This morning you purchased a stock that just paid an annual dividend of $3.30 per share. You require a return of 9.6 percent and the dividend will increase at an annual growth rate of 4.2 percent. If you sell this stock in three years, what will your capital gain be

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.'

answer; /// egg production using the factory technique falls less than with the free range technique;
