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.

Answer:
Biodiversity: Tropical rainforests are areas of extremely high biodiversity compared to other ecosystems. Biologists estimate that tropical rainforests contain about 50% of the world's terrestrial plant and animal species, yet they encompass only about 6% of the world's land area.
Explanation:
Answer: B (Color blindness)
Explanation:
Typical red-green color blindness in human patients is caused by mutations on genes located in the X chromosome. These mutations act in a recessive manner. Since females have two X chromosomes, the presence of a mutation in a single one of them does not normally result in color blindness. Males, in contrast, have a single X chromosome and therefore the presence of a mutation is likely to cause the disease.
About the other options: Down‘s syndrome is a numerical chromosomal anomaly, not related to sex. Human blood type is a codominant trait. Finally, tail length in dogs is a polygenic trait not amenable to classic Mendelian analysis.
