Which explains why the reflex reaction is important in certain situations? a. connect parts of the brain b. connect the brain to the spinal cord c. detect feel smell d. control muscle movement

d. Control muscle movement

Explanation:

Reflect reactions are important in certain situation because they can control muscle movement without having to go through a conscious process, this means that they immidiately happen, no matter if you want it or not, this can help us gaining time on actions that have to happen in order to help us prevent accidents and other dangerous situations, for example when you touch something really hot, you rapidly let it go, without you sending the sign to the muscle of letting go, your reflex reaction does it automatically saving you from a more profound burn.

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.
