Question

E: zygote and neurula During embryonic development within the deuterostomes, the waste materials produced during embryonic metabolism collects in a special sac found within the amniote egg known as: A: chorion B: amniotic sac C: bladder D: yolk sac E: allantois During development in triploblastic organisms, the three primary germ layers interact with one another through specific factors in a process known as and organs. A: differentiation B: induction C: gametogenesis D: morphogenesis 12. to form tissues

Explanation / Answer

11. Amniote egg of Deuterostomes contains four sacs namely the yolk sac in which the nutritive proteins are stored; the allantois, in which waste materials from embryonic metabolism is collected; the amnion, in which the fluid for bathing of embryo is collected; and the chorion , which interacts with the outside environment, selectively allowing materials to reach the embryo. Therefore your answer is E: allantois.

12. Morphogenesis in triploblastic organisms is important for creating the three germ layers of the early embryo and for building up complex structures during organ development. Therefore your answer is D: morphogenesis.
