Answer:
spinal cord
Explanation:
Reflex actions are the involuntary action of the body in response to a signal or stimulus. The reflex action of body is controlled by spinal cord.
Reflex arc acts as a neural pathways that transmit impulse to the brain via spinal cord. Sensory neurons pass through synapse in the spinal cord which activate spinal motor neuron to act immediately without any delay.
Immediate taking off hand from hot oven is an example of reflex action, which is regulated by spinal cord.
Hence, the correct option is spinal cord.

Explanation:
Answer:
D. GTP
Explanation:
Initiation of protein synthesis includes binding of mRNA to small ribosome subunit and initiation aminoacyl tRNA. The pairing of the anticodon of the initiating aminoacyl tRNA and initiation codon of mRNA requires GTP hydrolysis and marks the beginning of protein synthesis.
Elongation stage of protein synthesis requires movement of the ribosome along the mRNA which in turn is facilitated by GTP hydrolysis. As the ribosome moves along the mRNA, the codon of mRNA bind to the respective anticodon of aminoacyl tRNA by using the energy of GTP hydrolysis. The GTPase activity of elongation factor Ef-Tu ensures the fidelity of the process.
The release factors that recognize the stop codon and serve to mark the termination of protein synthesis use the energy of GTP hydrolysis during the process.
