Question

q3. (s c.6.n.2.2) cell theory states that all living things are made of cells. which scenario would most likely cause scientists to revise cell theory? a student forgets to study cell theory for a quiz. a law is passed requiring new science textbooks. a teacher explains cell theory in a new way. a new microscope reveals structures inside cells that were never seen before.

Explanation:

Cell theory is based on scientific evidence. New evidence from a new microscope showing previously - unseen cell structures could prompt a revision. The other options (student forgetting to study, a new law for textbooks, a teacher's new explanation) do not involve new scientific discoveries related to cells.

Answer:

D. A new microscope reveals structures inside cells that were never seen before.
