(A)An adaptation is a characteristic that helps an animal survive in its habitat. All animals must be able to obtain food and water, protect themselves from harm, withstand the climate, and reproduce young so the species doesn't become extinct. ... Without their adaptations, the species could not thrive in that environment.
GIRAFFE-That ability – coupled with the tongue's impressive reach and its tough skin – allows giraffes to selectively browse, plucking leaves from among the nasty thorns brandished by many of its preferred food trees, such as acacias.
The degeneration or failure of hearing neural pathways to the brain which can occur with aging is called presbycusis, while the condition of hearing a ringing or roaring in the ears is called tinnitus.
Presbycusis is the normal hearing loos that occurs with aging. The hearing ability is more affected for high-pitched sounds. Low-pitched sounds either are affected very less or are not affected at all. The areas inside the body that may be affected to cause presbycusis are: Inner ear, middle ear or the nerve pathways to the brain.
Tinnitus is the continuous sound of ringing audible to the ears. It can be caused as a result of some other disease or due to other reasons like exposure to loud sounds, whiplash, head injuries, excessive ear wax, or medication side effects.

Let's take the example of touching something hot:
there's sensory nerves in all our body, including our hands and fingers. When a finger touches something hot. a nerve impulse will be born due to the stimulus and will be transmitted from the sensory nerves in the finger to the CNS (central nervous system)
The CNS will integrate the information, then transmit nerve impulses through the motor nerves which goes to the muscles of the finger (which are skeletal muscles) to order them to contract, to avoid the contact between the finger and the hot thing. (the same map for the blinking eye)
