Harry and Wei are married and file a joint income tax return. On their tax return, they report $44,000 of adjusted gross income ($20,000 salary earned by Harry and $24,000 salary earned by Wei) and report two dependent children. During the year, they pay the following amounts to care for their four-year old son and six-year old daughter while they work.
ABC Day Care Center $3,200
Blue Ridge Housekeeping Services 2,000
Mrs. Mason (Harry’s mother) 1,000
Required:
1. Harry and Wei may claim a credit for child and dependent care expenses of.

$1,200

Explanation:

Based on the U.S. Internal Revenue Service, Harry and Wei can claim a maximum credit of 20% of the $6000 which is a limit of dependent care expenses for 2 or more dependents as imposed by the U.S IRS.

Throughout the year, they pay $3,200 for ABC Day Care Center, $2,000 for Blue Ridge Housekeeping Services, and $1,000 to Mrs. Mason (Harry's mother). Which has a total of $6,200.

Because they cannot claim 20 percent of all child care amount which is $6,200, they can only claim 20 percent of $6,000.

Hence, Harry and Wei can claim:

$6,000 × 20% = $1,200

Therefore Harry and Wei may claim a credit for child and dependent care expenses of $1,200.

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.'
