Ms. waters is thinking about a discussion in class today that surprised her. she learned that if she burns her finger, for example, a simple pathway of communication occurs, from sensory neurons through interneurons in the spinal cord back out through motor neurons. this pathway is more commonly referred to as a(n):

This pathway is more commonly referred to as a reflex arc.

A reflex arc is the pathway of neurons that controls a reflex (an involuntary reaction to a stimulus).  A reflex arc involves a few nerve cells and the information is transmitted from the body to the spinal cord. There are two types of reflex arc which are; somatic reflex arc that affects muscles, and autonomic reflex arc that affects inner organs. Most reflex arcs are composed of sensory neurons, receptors, interneurons, motor neurons and muscles.

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
