Answer #1

(A) part is the correct answer.

Neuronal cell death during embryonic development of the mammalian brain is a normal and desirable event because During nervous system development, about one-and-half times the adult number of neurons are created. These extra neurons are then destroyed or commit suicide. This process of programmed cell death occurs through a series of events termed apoptosis. It is an appropriate and essential event during brain development

    ALS is caused by the accumulation of misfolded protein that eventually leads to neuronal cell death. Just as is the case with prion diseases (e.g., Mad Cow disease), there is a spreading effect: even the presence of a small amount of misfolded (e.g., mutant) protein can cause other WT proteins of the same kind to become misfolded, which join the large misfolded aggregate forming in diseased cells. This is the principle mechanism thought to be behind the spreading of neurodegeneration...
