It was shown that, in the course of colonization of temperate and cold climate zones by the honeybee, natural selection favored the acquisition of an effective mechanism of thermoregulation and high tolerance to hypoxia. It was noted that bees can develop under conditions when the CO2 concentration exceeds the content of this gas in the surface layer of the Earth by more than three orders of magnitude; however, this leads to deviations in the morphometric traits from the norm. At the adult stage, anesthesia with carbon dioxide was found to reduce the body weight and the water content in it.

Experimental data on the kinetics of specific antagonists binding to adrenergic and muscarinic receptors were analyzed by graphical and mathematical methods. The results suggest the presence of allosteric (cross-talk) interaction. In the control, α1- and α2-adrenoreceptors were represented by a single pool, and muscarinic receptors, by two pools. Two pools of adrenoreceptors with different affinity were detected against the background of serotonin. It was found that mianserin induces the formation of two pools of only (α2-receptors and muscarinic receptors are represented by two pools differing in the main parameters, such as dissociation constants and adrenoreceptor concentrations, in the control and experimental groups.
