Fig. 1. (A) Resting metabolic rates (RMR) as a function of chick age. Filled
circles represent androgen-injected (T) chicks; open circles represent
oil-injected (Oil) chicks. For clarification, the open circles have been
plotted slightly to the right of the closed circles. (B) Mass-specific
metabolic rates for T (filled circles) and Oil (open circles) chicks as a
function of their age.
