Answer:
A. Natural selection results in those individuals within a population who are best-adapted surviving and producing more offspring. The traits that promote survival are heritable.
Explanation:
Natural selection works on the genetic variations that are already present in the natural populations. Some organisms of a population are more likely to produce more offspring than the others. This is due to the presence of beneficial genetic traits in these individuals that impart survival and reproductive fitness to them. Natural selection favors those individuals. Over the generations, the frequency of the beneficial genetic trait in the population increases.
Conductive hearing loss occurs from either (1) blockage from the external ear or (2) damage to any components of the middle ear; hence the answer here is false. Hearing loss that results from damage to the inner ear or the vestibulocochlear nerve is called <em>sensorineural hearing loss</em>.
<em>The most common cause of sensorineural hearing loss is noise-induced hearing loss due to prolonged exposure to high decibel environments (i.e. machine workers). </em>

When it involves one sets of cones it is an inherited recessive trait.
