The assumption that preferences are complete: Group of answer choices means that a consumer will spend her entire income. means that the consumer can compare any two market baskets of goods and determine that either one is preferred to the other or that she is indifferent between them. is unnecessary, as long as transitivity is assumed. recognizes that there may be pairs of market baskets that cannot be compared.

means that a consumer will spend her entire income. means that the consumer can compare any two market baskets of goods and determine that either one is preferred to the other or that she is indifferent between them

Explanation:

In the case when the presumption is to be considered as completed means that the consumer would able to spend her overall income. That means the consumer could compared any kind of two markets for the goods and measures which one is to be preferred over the other or it is indifference between them

So as per the given situation, the first option is correct

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.'

employers prefer to hire ingenious, resourceful people because ingenious people may be more liable to engage in unethical deportment as they can cerebrate outside of the box
