Fig. 1. Thermogenesis of the early development of Xenopus laevis. An egg fertilized at t = 0 hr was loaded in the isothermal calorimeter at T = 295 K. The solid line represents the crystal growth model of eq. (3) with Avrami index n = 3/2.
Fig. 2. Arrhenius plots of the frequencies of the cell cycles, τ0−1(open circles, the activated oocytes; triangles, the fertilized eggs), the crystal growth rates τc−1 of the embryos (open squires), and the thermogeneses of the activated oocytes P (closed circles) at T = 288 K, 291 K, and 295 K.
