Given the Darrow-Yannet Diagram below, which answer would correctly describe what occurs between the ICF and ECF when a HYPERTONIC saline solution is administered to a patient intravenously? (HINT: Remember that osmolarity/concentration is on the Y-axis and volume is on the x-axis in these diagrams)

Imagine a male and a female, each of which can guard (G) or desert (D).  The number of young that a mating produces is (W).  If both parents desert, a proportion P0 of the young survive; if one parent deserts, a proportion P1 of the young survive; if neither deserts, a proportion P2 survives.  On the other hand, a parent that deserts gets (p) additional offspring from other matings (however p < W).  (A) What is the general payoff matrix?  List values/equations for (1), (2), (3), (4).     (1.5 pts each)   Guard Desert Guard (1) (2) Desert (3) (4) (B) Suppose that all young survive if at least one parent guards, but that all young die if no parent guards (including offspring from other matings).  Use your matrix to determine the ESS.  Show your work and explain your results.
