Activates

To activate means to initiate a process, make something operational, or cause something to become active. It can refer to turning on a device, starting a physiological process, or initiating a system or program. The term implies a change from a dormant or inactive state to an active or functional one. It often involves an external trigger or input that prompts the action. This trigger could be a physical switch, a chemical reaction, a specific signal, or even a set of instructions. The consequence of activation is a change in state that typically leads to a desired output or effect. The activation can also apply to emotions, feelings, and memories.
