Which is a function performed by the central nervous system ( CNS) select all that apply

The Central Nervous system is made up of the brain,the control units,and the spinal cord ,the network of nerves ,which feed the brain with sensory information  for processing.The entire CNS is lined by a constantly circulating fluid called the Cerebrospinal Fluid.(CSF).

Together with the Peripheral Nervous system,the CNS ensure coordination of the body activities.

Generally both  the brain and the spinal cord are protected by the skull and vertebral column respectively. Their activities are based on the million of neurons which are networked by synapses.

Functions are:

processing information that is received from the stimuli receptors

sending out information so that the body can react appropriately to stimuli

coordinating reflexes and reactions to stimuli.

These functions are performed through the fast reflex  pathways, for efficient  coordination of the systems of the body by the CNS with PNS

Explanation:

you are certainly talking about this picture:

a: is the label of the white square, it is showing the  replication fork, formed by helicase (d) ==> so it is the site of dna separation and replication 

b: is a new dna brand that is following directly the replication fork, so it is continuous ==> built continuously from 5' to 3

c: dna polymerase cannot replicate dna on its own, it needs the of their proteins, and one of them plays the role of a clamp which fixes  the dna with the dna template and increases  the processivity of the enzyme. ==>   stops polymerase from falling off the  template.

d: is the enzyme responsible for forming the replication fork (helicase) ==> unwinds and separates dna into two strands

e: is the delayed strand, it is built  in the opposite sense of the helicase, so dna will be built in fragments ==> built  fragments from 5' to 3 joins

and finally f: is the enzyme that builds  the new dna strand (dna polymerase) ==>   adds nucleotides to make a new dna helix.
