Solution
The correct option is B Low surface area to volume ratios
- Allen's rule states that in a warm-blooded animal species(for example, mammals) having distinct geographic populations, the limbs, ears, and other appendages of the animals living in cold climates tend to be shorter than in animals of the same species living in warm climates.
- According to Allen's rule body form or shape is linear in warm climates and more rounded and compact in cold climates. Round forms have a smaller surface area to volume ratios.
- Hence As per Allen's rule, mammals of cold regions conserve body heat through the low surface area to volume ratios.
- So, the correct answer is 'surface area to volume ratios'.
