Question

5 multiple choice 2 points the ascending limb of the nephron loop decreases the solute concentration by actively transporting ____ out of the tubule. na⁺ and mg²⁺ na⁺ and h₂o na⁺ and cl⁻ h₂o and cl⁻

Explanation:

The ascending limb of the nephron loop actively transports sodium (Na⁺) and chloride (Cl⁻) out of the tubule to decrease the solute concentration. Water is not actively transported in the ascending limb as it is impermeable to water. Magnesium (Mg²⁺) is not the main ion actively transported out in this process to decrease solute - concentration.

Answer:

C. Na⁺ and Cl⁻
