Answer:
parasympathetic
Explanation:
The parasympathetic nervous system is the one that controls involuntary functions and acts. The nerves that integrate it are born in the brain, forming part of the oculomotor, facial, glossopharyngeal and vagus cranial nerves
Within its functions it controls part of the visual apparatus: When we are nervous or activated, we need to capture all the possible information about the medium or about a particular stimulus, so the <u>pupil dilates</u>. On the contrary, when we are relaxed, the pupil contracts because it is not necessary to capture too much information from the environment, which is also called myosis.

the process by which the structure of a biological community evolves over time. Two different types of succession—primary and secondary—have been distinguished. Primary succession occurs in essentially lifeless areas—regions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunes, or rocks left from a retreating glacier. Secondary succession occurs in areas where a community that previously existed has been removed; it is typified by smaller-scale disturbances that do not eliminate all life and nutrients from the environment.
Steve is dead. Steves heart has stopped beating probably because his internal organs were damaged leading to low supply of blood. If the heart is not beating and he is not breathing it means he is dead.
Answer:
Pass information by generating electric signals
Explanation:
Neurons are the fundamental unit of the nervous system. Neurons send information across the body through generation of electric signals called as action potential. There are basically three types of neurons
a) Sensory neurons which carry information from the sense organs in the form of impulse to the central nervous system (CNS)
b) Motor neurons – These carry information from the CNS to the body parts such as sense organs, muscles etc.
c) Interneurons – They are connecting neurons which are responsible for transferring information from one neuron to the other neuron.
