Question
Chapter 47.3, Problem 3CC
Summary Introduction
To explain: The possibility of a second embryo when the ventral cells are induced to express large amounts of a protein that inhibit BMP-4.
Concept introduction:
Inactivation of bone morphogenetic protein-4 (BMP-4) allows the cells that are present on the dorsal side to develop into male dorsal structures.

The BMP-Nodal gradient so vital to amphibian and fish development may be critically important in other vertebrates (including humans) as well. Moreover, can any field of pluripotent cells (such as human embryonic stem cells)respond to gradients of BMP and Nodal signals?
Please asap
In mosquitoes,
(i) Moult inhibiting hormone (MIH) or Juvenile hormone which is most effective. Why?
(ii) Give alternative or synthetic forms of these (MIH & JH) substances.
