Explanation / Answer

Answer=

1.) which one of these is lined with endoderm?

-f) archenteron is lined with endoderm

explaination-

-a) chorion -is lined with mesoderm

-b) blastodisc - -is lined with mesoderm

-c) allantois - -is lined with mesoderm

2.) Forms the primitive gut.

-b) blastodisc - is the dorsal part of yolk sac from which the primitive gut developes.

3.) Mass of cells found on top of the yolk

-b) blastodisc - is the mass of cells found on the top of the yolk
