Answer:
sympathetic stimulation
Explanation:
Under stress or emergency conditions, the preganglionic neurons of the sympathetic division release acetylcholine. Acetylcholine stimulates secretion and release of epinephrine and norepinephrine from the adrenal medulla. These hormones enhance the effects of the sympathetic division of the autonomic nervous system (ANS) during stress. Epinephrine and norepinephrine augment the fight-or-flight response as they increase the heart rate and force of contraction, the output of the heart, and blood pressure. They also increase blood supply to the heart, liver, and adipose tissue. The airways to lungs become dilated and there are increase blood levels of glucose and fatty acids.
The Ovaries produce hormones, that trigger menstruation. They also release one egg each month for possible fertilization.

Answer:
The correct answer is E.-2
Explanation:
Net charge or electric charge is the physical property of the matter, which makes it to experience a force, when it is placed in an electromagnetic field. The unit of charge is Coulomb, C.
Types:
Thee are 2 types of electric charges:
1- Positive Charge
2- Negative Charge
How to calculate net charge?
First we have to look at the composition or our element. Then simply add the number of protons then substrate the total electrons present.
