Why do individuals with spinocerebellar ataxia experience loss of muscle control, even though the ataxin-1 protein builds up only in the brain and
spinal cord?
OA.
Inclusions can build up in all body systems and can cause
debilitating effects.
OB. Genetic mutations in the ataxin-1 protein cause muscular proteins
to change shape.
boc. When the ubiquitin tagging system does not work effectively,
cellular waste can build up in the muscles.
OD.
The neurons affected by the ataxin-1 protein buildup are in a
region of the brain that manages muscle control.

Cells in the nervous system have a potential difference of 70 mv across the cell membrane separating the interior of the cell from the extracellular fluid. this potential difference is maintained by ion pumps that move charged ions across the membrane. is this an emf? select the correct answer and explanation. 1)no. the ion pumps cannot separate charges; thus, they cannot create a potential difference. 2)yes. the ion pumps cannot separate charges, but they still can create a potential difference. 3)yes. the ion pumps can actively separate charge; thus, they can create a potential difference. 4)no. the ion pumps can separate charges, but they cannot create a potential difference.
