Classify the descriptions as being representative of either the somatic nervous system or the autonomic nervous system. a. voluntary controlb. one lower motor neuronc. stimulates skeletal muscle fibersd. involuntary controle. two lower motor neuronsf. innervates cardiac muscle and smooth muscle

The correct classification would be as follows:

Somatic Nervous System

a) Voluntary Control

b) One lower motor neuron

c) Stimulates skeletal muscle fibers

Autonomic Nervous System

d) involuntary control

e) two lower motor neurons

f) innervates cardiac muscle and smooth muscle

Explanation:

Somatic nervous system is a part of the peripheral nervous system that is responsible for the various functions such as voluntary movements of muscles. It is also responsible for the stimulating impulse in between central nervous system that include skeletal muscle.  

Autonomic nervous system is the part of the nervous system that is involved in bodily functions that function not consciously directed. Which is involved in innervates heart muscles and smooth muscles.

Thus, the correct answer is -

Somatic Nervous System

a) Voluntary Control

b) One lower motor neuron

c) Stimulates skeletal muscle fibers

Autonomic Nervous System

d) involuntary control

e) two lower motor neurons

f) innervates cardiac muscle and smooth muscle

clumped distribution, because you'de have all of the population gathered in a relatively small are.

it's the most common because it provides protection and a mate for reproduction

example: humans, seeweed, cattles, etc.
