A dichotomous key is a tool you use in biology to know the identity of things in nature such as trees,flowers, fish or even rocks. This key has choices that follow each other in a progressive manner, where one choice led to the other until you identify the item.In this case, to identify Dogwood, you follow the below steps;

1b. Broad leaf = Step 2

2b. Simple leaf = Step 7

7a. Leaf bases attached opposite each other on branch = Step 8

8b. Leaves not lobed = Step 9

The key is (1b,2b,7a,8b,9b)

guajiro [1.7K]

Answer:

C) It has a long preganglionic fibers

Explanation:

Peripheral nervous system (PNS) is the nervous system that contains nerves and ganglia outside the central nervous system (CNS). PNS is divided into:

  1. somatic (voluntary) nervous system-controls the movements of the skeletal muscles
  2. autonomic (involuntary) nervous system-controls the smooth muscles and glands and thus it is the regulator of the major body functions. It is subdivided into tree groups:
  • sympathetic ("fight and flight") system-responsible for stressful and active situations (but also in normal conditions);contains short preganglionic fibers and long postganglionic fibers.
  • parasympathetic ("rest and digest") system-opposite to sympathetic, responsible for the maintenance of body's activities at rest.
  • enteric nervous system-controls the function of the gastrointestinal tract.
