The primary symptoms of Parkinson's disease are muscular rigidity, slowness of movement, a resting tremor, and postural instability.
<h3>What are the causes of Parkinson’s disease?</h3>
- Parkinson's disease is a disorder of the central nervous system which results in unintended movements like uncontrolled shaking, stiffness, and difficulty to coordinate and balance.
- This is caused due to damage of nerve cells in the basal ganglia of brain which leads to decrease in levels of dopamine (a neurotransmitter).
- Nerve endings that release norepinephrine also get damaged.
- Initially the symptoms are mild which gradually worsen as the disease progresses.
- It leads to behavioral changes, fatigue, sleep disorders, depression.
- This disease can be controlled by taking medications which increase the level of dopamine and other neurotransmitters and by performing therapies which control body movements.

The system is open.
An open system is one where mass is able to flow in and out of the system. The mass entering this system is the water that is added to the fish tank, and the leaving mass is the waste that is generated.
The primary advantage of using this system is that the quality of the water supplied to the fish may be maintained, meaning the fish are healthy and do not have to live in waste, as they would have to if the system was closed.
ATP is an organic molecule and stands for adenosine triphosphate. It's involved in many important cell processes. ATP chemical reactions are essential because they provide the energy for biological life.
