Final answer:
The collection of tasks and responsibilities performed by one person is called a job or role, which includes specific duties for which the individual is accountable in their personal, professional, or community life.
Step-by-step explanation:
The collection of tasks and responsibilities performed by one person is often referred to as a job or a role within an organization or society. Having a set of responsibilities means that a person is held accountable for certain processes and/or outcomes. In the workplace, for example, managers typically establish expectations for an individual's responsibilities, which may range from specific daily activities to overall project management. It is critical for individuals to understand their responsibilities, whether in a personal or civic context, as these are the obligations they take on to contribute to their families, organizations, or communities. A good example is within a bureaucracy, where there is a clear division of labor, and each person is tasked with a specialized role; such divisions are designed to improve efficiency, though they must be balanced by the need for flexibility in certain situations.
