Document Summary

Doubling linear dimensions in all directions increases volume by a factor of 8 and surface are by a factor of 4. How adhesive, diffusive & gravitational forces act on indv. How do different forces change as you increase in size. F= alb logf = loga +b log l -------> creates linear relationship, slope of the line is the exponent. The relative weakness of gravitational forces permit modes of growth impossible for large animals. Cross sectional area to muscle, bigger it is the and secrete a new one. A large mammal without any supporting structures would collapse to a formless bigger it is the more fibers it has structures would collapse to a formless mass under the influence of gravitational forces during a molt. Isometric scaling: all dimensions increase the same amount as the size of an organism changes. Allometric scaling: disproportionate growth of a part or parts of an organism as the size of the organism changes.
