Punctuated equilibrium occur when the environment is rapidly changing  eliminate.

Answer: Option B

Tobacco use and exposure to secondhand smoke. Poor nutrition, including diets low in fruits and vegetables and high in sodium and saturated fats. Lack of physical activity.

Some causes of chronic diseases include: tobacco use and exposure to secondhand smoke- secondhand smoke is when the people/person around you is/are/were smoke/smoking, not you- Poor nutrition- including diets low in fruits and vegetable and high sodium and saturated fats-. Lack of physical activity is also another cause.

To prevent a chronic disease from happening, you should control what kinds of food you eat to maintain a healthy diet. If someone in the room with you starts smoking, you should politely ask them to stop or exit the room. If someone asks you if you want to smoke, say no. Exercise at least 15 minutes a day.
