Vasa recta blood osmolality is critical to maintaining the countercurrent mechanisms of the nephron. where is vasa recta blood osmolality the highest?

The vasa recta blood osmolality increases as it descends into the inner medulla. The vasa recta blood serves as the countercurrent exchanger in the mechanism of the nephron in which it is responsible for exchanging the water and the salt between the loops of the vasa recta and the medullary interstitial space.

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.
