Which of the following statements is false? a) holding cash has the opposite effect of leverage on risk and return. b) we use the market value of the firm's net debt when computing its wacc and unlevered beta to measure the cost of capital and market risk of the firm's business assets. c) since the wacc does not change with the use of leverage, the value of the firm's free cash flow evaluated using the wacc does not change, and so the enterprise value of the firm does not depend on its financing choices. d) even if the firm's capital structure is more complex, the wacc is calculated by computing the weighted average cost of only the firm's debt and equity.

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.'
