A. integumentary, respiratory, digestive

B. Circulatory, respiratory, nervous

C. Integumentary, nervous, muscular

D. Circulatory, digestive, nervous

yeah, you are right. it is C

Explanation:

The diagram depicts a reflex arc which shows the pathway order of the reflex arc and the systems involved in the pathway. this is a somatic reflex arc (affecting muscles) The integumentary system is the first which is a organ system that is made up of the skin, hair, nails and exocrine glands. here, somatic receptors in the skin receives the stimulus, then afferent nerve fibers carry this signals to the spinal cord (nervous system: CNS and the PNS; the brain and spinal cord is under the CNS). this is the second system involved.

In the reflex arc, the action potential does not travel to the brain, so results are processed faster. these impulses synapse in the spinal cord. efferent nerve fiber then carry the motor nerve signals to the muscles (muscular system). the effector muscle that has been stimulated then brings about the response.

In summary, it is carrying sensory information from the receptor to the spinal cord and then response generated by the spinal cord is taken to the muscles. Analysis of the signal will then be done after the action with the brain receiving this sensory input.

yes!

because it has a type of fat that can make you extremely sick

helicase, i think thats it
