• B)smaller bodies can store proportionally more fat as insulation than larger bodies.
• C)larger bodies have a proportionally smaller surface area,and heat radiation varies with surface area.
• D)larger bodies have a proportionally smaller surface area,and heat radiation varies with volume.
• E)smaller bodies have a proportionally smaller surface area,and heat radiation varies with surface area.
