Answer: Bundles of axons in the central nervous system are called a "tract"
Explanation:
Axons(nerve fiber) consist of long slender projection of neurons or nerve cells that conduct and transmit impulses away from the neuron or nerve cell body. Axons are surrounded by endoneurium layer which contain protein fluid that surround each axon.
Bundles of axon in the CNS is known as tract. We have ascending tracts and descending tracts. The ascending tracts function are to conduct and carry impulses along the spinal cord to the brain while the descending tracts transmit and carry the impulses from the brain to lower regions (downward) of the body. Tracts are identified by their origin (where the bundle start) and also the end/termination of axon bundle.
The largest tracts are fasciculi gracilis and cuneatus which are known as ascending tracts.
B; An unshelled fish is lively and elusive past the power of words to portray, and in this, undoubtedly, lies its desirability.
It is thigmotropism because it is not affected by gravity or light.
This would actually be known to originate in the "nucleic acid". This would have nothing to do with the DNA it's self, and also protein has nothing to do with it also.<span>Nucleic Acid would be small particals in the cells that would consists of molecules would some sort of chain which would then lead to the DNA, but it would actually have not resemblance of the nucleic acid at any point.
