Answer:
True
Explanation:
Pacemaker cells, unlike other neurons in the body, can depolarized themselves (and therefore can fire action potentials) without the need of an external innervation of the autonomic nervous system.
Each class of pacemaker cells has its own intrinsic rate.
For example, sinoatrial node rate is 60-100 bpm (the normal heart frequency).
The atrioventricular node is also part of the electrical conduction system of the heart. When the sinoatrial node fails, atrioventricular node takes the lead (40-60 bpm).
“The key difference between braising and stewing,” he explains, “is the cut of meat. Braising is for cheaper, larger cuts of meat, such as beef cheeks. Stewing would use smaller cuts of meat that are uniform in size and it’s key to stewing that the meat is totally immersed in liquid. Both processes involve the lid being on the pot, which is also very important. Stewing would normally take place on the stove top and and braising would be typically transferred to the oven.” In case you were wondering, pot-roasting is another name for braising, he explains.
Answer:
The correct answer is option D.
Explanation:
The vasoconstriction or the narrowing of the blood vessels regulate the filtration rate of the glomerulus. The afferent arteriole vasoconstriction decreases the flow of blood to the glomerulus thus, decreases the filtration rate
The vasoconstriction of the efferent arteriole increases the glomerular filtration rate due to the increase in the blood level in the glomerular capillaries.
Thus, option D is the correct option.
