dampen the vibrations of the tympanic membrane

2. The pitch of a sound depends on the ____of the sound wave.

3. Some animals, like humans, have two eyes on the front of the head that perceive a mostly overlapping visual field. In contrast, some herbivores (rabbits, for example) have eyes on the sides of their head and visual fields that may not overlap at all. How does this impact perception of the environment?

Humans have poorer depth perception and a wider field of vision than rabbits.

Due to integration by the brain, there is really no difference in depth perception or visual field size when comparing humans to rabbits.

Humans have better depth perception and a narrower field of vision than rabbits.

Humans have poorer depth perception and a narrower field of vision than rabbits.

Humans have better depth perception and a wider field of vision than rabbits.

horizontal cells​

​rods

​cones

​amacrine cells

​ganglion cells
