You are in the forest and see a large, snarling, drooling grizzly bear running directly toward you. The adrenaline rush you feel as you run toward the cabin is controlled by the sympathetic nervous system.
The sympathetic nervous system is a part of the autonomic nervous system which functions through various interconnected neurons. The sympathetic nervous system’s main role is to stimulate the neuronal and hormonal stress response (also known as body's fight-or-flight response). The sympathetic fibers in the adrenal medulla (inner part of the adrenal gland) produce acetylcholine (a neurotransmitter), which allow the high secretion of adrenaline and low amounts of noradrenaline from it. The sympathetic nervous system also prepares the body for action, especially in situations that are dangerous to survival.
Answer:
Archaebacteria
Explanation:
Archaebacteria is a group of single-celled organism present on the earth which are thought to be descended from the ancient bacteria.
These bacteria can survive the extreme or harsh conditions present on the Earth-like in the hot springs.
The archaebacteria cell membrane is made up of ether-linked phospholipids which are ester-linked in Eubacteria and eukaryotes. The sugar present in the archaebacteria is very similar to peptidoglycan in composition but it is not peptidoglycan.
Thus, Archaebacteria is the correct answer.

Explanation:
The correct answer is: B. spinal cord
The nervous system can be divided into two subdivisions: the central nervous system (CNS) and the peripheral nervous system (PNS). The spinal cord and the brain are part of the CNS, whereas the PNS consists of the nerves that radiate from the CNS to all parts of the body. The PNS includes all neurons that sense and transmit information to the CNS.
The CNS controls thinking processes, movements, and registers the sensations throughout our body. Moreover, the PNS acts to transmit information from the CNS to all parts of the body.
The PNS is in turn divided into two main parts:
1-The Autonomic nervous system (ANS), which regulates involuntary functions and glands. The parasympathetic nervous system is one division of the ANS that controls visceral organs such as glands.
2- Somatic nervous system (SNS), which regulates voluntary muscle movement and transmits information from eyes, ears, and skin to the CNS.
