Question 2

what is ordered complexity?

Answer 2

All living things are both complex and highly ordered. your body is composed of many different kinds of cells, each containing many complex multicellular structures( non-living things my also be complex, but they do not exhibit this degree of ordered complexity)

Question 3

what is sensitivity?
