Statement 1: on average and everything else held constant, consumers prefer deferred consumption spending to immediate spending. statement 2: on average and everything else held constant, an investment that can provide a 4% return should attract more investment capital from savers/investors than an otherwise identical investment that can generate a 12% return. statement 3: all things being equal, rational savers and investors prefer to invest in an asset that provides a 12% return rather than one that provides an 8% return. statement 4: all things being equal, savers and investors prefer more risk to less risk and prefer lower risk premiums on projects exhibiting higher levels of risk.

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.'

the correct answer is d. wealthy colonists to take care of the less fortunate. hope this
