Problem: It had been found that the proportion of non-repetitive DNA can vary a lot between species. Some E. coli as prokaryotes only have non-repetitive DNA, lower eukaryotes such as C. elegans and fruit fly, still possess more non-repetitive DNA than repetitive DNA. Higher eukaryotes tend to have more repetitive DNA than non-repetitive ones. In some plants and amphibians, the proportion of non-repetitive DNA is no more than 20%, becoming a minority component.
What do some plants and amphibians only have?

Problem: 58.1% of the population described themselves in the 2011 census return as being at least nominally Christian and 0.8% as Muslim with all other religions represented by less than 0.5% each. The portion of people without a religion is 32.9%; above the national average of 24.7%. 7.1% did not state their religious belief. Since the 2001 Census, the number of Christians and Jews has decreased (-16% and -7% respectively), while all other religions have increased and non-religious people have almost doubled in number.
What was the percentage decline in Jewish residents of Plymouth between 2001 and 2011?

Answer: 7%

Problem: The new SuperSpeed bus provides a fourth transfer mode with a data signaling rate of 5.0 Gbit/s, in addition to the modes supported by earlier versions. The payload throughput is 4 Gbit/s[citation needed] (due to the overhead incurred by 8b/10b encoding), and the specification considers it reasonable to achieve around 3.2 Gbit/s (0.4 GB/s or 400 MB/s), which should increase with future hardware advances. Communication is full-duplex in SuperSpeed transfer mode; in the modes supported previously, by 1.x and 2.0, communication is half-duplex, with direction controlled by the host.
How fast is the new SuperSpeed bus data signaling rate?

5.0 Gbit/s
