A duck egg is removed from its mother’s nest and incubated by a barnyard hen. The duckling hatches out in the presence of the barnyard hen and stays in her nest. After a couple of days, the duckling is presented with a choice between its biological mother and the hen that incubated it. The duckling approaches and follows the hen. This set of observations demonstrates the phenomenon of

1. Large family of structurally related, secreted, dimeric proteins that act as hormones and local mediators to control a wide range of biological functions in all animals. |
A. Rho |
|
2. Cell-surface receptor in which the cytoplasmic domain either has enzymatic activity itself or is associated with an intracellular enzyme. |
B. TOR pathway |
|
3. A crucial signaling protein in the PI-3-kinase–Akt signaling pathway, so named because it is the target of rapamycin. |
C. Enzyme-coupled receptor |
|
4. A kinase that is involved in intracellular signaling pathways activated by cell-surface receptors and that phosphorylates inositol phospholipids at the 3 position of the inositol ring. |
D. Phosphoinositide 3-kinase |
|
5. A group of monomeric GTPases that regulate both the actin and microtubule cytoskeletons. |
E. (TGFβ) superfamily |
