The correct sequence going from smallest to largest is select one: a. cell - molecule - tissue - organelle - atom. b. atom - molecule - organelle - cell - tissue. c. molecule - atom - organelle - tissue - cell. d. cell - tissue - organelle - molecule - atom. e. tissue - cell - organelle - molecule - atom.

Option B, atom - molecule - organelle - cell - tissue

Explanation:

Atom is the smallest unit in any living being structure. A group of atoms combines to form molecules. A group of molecules combine to form an organelle. An organelle is a small cellular structure that is found with in a cell. Thus specific group of organelles grouped together form cells. A group of cells arranged in specific manner and specialized in specific function forms the tissue.

Hence, option B is correct.

the scientific method.

explanation:

tumor cells different from normal cells because tumor cells have a cell wall instead of a membrane.
