Answer:
The correct answer is "No, this is not consistent with the predictions on optimality".
Explanation:
The optimal foraging theory (OFT) establishes that an organism looks for the best foraging strategy, which involves maximizing the amount of energy that is available in its daily activities. In this case, the songbird species is not consistent with the predictions on optimality since it needs more calories than it intakes in order to defend its territory. In this scenario, the songbird will lose 72 calories per day.

Answer:
The radii of the arterioles constrict by humoral control and by nervous control.
Explanation:
The vascular system regulation is performed by the smooth muscle of the arterioles, which constitute the maximum resistance point. The smooth muscle relaxation provokes vasodilation, increasing its diameter. On the contrary, smooth muscle contraction provokes a decrease in the arteriole´s diameter, reducing the blood flow.
This muscle is under the control of the autonomous nervous system and certain hormones.
Substances such as adrenaline, noradrelanine, angiotensine, vasopresin, and endotelines cause vasoconstriction.
Also, there are many vasoconstrictor fibers of the sympathetic nerves that increase resistance and modify blood flow.
The ultimate donor is H2O, and the acceptor, NADP+. The energy that drives this electron flow is from light.
