題組內容
2. As animals increase in physical size, their internal volume grows cubically (r³) while their outer surface area only increases quadratically (r²). This mathematical constraint presents a severe challenge for internal transport and metabolic maintenance.
c) Explain why simple diffusion across the outer body surface is sufficient for a microscopic single-celled organism, but entirely inadequate for a complex, multicellular mammal. (5 points)
