Answer:
Northern European citizens are among the healthiest in the world.
Explanation:
Northern Europe is a region that can be admired from pretty much every aspect. The countries located in this region tend to wealthy, well organized, people have high earnings, education is among the best in the world, etc. These countries actually managed to become as they are now in the past half a century, while before that they were relatively poor.
One thing that lot of people admire about these countries is their medical system. It is a socialist type of medical system, where every citizen is provided with free or very cheap healthcare. Not just that, but the medical personal is excellent and the patients are treated with the newest methods and technologies. When added to this the aforementioned positives, but also healthy living habits and clean environment, it is no wonder that the people of Northern Europe have among the highest life expectancies in the world.
The tropics would expand.
Explanation:
With the global temperatures rising the Earth is projected to have multiple changes, climatic ones and even in the shape of the landmasses. Because of the rising global temperatures the ice at the poles is expected to melt, if not all than in solid amount, which in turn will rise the sea level.
Higher sea level will mean that there will be less land mass, but also that the land mass will be under bigger maritime influence when it comes to the climate. The ocean currents also are expected to gradually become dominated by warm ocean currents, while the cold ones will be much less and with much lesser global influence. That will cause expansion of the tropics, mostly toward north, as toward south there is little land mass, and such expansion will totally change the landscape, the habitats, the diversity and type of species present in certain areas.
That would be 75% of Earth's atmosphere.
Answer:
Regardless of its name, the Big Bang theory found widespread acceptance for its unparalleled ability to explain what we see. The balance of light with particles like protons and neutrons during the first 3 minutes, for instance, let early elements form at a rate predicting the current amounts of helium and other light atoms.
"There was a small window in time where it was possible for nuclei to form," said Glennys Farrar, a cosmologist at New York University. "After that, the universe kept expanding and they couldn't find each other, and before [the window] it was too hot."
A cloudy plasma filled the universe for the next 378,000 years, until further cooling let electrons and protons form neutral hydrogen atoms, and the fog cleared. The light emitted during this process, which has since stretched into microwaves, is the earliest known object researchers can study directly. Known as the cosmic microwave background (CMB) radiation, many researchers consider it the strongest evidence for the Big Bang.
