Answer:
<h2>
The speed of action potential propagation get slower down</h2>
Explanation:
Myelination is the process of generating myelin in neurons. In CNS, oligodendrocyte make the myelin sheath.
The main function of myelin is to increase the speed of electrical impulses along the myelinated fiber.
Myelinated fibers lack voltage-gated sodium channels along the myelinated internodes, having them only at the nodes of Ranvier though which the molecules moves.
Demyelination is the loss of the myelin sheath, result due to some neurodegenerative autoimmune diseases, resulting in the decrease of the speed of action potential propagation.
Answer:
DNA is one of the major sources might be wrong tho
Explanation:
DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are. Biogeography. The global distribution of organisms and the unique features of island species reflect evolution and geological change.
Answer:
A Recessive
Explanation:
Generally, there are two types of disorders, progressive and recessive. When something is recessive, it is not a dominant gene. The reason why sickle cell anemia is classified as a recessive disorder is because it only affects some people, but it does not affect all those who share DNA. Hope this helps!
