Answer:
All of the above.
Explanation:
For the study of protected animal species, biologists should follow some steps. Those animals which are in protective condition are placed in the natural environment so that they can live their natural life and can reproduce easily. So, for inspecting the animals in their area, the biologists should move on to the area where they live. Along with this, they have to apply for permission to enter into the habitat of the animals because they are protected. We know that entering into a protected area is not possible without permission.
It's a mixture, hope it helps!
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.
