Question

Quizplus · Accepted Answer

In the roundworm Caenorhabditis elegans, the development of the vulva begins when the anchor cell secretes EGF (Epidermal Growth Factor), which then binds to the EGF receptor on a progenitor cell. This signaling pathway is crucial for the proper development of the vulva in C. elegans.
