Neon is a member of the noble gas family. Other elements in this family includes <span>helium, argon, krypton, xenon, </span>and <span>radon. </span>These gases are in Group 18 (VIIIA) of the periodic table. The periodic table is a chart that shows how chemical elements are related to each other. The noble gases are sometimes called the inert gases. This name comes from the fact that these elements do not react very readily. In fact, compounds exist for only three noble gases—krypton, radon, and xenon. Chemists have yet to prepare compounds of helium, neon, or argon.
Neon was discovered in 1898 by British chemists William Ramsay (1852-1916) and Morris Travers (1872-1961). It occurs naturally in the atmosphere, but only in very small amounts.

The only disorder that cannot be represented using pedigree chart is sickle cell anemia. this because hemophilia, red-green color blindness, and duchenne muscular dystrophy are all X-linked traits. on the other hand sickle cell anemia is an autosomal recessive condition which cannot be represented in the pedigree chart since only sex linked traits are found this chart.
D is the answer. Since it’s caused by a subduction.
