From an evolutionary standpoint can you think of reasons why some animals, eyes consist almost entirely of rods other animals eyes have only cones and these of still others, such as humans have both cones and rods?
Some bird eyes can detect uv light. Uv light can be reflected by the urine of some other animals and by some fruits. How did the uv detecting animals evolve from birds who could not detect uv light
1.Explain why UV light can’t be seen by the
eye?
2.Explain why we can’t hear sound frequency

- The eyes of vertebrates and cephalopods are similar in structure and function. A difference between the vertebrate eye and the cephalopod eye is that the vertebrate eye has: a. an iris surrounding the pupil, whereas in cephalopods the pupil surrounds the iris. b. a lens that changes shape when focusing, whereas in cephalopods the lens moves back and forth to focus. c. a retina that moves in the socket when recording the image, whereas in cephalopods the retina changes shape when stimulated. d. a pupil that shrinks in size in bright light, whereas cephalopods have a pupil that enlarges in bright light. e. retinal synthesized from vitamin A, whereas cephalopods lack retinal.arrow_forwardLike other nocturnal carnivores, the ferret shown in FIGURE 33.13 has light-reflecting material in its choroid. Explain why the presence of reflective material in this layer of the eye maximizes the degree to which light excites photoreceptors. Explain also why having reflective material in this layer causes the perceived image to be somewhat blurry.

Similar to how retinal disparity offers 3-D moviegoers a way to extract 3-D information from the two-dimensional visual field projected onto the retina, the brain can extract information about movement in space by comparing what the two eyes see. If movement of a visual stimulus is leftward in one eye and rightward in the opposite eye, the brain interprets this as movement toward (or away) from the face along the midline. If both eyes see an object moving in the same direction, but at different rates, what would that mean for spatial movement?arrow_forward
