Humans produce sweat as a cooling mechanism to maintain a stable internal temperature. Which of the following best explains how the properties of water contribute to this physiological process? - ANSWER The high heat of vaporization of water allows the body to remove excess heat through a phase change of water from liquid to gas A student placed a semipermeable membrane inside a U-shaped channel with two chambers, as shown. The membrane permits the movement of water but not salt. The...

Comparative physiology of kidney function - (L32) Questions And Answers 2024 What kind of mammals only have juxta-medullary nephrons? - ANS-Desert mammals who need to conserve water. E.g. kangaroo rat, gerbils Desert mammals will have very long loops of henle. Why? - ANS-Long loops of henle means lots of NaCl pumps. This means these mammals can produce small quantities of concentrated urine (hyper-osmotic to blood) What kind of nephrons do reptiles have? - ANS-Only cortical nephrons s...
