The correct answer is sympathetic nervous system.
<span>
The sympathetic nervous system is a component of the autonomic nervous system, together with the parasympathetic system. Their functions are opposite but coordinate to maintain homeostasis. The sympathetic system has a role to control the body's response during perceived threat (fight and flight reactions). According to this, it dilates the pupils, contracts the muscles, increases heart rate...</span>

Ainat [17]

OPTIONS:

a)It is beneficial only to the males that do not fertilize eggs.

b)It is beneficial only to the female workers that are not fertilized.

c)It is beneficial to each one of the individual colony members.

d)It is beneficial to the whole species, but not to all of the individual members.

Answer:

d)It is beneficial to the whole species, but not to all of the individual members.

Explanation:

The behavior exhibited by the wasp is beneficial to the whole species, but not to all of the individual members as all wasps work all together to ensure the survival of newly fertilized females for the continuation of the species. All other wasps pay the supreme sacrifice working together in building nest, laying eggs, fertilization, all in a bid to ensure the continuation of their species, while most die leaving only the newly hatched females, that ensures continuation of the species.

our nervous system is organized into two broad anatomical divisions: the central nervous system (consisting of the brain and spi
vovangra [49]

Answer:

If you tap your knee, the signal to act is carried via your somatic nervous system to the muscles in your knee. In contrast, the signals that pass via the autonomic nervous system are involuntary and act primarily to regulate your body's internal environment. This involuntary nerve system is further organized into three divisions. If you need a sudden burst of energy, your sympathetic nervous system is activated to help you act quickly. In contrast, if you are relaxing and conserving energy, then it is your parasympathetic nervous system that is primarily in action. The third division is your enteric nervous system which helps control the components of the digestive system.

Explanation:

Peripheral nervous system (PNS) is the nervous system that contains nerves and ganglia outside the central nervous system (CNS). PNS is divided into:

  • somatic (voluntary) nervous system-controls the movements of the skeletal muscles
  • autonomic (involuntary) nervous system-controls the smooth muscles and glands and thus it is the regulator of the major body functions. It is subdivided into tree groups:
  1. sympathetic ("fight and flight") system-responsible for stressful and active situations (but also in normal conditions)
  2. parasympathetic ("rest and digest") system-opposite to sympathetic, responsible for the maintenance of body's activities at rest.
  3. enteric nervous system-controls the function of the gastrointestinal tract.
