Final answer:
An example of dose response is the relationship between smoking and lung cancer, where increased smoking intensity and duration are strongly associated with higher lung cancer risk. Dose-response is evident in various contexts like alcohol and liver damage, sun exposure and Vitamin D, as well as exercise and weight loss.
Step-by-step explanation:
An example of dose response is the relationship between smoking and lung cancer. Research by Doll and Hill revealed a strong association between past smoking habits and the prevalence of lung cancer. Similarly, the effect of a chemical on an individual, often illustrated by a dose-response curve, is evident from the harms caused by cigarette smoke, which contains multiple chemicals associated with various cancers including lung, larynx, esophagus, bladder, and oral cavity cancers.
Smoking and Lung Cancer: The more cigarettes a person smokes and the longer they smoke for, the higher their risk of developing lung cancer and other health complications.
Exercise and Weight Loss: As physical activity increases, there is often a corresponding weight loss, up to a point where the body adapts or requires additional nutritional support.
Alcohol Consumption and Liver Damage: The more alcohol a person consumes, the greater their risk of developing liver damage, including conditions such as fatty liver disease, hepatitis, and cirrhosis.
Sun Exposure and Vitamin D Production: Moderate exposure to the sun increases Vitamin D production in the skin, but excessive exposure can lead to skin damage and increase the risk of skin cancer.
