Question

1. which of the following best represents the correct order of organization of living and nonliving matter?

a. atom → cell → molecule → tissue → organ → organ system → organism
b. atom → molecule → organelle → cell → tissue → organ → organ system → organism
c. cell → tissue → molecule → atom → organ
d. molecule → atom → cell → tissue → organ

Explanation:

To determine the correct order of organization of living and non - living matter, we recall the hierarchical structure. Atoms are the basic building blocks. Atoms combine to form molecules. Molecules then form organelles (in cells). Organelles are part of cells, which are the basic unit of life. Cells form tissues, tissues form organs, organs form organ systems, and organ systems form an organism.

• Option A is incorrect because atoms form molecules before cells, not the other way around.
• Option C has an incorrect order as cells are made of molecules and atoms, not the reverse order shown.
• Option D is incorrect as atoms form molecules, not the other way around.
• Option B follows the correct order: Atom → Molecule → Organelle → Cell → Tissue → Organ → Organ System → Organism.

Answer:

B. Atom → Molecule → Organelle → Cell → Tissue → Organ → Organ System → Organism
