d) like placental mammals, their embryos feed exclusively on yolk accumulated in the egg.
e) like placental mammals, their embryos get rid of nitrogenous excreta through the placenta.
2) (UFRRJ) Below are the embryonic annexes that are formed during the embryogenesis of most mammals. The exclusive embryonic attachment of mammals and which allows a longer period of development of the embryo inside the maternal organism is:
