Which of the Following Represent(s)a Consequence of Surface-Area-To-Volume Ratio

Question

Which of the following represent(s)a consequence of surface-area-to-volume ratio?
A)When both a large and small bird of the same species hit a microwave tower while migrating at night,the small bird is more likely to die from loss of heat before it can recover from the mild trauma
B)A cup of tea poured from a large teapot cools off faster than the larger amount of tea left in the teapot
C)An amoeba needs no gills or lungs,an amphibian needs some small gills or lungs,but a horse needs substantial lung surface
D)All of the choices represent factors directly related to the surface-area-to-volume ratio

Accepted Answer

All the choices listed are examples of how surface-area-to-volume ratio affects different biological processes. Option A shows how smaller birds have a higher surface-area-to-volume ratio and therefore, lose heat more quickly than larger birds. Option B shows how a smaller volume of tea (with a higher surface-area-to-volume ratio) has more surface area exposed to air and cools faster. Option C shows how unicellular organisms like amoebae have a high surface-area-to-volume ratio, which allows oxygen and nutrients to diffuse across their outer membrane, while larger organisms like horses need specialized respiratory systems to ensure adequate gas exchange due to a comparatively lower surface-area-to-volume ratio.
