1 Answer

Answer :

(1) Placenta Explanation: The placenta is an organ that connects the developing fetus to the uterine wall to allow nutrient uptake, waste elimination, and gas exchange via the mother's blood supply. 'True" placentas are a defining characteristic of eutherian or "placental" mammals, but are also found in some snakes and lizards with yawing levels of development up to mammalian levels.
