A sole proprietorship can be defined as the business ran or operated by a single individual. They are generally self-employed and must pay the self employment (SE) tax on the income that the individual earned from the business.

The Schedule C is the income statement of the proprietor for the financial year. To complete this schedule, the profit of the business is evaluated by including all the expenses and income with the cost of the sold goods.

The resultant is called the net income (income - expenses) of the business which is also known as the taxable income of the business.

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.'
