BIOL 1070 Study Guide - Midterm Guide: Torpor, Permafrost, Propylene Glycol
Document Summary
Below is a partially completed table of the time scale of responses to winter temperatures. Choose the answer below that best fits the missing information for blanks 1-4. Which statement best describes the data shown in the figure: body temperature decreased from 5 to 1 c between 5 to 6 hr at the same time metabolic rate declined from 35 to 20 ml o. 2 returned to the values observed at 0 hr: body temperature and metabolic rate were fairly constant until 5-6hr when there was a substantial decrease in body temperature (about -15 c) and metabolic rate (about ~3. 5 ml o. This data likely represents a seasonal hibernator, e. g. 2. The data may represent nightly torpor in an endotherm: the abiotic factors in the arctic prevent the growth of a wide variety of photosynthesizing organisms, however the ones that do survive are very well adapted.
