Answer:
The correct answer is B.
Explanation:
Nitroglycerin is a medication that produces relaxation of vascular smooth muscle. This happens because nitroglycerin is converted into nitric oxide (NO) in the body. NO then activates the enzyme guanylyl cyclase, which converts guanosine triphosphate into guanosine 3',5'-monophosphate (cGMP). cGMP then activates many protein kinase-dependent phosphorylations, resulting in the <em>dephosphorylation of myosin light chains within smooth muscle fibers. </em>
This causes the relaxation of smooth muscle and as a result blood vessels dilatate.
Answer: b) Apical surface
Explanation:
The epithelium is characterized by the juxtaposition of cells and the little extracellular matrix. The region of the cell facing the free surface is the apical pole, while the opposite side is the basal pole. The apical domain is always turned to the outer surface from a closed cavity or tube. The stomach is a dilated portion of the digestive tract where the food cake is macerated and partially digested in a paste, the chimo (from Greek chymos, juice). In adults, holds 1.5L and, when extended, 3L.Given that food enters the stomach and interects with the region facing the surface, food would be in contact with the Apical surface.
The <u>proximal convoluted tubule</u> of the nephron allows the selective reabsorption of useful substances like glucose, amino acids, salts, and water into the blood capillaries.
In the nephron, the proximal convoluted tubule is located between the loop of Henle and Bowman's capsule.
It is the key part of the kidney. The most prominent function of this structure is to reabsorb water, sugar molecules, chloride, and sodium ions from the glomerular filtrate.
The reabsorption of fluids takes place when bulk volumes of sugar and water are transported from PCT to the bloodstream.

Answer:
heat; it cuases the endospore to expand allowing the stain to penetrate the structure.
Explanation:
Answer:
Do a scan to check, as this could possibly be dangerous to leave inside a person. Report it to a supervisor or someone higher up.
