Compared to skeletal muscle, contraction of smooth muscle cells is a. only a slower response to a stimulus. b. only sustained without fatigue. c. only controlled by the somatic nervous system. d. a slower response to a stimulus and sustained without fatigue. e. a slower response to a stimulus, sustained without fatigue, and controlled by the somatic nervous system.

d. a slower response to a stimulus and sustained without fatigue.

Explanation:

The activity of the enzyme ATPase is slower in the smooth muscles as compared to the skeletal muscles as a result the production of ATP is also slow this can directly affect the response giving ability of the smooth muscles to the stimulus so there is an delay in the response given by the smooth muscles. The smooth muscle cells are involuntary. They use very little amount of ATP does during energy requirements they sustain without fatigue.

answer: although many types of viruses can cause a common cold, rhinoviruses are the most common culprit. a cold virus enters your body through your mouth, eyes or nose. the virus can spread through droplets in the air when someone who is sick coughs, sneezes or talks. theres your answer

explanation:
