Lunar coast Incorporated issued BBB bonds two years ago that provided a yield to maturity of 12.5 percent. Long-term risk-free government bonds were yielding 8.5 percent at that time. The current risk premium on BBB bonds versus government bonds is half of what it was two years ago. If the risk free long-term government bonds are currently yielding 7.8 percent, then at what rate should Lunar coast expect to issue new bonds?

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.'
