On January 1, 2020, a company issued $400,000 of 10-year, 12% bonds. The interest is payable semi-annually on June 30 and December 31. The issue price was $449,849 based on a 10% market interest rate. The effective-interest method of amortization is used. Rounding all calculations to the nearest whole dollar, what is the interest expense for the six-month period ending June 30, 2020

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.'
