It should be 2, pituitary gland. (: It's referred as the master gland.
I hope all is well, and you pass. Good luck, rockstar!
The ability to think logically about abstract propositions is indicative of the stage of __formal operations___.
According to Piaget Theory, Children develop cognitively and process information as they grow and mature in four stages which are
- Sensorimotor Stage
- Preoperational Stage
- Concrete Operational Stage
- Formal Operational Stage
The Formal Operational Stage spans from adolescence through adulthood. Here children develop from analyzing and interpreting concrete objects to improving their logic reasoning. They are able think and analyse abstract situations and hypothetical principles.

Answer:
Myelinated Axons; leak channels are insulated by myelin leading to less loss of current flow and better conduction velocity. Ion channels omly located at nodes of ranvier; thus signal has sultatory conduction along myelin sheaths and jumps and move much quicker
Demyelinating diseases; along locations where myelin sheaths once was current links occur and conduction slows, the signal cannot make it very far because it looses energy as it travels through the axon
Unmyelinated axon; Ion channels are sequentially placed all along axons; thus it takes longer to send signal down axon. the energy isn't leaked out, it still contains the same signal but it is simply slower. distance between voltage gated channels needs to be small enough so local current flow can depolarize the membrane.
N/B; Harder to generate action potential in demyelinating disease
axon diameter( bigger diameter= less resistance= faster current).
