Question

which is a factor that influences the development of cardiovascular disease?

Explanation:

Smoking is a well - known risk factor for cardiovascular disease. It can damage blood vessels, increase blood pressure, and reduce the amount of oxygen in the blood. Bacteria growth is more related to infections like pneumonia or sepsis. Lack of calcium is mainly associated with bone health issues (e.g., osteoporosis). Sun exposure is related to skin conditions (e.g., sunburn, skin cancer) rather than directly to cardiovascular disease.
