If the production function of ideas is as follows: then the function exhibits:

a. Increasing returns to the ideas stock but decreasing returns overall
b. Constant returns to the ideas stock and labor
c. Decreasing returns to the ideas stock but increasing returns overall
d. Decreasing returns to the ideas stock and labor

Option c. Decreasing returns to the ideas stock but increasing returns overall

Explanation:

In economics, the challenge will be to increase the production of the goods and render more services. However, the return to the flattening curve means that there would be a change in the trends. Thus, in this case, there would be a variability in the supply and demand chain. Such tends to happen with drastic changes in the trends.

the page presents four different kinds of threats that volcanoes pose and what to do before, during, and after an eruption.

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.'
