Explanation:

Question 8

Negative feedback in the body is a regulatory mechanism that aims to maintain a stable internal environment, known as homeostasis. Controlling body movement (A) is related to the muscular/nervous system's motor functions, not feedback. Keeping blood sugar high (C) is not the role of negative feedback (negative feedback would lower it if too high). Regulating excretion (D) is more about organ systems like the urinary system, not the primary role of negative feedback. So the result of negative feedback is to maintain homeostasis.

The "fight - or - flight" response is mediated by the sympathetic division of the autonomic nervous system. The somatic nervous system (A) controls voluntary movements. The parasympathetic division (not optioned as a correct choice here, and the cerebral option is incorrect) is for "rest - and - digest" functions. So the sympathetic division is responsible for preparing the body for "fight - or - flight".

Ganglia are collections of nerve cell bodies outside the central nervous system (CNS). Nuclei (A) are collections of nerve cell bodies within the CNS. Nerves (B) are bundles of axons. Tracts (D) are bundles of axons within the CNS. So the correct answer is ganglia.

Answer:

B) to maintain homeostasis
