Answer: osmosis
Explanation: osmosis is the movement of the water molecules from a region of high concentration of solute to a region of low concentration of solute, through a semi-permeable membrane.
This movement occurs until the concentration on both sides is on equilibrium.
Semi permeable membrane allows the movement of water only but not the solute.
In this case,water moves from region A to region B.
Answer: The actual answer is sample B.
Explanation: Igneous Rocks are either known as Intrusive Rocks which are crystallize that form underneath the Earth's Surface, and Extrusive Rocks which are known as volcanic rocks.
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.
