Answer 1

Gene expression is influenced by several factors, but among the options provided, the most relevant is **chemicals in the body**. These can include signaling molecules, hormones, and other biochemical factors that can influence whether specific genes are turned on or off.

The other options, like senescence, protein synthesis, and the brain, play more indirect roles or are consequences of gene expression rather than direct determinants.
