Under its executive stock option plan, Q Corporation granted options on January 1, 2021, that permit executives to purchase 15 million of the company's $1 par common shares within the next eight years, but not before December 31, 2023 (the vesting date). The exercise price is the market price of the shares on the date of grant, $18 per share. The fair value of the options, estimated by an appropriate option pricing model, is $4 per option. No forfeitures were anticipated; however, unexpected turnover during 2022 caused the forfeiture of 5% of the stock options. Ignoring taxes, what is the effect on earnings in 2023

answer; enforce the rules;

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.'
