Which of the following is true? the peripheral nervous system (pns) is located outside the brain and spinal cord. the central nervous system (cns) is composed of the brain and spinal cord. a nerve is a bundle of axons (nerve fibers) that lies outside the brain and spinal cord. ganglia are small masses consisting primarily of neuron cell bodies located outside the brain and spinal cord. all of these choices are correct.

Neelaredoxin is a 15-kda protein that is a gene product common in anaerobic prokaryotes. it has superoxide-scavenging activity, and it is constitutively expressed. in addition, its expression is not further induced during its exposure to o2 or h2o2 (silva, g., et al. 2001. j. bacteriol. 183: 4413–4420). which of the following statements best describes neelaredoxin synthesis? a-neelaredoxin is produced at all times; levels are constant even when exposed to o2 or h2o2.b-neelaredoxin is produced at all times; exposure to o2 or h2o2 increases expression. c-neelaredoxin is produced at all times; exposure to o2 or h2o2 decreases or prevents expression. d-neelaredoxin is only produced when there is exposure to o2 or h2o2.
