Quantitative methods applied to biological phenomena lend themselves to hnalyses of the determining physical and chemical processes which might otherwise escape investigation. Prediction of results on the basis of such analyses may then be experimentally tested. Many types of animal behavior are det

## Abstract It has long been suspected that urea accumulation plays a key role in the induction or maintenance of metabolic suppression during extended dormancy in animals from diverse taxa. However, little evidence supporting that hypothesis in living systems exists. We measured aerobic metabolism
Lymnaea stagnalis were exposed to hypoxic and chemical challenges while ventilation, heart rate and metabolism were monitored. Hypoxia increased ventilatory behavior, but this response was eliminated by immersion in 0.75 mM nitric oxide synthase (NOS) inhibitor, 7-nitroindazole (7 NI). 7 NI also sup
## FOUR FIQTJRES I t has been stated that frog muscles in good condition have a low oxygen consumption, whereas those in poor condition show a high rate of oxygen absorption. Apparently, the death of muscle cells involves a, marked acceleration of respiratory metabolism (Fenn, '30). Similar sponta
