On January 1, 2018, Jordan, Inc. acquired a machine for $ 1 comma 040 comma 000. The estimated useful life of the asset is five years. Residual value at the end of five years is estimated to be $ 55 comma 000. Calculate the depreciation expense per year using the straightminusline method.

$197,000

Explanation:

Depreciation is the systematic allocation of the cost of an asset to the income statement over the estimated useful life of that asset.

It is determined as the depreciable value of the asset over the estimated useful life of the asset where the depreciable value is the difference between the cost and salvage value of the asset

Mathematically, using the straight line method , the annual depreciation

= (cost - salvage value)/estimated useful life

= ($1,040,000 - $55,000)/5

= $197,000

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.'
