The divisions of the nervous system that have antagonistic actions, or opposing actions are a) motor and sensory. b) sympathetic and parasympathetic. c) presynaptic and postsynaptic. d) forebrain and hindbrain. e) central nervous system and peripheral nervous system.

B) sympathetic and parasympathetic

Explanation:

e autonomic nervous system also called the vegetative nervous system is part of the peripheral nervous system which inervates  smooth muscle and glands. Thus, it directly affects the function of internal organs and  regulates  functions such as the heart rate, digestion, respiratory rate,  urination etc. This nervous system control is  unconscious.

The autonomic nervous system is divided into: the sympathetic nervous system, the parasympathetic nervous system and the enteric nervous system.

Parasympathetic nervous system works when organism is at rest so it is known as system responsible for "rest and digest functions". On the other hand, sympathetic nervous system works at active and stressful situations and it is known as "fight and flight" system.

the genotypes would be 50% bb and 50% bb

the phenotypes would be 50% brown and 50% white. hope this : )

protocol for imps extraction focusing on membrane protein extraction, solubilisation, and purification.
