Kleiber was trying to demonstrate that basal metabolic rate scales in proportion to Mass to the 3/4 (exponent). Instead he discovered that BMR scales in proportion to Mass to the 2/3 (exponent). The number of cells in an animals scales in proportion to Mass to the 1/4 (exponent). From these measurements we can calculate that the cellular BMR of animals scales in proportion to Mass to the 2/3 (exponent). The surface area of animals scales in proportion to Mass to the (exponent). The volume of animals scales in proportion to Mass to the (exponent).

Solution

Kleiber was trying to demonstrate that metabolic rate scales to the 2/3 power of the mass. Instead, he discovered a power of 3/4.

The number of cells scales in proportion to mass is 1/4. Thus, the proportion to cellular BMR to mass is 3/4.

The proportion of surface area to mass is 2/3.

The proportion to volume to mass is 3/4
