[Q]: The Juscelino Kubitschek bridge, also known as the 'President JK Bridge' or the 'JK Bridge', crosses Lake Paranoá in Brasília. It is named after Juscelino Kubitschek de Oliveira, former president of Brazil. It was designed by architect Alexandre Chan and structural engineer Mário Vila Verde. Chan won the Gustav Lindenthal Medal for this project at the 2003 International Bridge Conference in Pittsburgh due to "...outstanding achievement demonstrating harmony with the environment, aesthetic merit and successful community participation".

[Q]: Gene nomenclature has been established by the HUGO Gene Nomenclature Committee (HGNC) for each known human gene in the form of an approved gene name and symbol (short-form abbreviation), which can be accessed through a database maintained by HGNC. Symbols are chosen to be unique, and each gene has only one symbol (although approved symbols sometimes change). Symbols are preferably kept consistent with other members of a gene family and with homologs in other species, particularly the mouse due to its role as a common model organism.
[A]: What committee has established gene nomenclature for every known human gene?


[Q]: Development of the fertilized eggs is direct, in other words there is no distinctive larval form, and juveniles of all groups generally resemble miniature cydippid adults. In the genus Beroe the juveniles, like the adults, lack tentacles and tentacle sheaths. In most species the juveniles gradually develop the body forms of their parents. In some groups, such as the flat, bottom-dwelling platyctenids, the juveniles behave more like true larvae, as they live among the plankton and thus occupy a different ecological niche from their parents and attain the adult form by a more radical metamorphosis, after dropping to the sea-floor.
[A]:
Juvenile and adult  beroe lack what?
