Answer: Nucleus, Cardiac Cell, Cardiac Tissue, Heart, Circulatory System, Butterfly
Step-by-step explanation:
This is the order from the smallest organism to the largest.
The Nucleus of a cell contains genetic material called DNA, making it the smallest and simplest object on this list. Next is a Cardiac cell that contains the Nucleus and several other organelles. Next is Cardiac tissue, made up of millions of cardiac cells. After is a Heart, made up of cardiac tissue. Following the heart is the Circulatory system; multiple organs with different functions make up an organ system. Last is a Butterfly, a complex organism containing multiple organ systems.
