Correct answer: chemicals in the body.

Explanation: Gene expression is regulated by factors such as hormones, signaling molecules, and other chemical signals (and by transcription factors, epigenetic changes, etc.). Protein synthesis is a result of gene expression, not a determining factor; senescence and the brain can influence expression in specific contexts but are not general determinants.
