For the given system, drag and drop the choices from the least complex to the most complex.

Question

heart, muscle cells, circlatory system, cardiac tissue

Answer 1

To arrange the choices from least complex to most complex, we would order them as follows:

1. Muscle cells
2. Cardiac tissue
3. Heart
4. Circulatory system

This hierarchy reflects how muscle cells form cardiac tissue, which makes up the heart, and the heart is a part of the larger circulatory system.
