If your 3 year preventative maintenance plan is $896 and the cost of brake pads is $235. What is the mean cost per year of replacing brake pads if you have owned your car for 3 years and replace your brake pads one time? Round your answer to the nearest dollar.

total cost = preventative maintenance plan + cost of brake pads

total cost = $896 + $235

total cost = $1,131

Mean = total cost / total years

Mean = $1,131 / 3 years

Mean = $377<<<<<answer

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.'
