In people with chronic myelogenous leukemia, the chromosomes in the blood cells swap sections with each other. A section of chromosome 9 switches places with a section of chromosome 22, creating an extra-short chromosome 22 and an extra-long chromosome 9.
Discovered on September 23, 1846, by John Couch Adams. Neptune was the first planet found by mathematical prediction rather than by observation. Unexpected changes in the orbit of Uranus led astronomers to deduce that its orbit was subject to gravitational perturbation by an unknown planet.
Neptune. Neptune is the 8th planet in our Solar System and the furthest from the Sun, being some 2,798,310,157 miles from the Sun. This was the first planet to be found using mathematics rather than observation techniques. Neptune is the fourth-largest planet by diameter and the third-largest by mass.Neptune as with Uranus is an Gas Giant and also an Ice Giant, and has 12 known moons orbiting it, and the planet orbits the Sun every 165 Earth years and has been named after the Roman god of the sea.eptune is the fourth-largest planet by diameter and the third-largest by mass.
