Answer 1

Answer: (B) Inhibition of calcium and sodium reabsorption.

( The mechanism of action of the diuretic is that it increases the rate of urine formation and inhibits the reabsorption of sodium and calcium.)

Answer:(C) Increased cellular matrix

( The increased cellular matrix gives favour and enhance tumor metastasis.)

Answer: ( B) Destruction of adrenal gland.

( Addison's disease occurs due to inhibition of the adrenal gland where the hormones doesn't producrd sufficiently.)

Answer: (A) Glandular epithelial cells.

( The adenocarcinoma cells have characteristics of glandular epithelial cells)

Answer: ( E) Neutrophils

( Neutrophils are essential part of immune system which destroy cancer cells)
