Answer:

c) degree of myelination of the axon

Explanation:

The myelin sheath covers many axons in central nervous system (CNS) ( by oligodendrocytes) and in the peripheral nervous system (PNS) (by Schwann cells). Their function is to insulate axons and to increase the speed at which information travels from one nerve cell to another.

Nerve conduction velocity is specific to each individual and depend on the level to which that axon is myelinated, but also on  an axon's diameter.

In many areas of the world, wood is the easiest fuel to use for heating and cooking
cupoosta [38]

Answer:

B. It will affect more forest habitats as people need larger supplies of wood.

Explanation:

If wood is the easiest fuel for heating and cooking and people use it really common and if the human population grows, wood will run out easily. Wood is a limited supply as there isn't an infinite amount of trees in the world, trees normally take ten to twenty years to fully grow and there are billions of people in this world, but not billions of trees. Trees are also being cut down not only to use it as fuel to heat up things and cook, but also to have much more space for estates, malls and places.
