Step-by-step explanation:
The Procedures pane, Functions pane, and Properties pane are typically found within an Integrated Development Environment (IDE). An IDE is a software suite that consolidates basic tools required to write and test software. Developers use the Procedures pane to list the various procedures or methods in a program. The Functions pane provides a listing or a way to insert predefined functions available in the programming language or framework being used. Lastly, the Properties pane allows the developer to set or inspect the properties of selected objects or components within the project. These panes help organize and manage the components of software development for efficiency and ease of access.
