The loops of Henle create a concentration gradient in the interstitial fluid surrounding the loop, with the concentration highest in the and lowest in the of the kidney. Group of answer choices
cortex;
inner medulla inner medulla;
cortex outer medulla;
cortex cortex;
outer medulla outer medulla;
inner medulla

inner medulla; cortex

Explanation:

Loop of Henle is a U shaped tubular structure present in the nephron which is known to maintain a concentration gradient in the nephron.

The loop of Henle is present below the proximal tubule which is present in the renal cortex and loop is located in the renal medulla of the kidney.

The loop of Henle creates high concentration gradient in the inner medulla due to which water is reabsorbed in the descending tubule. The ascending limb is permeable to ions but impermeable to water which leads to low concentration gradient in the cortex.

Thus, inner medulla; cortex is correct.

links? do you have a link? i don't see anything?

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.  

hope this
