Physiology
OL 3. Scientists examining the bones of dinosaurs have found an interesting relationship. Comparing the leg bones of different species of dinosaurs, they find that the measured thickness of the bones increases disproportionally - as the mass of the animal goes up, the bones are far thicker than the simple mathematical relationship of volume increasing as a cube and thickness (i.e., overall cross-sectional area) increasing as a square. The strength of a bone is typically related to its thickness (cross-sectional area). In 1 sentence, describe why this is an example of "allometry" (look it up in Wikipedia), and in two sentences, describe why this relationship needs to exist.
