With regard to thermoregulation in humans, what could be considered an accurate consequence of the outside temperature dropping below the lower critical temperature? A. The individual will begin to breathe in less oxygen and exhale less carbon dioxide. B. The metabolic needs of the individual will increase if they remain below the lower critical temperature for sufficient time-frames. C. Capillaries (i.e. blood vessels) near the surface of the skin will dilate in order to allow blood to circulate more freely throughout the organism, distributing heat to raise temperature. D. The person's Basal Metabolic Rate will be lowered to match the Standard Metabolic Rate of an ectotherm of comparable size. E. Hormones from the hypothalamus will be released, which lead to the initiation of a positive feedback response that amplifies muscle contraction, leading to shivering.
