Answer:
<h3> Somatic: </h3>
- Skeletal muscle activation
- Voluntary
- Principally involved with movement "of" the body.
<h3>Autonomic: </h3>
- Can be excitatory or inhibitory on the target organ.
- Principally involved with the movement of materials through the body.
- Intestinal smooth muscle activation.
- Sweat gland activation
- Lacrimal gland activation
- Piloerector muscle
- Involuntary activation.
Explanation:
We can divide the nervous system into the central nervous system, which consists of the brain and spinal cord, and the peripheral nervous system, which consists of all the nerves that are throughout the body carrying information from and to the central nervous system.
We divide the peripheral nervous system into the somatic nervous system and the autonomic nervous system.
The somatic nervous system is the conscious one, that is to say, that we know and control what it does. It is voluntary. It has motor and sensory neurons that carry information to and from the central nervous system. The somatic nervous system is the one that makes us move our muscles to do an action.
The autonomic nervous system is involuntary. In other words, we can not control it consciously. It is the one that controls glands, organs, and smooth muscle, like the one that surrounds the digestive tract to move the food. As we can not consciously control it, this system can work exiting or inhibiting an organ depending on the situation.

Explanation:
The hypothesis that eukaryotic cells evolved from a symbiotic association of prokaryotes—endosymbiosis—is particularly well supported by studies of mitochondria and chloroplasts, which are thought to have evolved from bacteria living in large cells.
The classification system for organisms has changed from seven levels to eight. This happened because scientific consensus changed as scientists learned more about organisms.
Answer:
C.
Explanation:
In an ecosystem you have all the factors that contribute to a population of a variety of organisms. You have wind, water or sun as some abiotic factors which in turn help plants and trees survive with sustain different species.
