one of the disadvantages of getting a government sponsored mortgage is they put a limit on the purchase price of the house. because the government is in charge of the mortage loan and terms, they are able to control how much money they are allowing someone to take out for the loan. not only are they incontrol, it's a lengthy process for a government sponsored mortgage.

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.'

i might look it up later.
