Answer:
b. have names that indicate the location of the initiation and termination of the nerve impulses
Explanation:
The sensory and motor tracts are sets of nerve fibers that run inside the central nervous system; more precisely within the spinal cord and they are named according to the path their fibers have, that is, we will call them indicating from where they begin to where they arrive.
For example, the spinothalamic tract is a sensory tract that carries the sense of touch and pressure from the spinal cord to the thalamus.
On the other hand, corticospinal tracts are linked to isolated and specialized voluntary movements (especially from the distal part of the limbs) and descend from the cerebral cortex to the spinal cord.
As for the other options, I can say that they are incorrect because the tracts do not differ to the right and left of the cord in sensory and motor. Also, the tracts are located in the white substance not in the gray.

Answer:
Answer is A. Two hydrogen atoms join together to form a molecule of hydrogen gas.
Explanation:
The electromagnetic attraction existing between hydrogen and other electronegative atom, such as nitrogen or oxygen, is known as hydrogen bond. It can also be explained as the electromagnetic attraction occurring when hydrogen binds to a higher or larger atom such as nitrogen.
Note that , the bond existing between two hydrogen atoms resulting in the formation of a molecule of hydrogen gas is covalent bond. Covalent bond can simply be explained as the sharing of electrons.
