Caspase 3/7 activity increases during normoxic development in embryos of <i>A. limnaeus.</i>

<p>Activity is expressed in relative luminescence units (RLU). Symbols with different letters are statistically different (Student Newman-Keuls, p < 0.05). The x-axis represents developmental time in days post-fertilization (dpf) for early embryos and days post-diapause II (dpd) for post-diapause II embryos. Symbols represent means ± S.E.M. (n = 3-4).
