Determine the following passage is an argument. Identify the conclusion. For those that are not, determine the kind of non-argument.
The brain and the nervous system are composed of two types of cells- neurons and glial cells. Neurons are responsible for information transmission throughout the nervous system. Glial cells constitute the support system for the neurons. For example, glial cells take away the waste products of neurons, keep the neurons' chemical environment stable, and insulate them, allowing 1 neurons to do their work more efficiently.
