Quizlet the countercurrent arrangement of the two limbs of the loop of henle becomes a multiplier of electrolyte concentration due to which other characteristic? question 1 choices choice a., water permeability of the descending limb choice b., water impermeability of the ascending limb choice c., active transport of electrolytes out of the ascending limb choice d., thickness of the ascending limb

The process of counter-current multiplication occurs in the kidneys where the osmotic gradient is produced with the use of energy to reabsorb water from the tubular fluid and generate concentrated urine.  

The main objective of the loop of Henle is to minimize the volume of water and the solutes within the urine without creating any modifications in the concentration. A hypertonic medulla is established by using counter-current multiplier. The three components taking part in the procedure are thin descending limb, thin ascending limb, and thick ascending limb.  

The descending limb is permeable to water, but not to solutes. Thus, the osmolarity of the peritubular space enhanced that pulls out more water out of descending limb.  

The thick ascending loop is not permeable to water, however, solutes like Na+, K+, and Cl- are pumped actively out in the proportion 1: 1: 2. Thus, the solute concentration of the fluid is greater in the ascending limb making active transport of more electrolytes.  

Hence, the correct answer is option C, that is, active transport of electrolytes out of the ascending limb.  

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
