Four students were discussing muscle. They each has a different idea about whether muscles are alive. Bao: I think muscles are nonliving because their cells do not reproduce.

Akhim: I think muscles are living because they are made up cells.

Tony: I think muscles are nonliving because they do not exist as singlecelled organisms.

Millie: I think muscles are living because they are inside of our bodies.

Explain why you agree with that person.
