QUES: It is now known that the molecular circadian clock can function within a single cell; i.e., it is cell-autonomous. This was shown by Gene Block in isolated mollusk BRNs.[clarification needed] At the same time, different cells may communicate with each other resulting in a synchronised output of electrical signaling. These may interface with endocrine glands of the brain to result in periodic release of hormones. The receptors for these hormones may be located far across the body and synchronise the peripheral clocks of various organs. Thus, the information of the time of the day as relayed by the eyes travels to the clock in the brain, and, through that, clocks in the rest of the body may be synchronised. This is how the timing of, for example, sleep/wake, body temperature, thirst, and appetite are coordinately controlled by the biological clock.[citation needed]
How are sleep and wake cycles as well as body functions coordinated?

ANS: biological clock

The M65 motorway from Colne, connects Burnley, Accrington, Blackburn to Preston. The M61 from Preston via Chorley and the M66 starting 500 metres (0.3 mi) inside the county boundary near Edenfield, provide links between Lancashire and Manchester] and the trans-Pennine M62.

QUES: Between 1832 and 2002 the currency of Greece was the drachma. After signing the Maastricht Treaty, Greece applied to join the eurozone. The two main convergence criteria were a maximum budget deficit of 3% of GDP and a declining public debt if it stood above 60% of GDP. Greece met the criteria as shown in its 1999 annual public account. On 1 January 2001, Greece joined the eurozone, with the adoption of the euro at the fixed exchange rate ₯340.75 to €1. However, in 2001 the euro only existed electronically, so the physical exchange from drachma to euro only took place on 1 January 2002. This was followed by a ten-year period for eligible exchange of drachma to euro, which ended on 1 March 2012.
When did the physical exchange of the drachma to euro become illegal?
