Cerrena [4.2K]

Answer:

Debit to accounts receivable $9,800, Debit to credit card Discount $200 and credit to sales revenue $10,000

Given that the credit card charges 2%; then the discount rate = \frac{2}{100}*10,000

= 0.02 × 10,000

= 200

The account receivable = $10,000 - $200

= $9,800

From the foregoing, it is obvious that the sale revenue would not be affected by this transaction. SO, the sale revenue = $10,000

o-na [289]

Answer:

<u>Nervous System</u> could be studied as a direct result of having defective nuclei and may shed light on the  cause of Parkinson .

Explanation:

<u>PASRKINSON DISEASE -:</u> Parkinson's disease is a progressive nervous system condition. Several regions of the brain are affected by the condition, especially an area called substantia nigra that regulates balance and movement.

A trembling or shaking (tremor) of the limb is often the first sign of Parkinson's disease, particularly when the body is at rest. Typically, on one side of the body, the tremor starts, usually in one hand. The head, legs , feet, and face can also be affected by tremors. Other hallmark symptoms of Parkinson's disease are rigidity or rigidity of the limbs and body, slow movement (bradykinesia) or inability to move (akinesia), and impaired balance and coordination (postural instability).

Emotions and thinking ability (cognition) can also affect Parkinson's disease. Psychiatric disorders such as depression and visual hallucinations are created by some affected persons. There is also an increased risk of developing dementia in people with Parkinson's disease, which is a loss in intellectual functions, including judgment and memory.

Hence , the answer is <u>the nervous system and other regions of brain</u> where the disease has a direct result of having a defective nuclei and may shed light on the cause of Parkinson .
