Question

This is NOT TRUE concerning animal strategies for surviving subzero temperatures:

a. Bats in hibernacula maintaining a relatively high heart rate but lowering their body temperature

b. Yellow Warblers migrating to warm, southern areas

c. American Toads burying themselves in the bottom of ponds before they freeze over

d. Black Bears lowering their heart rate to 8 beats per minute while maintaining a high body temperature

e. Spring Peepers and Wood Frogs allowing some of the intercellular (between cells) water inside their body to turn to ice

Answer 1

The statement that is not true about animal strategies for surviving subzero temperatures is that bats maintain a relatively high heart rate while lowering their body temperature during hibernation; they lower both their heart rate and body temperature.

Step-by-step explanation:

The statement that is NOT TRUE concerning animal strategies for surviving subzero temperatures is: a. Bats in hibernacula maintain a relatively high heart rate but low body temperature. Bats, like other animals entering hibernation, lower both their heart rates and body temperatures to conserve energy during periods when food is scarce or temperatures are too low for their usual metabolic processes. Other strategies by animals to survive the cold include migration, burying themselves, reducing their heart rate significantly while maintaining a higher body temperature, and having physiological adaptations like antifreeze-like chemicals in their fluids.

For example, black bears lower their heart rate to minimal beats while still maintaining a high body temperature to conserve energy during the cold months. Yellow Warblers migrate to warmer southern areas to escape the harsh winter conditions. American Toads bury themselves in the mud at the bottom of ponds to insulate against the freezing temperatures. Furthermore, Spring Peepers and Wood Frogs have special chemicals in their cells that prevent them from freezing and bursting, acting like natural antifreeze.
