The correct answer is: Prions are proteins that are folded incorrectly.
These misfolded proteins have abnormal 3D structure but the cause is not clearly known. They aggregate in tissue and cause it damage and cell death. Prion aggregates are stable, meaning that are resistant to denaturation by chemical and physical agents.
Prions cause neurodegenerative diseases such as Creutzfeldt–Jakob disease (fatal degenerative brain disorder) or Gerstmann–Sträussler–Scheinker syndrome (also fatal).
Not really sure on that one but I can answer the question below called Define Osmosis. :)

Receptors are organs or cells able to respond to light,heat, or other external stimulus and transmit a signal to a sensory nerve. If you accidentally place your hand on the stove then your body wouldn’t be able to react quickly which would cause your skin to burn.
