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?

Kragl and colleagues (2009) performed an experiment in which they transplanted limb tissue from a salamander whose cells expressed green fluorescent protein (GFP) into different regions of limbs of normal salamanders that did not have the GFP transgene. If they transplanted the GFP-expressing limb cartilage into a salamander limb that did not contain the GFP transgene, the GFP-expressing cartilage would integrate normally into the limb skeleton. They later amputated the limb through the region containing GFP-marked cartilage cells. The blastema was found to contain GFP-expressing cells, and when the blastema differentiated, the only GFP-expressing cells found were in the limb cartilage. Similarly, GFP-marked muscle cells gave rise only to muscle, and GFP-marked epidermal cells only produced the epidermis of the regenerated limb. Which of the following phenomenon is proved according to experiment?
