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:
Troponin
Explanation:
This is a complex of three proteins (Trop C, I, T) that are responsible for muscle contraction of the skeletal and cardiac muscles . its binds with protein tropomysin to lie in the grove between the actin filaments. its prevents contraction by blocking myosin crossbridge in a relax muscles.Inorder to aid contractions calcium ions binds with troponin, which leads to confrontational change.This exposes myosin on actin filaments, leading to formation of crossbridge and therefore contraction of muscles.
Therefore if there is a mutation in the gene that encoded Troponin, as explained above, calcium ion will not be able to bind with tropinin, and there will be no exposure of myosin on actin filaments, no binding of myosin on actin to cause crossbridge, and consequently no muscle contraction,
Thus the intercoastal muscle and diaphragm will not contract leading to death of the baby.
The reference point = a object used for comparison to determine if something is in motion.
An object is in motion if it changes position relative to a reference point.
You assume that the reference point is stationary, or not moving.
