A customer owns 100 shares of an NYSE listed preferred stock and notices that the typical daily trading volume in the issue is less than 1,000 shares. The customer wants to sell the stock and asks his broker what will happen if there is no ready buyer for the stock. The broker should respond that the Specialist (DMM) on the NYSE flooris obligated to buy the stock at the current market. Specialist/DMMs (Designated Market Makers) are obligated, under NYSE rules, to make a continuous market in the assigned stock. Thus, on the NYSE floor, a customer is always assured that the trade will be executed - however the price at which the trade is executed is always subject to market conditions.

The broker should respond that the Specialist (DMM) on the NYSE flooris obligated to buy the stock at the current market.

Explanation:

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.'
