Context and question: Africa separated from Antarctica in the Jurassic, around 160 Ma, followed by the Indian subcontinent in the early Cretaceous (about 125 Ma). By the end of the Cretaceous, about 66 Ma, Antarctica (then connected to Australia) still had a subtropical climate and flora, complete with a marsupial fauna. In the Eocene epoch, about 40 Ma Australia-New Guinea separated from Antarctica, so that latitudinal currents could isolate Antarctica from Australia, and the first ice began to appear. During the EoceneOligocene extinction event about 34 million years ago, CO2 levels have been found to be about 760 ppm and had been decreasing from earlier levels in the thousands of ppm.
What currents began isolating Australia in 66 Ma
Answer: unanswerable
Context and question: Whereas the chromosomes of prokaryotes are relatively gene-dense, those of eukaryotes often contain regions of DNA that serve no obvious function. Simple single-celled eukaryotes have relatively small amounts of such DNA, whereas the genomes of complex multicellular organisms, including humans, contain an absolute majority of DNA without an identified function. This DNA has often been referred to as "junk DNA". However, more recent analyses suggest that, although protein-coding DNA makes up barely 2% of the human genome, about 80% of the bases in the genome may be expressed, so the term "junk DNA" may be a misnomer.
What type of organism has relatively gene dense chromosomes?
Answer: prokaryotes
Context and question: The Science Fiction Hall of Fame inducted Spielberg in 2005, the first year it considered non-literary contributors. In November 2007, he was chosen for a Lifetime Achievement Award to be presented at the sixth annual Visual Effects Society Awards in February 2009. He was set to be honored with the Cecil B. DeMille Award at the January 2008 Golden Globes; however, the new, watered-down format of the ceremony resulting from conflicts in the 200708 writers strike, the HFPA postponed his honor to the 2009 ceremony. In 2008, Spielberg was awarded the Legion d'honneur.
In what year was the first Cecil B. DeMille award handed out?
