the month, or the year. They are affected but little, if at all, by drugs,
chemical, or wide temperature differences—factors may alter substantially 【M3】______
the rates of all ordinary processes of the body.

quite different theories have been advanced to account to them. According 【M5】______

selection, an adaptation to the rhythmic environment. It has now 【M6】______
become independence on the environment. According to this view, the clocks 【M7】______
are not perfect timers. They require regular corrections by the natural light
and tide cycles and the changed lengths of the day throughout the year. 【M8】______
The other theory holds up living things react continuously to their 【M9】______
rhythmic physical environment. The setting of their biological clocks,
therefore, involves a constant adjustment to subtle clocks are potential 【M10】______
perfect timers. [br] 【M3】
