Canine Gourmet Super Breath dog treats are sold in boxes labeled with a net weight of 9 ounces ​(255 ​grams) per box. Each box contains 6 individual​ 1.5-ounce packets. To reduce the chances of shorting the​ customer, product design specifications call for the​ packet-filling process average to be set at 43.5 grams so that the average net weight per box of 6 packets will be 261 grams. Tolerances are set for the box to weigh 261±13 grams. The standard deviation for the​ packet-filling process is 1.01 grams. The target process capability ratio is 1.67. One​ day, the ​packet-filling process average weight drifts down to 43.0 grams. Is the packaging process​ capable? Is an adjustment​ needed?

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.'
