Following statements are regarding to the establishment of ventral axis in Drosophila.

A. Ventral follicle cells synthesize Pipe. Pipe signal sulfates ventral vitelline proteins.

B. GD cleaves Snake to its active form and forms a complex with Snake and uncleaved Easter proteins.

C. Sulfated vitelline membrane proteins bind Gastrulation-defective (GD).

D. Easter protein is cleaved into its active form. Cleaved Easter binds to and cleaves Spätzle; activated Spätzle binds to Toll receptor protein.

E. Dorsal protein enters the nucleus and ventralizes the cell.

F. Toll activation activates Tube and Pelle, which phosphorylate the Cactus protein. Cactus is degraded, releasing it from Dorsal.

During a case, the parasitic worm Plagiorhynchus cylindraceus, that lives in the intestines of songbirds such as starling. They produce eggs that exit with the host feces, the feces are eaten by foraging pillbugs. The eggs hatch into a juvenile infective stage. Eventually, the infected pillbugs are eaten by birds and the life cycle continues. What will predict about these case given above?
