Middle latitudes Middle latitudes The middle latitudes (also called the mid-latitudes, sometimes midlatitudes, or moderate latitudes) of Earth lie between 23°26'22" and 66°33'39" north, and between 23°26'22" and 66°33'39" south. They include Earth's subtropical and temperate zones, which lie between the tropics and the polar circles (between the Tropic of Cancer and the Arctic Circle, and between the Tropic of Capricorn and the Antarctic Circle). Weather fronts and extratropical cyclones are usually found in this area, as well as occasional tropical cyclones, which have traveled from their areas of formation closer to the Equator. The prevailing winds in the middle latitudes are
The Hallmarks of Cancer be able to avoid interaction with the body’s via a loss of interleukin-33 immune system. (See cancer immunology) The updated paper also identified two emerging characteristics. These are labeled as such since their acquisition leads to the development of the hypothesized "hallmarks" Cancer cells generally have severe chromosomal abnormalities which worsen as the disease progresses. HeLa cells, for example, are extremely prolific and have tetraploidy 12, trisomy 6, 8, and 17, and a modal chromosome number of 82 (rather than the normal diploid number of 46). Small genetic mutations are most likely what begin tumorigenesis, but once cells begin the
