Answer:
<em>The cochlea</em> is the structure which receives information from the hair cells of the inner ear and conveys that information to the brain's auditory system.
Explanation:
The cochlea can be described as a snail-shaped structure which is present in the inner ear. The main function of the cochlea is to receive sound information in the form of vibrations and convert these vibrations into nerve impulses so that our brain can help us to interpret the particular type of sound. The cochlea is hence known to be the auditory part of the inner ear due to its important function.
By definition, communicable diseases are diseases that can be passed from one person to another. Also, not all communicable diseases are caused by bacteria only nor virus only.

I believe that what is meant with the phrase "older explanation" is none other that superstition. Therefore, I will give you one superstitious belief which is now explained by science.
In Southeast Asia, people used to believe that St. Elmo's fire appears in remote areas because a bloody battle occured in that place leaving disembodied souls of the dead wandering there in the night and even in sunshine!
For generations, many people believed that this is a fact and some even say that these apparitions are diabolical or demonic in nature. So often, caution is advised to people whenever a ball of fire appears out in the open.
However, recent breakthroughs in the 21st century helped scientists to explain this mysterious phenomena. They found out that St. Elmo's fire is actually plasma, nothing special. Now, plasma is considered one of the states of matter! But mind you, it still does not explain why St. Elmo's fire seems to have a mind of its own!
Answer:
<h2>Sedimentary</h2>
Step-by-step explanation:
Sedimentary rocks are formed when layers upon layers of old sediments from river beds build up. They eventually form a rock. This rock is typically the softest of all the rock types, and therefore the best rock to hold fossils. Igneous rocks are rocks that are formed as a result of volcanic activity. They are created when lava cools. These rocks are unlikely to hold fossils because they are too hard. Metamorphic rocks are rocks that started out life as a different type of rock. They were then subducted under the earths surface where extreme heat and pressure actually changed hem into a different type of rock. Fossils are unlikely in this type of rock because all that heat and pressure has made the rock very hard. Because of this, the most accurate answer would be: sedimentary rock.
