A small desert rodent has a roughly spherical body with radius \(5\,\text{cm}\). A desert jackrabbit has a cylindrical body of length \(60\,\text{cm}\) and radius \(10\,\text{cm}\). Calculate the surface‑area‑to‑volume ratio (SA/V) for each animal and state which has the lower ratio. Explain how this ratio relates to their adaptation to the desert environment.

Answer Options

A. Jackrabbit has the lower SA/V (≈0.60 cm⁻¹) compared with the rodent (≈0.23 cm⁻¹); the lower ratio helps the larger animal conserve water and retain heat in the desert.
B. Jackrabbit has the lower SA/V (≈0.15 cm⁻¹) compared with the rodent (≈0.45 cm⁻¹); the lower ratio helps the larger animal conserve water and retain heat in the desert.
Correct Answer C. Jackrabbit has the lower SA/V (≈0.23 cm⁻¹) compared with the rodent (≈0.60 cm⁻¹); the lower ratio helps the larger animal conserve water and retain heat in the desert.
D. Jackrabbit has the lower SA/V (≈0.30 cm⁻¹) compared with the rodent (≈0.70 cm⁻¹); the lower ratio helps the larger animal conserve water and retain heat in the desert.
Correct Answer
C
Correct Option:
Jackrabbit has the lower SA/V (≈0.23 cm⁻¹) compared with the rodent (≈0.60 cm⁻¹); the lower ratio helps the larger animal conserve water and retain heat in the desert.
