The mechanisms for producing the medullary osmotic gradient require active transport of sodium and chloride ions from the ascending limb of the loop of Henle. active transport of sodium and chloride ions from the ascending limb of the vasa recta. the ascending limb of the loop of Henle to be permeable to water. the vasa recta to be impermeable to water. both A and B

The osmotic concentration of seawater is approximately 1,000 mOsmol L-¹. Which of the following marine vertebrates can drink seawater without becoming dehydrated? A. A bony fish such as the flounder (maximum urine osmolarity = 340 mOsmol L-¹) B. A marine bird such as an albatross (maximum urine osmolarity ≈ 640 mOsmol L-¹) C. A marine reptile such as a loggerhead turtle (maximum urine osmolarity ≈ 320 mOsmol L-¹) D. A marine mammal such as a whale (maximum urine osmolarity ≈ 1,920 mOsmol L-¹) E. All of the above

Once the maximum temperature of an organism is exceeded, denaturation and cell death will occur.  true / false
