B. Consumers living on the West Coast with high household incomes = demographic.
C. Senior citizens (65 years and older) = psychographic.
D. Long-haul truck drivers and college students = demographic.

Senior citizens (65 years and older) = psychographic.

Explanation:

Psychographic segmentation is simply segmentation that is based on the psychological characteristics of the consumer such as lifestyles, personality, social class etc while Demographics is the study based on factors like sex, age, and race.

Base on the above explanation, "Senior citizens (65 years and older) = psychographic" is the answer. It should be noted that this is demographic related and not psychological.

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.'
