Physiological process of regulators can tolerate large changes in internal conditions. Regulators invest little energy in opposing environmental variation. Physiological process of Regulators can tolerate large changes in external conditions. Regulators have physiological functions that are optimized for steady conditions, independent of external variation. Regulators maintain internal conditions at relative constant state, despite differences from and changes in external conditions. Regulators can survive in a wide variety of habitats. Regulators allow internal conditions to equal and change with external conditions.Identify the missing words in the below description.
