(Hint: Consider both structure and function.)arrow_forwardHow many times did a true "kidney" evolve in the animal clade. Which cases are clearly homologous (one evolutionary origin), and which must have evolved by convergent evolution and are therefore analogous?arrow_forwardRegarding osmoregulation, what physiological and behavioral changes would occur as a fish migrates from a freshwater stream to the ocean?arrow_forward
- What is the structure of the nephron where nutrients and wastes are taken out of the blood and put into the nephron?arrow_forwardThe bodily fluids of freshwater fish contain higher concentration of dissolved solids in their surroundings, so they tend to bloat (take in water) or lose electrolytes. How can freshwater fish avoid this? 1.) By drinking lots of water? 2.) By actively transporting ions out from the gills into the water? 3.) by excreting highly concentrated urine? 4.) by resorbing ions in nephronsarrow_forwardThe only part of the nephron that originates from the embryonic ureteric bud is the (a) glomerular capsule, (b) proximal convoluted tubule, (c) nephron loop, (d) distal convoluted tubule, (e) collecting duct.arrow_forward
- Describe structure of the nephron. How is the mammalian nephron capable of creating concentrated urine? How does filtration take place?arrow_forwardMarine mammals and desert rodents both have highly efficient kidneys that produce only a tiny amount of very concentrated urine. What selective pressure shaped this trait in both animals?arrow_forwardWhy do vertebrates possess a complex excretory system?arrow_forward
- Which one of the following is extremely important for water conservation in mammals? juxtamedullary nephrons podocytes Bowman's capsule urethra ureterarrow_forwardYou are studying renal function in different species of mammals that are found in very different environments. You look at species from a desert environment and compare them with ones from a tropical environment. The desert species would be expected to havea. shorter loops of Henle than the tropical species.b. longer loops of Henle than the tropical species.c. shorter proximal convoluted tubules than the tropical species.d. longer distal convoluted tubules than the tropical species.arrow_forwardThe kidneys seen in the early embryonic development amniotes are similar to the kidneys of adult hagfish in many ways. Which of these does NOT accurately describe one of these similarities? Both have nephrons with funnels opening into the peritoneal cavity or coelem. Both rely solely on the metanephritc nephrons to produce urine. Both have pronephric tubules and mesonephric tubules. Both have pronephric (archinephric) ducts that empty into the cloaca.arrow_forward
