Q22: Almost a decade after New York State passed laws to protect patients by reducing the grueling hours worked by medical residents, twelve hospitals have been investigated by state medical officials, finding that all twelve consistently break the laws, many residents work longer than 24 hours straight, and that more than half the surgical residents work more than 95 hours a week. 21

Diatoms of this species, sometimes called “commuter” diatoms, remain (10) burrowed in the sand during high tide, and emerge on the sand sur- face during the daytime low tide. Just before the sand is inundated by the rising tide, the diatoms burrow (15) again. Some scientists hypothesize that commuter diatoms know that it is low tide because they sense an environmental change, such as an alteration in temperature or a change (20) in pressure caused by tidal move- ment. However, when diatoms are observed under constant conditions in a laboratory, they still display periodic behavior, continuing to bur- (25) row on schedule for several weeks. This indicates that commuter diatoms, rather than relying on environmental cues to keep time, possess an inter- 22

nal pacemaker or biological clock (30) that enables them to anticipate peri- odic changes in the environment. A commuter diatom has an unusu- ally accurate biological clock, a consequence of the unrelenting (35) environmental pressures to which it is subjected; any diatoms that do not burrow before the tide arrives are washed away.
