Question

1. exercise or physical activity can reduce the risk of all the following health conditions except:

type 1 diabetes
type 2 diabetes
heart disease
certain types of cancer

Explanation:

To solve this, we analyze each option:

• Type 2 diabetes: Exercise improves insulin sensitivity and can reduce its risk.
• Heart disease: Physical activity strengthens the heart and reduces risk factors like high blood pressure, so it lowers heart disease risk.
• Certain types of cancer: Exercise is linked to reduced risk of cancers (e.g., breast, colon) via various mechanisms (hormonal, immune, etc.).
• Type 1 diabetes: It's an autoimmune condition where the body stops producing insulin, and exercise doesn't prevent or reduce the risk of developing Type 1 diabetes (though it helps manage it once diagnosed).

Answer:

A. Type 1 diabetes
