I believe this would be the correct order:
1) A receptor detects a signal.
2) A sensory neuron sends a signal to the spinal cord.
3) A relay neuron sends a signal to a motor neuron.
4) A muscle receives a signal to contract.
5) A bone moves.
A signal will be picked up by a sensory neuron and sent to the spinal cord (Central Nervous System). The signal will then be sent to a motor neuron in the Peripheral Nervous System to find a muscle. That muscle is signaled to contract which then will cause a bone to move.
The correct answer is water. Since carbon
is the common element of organic compounds, the molecule of
an organic material must have at least one carbon atom in its molecule. Water does not
contain any carbon atom in its molecule, H2O. So water is only an inorganic compound. <span>It is the most abundant and important inorganic compound in
living material. It makes up about 60-80% of the volume of most living cells.</span>
