$ 25,000

Explanation:

The net worth of the business is $ 62,500, (Assets $ 100,000 - Liabilities $ 37,500). The increase in net worth compared to last year is $ 30,000.

Since the income was $ 55,000 and increase in net worth is $ 30,000, the remaining balance was used for expenses i.e. $ 25,000

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.'
