Rhodopsin is quickly inac- tion"—the process by which we only gradually become tivated in the presence of able to see objects in a brightly lit place after being in the dark?

bright light so rods be- come unresponsive, and the higher-acuity cones then become the main de- tectors of vision.

  1. The frequency of a perceived sound depends on which part of the basilar membrane resonates.

the inertia of the otoliths relative to the hair cells of the maculae.
