Question

what is an amniotic egg? when the embryo uses a yolk to stay nourished when there is no liquid inside of the egg when the outside of the egg is encased in a membrane when the embryo grows inside a membrane in the egg

Explanation:

An amniotic egg is defined by having an amniotic membrane that surrounds and protects the developing embryo, creating a fluid-filled cavity. The other options are incorrect: yolk nourishment is not unique to amniotic eggs, amniotic eggs do have internal fluid, and the key feature is the internal membrane around the embryo, not just an outer membrane.

Answer:

D. When the embryo grows inside a membrane in the egg
