Pisgah Crater -- Pisgah Crater, or Pisgah Volcano, is a young volcanic cinder cone rising above a lava plain in the Mojave Desert, between Barstow and Needles, California in San Bernardino County, California. The volcanic peak is around 2.5 miles (4.0 km) south of historic U.S. Route 66-National Old Trails Highway and of Interstate 40, and west of the town of Ludlow. The volcano had a historic elevation of 2,638 feet (804 m), but has been reduced to 2,545 feet (776 m) due to mining.

question:
Monoamniotic twins -- Monoamniotic twins are identical twins that share the same amniotic sac within their mother's uterus. Monoamniotic twins are always identical, always monochorionic and are usually termed Monoamniotic-Monochorionic (``MoMo'' or ``Mono Mono'') twins. They also share the placenta, but have two separate umbilical cords. Monoamniotic twins develop when an embryo does not split until after formation of the amniotic sac, at about 9-13 days after fertilization. Monoamniotic triplets or other monoamniotic multiples are possible, but extremely rare. Other obscure possibilities include multiples sets where monoamniotic twins are part of a larger gestation such as triplets, quadruplets, or more.
answer:
do identical twins have to be in the same sac


question:
Appendicular skeleton -- The appendicular skeleton is the portion of the skeleton of vertebrates consisting of the bones that support the appendages. Appendages appeared as fins in early fish, and subsequently evolved into the limbs of tetrapods. The appendicular skeleton includes the skeletal elements within the limbs, as well as supporting pectoral and pelvic girdles in the case of tetrapods (these are lacking in fish). The word appendicular is the adjective of the noun appendage, which itself means a part that is joined to something larger.
answer:

pelvic girdle is part of the appendicular skeleton
