Answer:

Option A, Release of chemical signals by keratinocytes that have been damaged by UV light will increase the production of melanin.

Explanation:

Negtaive feedback mechanism of homeostasis maintains the stability of any internal condition or function through lessening of output of a system or through slow down of a functional system.  

Here in this case the keratinocytes function is reduced by damaging them on exposure to UV light which further triggers the release of chemicals that enhance the production of melanin.

Hence, option A is correct

Chronic alcohol abuse will not only cause an individual to develop liver damage, but may also lead to cerebellar damage. Damage
aleksandrvk [35]

Damage to the cerebellum will cause the individual to appear clumsy and uncoordinated.

<h3>What happens if the cerebellum is damaged?</h3>

The coordination of voluntary motor action, balance and equilibrium, and muscle tone are all functions of the cerebellum. It is situated toward the rear of the brain, just above the brain stem. Compared to the frontal and temporal lobes and the brain stem, it is relatively trauma-resistant.

Slow and uncoordinated motions are the outcome of cerebellar damage. When walking, people with cerebellar abnormalities frequently sway and stumble.

A cerebellar injury can cause the following symptoms:

  1. loss of coordination of motor movement (asynergia)
  2. inability to judge distance and when to stop (dysmetria)
  3. inability to perform rapid alternating movements (adiadochokinesia)
  4. movement tremors (intention tremor)
  5. staggering, wide-based walking (ataxic gait)
  6. tendency to fall
  7. weak muscles (hypotonia)
  8. slur (nystagmus)
