Answer:
The best answer is "E"
NaCl leaves the ascending limb of the loop of Henle through active transport.
Explanation:
The loop of Henle is a U-shaped portion of the tubule that conducts urine within each nephron. It's principal function is the recovery of water and sodium chloride from the urine.
The ascending limb is impermeable to water. NaCl is pumped from the tubule into the interstitium in the ascending limb by active transport. This active transport enables the kidney to establish an osmotic gradient which enables the permeability of water and urea thereby allowing the kidneys to concentrate the urine.

Answer:
Proteins folded into pleated sheets or twisted into a helix(spiral) are considered to be _secondary_ structure proteins.
Explanation:
The secondary structure is characterized by the sequence of hydrogen connections in the peptide backbone among both amino hydrogen and carboxylic oxygen atoms. The secondary structure components usually form randomly as an intermediate until the protein pleats into its 3D tertiary framework.
