Answer:
B) the parasympathetic nervous system
Explanation:
The parasympathetic nervous system is a division of the autonomic nervous system. Once the stress or emergency conditions are over, the activation of the parasympathetic nervous system calms down the person. This division of the nervous system slows down the responses generated by the sympathetic nervous system during stress conditions. The parasympathetic nervous system activates digestion and absorption of the nutrients, slows down the breathing and heart rate so that the energy level of the body cells is restored. After a football game, the activated parasympathetic nervous system will calm down David.
yes, it is a correct answer
The right answer is A: intercellular communication.
An example of intercellular communication is the one between the kidney, liver and lungs to preserve water-soluble homeostasis.
Angiotensinogen, an inactive protein produced by the liver, circulates in the blood. It is the precursor of the active peptides angiotensin I and II, and the only substrate of renin.
In the event of a drop in the pressure in the renal artery, renin (an enzyme sometimes considered as a hormone) is secreted in the kidney by differentiated myoepithelial cells of the arteriole afferent of the juxtaglomerular apparatus. There are also other stimuli promoting renin secretion: decreased natremia in the distal convoluted tubule, ß-agonists, hyperkalemia, PGI2 and stimulation of juxta-glomerular cells by the sympathetic nervous system)
The angiotensinogen is cleaved by the renin and forms a decapeptide called "angiotensin I", inactive.
Angiotensin I will then be converted primarily to angiotensin II by a carboxypeptidase, the angiotensin converting enzyme. This enzyme, secreted by the liver, acts at the pulmonary level.
The sex of mammals is determined by b. the type of sex chromosomes received. A mammal who receives XX is female. A mammal who receives XY is male. Any other combination of sex chromosomes is typically a genetic disorder.
