Question

The nubers listed above are the options avaiable for each answear

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).

Explanation / Answer

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
