A company's adjustment for uncollectible accounts at year-end would include a: Multiple Choice Debit to Bad Debt Expense. Credit to Accounts Receivable. Debit to Accounts Receivable. Debit to Allowance for Uncollectible Accounts.

Debit to Bad Debt Expense

Explanation:

When it is assessed that some receivables (due from customers who bought goods on account) may not be collectible, the required entries are debit bad debt expense and credit allowance for bad debt.

However, where the assessment concludes that the debt will not be collectible, the required entries are debit bad debt expense and credit account receivables (where no allowance had been recorded before). If an allowance had been recorded for the debt now assessed as incollectible, the entries required would be debit allowance for bad debt and credit account receivables.

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.'
