ASSERTION : Mixing of oxygenated and deoxygenated blood occurs in reptilian and amphibian hearts. REASON : Mixing of oxygenated and deoxygenated blood occurs because of the incomplete partitioning of the auricle.
ASSERTION : While on going down the loop of Henle, the filtrate becomes hypotonic. REASON: The descending limb of loop of Henle is impermearble to both water and electrolytes.
ASSERTION : Rigor mortis is rigidity of muscles after death. REASON : Muscles cannot relax due to lack of ATP.
