7. Which of the following shows the correct organization in the human body, from simple to most complex? *
A-nerve cell- spinal cord organ-nerve tissue-nervous system
B-nervous system-nerve cell-nerve tissue-spinal cord organ
C-spinal cord organ-nerve tissue-nervous system-nerve cell
D-nerve cell-nerve tissue-spinal cord organ-nervous system

option D

Explanation:

Cell --> Tissue --> Organ --> Organ System

Similarly ,

Nervous Cell - Nervous Tissue - Spinal cord organ - Nervous System

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.
