The correct answer about fine motor coordination.
Fine-motor coordination is the capacity to synchronise the actions of the eyes and hands in order to carry out precise manipulating motions. It requires the regulation of the body's tiny muscles (eye-hand coordination). The reflexive grab and avoidance behaviours, which become integrated and improved with advancing age and experience, appear to be the first precursors of fine-motor control.
The majority of manipulative tasks need the use of two hands working together. These actions are known as bi-manual ones. Uni-manual activities are actions like opening a door that need only one hand. The third category of manipulating activities is graphic, which includes things like handwriting and drawing.

Answer:
The skull protects the brain from any direct damage and the vertebrae helps keep the nerves in the spine in place and protected from damage. So the central nervous system is protected by the vertebrae and the skull.
An indicator species is an organism whose presence, absence or abundance reflects a specific environmental condition. Indicator species can signal a change in the biological condition of a particular ecosystem, and thus may be used as a proxy to diagnose the health of an ecosystem.
