In a study, the independent variable is the thing that you change to see how the change produces different results. In this study, the independent variable would be the use of nicotine.
An issue which is not a possible consequence of inadequate access to health care is: D. reduced risk of developing cavities, tooth decay, and bone loss.
<h3>What is good health?</h3>
A good health can be defined as the state of having a well-balanced proportion of body fat and non-fat constituents (mass), as well as complete mental, physical, and social well-being.
<h3>How to maintain a good health?</h3>
According to the World Health Organization (WHO), an individual can develop a good body composition and good health by doing the following:
- Exercising properly.
- Eating a well-balanced diet.
- Regularly checking their body mass index (BMI).
- Avoiding the use of cigarettes and other toxic chemical substance.
- Annual wellness visits and follow-up appointments with doctors.
In conclusion, an issue which is not a possible consequence of inadequate access to health care is reduced risk of undiagnosed diseases and developing such as cavities, tooth decay, heart disease, cancer, and bone loss.

Breathing In (Inhalation)
When you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. This increases the space in your chest cavity, into which your lungs expand. The intercostal muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale.
As your lungs expand, air is sucked in through your nose or mouth. The air travels down your windpipe and into your lungs. After passing through your bronchial tubes, the air finally reaches and enters the alveoli (air sacs).
Through the very thin walls of the alveoli, oxygen from the air passes to the surrounding capillaries (blood vessels). A red blood cell protein called hemoglobin (HEE-muh-glow-bin) helps move oxygen from the air sacs to the blood.
At the same time, carbon dioxide moves from the capillaries into the air sacs. The gas has traveled in the bloodstream from the right side of the heart through the pulmonary artery.
Oxygen-rich blood from the lungs is carried through a network of capillaries to the pulmonary vein. This vein delivers the oxygen-rich blood to the left side of the heart. The left side of the heart pumps the blood to the rest of the body. There, the oxygen in the blood moves from blood vessels into surrounding tissues.

Breathing Out (Exhalation)
When you breathe out, or exhale, your diaphragm relaxes and moves upward into the chest cavity. The intercostal muscles between the ribs also relax to reduce the space in the chest cavity.
As the space in the chest cavity gets smaller, air rich in carbon dioxide is forced out of your lungs and windpipe, and then out of your nose or mouth.
Breathing out requires no effort from your body unless you have a lung disease or are doing physical activity. When you're physically active, your abdominal muscles contract and push your diaphragm against your lungs even more than usual. This rapidly pushes air out of your lungs.

Honestly, I'm not positive myself. All I can say is that overworking your joints without enough cool-down time will put you at high risk for arthritis.
