Which of the following play(s) a role in determining a person’s weight? (Select all that apply.) (2 points) Responses heredity heredity activity level activity level body mass index (BMI) body mass index (BMI) body composition

The following factors play a role in determining a person’s weight:

- **Heredity**
- **Activity level**
- **Body composition**

**Body mass index (BMI)** is a measurement based on a person's weight and height, but it does not directly determine a person's weight itself; rather, it is a tool used to assess weight relative to height. Therefore, while BMI can be relevant in discussions about weight, it doesn't directly influence it in the same way that the other factors do.

So, the correct selections are:
- Heredity
- Activity level
- Body composition
