b. the constitution stipulates exactly 435 members.

c. the number has grown each decade, according to census data.

d. the number is fixed by statute?

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.'

the answer is     d. in our global economy, most job growth will be in services, but manufacturing jobs will exist, too.
