Which of the following amniotic membranes can be involved in the respiratory exchange of gasesin a snake embryo? SELECT ALL THAT APPLY.A. Amnion.B. Chorion.C. Respiratory lamina propria.D. Allantois.E. Yolk sac.

In snakes, as in other reptiles, the exchange of gases during embryonic development involves several amniotic membranes. These include:

A. Amnion: This is the innermost layer of the amniotic sac. While it primarily serves to protect the embryo and provide a fluid-filled environment, it can also play a role in gas exchange.

B. Chorion: This is the outermost layer of the amniotic sac. It is involved in gas exchange as it lies very close to the shell and allows for the diffusion of oxygen and carbon dioxide.

D. Allantois: This membrane serves as a reservoir for waste products, but it also facilitates the exchange of gases.

E. Yolk sac: While its primary function is to provide nutrients to the developing embryo, the yolk sac can also participate in gas exchange.

C. Respiratory lamina propria: This is a component of the respiratory tract in mammals, not a membrane found in amniotic eggs. Therefore, it would not be involved in gas exchange in a snake embryo.

So, the correct answers are A. Amnion, B. Chorion, D. Allantois, and E. Yolk sac.
