b. the game has a nash equilibrium in which dr. smith does not advertise and dr. jones does advertise.
c. the game has a nash equilibrium in which dr. smith advertises and dr. jones does not advertise.
d. the game has a nash equilibrium in which both optometrists advertise.
e. the game has a nash equilibrium in which both optometrists do not advertise.

whats the

ans.

heterothermic organisms include those organisms that can switch between homeothermic (having body temperature higher than environment) and poikilothermic (having variation in internal body temperature) strategies.

some migratory birds show heterothermy as they decrease their metabolic rate during cold nights to keep their body temperature low. drop in metabolic rate allows increase in production efficiency of birds that reduces the internal body temperature to make it equal to external cold temperature during cold nights.

thus, the correct answer is 'birds allow their temperature drop in order to increase their production efficiency.'

hi there, i would say your answer is:

b. there is a fixed quantity of resources and technology available.

hope that : )
