Greece, together with Italy and Spain, is a major entry point for illegal immigrants trying to enter the EU. Illegal immigrants entering Greece mostly do so from the border with Turkey at the Evros River and the islands of the eastern Aegean across from Turkey (mainly Lesbos, Chios, Kos, and Samos). In 2012, the majority of illegal immigrants entering Greece came from Afghanistan, followed by Pakistanis and Bangladeshis. In 2015, arrivals of refugees by sea have increased dramatically mainly due to the ongoing Syrian civil war. There were 856,723 arrivals by sea in Greece, an almost fivefold increase to the same period of 2014, of which the Syrians represent almost 45%. An estimated 8% of the arrivals applied for asylum in Greece.
What percentage of sea immigrants asked for asylum in Greece?
8%

In nature, the red color of blood comes from hemoglobin, the iron-containing protein found in the red blood cells of all vertebrates. The red color of the Grand Canyon and other geological features is caused by hematite or red ochre, both forms of iron oxide. It also causes the red color of the planet Mars. The red sky at sunset and sunrise is caused by an optical effect known as Rayleigh scattering, which, when the sun is low or below the horizon, increases the red-wavelength light that reaches the eye. The color of autumn leaves is caused by pigments called anthocyanins, which are produced towards the end of summer, when the green chlorophyll is no longer produced. One to two percent of the human population has red hair; the color is produced by high levels of the reddish pigment pheomelanin (which also accounts for the red color of the lips) and relatively low levels of the dark pigment eumelanin.
What pigment is responsible for the color of leaves in fall?
anthocyanins
