Question

Which of the following is the correct order from most complex to simplest for the levels of organization in the human body?





A. cells, organs, organ systems, tissues


B. organ systems, organs, tissues, cells


C. organ systems, tissues, organs, cells


D. cells, tissues, organs, organ systems

Answer 1

It's B.
These are tricky because D is how I would've put it but it says most complex (organ systems) to simplest (cells).
Hope this helps!
