Answer:
Dopamine
Explanation:
Parkinson’s disease is a degenerative, progressive disorder that affects nerve cells in parts of the brain called the basal ganglia and the substantia nigra.
The neurotransmitter dopamine is produced by nerve cells in the substantia nigra and these nerve cells function in relaying information from the brain that plan and control body movement. In Parkinson's disease, the dopamine-producing nerve cells of the substantia nigra begin to die off . Symptoms such as tremor, impaired movement, stiffness, and balance problems occur when the loss of nerve cells is about 80%
I'm sorry but no body can answer this because there is no graph.
Energy is absorbed to break bonds in mgcl, and to form bonds in cacl2. Thus, the correct option is A.
<h3>
How do chemical reactions occur?</h3>
The transformation that takes place in substances, wherein atoms rearrange themselves and alter their initial state, is what gives rise to chemical processes. As a result, chemical compounds alter and produce new molecules.
A replacement reaction is the sort of reaction implied by the chemical formula Ca + MgCl2 --- CaCl2 + Mg.
In this instance, energy is absorbed during the chemical reaction to break bonds in the reactants and build bonds in the products.
