All of the planets in this solar system contain all of those elements, and it is quite likely that every planet throughout the galaxy is likely to contain all of these elements.

It does not contain carbon monoxide, but it will likely produce carbon monoxide when burned.
A group of axons in the CNS is most likely referring to the tracts of neurons that are found in the spinal cord.
This is a reflex that the peripheral nervous system was involved in. The prick was noted by sensory neurons which carried information into the spinal cord and synapsed with motor neurons which made you react, most likely by pulling away.
Yes they do, invertebrates have small nervous systems, which consist of many small brains. Because of the anatomy of their nervous systems and the lack of neurons, they are thought to have limited cognitive capacity, and this means that they are likely to not be capable of emotions like we feel. This is why scientists are unsure whether or not or to what degree they feel pain.
other nerve cells... The brain is made up of nerve cells (also called neurons). There are neurons both in the central nervous system (the brain and spinal cord) and the peripheral nervous system. The communication between neurons occurs with release of neurotransmitters (chemicals that affect the surface of neurons). The release of neurotransmitters occurs when an electrical impulse travels down the neuron and causes the neuron to "fire" off neurotransmitter. This electrical impulse is called an "action potential." The release of neurotransmitter can have one of two possible effects on the "receiving" neuron, depending on which neurotransmitter binds with which neuron. It can make the receiving neuron either more likely to fire (excitatory) or less likely to fire (inhibitory). The result of this activity in billions of neurons creates quite a symphony, including everything we call thought.

You could say there are 2, The Central Nervous System(CNS), & the Peripheral Nervous System (PNS).To be more inclusive, here is a list of human nervous systems:The Central Nervous System (CNS), the Peripheral Nervous System (PNS),the Somatic Nervous System (SNS), the Autonomic Nervous System, the Sympathetic Nervous System, and the Parasympathetic Nervous System.That would make a total of 6, although the Sympathetic and Parasympathetic are parts of the Autonomic Nervous system, which could mean a total of 4, and the Autonomic is itself a part of the Peripheral Nervous System, which would bring the total back to 2.The Central Nervous System is comprised of the brain and the spinal cord;the Peripheral Nervous System connects the CNS to other parts of the body, and is comprised of the Somatic Nervous System and the Autonomic Nervous System;the Somatic Nervous System includes all the nerves controlling the body's muscular system, and sensory nerves;the Autonomic Nervous System consists of motor neurons which control internal organs, and is comprised of two sub-systems, the Sympathetic Nervous System, and the Parasympathetic Nervous System;the Sympathetic Nervous System is involved in the fight-or-flight response, and the Parasympathetic Nervous System is involved in relaxation.
Most likely not, as they lack a central nervous system.
The likely word is the adjective anxious (nervous, worried).
