Answer:

The correct answer is C. Normal host cellular prion proteins (PrPC) are converted into scrapie proteins (PrPSc).

Explanation:

Prions are the infectious proteins that cause neurodegenerative diseases in both animals and humans. In humans, it causes various diseases like Creutzfeldt-Jakob disease, kuru. Collectively these diseases are called spongiform encephalopathies.

Humans contain normal cellular prion protein denoted as(PrPC) and the prions are abnormal form of this protein i.e., PrPSc where Sc indicates scrapie. This abnormal protein is misfolded form of normal prion protein.

When this misfolded prion protein enters the host body it converts all the normal cellular prion proteins in scrapie protein causing a fatal disease. In this disease, holes are created in the brain tissue and tissue degeneration gives brain appearance like sponges. Therefore the correct answer is C.

Select the correct statement about the function of myocardial cells. A. Each cardiac muscle cell is innervated by a sympathetic
Evgen [1.6K]

Answer:

Option-D

Explanation:

The myocardial cells form the cardiac muscle present in the heart. The heart receives its signal from the autonomic nervous system but not all the cells receive the signals.

The SV and AV node present in the upper heart produces the potential for the contraction. The action potential gets transferred through the cell and finally reach the lower ventricle through Purkinje fibres.

This allows the contraction of both the ventricles simultaneously and sows that the heart cells contract simultaneously.

Thus, Option-D is the correct answer.
