Cochlea.
The part of the ear where sound wave compressions and rarefactions cause the eardrum to vibrate is the middle ear. The 8th nerve in the inner ear actually converts the mechanical energy to electrical energy for transmitting to the brain. A membrane called the tympanic membrane separates the middle ear from the outer ear. Whenever a sound reaches the ear, it creates a sound wave that creates vibration in the eardrum. The pressure when high pushes the membrane inwards while low pressure sound waves helps the eardrum to come outwards. <span>
These sound waves are then transduced when it reaches the cochlea where hair-like structures interprets the sensory information and is relayed to the brain.</span>
Answer:
A.
Explanation:
An allele is a variant form of a given gene.
Mediastinal shift occurs in Tension pneumothorax. A tension pneumothorax makes the lung to collapse and the heart, the trachea and the great vessels, to shift toward the unaffected side of the chest. When air moves out from a laceration in the lung and goes in the pleural space or infiltrate the pleural space over a wound in the chest wall the shift happens.
The value of the dependent variable is based upon changes in the values of the independent variable.
<h3>What is the dependent and independent variable?</h3>
The term independent variable has to do with the variable that is being intentionally manipulated in an experiment. The dependent variable is the variable that changes in value as the independent variable is manipulated.
Now, the question is unclear however, we do know that in an experiment, the value of the dependent variable is based upon changes in the values of the independent variable.
