Current drug therapies or neuroprotective methods do not provide sufficient help to patients with Parkinson's disease.

A promising new treatment for Parkinson's disease involves injecting fetal tissue into the brain of the patient to
replace damaged brain cells and compensate for the loss of essential nerve cell groups.
A clinical trial was recently set up in Colorado to determine the effectiveness of this treatment. The trial involved
40 patients with Parkinson's disease. Twenty were given the fetal tissue and 20 were not.

Identify the explanatory variable in this study and sketch a graphic of the experimental design.

step-by-step explanation:

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
