Answer:
The cochlea contains of tiny stereocilia, or tiny hair cells.
Explanation:
By definition, cochlea is a snail-shaped portion of the inner ear, that belongs to the auditory system. Cochlea receives the vibrating sounds and it causes <em>stereocilia</em> (bundle of tiny hairs, visible in that shape only under the microscope) to move. Then, those vibrations are converted into nerve impulses, and further sent to brain so the received nerves can be processed.
That hearing is an extraordinary process, says the fact that we have over 15000 tiny hair cells! When sounds are too loud for too long, these bundles of <em>stereocilia</em> can be damaged. The damaged hair cells can't respond to sound, which causes noise-induced hearing loss. Since hair cells can’t be repaired or even replaced in humans, hearing loss is often permanent.

Answer:
The consumption of alcohol or alcohol flavoring.
Explanation:
In research, we usually have two different types of variables:
- The independent variable is the one that the researchers can control and that will have an effect on another variable.
- The dependent variable is the one that cannot be control and that is affected by the independent variable. Researchers observe this variable to see how it changes. This is the variable that will be tested or measured.
In this example researchers told some subjects they were receiving alcohol and to some others they were not receiving alcohol and measured their physical coordination and mental capacities. We can see that the researchers could control the amount of alcohol the participants were going to consume and the coordination and mental capacities would be affected by this consumption. Therefore, since <u>the consumption of alcohol </u><u>will have an effect on the other variable</u>, this would be the independent variable.
