<span>The salmon is among the most revered of coastal animals, for its cultural and spiritual importance to First Nations, its world-famous tasty flesh, and its role in the historical economy of BC. The most common salmon in our local waters are Chum and Coho. All Pacific salmon species are anadromous, meaning they spend most of their life in the ocean but migrate to fresh water to breed. Consequently they interact with several different ecosystems, and play important roles in terrestrial, freshwater and marine food webs.</span>
Answer:
The coral reefs of the Caribbean are thought to be under threat
Explanation:
Overfishing threatens over 60 percent of Caribbean coral reefs. Declines in coral cover and increases in algal cover have been observed across the region. This analysis identified about one-third of Caribbean reefs at high threat from overfishing pressure and about 30 percent at medium threat.
Answer:
Myelination
Explanation:
Myelin is a fatty substance composed of lipids which surrounds the axons of the nerve cells in the central nervous system. The myelin is formed by the oligodendrocytes in CNS and Schwann cells in PNS.
The plasma membrane of the oligodendrocytes containing the myelin covers the axons of the neurons in spiral fashion thus proving a sheath around through the process called "myelination".
This myelin sheath protects the neurons from the external environment as well as insulates the neuron which increases the efficiency of the impulse.
Thus, Myelination is the correct answer.
