Fen Bilimleri 2018 Çıkmış Sorular Çöz (Part 4) - Yökdil Cümle Tamamlama Soruları Çöz
Soru 1 |
Modern estimates suggest that 85 percent of the universe’s mass is invisible to even the most powerful telescopes -------.
following the deduction that several objects
have been used | |
where several decades of experiments have
proved ineffective | |
and is only detectable through the influence
of its gravity | |
so that it simply does not interact with light | |
but evidence about the fate of our galaxy is
limited |
Soru 2 |
Although we do not typically think of bacteria as being capable of sight, -------.
antibiotics can kill the good bacteria in the
body along with the bad | |
such detailed studies aim to pay special
attention to the species crisis | |
humans have been wondering about the
answer to these questions for centuries | |
they have light-responsive proteins that are
similar to our own visual system | |
they started to believe that perhaps the
signals were not random |
Soru 3 |
....................., mercury levels in the oceans have increased at an alarming rate since the Industrial Revolution.
Despite the amount of mercury in fish and
mammals | |
Due to mining and the burning of fossil fuels | |
In agreement with global efforts to protect
the ecosystem | |
As tuna is a kind of long-lived predator in the
oceans | |
Even after heavy fishing in the Pacific
Ocean |
Soru 4 |
‘Erosion’ is a blanket or general term for a variety of processes -------.
even though the carving of canyons by
rivers is an example of erosion | |
but they played a more important role on
Earth than on any other planet | |
therefore, much of the surface rock on Earth
was caused by erosion | |
that break down or transport rock through
the action of ice, liquid, or gas | |
if such substances are used to build new
communal structures |
Soru 5 |
The dominance of fossil fuels will remain unchallenged for at least the next four decades, ..............
therefore, green policies will play an
important role in our immediate energy
needs | |
even if countries pursue environmental or
energy policies enforced by international
agreements | |
thus, the amount of European power
supplied by renewables is more than that of
fossil fuels | |
now that renewable sources are urgently
needed for sustainable development | |
as well as a large number of countries
dependent on renewable energy sources |
Soru 6 |
Even the simplest life form on Earth has countless requirements needed to survive, -------
when the Earth was only 700 million years
old | |
as planets may have some sources of
energy | |
resulting in nature and intelligent life | |
it is determined by many environmental
factors | |
such as water, organic materials and energy |
Soru 7 |
When the brain cells of humans and all other mammals are starved of oxygen, -------.
such innovations in the field of science have
become compulsory | |
such levels depend on age and gender of
the species
| |
biology deals with humans, animals as well
as plants | |
they run out of sufficient energy and begin to
die as a result | |
oxygen level in brain cells plays a vital part
in humans |
Soru 8 |
Scientists have finally established the identity of a missing element within the Earth's core, -------.
for which they have been searching for
many decades | |
that strongly argues that the earth orbits the
sun | |
but the core first separated from the rocky
parts of Earth | |
whose work was needed to confirm the
presence of silicon | |
who could help us to better understand how
they formed |
Soru 9 |
Producing artificial spider silk has long been a dream of many scientists, -------
as long as spiders spin small amounts of silk
in labs | |
though such products require plenty of silk
for large scale production | |
but it is still too early for them to expect the
dream to come true | |
whereas it is well tolerated when it is
implanted in tissues | |
because the researchers have a method
that works properly
|
Soru 10 |
While flowing water has not been directly observed on Mars, -------.
there are signs that it has potentially made
some brief appearances on the surface | |
the scientists who travelled to this continent
concluded that it has large reservoirs of
water | |
the initial report from Mariner 4 stated that
these planets never had Earth-like oceans | |
water is not found on the surface or within
rocks and soil in any of its forms
| |
continued monitoring shows that such
activity may be due to chemical processes |
