Answer:

The correct option is<em> B) Meiosis provides for chromosomal variation in the gametes produced by an organism.</em>

Explanation:

Meiosis can be described as a cell division process by which the chromosome number gets reduced to half. This is because half of the chromosomes will come from the female parent and half of the chromosomes will come from the male parent in the offsprings that will be produced when they interbreed.

During the process of meiosis, crossing over and homologous recombination of chromosomes occurs which allows genetic variations among species.

What part of henry’s cochlea may have damaged hair cells? What part of henry’s cochlea may have functional hair cells?
mamaluj [8]

The henry's may have damaged and functional hair cells of cochlea in organ of corti.

Hearing and the Cochlea:

  • Sound waves that enter the ear go through the external auditory canal before they strike the eardrum and cause it to vibrate.
  • The incus receives sound vibrations from the malleus, also called "hammer," which is linked to the eardrum, and sends them on to the stapes.
  • The stapes is a framework that moves the oval window in and out. This motion is received by the cochlea, a fluid-filled snail-like structure that houses the organ of Corti, the hearing organ.
  • Small hair cells make up the lining of the cochlea. These cells convert vibrations into electrical impulses that sensory nerves then transmit to the brain. the Corti organ, which has four rows of hair cells. On the left, there is an inner row, and on the right, there are three outside rows.
  • The stapes first sways against the oblong glass. This causes sound waves to travel into the cochlear fluid and move the organ of Corti.
  • Lower frequency sound resonates with fibers towards the cochlea's upper end. Higher frequencies elicit a response from those near the oval window.
