The TD Garden, formerly called the FleetCenter and built to replace the old, since-demolished Boston Garden, is adjoined to North Station and is the home of two major league teams: the Boston Bruins of the National Hockey League and the Boston Celtics of the National Basketball Association. The arena seats 18,624 for basketball games and 17,565 for ice hockey games. The Bruins were the first American member of the National Hockey League and an Original Six franchise. The Boston Celtics were founding members of the Basketball Association of America, one of the two leagues that merged to form the NBA. The Celtics have the distinction of having won more championships than any other NBA team, with seventeen.

How many people can be seated for an ice hockey game at TD Garden?
Answer: 17,565

Brasilia has a tropical savanna climate (Aw) according to the Koppen system, with two distinct seasons: the rainy season, from October to April, and a dry season, from May to September. The average temperature is 20.6 C (69.1 F). September, at the end of the dry season, has the highest average maximum temperature, 28.3 C (82.9 F), has major and minor lower maximum average temperature, of 25.1 C (77.2 F) and 12.9 C (55.2 F), respectively. Average temperatures from September through March are a consistent 22 C (72 F). With 247.4 mm (9.7 in), January is the month with the highest rainfall of the year, while June is the lowest, with only 8.7 mm (0.3 in).

When is Brasilia's rainy season?
Answer: October to April

20th century developments in plant biochemistry have been driven by modern techniques of organic chemical analysis, such as spectroscopy, chromatography and electrophoresis. With the rise of the related molecular-scale biological approaches of molecular biology, genomics, proteomics and metabolomics, the relationship between the plant genome and most aspects of the biochemistry, physiology, morphology and behaviour of plants can be subjected to detailed experimental analysis. The concept originally stated by Gottlieb Haberlandt in 1902 that all plant cells are totipotent and can be grown in vitro ultimately enabled the use of genetic engineering experimentally to knock out a gene or genes responsible for a specific trait, or to add genes such as GFP that report when a gene of interest is being expressed. These technologies enable the biotechnological use of whole plants or plant cell cultures grown in bioreactors to synthesise pesticides, antibiotics or other pharmaceuticals, as well as the practical application of genetically modified crops designed for traits such as improved yield.

What opened the door to plant genetic engineering?
Answer:
all plant cells are totipotent
