Many think that birds evolved from dinosaurs, they both have hollow bones, recent studies show that some Dinosaurs had feathers. if you were to compare the form of a Dinosaur to a chicken you would see that they walk and stand like each other. Also, the Genes show that they might have a distant relative. I hope this helps
Answer:
<h2>Ear has three main parts; outer most part is called outer ear, middle one is as middle ear and innermost as inner ear.
</h2>
Explanation:
1. Outer Ear: Pinna (the outer, funnel-like part), Ear Canal (Conducts sound vibrations from the pinna to the tympanic membrane), and Tympanic Membrane.
2. Middle Ear: Ossicles (Tiny bones that amplify sound waves), Malleus, Tensor Tympani, Incus (Connects the Malleus to the Stapes; receives vibrations from the Malleus and looks like an anvil), Stapes, Stapedius, Oval Window (Receives vibrations from the Stapes and is the flexible opening to the cochlea).
3. Inner Ear: Cochlea (The main structure in the inner ear; tiny coiled structure); Tympanic Canal, Vestibular Canal, Basilar Membrane, Cochlear Partition , Round Window Organ of Corti.
.
Route of Sounds: External environment → Collected by the pinna → Through the ear canal → Vibrates the Tympanic Membrane → Vibrates the ossicles → Vibrates the Oval Window → Sends “Traveling Waves” through the Vestibular Canal → Pressure released by Round Window if necessary → Inner and Outer hair cells transduce the vibrations.
