of the fossil
record, only to appear again later. X taxa are
observational artifacts that appear to occur
either because of (local) extinction, later
resupplied, or as a sampling artifact. If the
extinction is conclusively found to be total (global
or worldwide) and the supplanting species is not
a lookalike (an Elvis species), the observational
artifact is overcome.

• X are mostly made of a polymer called Lignin
which in turn is made up of repeating units of
Vanillin.

be one of the reasons behind this
“phenomenon”.
• Which “phenomenon” ?

*P31.
• Blaise Pascal introduced a primitive form of X machine
in the 17th century in his search for a perpetual motion
machine.
• A X is a kind of curve,
generalizing cycloids, epicycloids, hypocycloids, trochoi
ds, and involutes. Given a curve attached to a plane
which is moving so that the curve rolls without slipping
along a given curve attached to a fixed plane occupying
the same space, then a point attached to the moving
plane describes a curve in the fixed plane called a X.

P33. What’s X?
• The “X” Snake (now Zamenis longissimus, previously Elaphe
longissima), is a nonvenomous snake native to Europe. The
species has been of cultural and historical significance for its

symbolism.
• The common name “X” of the species refers to the
____________ whose temples the snake was encouraged
