Allometric growth in biology refers to relationships between sizes of parts of an organism (skull length and body length, for instance). If L;(t) and L2(t) are the sizes of two organs in an organism of age t, then L and L2 satisfy an allometric law if their specific growth rates are proportional: 1 dl1 - k dl2 L1 dt L2 dt where k is a constant. (a) Use the allometric law to write a differential equation relating L1 and L2 and solve it to express L, as a function of L2. (b) In a study of several species of unicellular algae, the proportionality constant in the allometric law relating B (cell biomass) and V (cell volume) was found to be k = 0.0792. Write B as a function of V. (Assume B corresponds to L, and V corresponds to L2.)

Allometric growth in biology refers to relationships between sizes of parts of an organism (skull length and body length, for instance). If L;(t) and L2(t) are the sizes of two organs in an organism of age t, then L and L2 satisfy an allometric law if their specific growth rates are proportional:
1 dl1 - k dl2
L1 dt
L2 dt
where k is a constant.
(a) Use the allometric law to write a differential equation relating L1 and L2 and solve it to express L, as a function of L2.
(b) In a study of several species of unicellular algae, the proportionality constant in the allometric law relating B (cell biomass) and V (cell volume) was found to be k = 0.0792. Write B as a function of V. (Assume B corresponds to L, and V corresponds to L2.)
