Final answer:
The correct answer is B. work together to perform a single task, as systems, particularly in biology, consist of organ systems where each organ contributes to a specific function within a larger collective action.
Step-by-step explanation:
The correct answer to the question “A system is made up of several parts that work together to perform a single task” is B. work together to perform a single task. This concept applies particularly to biology at the organismal level. In biology, a system, such the human body or that of any complex organism, is composed of various organ systems. These organ systems are groups of organs working in concert to carry out complex overall functions.
An example of an organ system is our digestive system, which includes different organs like the mouth, stomach, pancreas, gall bladder and intestines, each doing a part of the job necessary to digest and absorb nutrients from our food. The concept of an organ system extends to describe the teamwork between these systems, which allows organisms to function as a cohesive unit. The narrative that an organism is like an assembly line is a great metaphor; where each organ acts as a station within the assembly line, performing a specific task towards the overall goal of maintaining the body's functions.
