Explanation:

Asset allocation involves dividing an investment portfolio among different asset categories, such as stocks, bonds, and cash. The process of determining which mix of assets to hold in your portfolio is a very personal one. The asset allocation that works best for you at any given point in your life will depend largely on your time horizon and your ability to tolerate risk.

Risk tolerance is your ability and willingness to lose some or all of your original investment in exchange for greater potential returns. An aggressive investor, or one with a high-risk tolerance, is more likely to risk losing money in order to get better results . Stocks have historically had the greatest risk and highest returns among the three major asset categories.

As an asset category, stocks are a portfolio’s “heavy hitter,” offering the greatest potential for growth. Stocks hit home runs, but also strike out. let’s say you determined that stock investments should represent 60% of your portfolio. But after a recent stock market increase, stock investments represent 80% of your portfolio. You’ll need to either sell some of your stock investments or purchase investments from an under-weighted asset category in order to reestablish your original asset allocation mix.

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.'
