Pretty sure it's all of the above
Answer:
The conditions that will not cause conduction deafness is <em>damage to cochlear hair cells, </em>option B.
Explanation:
Conduction deafness occurs there is an alteration that blocks the transmission of sound from the external and middle ear to the inner ear. It is a mechanical problem in the ear canal or the middle ear.
The outer ear is the external portion that collects sonar waves and directs them to the inner ear. Three structures compose the external ear, these are the auditory pavilion, the ear canal, and the eardrum. Damages in any of these parts might produce conduction deafness.
The middle ear is located between the eardrum and the oval window of the inner ear, to which it transmits sounds. the middle ear is composed of three little bones called ossicles, the oval window, the circular window, and the Eustachian tube. Any damage or alteration in this area will also cause conduction deafness.
There are different causes of deafness, such as earwax plug, <u>damage in the eardrum,</u> otitis, traumatisms or malformations, tumors, outer ear infections, <u>imflamation</u>, fluid accumulation, among others. Any of these might impede the properly sound conduction, thus the sound can not reach the inner ear.
Bioaccumulation refers to the accumulation of a toxic chemical in the tissue of a particular organism.
Biomagnification refers to the increased concentration of a toxic chemical the higher an animal is on the food chain.
The correct answer is - Most killer whales congregate in the areas that are near the Arctic/Antarctic Circles.
The killer whales have a very large distribution, and they can be found in all oceans, apart from the Southern Ocean. It is noted though that the population density of the killer whales differs from place to place. The higher concentrations are found around the Arctic and Antarctic Circles, where there's cool rich waters, while in the lower latitudes they are much rarer. The reason for this probably lies in the fact that most of the animals that are considered to be the prime food source of the killer whales are living in this rich cold waters.
