(d) (i) A bat's body temperature during hibernation
is usually 4°C. This is often the temperature of
underground caves where bats prefer to hibernate in
winter. When a bat wakes up from hibernation its body
warms up slowly, one degree Celcius every two minutes.
How long would it take for a bat to warm up to 37°C
so that it could fly?
(ii) If you find a hibernating mammal during winter
you must not pick it up or disturb it. This could be
fatal for the animal. Can you explain why?
