Answer: Because epinephrine activates the fight or flight response, related to the sympathethic response in the body.
Explanation:
The function of the Autonomic Nervous System is the regulation of the system cardiovascular, digestion, respiration, body temperature, metabolism, exocrine glands, and therefore keep the internal environment constant (homeostasis). While sympathetic activity increases in stress, the activity parasympathetic predominates during rest and satiety. The adrenal medulla originates from the neural crest and is composed of neuroendocrine specialized cells and are responsible for the production of catecholamines.
Catecholamines are dopamine, adrenaline, and noradrenaline (epinephrine and norepinephrine). Epinephrine prepares muscles, lungs, and heart for more intense activity, in situations of stress. It promotes the increase in the force of contraction in the muscles and increases in the heart rate. It also leads to increased blood pressure and bronchodilation, for greater availability of O2.
Answer:
A. A pairs with U
Explanation:
In DNA, the nitrogenous bases are A, T, G, and C. In RNA, the nitrogenous bases are A, U, G, and C.
A pairs with U in RNA because it requires less energy to use uracil over thymine.
Hope that helps.
It's either the tradeoffs between conservation and economic development or the potential benefit to farmers.
