question:
Southampton was named "fittest city in the UK" in 2006 by Men's Fitness magazine. The results were based on the incidence of heart disease, the amount of junk food and alcohol consumed, and the level of gym membership. In 2007, it had slipped one place behind London, but was still ranked first when it came to the parks and green spaces available for exercise and the amount of television watched by Sotonians was the lowest in the country. Speedway racing took place at Banister Court Stadium in the pre-war era. It returned in the 1940s after WW2 and the Saints operated until the stadium closed down at the end of 1963. A training track operated in the 1950s in the Hamble area.

What magazine awarded Southampton "fittest city in the UK" in 2006?


question:
Sumerian cities during the Uruk period were probably theocratic and were most likely headed by a priest-king (ensi), assisted by a council of elders, including both men and women. It is quite possible that the later Sumerian pantheon was modeled upon this political structure. There was little evidence of organized warfare or professional soldiers during the Uruk period, and towns were generally unwalled. During this period Uruk became the most urbanized city in the world, surpassing for the first time 50,000 inhabitants.
answer:
What is an "ensi"?


question:
Genes are regulated so that they are expressed only when the product is needed, since expression draws on limited resources.:7 A cell regulates its gene expression depending on its external environment (e.g. available nutrients, temperature and other stresses), its internal environment (e.g. cell division cycle, metabolism, infection status), and its specific role if in a multicellular organism. Gene expression can be regulated at any step: from transcriptional initiation, to RNA processing, to post-translational modification of the protein. The regulation of lactose metabolism genes in E. coli (lac operon) was the first such mechanism to be described in 1961.
answer:

When are genes expressed?
