Len [333]
Well, personally I think that it is flawed: it limits the inflow of new ideas into politics.
I think that one way to address it is to abolish the electoral college and introduce country-wide representative elections and not a "winner takes it all" system.

Our ability to be aware of some parts of our environment while ignoring other parts is called:
Marat540 [252]
It's called selective attention. It consists of a very selective attention as the name sáis because we focuse on a single thing ignoring the rest, and that's why it is called that way. Most human beings have this type of attention because they focuse on a single thing, sometimes this attention is better for concentration but some others we also need to focuse in more than one thing to get a better result. You can work on your selective attention to improve it so you can focuse on the important things, there are various methods to do it and from my point of view are very useful. Hope this answered helped you and have a great day.

rosijanka [135]

Answer:

a. Cooperative

b. Antagonistic

c. Cooperative

d. Antagonistic

Explanation:

The autonomic nervous system (ANS) is a control system that is responsible for controlling the body's unconscious functions (e.g., digestion, respiratory rate, heart rate, pupillary response, sexual arousal, etc). The ANS is divided into the sympathetic nervous system and the parasympathetic nervous system. The sympathetic nervous system comprises nerves from the thoracic and lumbar segments of the spinal cord (responsible for fight or flight); whereas the parasympathetic nervous system is composed primarily of the cranial and sacral spinal nerves (responsible for controlling many of the body's functions when it is at rest). Moreover, antagonistic innervation occurs when an organ is controlled by two different types of nerves, i.e., dual innervation of the organ by both divisions of the ANS, where the effects of the sympathetic and parasympathetic divisions are antagonistic (i.e., they oppose each other). On the other hand, there are situations where the dual innervation results in a unilateral cooperative response (for example, the urinary system is innervated by parasympathetic and sympathetic nerve fibers that exhibit cooperative effects).
