Constitutively active Ras proteins (RasD) 

Replacement of the normal glycine 12 with any other amino acid (except proline) blocks the functional binding of GAP proteins and in essence “locks” Ras in the active GTP-bound state.

Foraging Behavior - The Search for Food

Optimizing its foraging behavior

1. When the difference between the energetic benefits of food consumption  and the energetic costs of food gathering is maximized.

2. Animals with optimal foraging strategies will have more available energy with which to survive and reproduce.
