Please answer the following question: Process:  - Electrical signals in the brain travel through nerves to muscles - Two types of proteins exist in filaments in the muscles - The filaments move when the brain instructs them to - The motion of the filaments cause the muscle to shorten and contract - Opposing pairs of muscles exist in order to provide the necessary range of motion.  Perturbation hypothesis: suppose more exercise occurs happens, how will it affect muscles contracting MORE INTENSELY.  Does the supposed perturbation have an effect (direct or indirect) on the process?
A:
yes
