(I) Such an assumption has not yet been tested rigorously for most animal species. (II) Vertebrates are often marked to facilitate the identification of free-ranging individual animals or groups for studies of behaviour, population biology, and physiology. (III) Marked animals provide data for home range use, resource selection, social behaviour, and population estimation. (IV) Markers can be classified into three general categories: mutilations, tags and bands, and radio transmitters. (V) The appropriate marking technique for a study depends on several considerations, including study objectives, target species, marker cost, marker efficacy, and marker effects on the animals.

There are many ways to define ‘time’ at a particular location. Here, on Earth, our usual system is defined by the motion of the Sun in the sky. This means that the local time depends on where you are on Earth and we get around this complication by having many different time zones. Now, we could also define a similar time system based on the motion of the Sun as seen from the Moon. Such a system exists but it is not much more than an interesting exercise in physics. -------. This is called Universal Time, and it is a modern form of Greenwich Mean Time. It is the same everywhere in the Universe.
There have been several unsuccessful
attempts to define a brand-new computing
system | |
Therefore, it will never be possible to
calculate exactly what time it is on the Moon | |
So, the time on the Moon can never be the
same as the time on Earth | |
It is difficult to keep track of time at work due
to the workload | |
What is more useful, however, is a definition
of time that does not vary with location |

Dünyanın başka hiçbir yerinde bulunmayan sayısız türün evi olarak bilinen tropik yağmur ormanları, daha önce hiç görülmemiş bir hızda yok ediliyor.
Tropical rainforests are the home to
numerous species found nowhere else in
the world, but they are being destroyed
rapidly.
| |
As tropical rainforests are being destroyed
at an alarming rate, numerous species found
nowhere else in the world are becoming
extinct at an unprecedented rate | |
Tropical rainforests, which are the home of
numerous species existing nowhere else in
the world, are being saved at an
unprecedented rate. | |
Known to be the home of numerous species
found nowhere else in the world, tropical
rainforests are destroyed at an
unprecedented rate. | |
Although it is known to be the home of
numerous species rarely found in the world,
tropical rainforests are destroyed at an
alarming rate. |

Late in the twentieth century, evidence of global warming mounted as ice sheets in the Arctic and Antarctic began melting rapidly. Carbon dioxide levels climbed, and the protective ozone layer shrank. Although Earth had experienced cycles of abnormal warmth and cold even before humans appeared, most scientists and some political leaders feared that human activity was seriously disrupting the world’s climate. They urged energy conservation and alternatives to carbon-rich oil and coal, such as solar and wind power, hydrogen, and synthetic fuels. -------
When the cold war was over, many nations
started scientific space exploration to
discover habitable planet | |
Like many developed countries, the United
States, proportionally the world’s largest
energy user, supports cost-efficient projects | |
As a result, 140 nations approved an
environmental agreement in 2005, known as
the Kyoto Protocols, in order to limit
destructive emissions | |
It has been long known that electric utilities
using fossil fuels produce greater air
pollution than nuclear power plants | |
However, one of the major challenges facing
developing countries today is to find
sufficient oil resources |

As honeybees develop, they undergo metamorphosis. -------. At the right moment, the protective wax caps put in place by worker bees are removed, revealing the pupae just days before they are ready to emerge as fully grown adults. Bees in this stage are pale, as their outer shells are not yet hardened. When they emerge as adults, their shells can still take a few hours to fully harden. This means that very young bees are more or less unable to sting
The queen bee is not involved in the
process of wax cell production | |
The shell of a new born bee is not as hard
as it is supposed to be | |
It is a great idea to mark honeybees if you
want to follow them | |
Young bees, compared to fully grown adults,
are less dangerous to us | |
Their lifecycle consists of four stages: egg,
larva, pupa, and adult |
Soru 6 |
There are objects that are classified neither as stars nor as planets, called ‘brown dwarfs’. -------. Brown dwarfs accumulate matter in the same way as stars, but fail to attain enough mass to ignite hydrogen fusion. Stars can fuse hydrogen into helium, which can only occur above a certain temperature and pressure. Thus, objects above this threshold are stars. Brown dwarfs initially produce heat by fusing an isotope of hydrogen called deuterium into helium-3, which occurs at lower temperatures and lower masses.
This term was first coined by Jill Tarter of
the SETI Institute | |
Such information will also explain the
processes that shaped the young Milky Way | |
NASA is looking for more information about
the planets’ atmosphere | |
Thus, more precise measurements will no
longer be needed | |
Researchers originally thought that the
system had three planets |
Soru 7 |
High-altitude landscapes are some of the most inhospitable places on Earth. They are cold, dry, and oxygen-poor, which causes sleeplessness, fatigue, coughing, confusion, and a rapid pulse. They were the last places humans settled, yet people did it and survived. -------. From the Himalayas to the Andes to the Ethiopian Plateau, people have evolved in ways that allow them to live at high altitude.
The Himalayas and the Andes attract many
climbers looking for adventure | |
Living at such heights causes hypoxia, a
condition where tissues cannot get enough
oxygen | |
This was all about our failure to cope with
such an extreme phenomenon | |
It is easier to find well-protected remains of
ancient empires than ever before due to
technology | |
The only logical explanation for this is our
ability to adapt, especially to extreme
environments |
Soru 8 |
Bilim insanları, yetersiz petrol ve gaz kaynaklarına sahip olan ülkelerin, yenilenebilir enerjiye geçmesini öneriyor.
Since the country has limited oil and gas
resources, scientists propose to use more
renewable energy.
| |
Scientists recommend that countries with
insufficient oil and gas resources should
shift to renewable energy | |
Considering how little oil and gas resources
countries have, scientists recommend a shift
to renewable energy. | |
The restricted oil and gas resources in the
country forced scientists to propose a rapid
shift to renewable energy | |
Due to limited oil and gas resources in the
country, scientists strongly recommend a
shift to renewable energy. |

Ceres, an unassuming-looking object made of ice and rock, lies between Mars and Jupiter in the expanse of the Asteroid Belt. It was first spotted by Sicilian astronomer Giuseppe Piazzi on 1 January 1801. This 965-kilometre diameter ball could just have been considered a dead, grey rock in space. -------. It has been discovered that it was – and possibly still is – an active world that may have had cryovolcanoes of the kind that has pretty much disappeared from Earth.
Just one solitary peak made of ice, mud and
salts, called Ahuna Mons | |
That is, if it erupts icy materials like water
ice, or methane instead of lava | |
There are also some other mountains on
Ceres such as Liberalia and Yamor | |
These planets are not the only bodies
discovered in our Solar system | |
But as NASA’s Dawn spacecraft has
recently uncovered, Ceres has been hiding
a strange secret

Soru 10 |
Bazı tasarımcılar için üretim sürecinde yapıtları üzerinde belli bir ölçüde denetime sahip olmaları önemlidir
Retaining a degree of control over their work
in the production stage is considered vital by
designers | |
It is important for some designers to retain a
degree of control over their work in the
production process | |
Some designers believe that retaining
control over their work in the production
process is vital. | |
For designers who produce certain works, it
is necessary to retain a degree of control
over their work. | |
According to designers, retaining some
degree of control over the production
process is really important |
