Which of the following is the correct sequence, going from simplest to most complex, in the levels of structural organization of the human body:

a. chemical level, cellular level, tissue level, organ level, organ system level, organismal level

b. cellular level, chemical level, tissue level, organ system level, organismal level, organ level

c. cellular level, chemical level, tissue level, organ level, organ system level, organismal level

d. chemical level, tissue level, cellular level, organ system level, organ level, organismal level

e. cellular level, tissue level, chemical level, organ level, organ system level, organismal level

The correct answer is option A.

Explanation:

Cellular organization is one of the characteristics of life that states that each living organism is made up cell or more than one cell, that is made up by organization of various components such as chemicals like micro molecule that form the macro molecule and these chemical level structural organization is formed together to make cells and this level of organization makes the tissue which is complex to cell but simpler to organ that is makeup of various together.

The makeup of organs is necessary as organs are the structural level that individuals facilitate the function and make up the organ system that is a complex system made up of organs that are similar in their function. The organism is the most complex of all levels.

Thus, the correct answer is option A.
