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.
Answer:
knowledge of the sequence product
Explanation:
A gene knockout is a technique used in molecular genetics to deactivate target genes in an organism in order to study their functions by reverse genetics (i.e., gene loss). Knockouts are generated by different methods including, for example, homologous recombination or site-specific nucleases (zinc-fingers, TALENS, CRISPR/Cas9). These techniques require to know a priori the sequence of each gene to be knocked out in order to target desired mutations. In the last years, the CRISPR/Cas9 tool has gained attention to knockout genes of interest because it is a genome editing system that can be easily used for deletion or insertion of bases.
It uses its potential energy and converts it into kinetic energy as it falls (the lower it is during the fall it will be mostly kinetic, however the higher it is during the fall it will be mostly potential energy)
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
