Explanation:
In Active transport, an input of energy in the form of ATP is needed to transport substances against the concentration gradient, I. E it allow the movement of molecules from an area of low concentration to one of higher concentration. And hence it is called active transport because energy is required to drive this process.
Active transport is the opposite of passive transport, where molecules move from a region of higher concentration to a region of lower concentration without the input of ATP.
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 answer is B. Carbon atoms can bond to other carbon atoms. In fact, carbon has four electrons to form four bonds with other atoms, including carbon. Carbon is the most common and used element in the world because it makes up all living things. All four main macromolecules also contain carbon.
