What does the principle of complementarity of structure and function mean? The age of the structure determines the function it performs. All structures perform the same functions. Functions are determined by environmental conditions, not by structure. Function reflects structure and structure determines function. - correct answer Function reflects structure and structure determines function. Which organ systems function as control sys...
