Answer:
Myelination
Explanation:
The covering of myelin around the axons is called the myelin sheath. This myelin sheath helps in transfer of information faster and also in complex processes of the brain. The process of myelination begins in the PNS (peripheral nervous system).
The myelinated section are seperated from each other with a gap called nodes of ranvier. Glial cells (oligodendrocytes) forms the myelin sheath in the central nervous system and schwann cells (glial cells) forms the myelin sheath in peripheral nervous system. The propagation of electrical impulse in the myelinated fibers is by saltatory conduction that is from one node to another.
Explanation:
Biome and the ecosystem are the words that are sometimes applied interchangeably to explain a particular kind of environment.
The biome represents the geographical region that has the same kind of ecological atmosphere, climate and mostly consistent collection of the species and it is made of a large number of ecosystems.
An ecosystem represents a particular element of the biome and a species that nearly interact in it.
