Question

question 8 of 10
emphysema, gum disease, wrinkles, and heart attacks are all possible effects of which substance?
a. prescription drugs
b. illegal drugs
c. alcohol
d. tobacco

Explanation:

To determine the substance with the listed effects, we analyze each option:

• Option A (Prescription drugs): These are used for medical purposes, and while some can have side effects, the specific effects (emphysema, gum disease, wrinkles, heart attacks) are not typical of prescription drugs in general.
• Option B (Illegal drugs): Illegal drugs have various effects, but the combination of emphysema, gum disease, wrinkles, and heart attacks is more characteristic of tobacco use than illegal drugs as a broad category.
• Option C (Alcohol): Alcohol's effects include liver disease, impaired judgment, etc., but emphysema (a lung condition related to smoking) and gum disease from tobacco - related factors are not primary alcohol - related effects.
• Option D (Tobacco): Smoking tobacco is linked to emphysema (due to damage to lung tissue), gum disease (from nicotine and other chemicals affecting oral health), wrinkles (due to reduced blood flow and collagen damage), and an increased risk of heart attacks (from plaque buildup and blood vessel damage).

Answer:

D. Tobacco
