g An asset was purchased for $120,000 on January 1, 2010 and originally estimated to have a useful life of 10 years with a residual value of $10,000. At the beginning of 2012, it was determined that the remaining useful life of the asset was only 4 years with a residual value of $2,000. Calculate the 2012 depreciation expense using the revised amounts and straight line method

Annual depreciation= $24,000

Explanation:

First, we need to determine the accumulated depreciation until 2012:

Purchase price= $120,000

Useful life= 10 years

Salvage value= $10,000

Annual depreciation= (original cost - salvage value)/estimated life (years)

Annual depreciation= (120,000 - 10,000) / 10

Annual depreciation= $11,000

Accumulated depreciation= 11,000*2= $22,000

Now, we can calculate the new annual depreciation:

Useful life= 4 years

Salvage value= $2,000

Annual depreciation= [(120,000 - 22,000) - 2,000] / 4

Annual depreciation= $24,000

answer; i believe the correct answer is (180)

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.'
