An excise tax levied on a product will impose a larger relative burden on consumers (and a smaller relative burden on sellers) when a. the supply of the product is relatively inelastic. b. the supply of the product is relatively elastic. c. the demand for the product is relatively inelastic. d. either b or c is true

d. either b or c is true

Explanation:

Tax burden refers to who pays the tax.

Taxes increases the price of a good or the cost of production.

If demand or supply is elastic, it means that quantity demanded or supplied is sensitive to changes in price.

Demand or supply is inelastic if quantity demanded or supplied is less sensitive to changes in price.

If supply is elastic and the burden of tax falls on suppliers, suppliers would reduce the quantity supplied

If demand is inelastic and the burden of tax falls on consumers, the quantity demanded would not change as a result of price increase.

In this case, greater burden of tax should fall on consumers.

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.'
