Imagine a very tiny person is walking through the auditory tract, from the ear canal through to the auditory nerve. when that tiny person reaches the cochlea and walks along the basilar membrane, Loud frequency sounds will disturb their walk most at the base of the cochlea, and soft frequency sounds will disturb their walk most at the tip of the cochlea, the cochlea communicates with the middle ear by two holes closed by membranes: the oval window, which limits the base of the vestibular ramp and on which the abutment is attached and the round window that closes the base of the tympanic ramp and which serves as a decompression system.

Recent photographs of the planet Mars reveal deposits that suggest the former presence of liquid water. How does this compare wi
kolezko [41]

Answer with Explanation:

Let's start first with water on the Earth's moon. This is called "lunar water."

The moon was thought to be barren by scientists long time ago. However, they found out that there are actually <em>water reserves located in the shadowed craters.</em> It is said that the formation of this water was possible with the existence of <u>Oxygen atoms in the lunar rocks and minerals. </u>Due to the <u>solar wind</u> that blew into the place, <u>the Hydrogen ions from the wind combined with the Oxygen in order to form water.</u> So, the water that is found here is relatively fresh.

Let's go to "water on Mars." This is said to be <em>more older than the water on the moon</em> and is actually not that pure for it consists of some mixtures of rocks. It is said that billions of years ago, Mars had an abundant supply of water, but due to climate change, the supply didn't last long. As a result, the planet dried out and only the areas in the polar and mid-latitude regions have water<em> (in the form of ice).</em> This ice melts and refreezes, depending on the temperature. This is an evidence that people may possibly live on Mars.
