Question

Which of the following is a physiological adaptation?
a.
group hunting
b.
hyoid bone adapted for roaring
c.
dark coloration
d.
migration

Answer 1

None of the above.

Reason: physiological adaptations are internal functional changes (e.g., production of antifreeze proteins, regulation of body temperature, altered metabolism). The options are:
- a. group hunting — behavioral adaptation
- b. hyoid bone adapted for roaring — structural/anatomical adaptation
- c. dark coloration — morphological/structural adaptation (due to pigment)
- d. migration — behavioral adaptation
