Ostriches go through a large change in body mass as they grow from hatchlings to adults. Body mass increases 25-fold as the bird develops from a four-week hatchling to a full grown adult. The duration of a reflex loop (time from stimulus to response) depends on the distance (length) the signals have to travel and the conduction velocity of action potentials along axons. If the conduction velocity is directly proportional to the cross-sectional area of axons(A) by what factor does the cross sectional area of the axon have to increase in order to maintain a constant reflex duration as the animal grows?(B) By what factor would the cross-sectional area of axons increase under isometric scaling.

Assume that a person skiing high in the mountains at an altitude of h = 15100 ft takes in the same volume of air with each breath as she does while walking at sea level. determine the ratio of the mass of oxygen inhaled for each breath at this high altitude compared to that at sea level. assume that the air composition (i.e. % of air that is oxygen) is the same at sea level as it is at 15100 ft.
