Sayed and ann form a contract under which sayed agrees to sell ann 500 copies of a book. the contract price is $3.50 per book. sayed breaches the contract by not delivering the books to ann by the deadline. at the time of the breach, the books are available from the publisher for $4.50 each. ann's damages are:

a. $1,650.
b. $500.
c. $1,275.
d. $750

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.'
