Question

circle the letter or highlight the correct answer. 1. what is the basic building block of matter? a. cell b. atom c. molecule d. organ

Explanation:

To determine the basic building block of matter, we analyze each option:

• Option A (Cell): Cells are the basic units of life, not matter in general.
• Option B (Atom): Atoms are the fundamental units that make up all matter. Elements are composed of atoms, and compounds are made of atoms bonded together.
• Option C (Molecule): Molecules are formed when two or more atoms bond, so they are not the basic building block.
• Option D (Organ): Organs are structures in living organisms, made of cells and tissues, not related to the basic building block of matter.

Answer:

B. Atom
