osmoregulation - Answer Regulation of solute concentrations and water balance by a cell or organism. especially vital to control the influx or withdrawal of water in hypertonic or hypotonic solutions osmoregulators - Answer more common in the animal kingdom strictly regulate their internal environments and keep water levels constant within their cells don't change their salt or water levels according to their surroundings, but maintain constant levels ACTIVE process MUST regulate...

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...
