Correct answers: chemicals in the body and senescence.

- Chemicals in the body (hormones, growth factors, metabolites, signaling molecules) regulate gene expression.
- Senescence (cellular aging/stress) alters gene-expression programs.

Protein synthesis is a downstream consequence of gene expression (not a determinant). "The brain" is an organ — it can produce signals that affect gene expression, but it is not itself a general determinant in the way the other two are.
