Which structure is at work when the body deals with reflex actions? meninges brain stem vertebral column spinal cord

The right answer is spinal cord.

When a stimulus, calling for an immediate response, is perceived by a receptor housed in a part of the body, the nerve impulse propagates on the afferent fibers towards the spinal cord or the brainstem. After the passage through one or more synapses of the motor neurons, the afferent response - in the form of a second nerve impulse - goes to the effector organ (muscle for example) or to the motor centers, upper or lower (medullary nuclei of spinal cord or central nuclei, muscle tone of the cerebellum, awareness of the cortex, etc.)

Reflexes are sometimes stimulated for diagnostic purposes, especially in the neurological assessment; each reflex corresponds to an area of the spinal cord.

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.
