Question

Accepted Answer

### Question 1
# Brief Explanations:
A risk factor is something that increases the chance of developing a health problem. For example, smoking is a risk factor for lung cancer as it damages lung tissue and increases cancer - causing mutations. A protective factor is something that decreases the chance of a health problem. Regular exercise is a protective factor for heart disease as it helps maintain healthy blood pressure, cholesterol levels, and weight, reducing the strain on the heart.
# Answer:
Risk factor example: Smoking (increases lung cancer risk). Protective factor example: Regular exercise (decreases heart disease risk).

### Question 2
# Brief Explanations:
If a risk factor is non - modifiable (like age or family history of a genetic disease), we can focus on modifiable factors. For example, if family history of heart disease (non - modifiable) is present, we can improve diet (eat more fruits, vegetables, less saturated fat), exercise regularly, manage stress, and get regular health check - ups to monitor and manage related health markers (like blood pressure, cholesterol) to reduce overall health risks.
# Answer:
When a risk factor is non - modifiable, focus on modifiable factors: improve diet, exercise, manage stress, and get regular health check - ups.

### Question 3
# Brief Explanations:
A family history of a disease means that one or more family members (like parents, siblings) have had that disease. This often implies a possible genetic or shared environmental (like family diet, lifestyle) link, and it may increase an individual's risk of developing the same or related diseases due to inherited genetic traits or exposure to similar risk - promoting environments.
# Answer:
A family history of a disease means one or more family members have had the disease, suggesting a possible genetic or shared environmental link and increased personal disease risk.

### Question 4
# Brief Explanations:
Behaviors adopted today, like a sedentary lifestyle (sitting a lot, not exercising) or a healthy diet (eating nutritious foods), can affect adult health. Sedentary behavior can lead to obesity, heart disease, and diabetes in adulthood. These behaviors persist because they become habits (neural pathways are formed for routine actions), and environmental factors (like easy access to junk food, lack of safe exercise spaces) or psychological factors (like lack of motivation to change) support their continuation. This means today's decisions shape future health, so we should choose healthy behaviors (like regular exercise, balanced diet) now to prevent future health problems.
# Answer:
Today's behaviors (e.g., sedentary lifestyle/healthy diet) affect adult health. Behaviors persist as habits, supported by environment/psychology. Today's decisions shape future health, so choose healthy behaviors.

### Question 5
# Brief Explanations:
A plan for rest and sleep: Set a regular bedtime and wake - up time (e.g., go to bed at 10 pm and wake up at 6 am). Most teenagers need 8 - 10 hours of sleep. If currently getting 6 hours, changes could include: reducing screen time before bed (blue light from screens disrupts sleep), creating a comfortable sleep environment (dark, quiet, cool room), and avoiding caffeine in the afternoon/evening.
# Answer:
Sleep plan: Regular bedtime (e.g., 10 pm) and wake - up time (e.g., 6 am). Teenagers need 8 - 10 hours of sleep. If getting 6 hours now, changes: reduce screen time before bed, create a good sleep environment, avoid afternoon/evening caffeine.
