Anatomically, how do the ureters differ in function and pathway between male and female frogs?

1. A
   In males, ureters act as urinogenital ducts opening into the cloaca; in females, ureters and oviducts open separately into the cloaca.
2. B
   In males, ureters convey only urine directly to the bladder; in females, ureters transport both ova and urine together.
3. C
   In males, ureters fuse with the rectum before entering the bladder; in females, ureters fuse directly with the ovaries.
4. D
   In males, ureters open directly to the exterior via a penis; in females, ureters empty into Bidder's canal.
