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>
The question is incomplete as it does not have the options which are-
a. migration
b. genetic drift
c. mutation
d. stabilizing selection
Answer:
The correct answer will be option- migration
Explanation:
Migration refers to the long-distance movement of the individual, group and population. The migration enables the flow of genes from one population into another called gene flow. Migration is the strongest force of gene flow after selection.
In the given case, since the allele frequency of the population has changed due to the migration of the 200 snakes from a population of 5000 snakes, therefore, migration is the correct answer.
Answer:
the epicentre occurs directly above
Explanation:
the focus is where the earthquake starts down in the core, and the epicentre is where the shock reaches the surface of earth's crust
