Answer:
C. loss of dopamine-producing neurons.
Explanation:
Parkinson's disease: Parkinson's disorder is defined as a nervous system disorder that hinders the movement of an individual.
Symptoms of Parkinson's disorder start moderately, and formerly starts with a barely noticeable tremor in one hand of an individual. Parkinson's disorder tremors are the most common and cause slowing movement or stiffness.
Parkinson's disease arises when a neuron or nerve cells, in the area of the brain that is responsible for controlling movement becomes impaired. These neurons are responsible for producing dopamine which is an important brain chemical.
A. Personal safety, pollution, and extreme temperatures
Answer:
I'm pretty sure its Anaerobic cause I took the test.
It depends on the context; it does allow gas exchange to occur, however gas exchange occurs in the capillaries of the alveoli.
Note:
<em>The upper airway not only provides a passage for air to be breathed in and out of the lungs, but it also heats, humidifies and filters the air and is involved in cough, swallowing and speech. Air goes to the lungs where gas exchange will occur. </em>
If you are still confused try looking up gas exchange diagrams for more information.
TLDR: Disagree; it does allow oxygen to flow into the lungs as the upper respiratory tract is a passageway to the lungs. However, the upper respiratory tract is NOT where gas exchange occurs because the lower respiratory tract holds the lungs which allow for gas exchange.
<span>Individuals suffering from clinical depression are more likely to suffer heart disease and heart attacks. One primary factor is that individuals who are depressed are less likely to engage in good self care strategies: they are more likely to drink and smoke, they are less likely to exercise, and they are less likely to take prescribed medications. Physically, the stress that is associated with depression may lead to plaque formation in the arteries.</span>
