Often described
as
a
'smile

a
carcumzenithal
arc
occurs when
the
sun
shines
at a
right
angle
through
high clouds
(approximately
6100
-
7600 metres
high) made
of
ice crystals
about
the
size
of
salt
grains,
which refract
the light into
a brilliant
spectrum
of
colour.
The
arc
is
only
visible when
the sky is
free
of
low-level
clouds
and
when
the
sun
sits
less
than about 33
degrees above

ln 1609,
Galileo Galilei
made
an
improved telescope.
Unfortunately,
the
final
image
through Galileo's
telescope
was upside-down.
Modern
telescopes
for
use
on
Earth
have
a different
lens
system
so
that the
final
image
is the
right way
up.
A similar
system is used
for
binoculars.
However,
using
this
lens
system
blurs
the

Astronomers

Many
metals can be beaten
into
shape.
We say
they are
malleable.
Gold
is
the
most
malleable
metal as
it
can be
beaten
into very thin

leaf.
Gold
is also the
most ductile
metal, as
it
can
be
pulled
into
very
fine wire
without
breaking.
Gold
was
once
used
to make
coins,
but
its
main use
today
is
in
jewellery.
Since
gold
is so
prized,
it is called
a
precious
metal. Silver
is another beautiful
precious
metal
that
has been
used
for
jewellery
since
ancient
times.
However,
its main
use
today
is

The

surgery,
but
indirect inguinal
hernias

Questions

are
based
on the
following
text.
Avian
influenza
appears
to
spread
from
birds
to humans
through direct,
close contact
with sick birds
or with fecal-contaminated
surfaces.
As
yet,
there
is no confirmed
evidence
that avian
influenza
spreads
from
person
to
person.
Influenza
viruses,
however, mutate
easily.
Scientists
and
public
health
experts
fear that
an
avian
flu
strain
might
strike
a
person
who is already
infected
with
a
human
variant
of influenza.
The
two
variants
could
swap, or combine,
their
viral components in the infected
person
before
spreading
to other
people.
This combination
of virus
components
could
even
take
place
in
a susceptible
mammal.
The
result
could
be
a novel
virus
strain
completely unknown
to
the human
immune
system. It
could be especially
virulent
and
cause
death
in
a
high
percentage
of
infected individuals, passing
easily
from
person
to
person.
Such
a virus
could touch
off

of
people.

A
young
boy's
ear has
been bitten off by
a
dog.
Re-attachment
of the ear
is
viable,
but
an
adequate
blood supply
is
vital to
its
survival. The
surgeons
re-attach
the ear using microsurgical
techniques. However,
the
blood supply is
still
compromised, and
the
tissues
could
perish.
A leech is
applied to the
ear
to feed
on the blood
and
maintain
circulation, keeping the
tissues
alive.
This allows time for
the
ear's

It takes
more
than
an
ordinary
sponge to
take on
a slimy
biofilm.
US
researchers
have
found one
up
to the challenge.
Biofilms
can
kill almost
anything,
so
when they
discovered
a sponge
thriving
in an
otherwise
lifeless section
of ocean,
they
were
amazed.
They noticed
the sponge
growing
unaffected
in a bed
of dead
coral that
was completely
biofouled.
This
led
them to believe
that
the
sponge
produced
compounds
to
fight
off
biofouling,
biofilms
and
bacterial
infections.
When analyzing
the sponge
in the
lab,
the
team
detected
a chemical
that
was
able
to
reprogramme
bacteria
normally unaffected
by
antibiotics
and
make
them

is
the

factor

They
are
less tolerant
to
environmental
change.
B

are unaffected
by
environmental
stresses.

The
increased
exposure
to
air
increases
the
amount
of
oxygen
available
for
combustion.
For
example,
people
often
use
small
twigs
and
pieces
of
wood
called
kindling
to
start
a
campfire. Kindling
has
a large
amount
of
surface
area
compared
to
its
volume
which
means
that
kindling
heats
and
ignites
more
easily
than
thicker
pieces
of
wood.
Once
ignited,
kindling
burns
quicklY.

Amphibians
tend
to
have
smaller
ranges
and
less
tolerant
of environment
change
than
birds
and
mammals,
making
them
more
vulnerable
to
habitat
loss
and
over-hunting.
Yet
neither
factor
is
responsible
for
their
drastic
population
decline.
Scientists
blame
these
enigmatic
declines
on
the
fungal
disease
chytridiomycosis,
yet
the
fungus
was
present
well
over
a
decade
before
the
sudden
declines
began.
Scientists
suspect
that
environmental
stresses
are
making
amphibians
more
susceptible
to the
fungus.

oppropriate
answer
from
the
options given.
Typhonium flagelliforme,
or
Keladi
Tikus,
which
is
a
form
of
yam,
can be
easily found
in
the Malaysian
forest.
lt
has
been
used
for 26
internal
injuries
and
edema.
The
rhizomes of the
plant
have
traditionally been used
as
expectorant
for
coughs
and
as
treatment
for
pulmonary
27 . ln
the
Philippines,
the
floral
inflorescence
is
used
to 28
bleeding
and
help
in
wound
healing.
The
plant
was
found
to
possess
anti-cancer
29 in early 1990s
but
until
today
it
has not
been
used officially
as
anti-cancer
remedy
because
the
active compounds
have not
been
discovered.
However,
this
plant
has been
used extensively
as one
of the
components
of traditional herb for
30
breast, lung, colon
and liver
cancer. ltokawa and Takeya
(1993)
discovered
that extracts of the
fresh roots, rhizomes, stems
and leaves of flagelliforme
had
cytotoxic activity
against
P388
cells.
