Which autonomic system is most likely to be dominant while someone is experiencing stress about an upcoming job interview? a) the peripheral nervous system b) the sympathetic nervous system c) the somatic nervous system d) the parasympathetic nervous system

the answer is the sympathetic nervous system i got that answer on my test

The correct answer is Sympathetic nervous system.

Sympathetic nervous system is the branch of Autonomic nervous system. It is activated in situations like emergency, anxiety, stress, and danger. This nervous system produces fight or flight response during such situation. It activates adrenal gland to release epinephrine and norepinephrine hormones. These hormones inturn produces physiological response to the situation ( like increase in heart rate).

According to the question, as someone is experiencing stress about a job interview. Thus, sympathetic nervous system will be dominant in this condition.

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
