Pax-6 usually causes the production of a type of light-receptor pigments. In vertebrate eyes, though, a different gene (the rh gene family) is responsible for the light-receptor pigments of the retina. The rh gene, like Pax-6, is ancient. In the marine ragworm, for example, the rh gene causes production of c-opsin, which helps regulate the wormʹs biological clock. Which of these most likely accounts for vertebrate vision?

An aviator is flying at 30,000 ft where the barometric pressure is 226 mm Hg. He is breathing 100% oxygen, his alveolar PCO2 is 40 mm Hg, and his alveolar water vapor pressure is 47 mm Hg. What is the alveolar PO2 of the aviator (in mm Hg)? (Assume that the respiratory quotient is equal to 1.)
