question 12
which of the following is most similar in function to whale blubber?
a a bird’s feathers
b a snake’s scales
c a bat’s brown fat
d a bat’s white fat

Explanation:

For the first question: Dehydration reduces body water, increasing solute concentration (high osmolarity) and decreasing blood volume (low blood pressure). For the second question: Whale blubber is white fat for insulation; a bat’s white fat has the same insulating function (brown fat generates heat, feathers/scales have other primary roles).

Answer:

C. high; low
D. a bat's white fat
