Your company just purchased a piece of equipment. The maintenance cost of the equipment is estimated at $1,200 for the first year, and it is to rise by $300 each year. How much should be set aside now to have enough to cover for the maintenance cost for the next five years? Assume payments are made at the end of each year and an interest rate of 6%.

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.'
