. GlobalTech wishes to invest a total of $1,000,000 in employee retention programs next year. They have identified five different strategies that will yield a return on each dollar that is spent. They wish to maximize their expected return by investing in a mix of these strategies. Assume that the return on investment remains fixed and once their investment plan is selected they do not change their mind. The retention plans offered are:

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.'

the answer to this question would be shared investment
