Preet just learned that he is going to be assigned for his job to Eastern Europe. The transfer is temporary. Because Preet knows that he is going to return home in a year or two, he has decided to rent out his home. He wants to make sure that someone can take care of his financial issues while he is away, particularly depositing the rent payments and paying bills. His best strategy involves naming his sister in a:

a. durable power of attorney.

Explanation:

A durable power of attorney gives a person the legal right to act on the behalf of another person such that the former will be able to handle the affairs of the latter. A durable power of attorney stays in effect even when a person is declared incapable of managing their own affairs.

It is therefore the best option for Preet here because with him being away for a little while, his sister can take care of his affairs as he is unable to do so himself and when he is back, he can simply remove his sister from the position as it is not a complicated process.

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.'
