Felicia knits scarves and sells them to her friends. the first week, she knits four scarves and sells three for $50 each. the next week she buys her yarn at a discount, so she knits six scarves and is able to sell five for $40 each. which number represents quantity demanded at $40?

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.'

answer; bootstrapping is your answer;

i would say iii (3) because in order to compare a price you have to use as a reference other near stores because it's its
