How would you need to shift the supply and demand curves in a market to result in a situation where equilibrium quantity increases while the equilibrium price change is indeterminate? a. Supply must increase while demand decreases.
b. Either supply or demand must increase.
c. Both supply and demand must increase.

C

Explanation:

An increase in supply would lead to a rightward shift of the supply curve. As a result price decreases and quantity increases.

An increase in demand leads to a rightward shift of the demand curve. As a result, equilibrium price and quantity increases.

Taking these two effects together, there is an increase in equilibrium quantity and an indeterminate change in equilibrium price

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.'
