Answer: Option A.
nephron loop multiplies the concentration of salts in the interstitial fluid of the kidney medulla.
Explanation:
countercurrent multiplier is a system that utilize energy that create osmotic gradients and enable reabsorption of water thereby increase concentration of urine. The countercurrent multiplier uses electrolyte pumps there by making the nephron loop increase the concentration of salts in the interstitial fluid of the kidney medulla because it allows the nephron to reabsorb alot of water and and increase the concentration of urine for excretion while at the same time using as little energy as possible.
The answer is; D
The structure is formed by the vascular cambium. In dicots, the phloem forms around the xylem hence the xylem forms the wood of the plant while the phloems form the bark. The cambium present between primary xylem and primary phloem continues to divide to form the secondary vascular tissues.
