Fig. 4. Rates of protein synthesis in embryos (open circles), unfed larvae (open
squares) and fed larvae (filled squares) of the sea urchin L. pictus.
Each data point is the mean ± 1 s.e.m. of 5-6 determinations; where not
shown, errors fell within the graphical representation of the data point. The
fitted line shows an increase in rate of protein synthesis for fed larvae:
y=0.25e0.23x (r2=0.96).
