<h3>Myelin is an insulating layer, or sheath that forms around nerves, including those in the brain and spinal cord. It is made up of protein and fatty substances. This myelin sheath allows electrical impulses to transmit quickly and efficiently along the nerve cells.</h3>
Coral reefs are found in the photic zone of aquatic biome.
Explanation:
The ridges of ocean that are formed by invertebrates of marine system which lives in the superficial warm water are the Coral reefs. These are found in the ocean zone- photic. This is the uppermost surface area of ocean where abundance of sunlight is found and photosynthesis takes place.
The reefs of shallow water have an association with algae, which is photosynthetic. One of such reefs is the Reef of Great Barrier in the Australian northeast coast.

Answer:
Hydrogen
Explanation:
Elements that have low ionization energies tend to have low electronegativities. The nuclei of these atoms don't exert a strong pull on electrons. Similarly, elements that have high ionization energies tend to have high electronegativity values. The atomic nucleus exerts a strong pull on electrons.
