How does the ear work (the three different segments in the ear)

1 answer:

7 0

The three different segments in the ear are the outer ear, the middle ear, and the inner ear. When you hear a sound, the vibration of the sound travels from the outer ear all the way to the inner ear where the sound is transmitted as information to the brain, and then you realize what kind of sound is heard. For instance, the blowing of a whistle or a school bell.

Which is a correct interpretation of the cladogram shown below?

nataly862011 [7]

A cladogram is an image or a diagram that shows us an evolutionary relationship between different organisms. Up at the top we find the different organisms and their names. Along the side is where we find their characteristics. Anything that is past each characteristic will have that characteristic as you move up the cladogram. This diagram also shows which organisms are most closely related to one another.

Please see the image for an example. In this example we can see that the Koalas evolved after the trout.

I hope this helps, Regards.
